Gaswise Plumbing and Heating

Fantastic service from the initial call to the visit to my home. Friendly, professional and nothing was too much trouble. Cleared away all the mess and sent over all the photos/videos taken for me to use in my insurance claim. Highly recommended.

EXCELLENT SERVICE AND VALUE FOR MONEY On 9th October 2026 Gaswise Banbury carried out an annual service on our Worcester Bosch Greenstar 8000 gas boiler and Gazco 8305 gas fire. The boiler was installed by Gaswise in October 2021; the gas fire was in place when we bought the property 26 years ago and could be up to 40 years old. In recent months we have considered replacing it but it is rarely used and is never a problem. Technician Jake serviced both devices and was an excellent representative of his company. He was polite and pleasant at all times and worked in a clean and efficient manner. He stripped the gas fire down completely, cleaned all the parts and re-assembled it. He found no problems and left it in working order. He worked on the gas fire for 1.25 hours and has removed from our minds any thoughts of replacing it. He spent about 45 minutes servicing the boiler. Jake left both workplaces, lounge and garage, very clean and tidy. We are very pleased with the service provided by Gaswise and, although we initially thought the pre-service quotation was a little high we now feel that Gaswise provided excellent value-for-money and peace of mind regarding the safety aspects of the gas fire, especially as we are in our eighties. Thank you Jake and Gaswise.

I’ve used this company twice now and they have done a great job for a fair price, I would highly recommend

Jake could not have been more helpful and polite. He carried out the gas fire and boiler services with a friendly professionalism and left the house cleaner than it was when he arrived. He is a real credit to the company. Highly recommended and will use again for next years servicing. Thank you

Absolutely superb from my enquiry to the repair of my boiler. Olivia was superb at dealing with my enquiry and Aidan was an absolutely superb boiler engineer and a very decent chap. I couldn't reccomend GasWise strongly enough.

Had an emergency leak around my shower seal which was going through to the kitchen - within 30 minutes, Kevin arrived, resealed the whole shower tray and check out for any further issues. Cracking job.

Great service as always. Use the company for all our plumbing/gas work. Tap replacement today and again great service and was very quickly scheduled in.

Booked a boiler service at 5pm and the engineers were at the door at 8:30 the next morning. Polite, professional and informative. Boiler serviced, small parts replaced and all done within the hour and at an acceptable price. Great service, very impressed. Thank you!

Called today to see if they could complete a gas check with certificate on a property I'm buying. They could not have been more helpful or efficient. Already sorted for first thing tomorrow. Would definitely recommend.

Excellent. Super fast repair to gas pipe

Great service from Olivia on the phone and Jake the fitter who attended. Really professional, careful and friendly. What a great person to have on the team. Thank you for your visit, Jake, and for successfully completing the job in no time.

Gas wise originally rescued our mismanaged oil boiler and have maintained it for 5 or 6 years now. Great service always. We now need to replace the 18 year old boiler and Olivia responded to my email within half an hour, we now have an appointment within the week with the expert. Fantastic service from Olivia today. I highly recommend GasWise

Great service, response was quick, advice was clear, job completed by Jake a few days later with no issues.

Excellent Service with clear communication from start to finish. Jack the engineer arrived at the planned and was meticulous with his fault finding and repair. Jack went over and above with making sure I was informed and happy before he left. The final bill was very reasonable and will be booking again shortly for work on our other properties.

Fantastic service

Really fast and good service

Woke up to find that the oil boiler was broken and no hot water. No problem; use the immersion! But that wasn’t working either. Panic! Called GasWise and Jonny was with us in half an hour and managed to get the boiler going again after immediately determining the fault (luckily had a part). We were so grateful, especially with the bank holiday approaching. Jonny is very proficient and courteous. Couldn’t have asked for better service.

Great and very efficient service

Excellent in every respect..cutomer service from Olivia when making appointment and from Grant who arrived bang on time next day at 9.00am as fixed. Blocked drain diagnosed, unblocked and all cleaned up in just under 2 hours. Perfect response just as I needed..thank you. I'll go to DrainWise without hesitation in the event of any future problem with the main drain outside my house.

Excellent! Jake came to service our gas fire and did a very thorough job. Communication was spot on throughout the process. Great to use a company that knows what customer service is all about. Would highly recommend and will definitely use Gas wise again. Thanks all.

Great Service from booking through to the execution, quick and efficient. The engineer Grant is extremely experienced and brilliant at what he does, totally recommend them.

Jack came to rectify a fault with our old gas boiler. He was extremely helpful, competent and very knowledgeable about resolving the problem. We were very impressed with the way in which GAS WISE and Jack went about the work. Our very grateful thanks for an excellent job well done. We have recently had further work carried out by GasWise Plumbing. As ever, this was performed to the highest standard. An exceptional company from admin to engineering. Our very grateful thanks to all concerned, especially Tom and Jack.

I have had a number of boiler issues recently and have received an engineer promptly. The engineers are very pleasant and leave every where clean and tidy and give explanations of what they have done. I also had a plumbing job done and again everywhere was left clean and tidy. Olivia who answers the telephone is always very helpful.

On 9 April two young engineers Harry and Liam redirected the water supply to at least 4 to 8 properties mine included. Their professionalism and knowledge was exceptional. Also Olivia who is one of the orchestrator is part of the glue that makes this a business to consider. Thank you. Peace

I am delighted with every aspect of the service that I have received from this company, communication is professional and friendly from the team on the phones, the boiler has been serviced and made safe by the plumbers who arrived on time were knowledgeable and a pleasure to have at my home they worked efficiently and were very tidy - I would not hesitate to recommend this firm

Came to help unblock sink very promptly after I was let down by another company. Gavin did great job.

Always use Grant at Gas wise to sort out my domestic plumbing. He’s professional, excellent at his job and always sorts out the problem. Gas wise are value for money and reliable and I would definitely use again and 100pc recommend. Thank you !

Exceptional service Olivia was helpful and able to offer support for all our GAS needs. Communication scored 10/10

Have just been charged £120 for this company to sort out an issue they caused! Sheisters who can’t be trusted, please do not let this company near your property. The same valve had worked fine for all the years we have lived in the house and once fitted to a new radiator by gaswise it didn’t (pretty certain this is no coincidence). When they returned to sort it took 10 minutes to diagnose and fix (releasing a stuck pin). A bit like printing money, DO NOT TRUST! I might train as a plumber as £120 for 10 minutes work sorting an issue you caused is a win win. Further to your reply I would like to point out the following facts: 1) you’re wrong this wasn’t touched by us as there’s no need and we’ve never touched it. You’re accusing me of lying and I don’t appreciate that. 2) as you’re the professionals why when re-fitting the valve wasn’t the fact it was located in the same room as the thermostat and because of that it was pretty useless anyway and there was no need to refit it? 3) speaking to people like they’re complete idiots when they are genuinely aggrieved with being ripped off doesn’t mean I was rude. Also this was the third phone call which each time I was fobbed off. I think you will all benefit from going on a customer relations course!

Very efficient and professional 👏

competent and efficient

I had call to use the heating engineers Gas wise. I spoke firstly with Olivia on the phone and explained my situation which she immediately understood and organised for a engineer to come and assess or fix my problem. Olivia was patient, understanding also very polite.Jake was prompt and very courteous. He diagnosed the problem with my heating system. Promptly, the next morning, Nick arrived unfitted. The pump and various other items to a high degree. He was very courteous and explain\n Everything he was doing. I would have no problem calling dem. In the future, for any work\n That needed doing on my heating. System.

Great Service for an emergency callout. Liam diagnosed and sorted the problem quickly and serviced the boiler at the same time. Highly recommend.

Our annual boiler service was on time and carried out professionally. We have used Gaswise for some years now and will continue to use them. Happily recommend them.

Booked them to fix a non working boiler. Came out 'fixed it' £270 and then it broke again the next day. They came back and 'fixed' it again. It broke again a week later. Came back again and 'fixed it' for the third time. Charged another £400 for this third 'fix' in 2 weeks. It was left working but incredibly noisy - unbearably noisy. And... now few weeks later - it has broke again. We are £700 down and no boiler.

Came out same day to fix and service the boiler. Aidan was polite, professional and did an excellent job.

Very professional install of a new boiler, the engineers were very polite and tidy. They turned up when they said they would and the boiler is working brilliantly. Would highly recommend GasWise, their customer service and communication was brilliant from start to finish.

I recently experienced an emergency and GasWise responded with remarkable speed and professionalism. Their prompt assistance and excellent service left me genuinely impressed. Thank you for your outstanding support.

Great service.

I was impressed with the complete professionalism of the engineer who serviced our boiler. He was such a nice friendly young man but also obviously experienced. I look forward to seeing him again next year.

Well done to the superstar 👏 Olivia at the front desk. Super helping even with a cold Great company 👌 👍 great people 👍

We’re all sceptical about what plumbers charge for what they do, but for all my decades of renovating houses, theses guys are genuine…and don’t rip you off. Olivier in the office is so professional and responsive and Jake (our plumber) won’t try to sell you a boiler for £4k if he can fix the problem. They’re trustworthy and worth every penny.

Avoid this company. After some building work took place at my home, I had a vibration in my pipe in my top floor bathroom. I called out Gas wise, who sent a young engineer. I tried to explain, many times, i believed it was pressure in the pipes, he told me that it was loose pipe work behind my tiles. I was told numerous times I would need to have my whole bathroom ripped out, tiles off wall, floor, shower, toilet, sink out. I kept saying that cant be right. He then got a spanner and just tightened the shower valve by a couple of mm. Vibration stopped. 3 days later vibration came back. I called my builder who said turn off the stop cock, then it back on but half a turn less. Guess what ..... no vibration. I fixed it. Gas wise are demanding I pay over £100 for misdiagnosing the matters. And trying to get extra work out of my by falsely saying the whole bathroom needed ripping out. I can also see they have tried to rip off others in the reviews. Being in business myself, if I'd made such an appalling error, i certainly would not be giving myself a bad name in demanding this invoice to be paid and threatening me with court proceedings Avoid.

I recently had GasWise to under go some work, and they were so helpful. They are extremely knowledgeable and professional, providing an amazing service throughout, highly recommended.

Rang GasWise as we thought we had a leak under kitchen sink. Engineer turned up within twenty minutes and worked very hard to fix several problems. Very pleased with service and leak free kitchen sink!

Serviced our boiler and installed two towel rails. Very reliable, friendly and tidy. Definitely recommend.

Our Ideal boiler is now working very well, thanks to the good GasWise engineer, Jake! Again, Jake has come to our rescue! All sorted very efficiently. We have always found GasWise staff most helpful, efficient and friendly.

Great service.

Very efficient service 👍

2nd year of using GasWise and very happy with service - thank you!

Very good service,polite engineer.Would recommend.

The GasWise team have just carried out my boiler service. They were great! Arrived very promptly, we’re friendly and polite and left everything perfect working and clean & tidy. Additionally, they installed a hive heating control system. Amazing service.. thank you.

Excellent service today from GasWise! Pre-visit and conversations with Tom were really helpful, which meant that both Jack and Aidan knew exactly what needed doing today. Very friendly team, and really knowledgable. Highly recommend them and I’ll definitely use them again.

(Aug 2024) GasWise removed a gas fire for us and did a fantastic job. Ryan and Harry were really professional and friendly. They removed all of the old parts and left the area in an immaculate state. (Aug 2025) Jake replaced two radiators for us and, whilst onsite, he also resolved a filling loop pressure issue that we had had for a long time. Jake's work was exceptional, and he was friendly, polite and professional at all times. Thanks Jake! Excellent service all round from GasWise!

Excellent job

Gas wise sent Ryan within the hour for emergency call out . Ryan fixed the problem . Polite and cleared all the mess up. Highly recommend.

Very pleased with Gaswise Service for our annual boiler service We have used Gaswise for regular servicing since they installed a new boiler 7 years ago Ryan was very efficient with a friendly attitude and nothing to much trouble I would strongly recommend Gaswise, a very well run and honest company

Brilliant service from Ryan who carried out boiler service at our home today; arrived on time, friendly and left the place immaculate, what more can you ask for! Spot on. Prices very reasonable as well. Will definitely use again next year for service.

As always excellent service. Courteous, efficient and very polite. Thank you Ryan!

Friendly, professional, and clearly skilled. Everything explained in simple terms and made sure the system was running perfectly.

We just moved in to our new property on Friday, we reported the taps not working in the kitchen on Thursday, Ryan came around, identified the problem, and changed the taps. Great, professional service, Ryan was very friendly and professional. Thank you.

Very pleased with the work completed by Gaswise’s friendly (and fast working!) engineer, Ryan.

Prombt arrival after I had called them out. Polite engineers . Explained problems and hopefully sorted them

1st class service as always. Friendly, professional, efficient & highly recommend A***** Thank you to Gaswise & Ryan who completed my annual service

Ryan completed a boiler replacement and a Landlords certificate for us on our rental property. He was friendly and efficient, and we really appreciate the effort he went to, to ensure we were happy with the installation and that we understood how to use it before he left. Thanks 🙂

Ryan arrived on time and completed the service efficiently and effectively

Jack initially came to service our boiler, he was friendly, professional and did a great job. We wanted our heating system flushed, so asked for a quote. This was sent the same day and our system was flushed through on the day we wanted, all ready for the winter months by Jack & Harry. Again a friendly professional manner, and our home left clean & tidy. Highly recommended, reliable, friendly and competitive prices.

Plumber was polite and did the service without fuss

Really good service, super helpful engineer and reasonably priced. Carried out repairs on the day of the service

Excellent service will recommend the company to my neighbour’s

.Ryan was very efficient and lovely. he arrived on time and was respectful to both myself and my property. he was friendly but just got on with the work . excellent!

Fixed the radiator back to the wall. Super quick, didn’t make a mess of the newly painted wall and tidied up nicely.

We had our boiler serviced by gaswise for the last couple of years and the service has always been great. We had Jake come over this time and he went above and beyond by sorting out a loose tap that he noticed while servicing. It may seem like a small thing but goes to show how he goes above and beyond for his customers. Thanks for your help.

Gas engineer arrived on time fitted gas cooker in know time at all and took away some polystyrene will recommend very highly

Be careful. Attended the property and didn’t fix the issue, returned the next day and suddenly claim that there were issues and they couldn’t touch the boiler. Suggested we needed to spend THOUSANDS. Second opinion (and third!) proved we did not..

Arrived on time, A very thorough and professional Boiler Service

The men that e service on the boiler were very good and they friendly and poilteý

Excellent and very prompt response to our boiler breakdown. Very pleased Nick's attention to detail and pleasant attitude when visiting us. We shall use you again.

Very professional, on time and problem fixed within an hour.

Very diligent company. Installation of two commercial boilers into a large church. Thorough site surveys carried out over three visits including specialist flue manufacturer and the boiler manufacturers. Well managed installation with excellent post installation hand over and follow up. The photos were taken during the process of install.

Very positive interaction. Needed a washing machine drain installed. Had engineer out for a quote within a few days. Received the quote back same day and was able to book engineer to attend the next day. Engineer arrived. Ensured that newly laid carpet was protected by laying matting to prevent any dirt being treaded on it. Engineer carried out the work and kept me informed all through the process. Very good install and friendly staff. Engineer tested install and had me witness ensuring we both were happy with the work Not very many companies are customer centred but GasWise Plumbing & Heating are the exception and make the customer first. Definitely will use them for future endeavours and will recommend them to others. Thank You GasWise Plumbing and Heating.

Great service, on time clean and tidy local business

I've used GasWise twice for boiler/radiator repairs. Both visits were very easy to arrange on the phone, and the customer service during the visit was great. They're attentive and happy to answer any questions before doing any work. I'd recommend them if you have any plumbing or heating needs.

Gentleman came out to put in a new radiator, yesterday for my elderly mother who is registered partially blind. He was absolutely great, especially with my mother. Has done a wonderful job. Have used this company many times and have always done a great job and the staff are really great. Also thank you to Charlie in the office

Very efficient . Neat and tidy. polite. All the things i like from about the engineer.

Excellent staff & service

Absolutely brilliant - we needed a heating engineer to cap and remove our gas fire at short notice and they were able to sort it for us! Fantastic all around and highly recommended! :)

Ryan came to cap and remove our gas fireplace tonight- he was finished in under an hour and did a fantastic job! Also a really lovely person :) thanks Ryan!

Excellent service and they answer the phone within 3 rings 🤩

GasWise installed a radiator and replaced a ball valve in our wc. Engineer was courteous, helpful and efficient.

GasWise carried out an annual service on our boiler, they were very thorough and the communication prior to coming out was great. I would highly recommend them.

An efficient and well run business. Everyone was helpful and polite, the servicing of our boiler was meticulous with explanation of works done. Would definitely recommend to others.

Excellent and efficient. All members of staff were friendly and very helpful. Would fully recommend. Thank you.

Efficient and friendly.

Excellent and friendly service, would highly recommend and would always use in the future.

Efficient, all questions answered

Gaswise were excellent. I had something that needed to be done urgently, called them in the morning and they had someone over by 3pm that day. Job done perfectly. Will be calling on them again.

Very prompt service, whole firm working to a satisfied customers. Well done everyone

Lovely plumber turned up exactly on time, fixed my loo, took away the rubbish and hoovered up all the mess. Fantastic service!

Fast and efficient service from initial phone call through to completion of initial inspection. Everyone I spoke to within the company were very helpful and professional with relevant information sent over quickly. Would highly recommend

Excellent service from Gas Wise and in particular their engineer Jake Foster. He is the first engineer in 12 years to properly service our gas boiler. By properly servicing it, I mean he actually opened the boiler, thoroughly inspected it, cleaned and tested it. Previously engineers have just stuck a probe in the unit, switched the controls on and off again and left. I will definitely use GasWise again.

GasWise have always been friendly and helpful over the years I've been their customer.

Quick and professional. Issue with the boiler was diagnosed and part replaced within an hour. Highly recommend

Disappointed. Refused to service the boiler which has been services the past many years because of its position in the showeroom

Fast, efficient, friendly service - again. Lovely people and VERY competent. Highly recommended.

Absolutely wonderful service! Can't be faulted. Friendly, reliable, efficient, highly recommend.

Engineer arrived bang on time, job was carried out promptly and with no fuss, really great job, radiator looks great and room was left really tidy. Would definitely use GasWise again and would highly recommend.

The engineer was friendly, efficient and tidied up. We would definitely recommend GasWise

Kevin came last week, sorted all the issues, prompt and polite, many thanks

We booked Gaswise for a service on our combo boiler & to check a small issue we had. Ryan attended & serviced the boiler then diagnosed what was causing the issue, he fixed this quickly for us. Throughout Ryan was polite, professional & hard-working, he worked cleanly, tidied up after himself & even took his shoes off as soon as he came through the front door, this was appreciated. The quote for the repair, on top of the original service price was very reasonable. When we attended the office to pay the invoices all of the staff were welcoming & professional.

I'm impressed with the company; they turned up on time, did the work efficiently and neatly, and cleared up afterwards. Fair prices too, in my view.

Excellent service of your team, with attention, respectful, also a fair price service. I strong recommended them! I'm sure I will call them in the future. Many thanks,

Very polite, pleasant and knowledgeable engineer.

Polite, efficient and knowledgeable. as new customers very happy to have found a decent company with decent staff. Happy and warm in our house

Excellent, professional and timely response. Our engineer (Grant) was patient, careful and polite and solved a total mystery in my kitchen so I am very grateful. He had a myriad of practical skills that he put to use in overcoming our problem and which clearly extended beyond the world of drains. I wouldn't hesitate to use this local company again.

Excellent service all round. From answering the phone to completing the job in good time, the job couldn't have been any smoother. Many thanks.

Friendly & speedy service

We had been let down by another company. Called on Friday and had a member of the team with us by Monday. Boiler repaired same day. Highly recommended company.

I've used Gaswise twice now for plumbing issues and I have always felt that they go the extra mile! Recently I was struggling to find a time I was available for them to come and do some work on my old immersion heater. But we kept trying and made it work. I really appreciate their efficency, friendliness and willingness to do whatever they can to do the jobs we've needed doing. I might add that we are a bit far out from their normal work area, but they still do their best to fit us in workwise.

Arrived on time. Professional service. Very polite engineer.

Dear GasWise Team, Huge thanks to your amazing team for completing a very challenging job in my ancient house. The professionalism, skill and kindness of all GasWise employees was outstanding. I really appreciate the work by Dan to restore my roof and Harry for braving the loft area. Nick and Ant were amazing and Jonathan and Tom's reassurance when things got tough was much needed. Sorry there was one more hero who came to disconnect the tank but I cannot remember his name. I will be recommending you to everyone I know and look forward to a long association with you in the future.

My Oil Boiler had air in the system and required purging, phoned Gas Wise in the morning 9am and they had an engineer out to me in the afternoon, they purged the system checked to make sure everything was as it should be. The two lads were friendly and professional. Cannot fault the service I received and would highly recommend them.

We had a complete re-model of our upstairs bathroom, and Dan and the Gaswise team did an absolutely amazing job - from providing a 3D render of the vision and flexibly supporting with our budget, to co-ordinating all the different tradesmen (plumbing, plastering, electrician etc) the service was seamless, quick, and well worth every penny spent. We were able to trust Dan with all the details of the fit out, and the end result was perfect, especially as we had never decorated a bathroom before so had no idea where to start apart from a Pinterest board! Thanks Dan - highly recommended to all!

So happy we chose Gaswise. Professional throughout, worked so hard to make our vision a reality, considerate , helpful when we couldnt decide what would look best, always tidied up after themselves at the end of each day and we couldn't be happier than we are with the end result. BIG thank you to Ryan, Daisy, Robin and Dan on such a beautiful job I can't put pictures on for some reason but it's definatly got the wow factor. Nothing was too much trouble for this lovely company honestly. Highly recommend 👌

So happy with our new bathroom Dan and the team at Bathroomwise fitted for us. From the tiling to the wood cladding, Dan did a meticulous job and shared our vision for what we wanted to achieve. Dan has been so helpful and responsive with any follow up questions. We love it, thank you!

We called Drain wise out for a problem with our drains , Jonny from Gas wise ( Drain wise ) arrived 20 mins before so he could take a look around and get a head start . It was a tricky one and after 2 hours of investigation in 11 manholes Jonny found the issue and the drains had been disconnected by the house builder so this has been a pain but with Jonny staying until he had found the issue really helped us as I’d still be scratching my head Thanks to all the Drainwise team

I have used GasWise 2 or 3 times and each time they have arrived earlier than expected and done excellent repairs in good time. I thoroughly recommend them.

Fantastic work carried out on a tired shower room that was long over due a refit. Dan and the team were professional, friendly with excellent attention to detail nothing was too much trouble. We are thrilled with the final results!!!

My insurance company messed me around for weeks on end. Took matters into my own hands and booked Gaswise Plumbing and Heating. They had the issue sorted out in no time. Cheers.

excellent service , particularly Jake and Aiden … brilliant team very polite would definitely use again

Always a great experience. Very helpful and professional.

Antony visited to service our gas boiler. He was very thorough and efficient and a pleasure to deal with. GasWise were recommended by a friend. My request for a service was dealt with very quickly and Antony came out the next day at the time booked. I am very happy and will use GasWise again.

GasWise did a gas boiler safety inspection. Everything was good.

Boiler service carried out today. Arrived on time. Professional and friendly. Good value for money. Will definitely use them again Highly recommended.

Dan and the team at GasWise did a fantastic job installing a shower at short notice at our new property. Nothing was too much trouble and we couldn’t be at the property while they carried out the work and they ensured that all instructions for accessing the property were followed and were polite and respectful at all times. I wouldn’t hesitate in recommending GasWise to anyone in need of plumbing, heating, bathroom installations and more. I will definitely be using them again! Mrs Abbott

Incredibly professional, way more than what i was expecting!

Service of a Worcester bosch oil boiler The engineer was great and will use again.

Very fast service, sorted boiler straight away. Both the engineer and the lady in the office were great. Highly recommended.

Professional and prompt service, well informed and helpful.

Fitted new kitchen sink and shower surround. Also fitted new parts to heating system. All very prompt and efficient at reasonable cost.

Boiler Serviced by Jake very professional and friendly member of staff

Very happy with the service received. We had a gas leak on the pipe/attachment to our cooker and had to have an emergency visit by SGN who cut off the supply until we could get the pipe replaced and the cooker tested to make sure it was safe. After being let down by another company, I rang GasWise and they said that they could come in the next couple of hours and get it sorted. They asked me to send some pictures so they could make sure they had the right parts before they arrived and the job was done in less than an hour by a very friendly and polite engineer. I will definitely use them in the future.

We changed to GasWise for our boiler service this year and very pleased with their professional and friendly service. Especially happy with how honest and trustworthy the team are. Everything was explained to us including why a valve didn't need replacing which we'd been told by a previous company needed doing. Thank you so much GasWise team!

Faulty single radiator testing and heating system controls changes. Ryan, Aidan & Daisy worked well to correct the issues.

Guy’s did a excellent job. Very professional, and polite. Price very good. Would recommend Gaswise to anyone.

Very impressed with GasWise. Quote received within one hour of visit. New boiler installed quickly. Engineer was polite, friendly helpful and very professional. Would highly recommend.

Contacted a number of plumbers who were no-where near as responsive as GasWise. My elderly mother had no heating and GasWise visited that day to ensure she was kept warm. They were so helpful and professional and my mother said the plumbers were really helpful and friendly too, puttingher at ease during the visit. Thank you so much! Highly recommend if in need of a plumber in this area.

The customer service is excellent. Always reliable and dependable. When I had a small issue with my boiler this morning and they quickly helped me figure out the root cause and solution over the phone.

Very quick and efficient service, pleasure to deal with.

Did an emergency repair in very quick time, and neatly.

Our shower cartridge was playing-up, meaning the shower wouldn't turn-off. GasWise (who had not supplied the shower) were able to attend the same day to isolate the shower. We were delighted with their speed and efficiency.

Just brilliant, called the office explained the issue. Asked me to send pics via whatsapp, which saves so much time. Half an hour later engineer at my door and less than an hour later my boiler is working again. Number saved and will be using them again for sure.

2 of our radiators had stopped working, also had a leak under the sink, the repair was dealt with very quickly. I was called twice before the agreed appointment to see if I wanted an earlier appointment which had become available. Very professional service, would definitely recommend and use again.

Called Gaswise as was having trouble with my boiler and getting no hot water. They made an appointment for me the following morning which was great and even better when I received a call from them later that day saying that they had an engineer available to call round in the next hr if that was convenient. The engineer was with me within the hour and carried out the repair. The engineer was very professional and knowledgeable and a very polite person. I would highly recommend Gaswise as I received excellent service for a very competitive price.

Very responsive and got the broken thermostat replaced on the same day calling so that the heating can back on. Much appreciated.

Really pleased with the engineers from GasWise, arrived on time and were clean and efficient when repairing my boiler.

Very professional, reasonable price, friendly service. Definitely recommend and will only use them going forward.

The engineer arrived on time and fitted a new boiler and ancillaries in a very clean and efficient manner. He was very pleasant and helpful making sure we had heat on the coldest night of the year.

A huge thank you to Tom, Jack and Kev from GasWise Plumbing & Heating Services UK Ltd for the amazing job you all did replacing Mum & Dad's boiler and the tank yesterday. You all worked you're socks off to get them back in the warmth. Fantastic bunch of lads and would highly recommend them for all heating and plumbing needs.

Nice friendly professional people. Did not mess about stuck to the task Great service and good value. Five stars.

usual boiler service uncovered a small leak. Great service addressing the issue to ensure we weren't left without a boiler.

Used Gaswise for my boiler service, very happy with the service and price, arrived on time and completed the job with no problem.

Fast efficient service. Would definitely recommend this company

We had a gas problem and they came as quickly as they could . Tom was brilliant. Our gas heating was checked and we are lovely and warm again. Thank you

Boiler serviced by Jake quickly, efficiently and politely.

First Class service, thank you

Brilliant service. You could not ask for more!🤗🤗🤗

Excellent company, always on time and polite. Good quality service, tap and sink installation, pipe redirection for gas hob, radiator fitting, connecting and testing everything. Washing machine and dishwasher installation. Would highly recommend. Did a lot of work and turned out brilliant. Would use them again. Hard working guys and the quotes were always clear and accurate.

It’s the first time I’ve used GasWise and found them to be helpful, professional and friendly.

Always a 5 star service!

Great service, they did a great job getting rid of an old radiator, and putting a new one in exactly qhere i wanted it. Very tidy work and I'm really happy with it

We have recently added both gaswise & drainwise onto the books and it was the best decision I've made since working here. They are responsive, polite, helpful and really good at what they do. I would recommend gaswise without hesitation!

They servicef our boiler, quickly, professionally and with a smile.

A great service from start to finish. I had the boiler serviced and a leaking toilet fixed. Very reasonable price, less then I was expecting. Easy to book, turned up on time, very professional service. Will definitely be using again when needed.

fantastic plumbing company. called for a toilet repair. they turned up the next day. done a professional job. i would definitely recommend them.

Oil boiler service carried out this morning. Arrived early, (good for us!) worked solidly for 2 hours+. Bill very reasonable too. Thankyou.

Removal of old gas fire and cap feed.

Boiler strip down service was carried out quickly; issue was investigated and resolved. Will use again for next year's service.

Work was done to a high standard. The engineer was on time, polite and left the place very clean. I have used Gaswise several times and have always been very happy with the work.

GasWise have been our plumbing & heating company of choice for over 10 years now! They have fitted heating systems, repaired water mains, fitted radiators and are currently assisting with house renovations and an extension! All engineers are professional, polite and do an outstanding and tidy job. An all round great company!

Service of our gas boiler. Engineers were early, polite and efficient. Consulted me on what needed to be done and completed quickly with no mess to clean up. Highly recommend

Two jobs done, both excellent

1st class service from start to finish. Friendly, reliable, knowledgeable, trustworthy, professional local company. Very easy to work with & excellent customer service. A replacement combi boiler was required as ours finally died. We'd been without hot water & often random, sporadic heating so a new boiler was required. Huge thank you to all at Gaswise who helped us, especially Ryan who was not only new to the team but tasked with our boiler installation in this heatwave that we've all just had!! 🌟 Very happy customer, highly recommend. A*****

Used Gaswise a few times now have always found them very good and will definitely use them again

Quick call out , job repaired quickly , Highly recommended!

Really efficient communication and service

Amazing service. The low pressure issue was bothering us for a long time but GasWise solved it record time. At ~11:30 I was at their office explaining my issue, at 13:00 they were at my place and at 13:10 the issue was solved. Thanks for making my day. Definetly recommend anyone to use their services.

Jack arrived on time and was polite and pleasant throughout his visit which ended in the time that was predicted. After he had finshed I asked him to look at our gas fire which we are contemplating having upgraded. This was not on his original schedule but he willingly did so. (Dr) Rod Hudson

Friendly and competent firm...would reccomend.

Good service at a good price. Engineer was very pleasant.

Fantastic company! I have used them several times. Very professional and clearly care about the customer. Thank you

Accommodating staff, competent, punctual and good value compared to other companies. Would reccomend and would not hesitate to use this company again.

The team at GasWise did a great job of repairing a leaking cold water pipe under the bath in our property which had very awkward access. They were able to successfully reroute the pipework with minimal damage to the surrounding area, carefully avoiding our underfloor heating system and installed a new shutoff valve. I contacted them asking for assistance on short notice and they were able to book me in within 24hrs and sent 3 of their colleagues to work on the job together. They were all very friendly, took their shoes off at the door and cleaned up all mess before leaving. Overall really satisfied and will definitely be using them again when required, and would recommend to anyone looking for professional plumbing repair work. Thanks!

I woke this morning and going into the bathroom , I had a drip on my head, identified that the leak was from my boiler in the loft, I called looking for a plumber, and was initially told that they were fully booked until next week, but took my details in case anyone became free. Within 2 hours I received a call back from one of the engineers saying that should be able to come and look. 2 hours later Investigation and replacement part obtained and fitted. Most impressed with this service and would have no issues recommending them

had problems with finding a reliable plumbing company,but now i've found one,superb service from gaswise,thanks

Once again excellent service. Would like to say the unsung hero's are also the admin team specially Lucy. Excellent customer service skills and always goes out of her way to help. Thank you

Did a boiler service whilst also looking at my shower pump issue, rather than quote for a replacement pump, did a full review of the system and quoted the best solution (which actually is a pump replacement), despite more expensive ones being possible but not considered the correct solution due to our waterflow. What more do you want from a tradesman. Integrity, professionalism and does what they say they will do.

The owner of Gaswise ensured that I got a visit 24 hours after I had contacted him. The plumber who arrived was thorough,, efficient and couldn’t have been more helpful. The repair necessitated the removal of some wooden trim, which he reinstalled at the end of the job very neatly. I have nothing but good things to say about Gaswise.

Fantastic service. Work was carried out quickly and professionally. Engineer took his shoes off as soon as he was in the property without any prompt which made a welcome change from most other contractors coming in! Price was very reasonable. Would 100% use again.

This company are quite the scammers, lots of hidden costs or extortionate quotes for work that isn't really required. I booked them to come and check what work needed doing to my shower as there was a very slight leak, stated it was not urgent and they could come in a few weeks. Their employee confirmed the damp patch I said was on my wall was there and suggested what work needed doing to fix it. I then unexpectantly received an invoice for £84! No work completed, the quote I received from them was thousands! I had 2 other plumbers come and check the shower with no charge and they suggested some silicone remover to fix the issue, not thousands of pounds worth of work with hidden costs. I have reported them to trading standards, please AVOID!!!

We had a leaking pipe and GasWise sent someone out promptly even though they were very busy. Problem identified and fixed in a very professional way. Great customer service, would highly recommend GasWise.

Polite, on time, good quality service and follow up was quick and very thorough. Everything was resolved, tested and left in top working order. Great service.

Excellent service.

Excellent service with a heating engineer who went the extra mile to get our boiler right.

Annual Gas boiler service carried out. The lads are always polite and respectful of your property, taking their shoes off at the front door. Lucy is always very helpful booking appointments around days and times to suit. 15% price increase on last year sadly

Absolutely amazing service, Ben the service engineer was respectful, professional and honest. I highly recommend GasWise to everyone.

Once again, quick response and repair - can't ask for more!

The dates arrived for us to have the gas boiler at our home in Bodicote serviced and for a part to be replaced. These were split into 2 visits. Both of the engineers arrived at the agreed time and worked conscientiously to complete the tasks as quickly as possible, to eliminate any inconvenience, and to a high standard. We were suitably impressed and valued their friendly and helpful approach. Bernard Goodchild

Gaswise were excellent the whole way through. They came to service our boiler and solve a leak problem. Our leak got worse so despite being a very busy company, one of the engineers came out on a Saturday to resolve our problem. Both engineers we encountered were very friendly and efficient and Lucy in the office is the same! Highly recommend!!

Efficient, reliable and responsive. Highly recommended.

We can highly recommend this company. Everyone we dealt with in the office or onsite was pleasant, helpful and competent. Gas Wise Boys! Good gang of guys Working hard every day Impressed have to say Did a good job Solved any prob Flushing with success It all passed the test Now sorted and cleaned We're living the dream! Thanks lads.

Gas wise were referred to us by a friend and we were not disappointed They are very professional ,punctual and their workmanship of the highest standard Their workmen are very polite ,tidy and a credit to the business We had some intensive upgrades fitted by them and they were very competitive on price Would highly recommend and we will continue to use them as ongoing maintenance

The engineer did a excellent job and invoice was far cheaper than I thought. Recommended.

Absolutely brilliant service, very responsive when our boiler stopped working. Particular thank you to Luke who was hugely professional, considerate and extremely thorough installing the boiler. Everyone we dealt with at this company has been very efficient and friendly, an absolute pleasure, couldn't recommend Gaswise highly enough.

Boiler service. Excellent explanations from the engineer about the boiler and the future of natural gas boilers! I learnt a lot! Quick to get an appointment (less than 24 hrs).

Absolutely first class service and work by the team at Gaswise. the quality of work was some of the best I've seen. Great team!

Darren is a very competent and friendly young man. Nothing is ever too much for him. He always gives service with a big smile.

Thank you for your responsiveness and fantastic professionalism and customer service. Luke and Harry dealt with the leak from our hot water cylinder and Luke worked non-stop for two and a half days to remove the old cyclinder and fit the new one. He worked from 8 until 6 each day without a break. Luke has excellent customer skills and he did a really fantastic job. Highly recommended!

Recommended by a friend. Prompt response to investigate the source of a leak and the cause found within half an hour! Staff were courteous, informative and professional. I will join in recommending GasWise.

Awesome service from estimate to job complete. Reliable, value for money, professional and quality assured

We used Gaswise for a new central heating system including all pipework, radiators & boiler. They also fitted a new shower for us. They were professional from quote until completion. Their employees arrived everyday on time and left everything tidy at the end of each day. The work was completed within the timescale promised and I have already recommended them to two other people. Would certainly use them again & we are very pleased with everything they did.

We had a gas safety check carried out as well. Excellent service and transparent on costs. would certainly recommend as very reliable and efficient!

I cannot praise GasWise enough we had them come in and put a whole new boiler and central heating system in.To say we are over the moon is an understatement these lads went above and beyond to make sure they delivered exactly what me and my wife wanted , they were that good we even then used them again to do some work for a shower .The lads were very polite and very professional and are an absolute credit to the company GasWise

GasWise employees were reliable, turned up on the day and time promised, were helpful and polite at all times and appear to have done a very good job installing our new boiler. However my wife would have appreciated being told in advance that the drilling through stonework for the pipe-runs would create a lot of dust. Dustsheets would have been helpful.

Our boiler unexpectedly broke down, and we were without hot water and have a little baby. GasWise were out to us next day in the early morning, and Matt who sorted our issue was absolutely brilliant and helpful. A very efficient, friendly service who I would recommend. Thank you guys!

The service provided by GasWise Plumbing & Heating Services (UK) Ltd was very prompt, well executed and reasonably charged. Staff were very pleasant and we will certainly use them again.

Very professional. On time and the engineer polite and wore a mask. Cost also i felt was very reasonable. Would recommend them. Xx

Really pleased with the customer service. Answered phone promptly, able to book appointment within next 2 days for a non-urgent servicing task. They even called me to see if they could come earlier. Clear quote of price. Very professional, helpful and thorough job.

Great initial customer service and professional, friendly engineer who did a quality and tidy job. Gas fire reconnection and service, and Landlord gas safety check. Would recommend and will use again. Thanks Gaswise!

Reliable, knowledgeable, professional and they don't overcharge.

These guys are so good at what they do. Polite, knowledgeable and on time. covid secure as well. I would highly recommend!

Amazing Service from initial phone call to the engineer that arrived within 20 minutes , Friendly helpful and sorted problem quickly and well. One of the best Trade experiences I have yet to encounter . Would use again . Was also great value .

Very easy to deal with. They answer the phone very quickly, very nice phone manner and sent someone out on a day that suited me Also very reasonable prices. I'll be using again for sure

Brilliant service, empathetic staff, highly recommended.

Delighted with service from Gaswise. Tom, the Gaswise Engineer, serviced our boiler yesterday. He arrived on time, was courteous, wore a mask and took off his shoes before coming in. I had some questions about the use of the boiler - Tom was very knowledegable and took time to explain. Thank you Gaswise (and particularly Tom) for excellent service.

We had GasWise in to service our boiler and do additional work to our existing gas/water pipes & radiators. Paul came in to provide a well priced quotation and Tom completed the work to an excellent standard. Tom was extremely considerate towards our home and highly professional. We would recommend the company without hesitation.

Boiler service - Excellent, professional service. Highly recommend

It is always difficult to find trades that you can trust and value your business but I have always found that Jonathan and his team have supported us with quality work in our hour of need!

Gaswise recently fitted our Hive Home Heating System and Serviced our boiler and we could not fault the service he provided us. Lewis was friendly, professional and knowledgeable and was able to answer all our questions and completed our installation hassle free giving us a full explanation of the best ways to utilise it. We have always used Gas Wise for any boiler/heating work since moving into our home 3 years ago and will continue to use them in the future!

Great service. Friendly and always explains everything thoroughly. Highly recommended 10/10 👍🏻
