John Williams Heating Services Ltd

Excellent service from friendly, well qualified engineers

I emailed John Williams on Saturday, had a telephone call when the business opened on Monday morning, extremely efficient lady. Appointment made for Thursday. Too good to be true…..and low & behold a uniformed engineer turned up on time. He was courteous and knowledgeable, his young apprentice was just as pleasant Boiler serviced, lots of tips about setting timers, radiators checked. I couldn’t be happier. Finally a company that is efficient.

We,ve had various jobs, from replacing our hot water tank and removing the tanks in the loft.,moving o a pressurised system including heating. Shower tray waste, and first fit pipe adjustment in our bathroom. We have found John Williams Heating Services to be very helpful, when dealing with the Service Admin Team, and all the installers are always polite,courteous and take pride in their work. We're so glad to have used such a good local,and reliable company.

I have been clients with John Williams for more than 10 years. After some bad experiences with gas service providers when I moved from London to Wiltshire, I came across this family ran excellent company. John Williams was responsible for not only rectifying the careless jobs carried out by other contractors, as well as advising and installing the most efficient energy consuming ways of keeping my old Edwardian home warm through winter. My experience with the company’s expert engineers was second to none. Extremely polite and tidy, they always executed their job to perfection. I was a member of their Care Plan which made my life so much less stressful as I didn’t have to worry about finding someone to service my boiler every year. For these reasons and more, I wouldn’t hesitate to recommend John Williams to any one interested in an expert gas services providers.

Absolutely brilliant team and so organised and professional. Ellie and Georgina were knowledgeable and a pleasure to talk to and sent their team to help with a tricky job. All done in good time, well priced and lots of communication. They are coming back to service the boiler and no doubt will be another well managed job. Highly recommend this company.

Excellent service from the owners, technicians and administrative staff. Fully recommend this company

Highly professional friendly service. Arrived on time, explained issues very clearly. Clean and tidy work. Highly recommended!

So 8 years ago today the team at John Williams started work on our bathroom transforming into what I consider the best room in our house. I really can’t recommend their services highly enough. We also had a new combi boiler fitted the week before. And even 8 years on when we have an annual service by British Gas they always comment on the superb workmanship of the installation. We’re thinking of moving soon and John Williams Heating service will definitely be receiving a call from us soon.

reliable, friendly, competent and professional service - thank you

I have been using this Heating company for many years. They installed my gas central heating system 4 year's ago but used them many years before to service my central heating system.. I have always been very satisfied with with their work and the efficiency of their services. Their cost's are very reasonable and you get very good value for money.

Brilliant 👏

Had a new boiler installed and relocated along with some other minor jobs. The team was professional, friendly and did a great job. They also left everywhere very clean, tidy and hoovered. I'd definitely use them again and would recommend them.

Just had our regular boiler service and the engineer was punctual, informative and courteous.

Impeccable service from the JWH team - the gentlemen we had come to our house were very polite and did a fantastic job at installing our new Halcyan system. From the first call to the team in the office the communication has been fantastic. Faultless service. Thank you

After being messed around by various various plumbing companies, I found John Williams and spoke to a charming lady about my stuck bathroom plug who said, no problem, someone will be there by lunchtime and they were and they had brought two plug options for me to choose from and it was sorted in no time and works beautifully. There was no demand for card details prior to the visit and the amount charged was much more reasonable than the previous quotes from other companies and it was all in a very happy experience! I can highly recommend them..

Annual boiler service carried out. Arrived on time. Identified problem with gas supply being low pressure that was resolved by gas supplier. Boiler service completed. Professional throughout. Admin staff also good. Will have them back next year. Cost £102 inc vat

Great service. From the moment I spoke to the team in the office to seeing the engineer. You were recommended by a neighbour and I will definitely use your team in the future for my boiler service. Thank you all so much

I would highly recommend this company. Came out to us within an hour of calling them. Work complete was of very high standard. Both office staff and engineer, very friendly and helpful.

Fantastic service and very helpful/knowledgeable engineers. The admin team were also very helpful. Would highly recommend.

We used John Williams Heating Services Ltd to supply and fit a new boiler after our old one packed up and was condemned. The engineers did a brilliant job over two days and were very professional, friendly and knowledgeable. They took time to check the whole system was fully working and explained the new controls and cleaned up before they left. We would not hesitate to recommend this company.

A quick service and the company new about underfloor heating definitely to be recommended!!

Did a very neat oil fired boiler installation for my mother. Very polite and professional installers. When a problem came up they were open and honest about it and arranged to sort it out straight away.

Excellent service from the office team and the engineers would highly recommend regards Ben freeman

Efficient, swift and friendly they run affordable maintenance schemes and have knowledgeable and personable engineering staff.

Fabulous people. The best company around here!!!!

Had new heating system installed and am delighted with workmanship.

Did a good job of sorting out my bathroom pump. Polite and thorough. Very pleased. The price may be slightly more than some quoted but they are reliable and you can trust the work will be done correctly. A good job done.

I can't fault the service from John Williams! I would 100% recommend.

John Williams Heating Services have been looking after our boiler and heating system for the last five years. The customer service is always great – nothing is too much trouble. The engineers are all courteous, knowledgeable, tidy and efficient workers. They have recently installed a new Worcester Bosch boiler and replacement radiator for us and did an excellent job.

Amazing service. We have have the business for years but today was over and above what I expected. We discovered a leak in the ceiling, within a couple of hours Alex was here, investigated and fixed the leak with a thorough and tidy approach. He was also very considerate as we were working at home and on calls. 5 stars is not enough :).

From first speaking with the office staff to the completion of the work by several engineers I was impressed by their professional and friendly approach to their work and the excellent job they carried out.

A big thank you to the fantastic folks at JW for our new bathroom. From planning and choosing to fitting and finishing the team have been superstars. Always respectful of your home, making every effort to cause the minimum of disturbance, and leaving the house in excellent condition at the end of each day, the guys worked tirelessly to pull off an awesome job. Can’t thank everyone enough for another great piece of work.

Alex went above and beyond in his customer service ensuring that the moved washing was replaced and stable

Good, honest service and the lads who come to do the work are always friendly, hardworking and helpful

Very disappointed- genuinely hope others have a better experience than me. Was recommended boiler services from them which has cost me over £520 so far in the last 12 months. Within a month of the extended annual service, a part was leaking. When the part was repaired, another has been damaged. Contacted John Williams but they claim them both to be coincidences. Now been quoted another £170 to replace the part, and hope they don't break another in the process. I have no idea when this would end- sad thing is the boiler was perfectly working prior to all this 'maintenance' work. Feel like a lot of money wasted which is hard in this economic situation.

Too expensive. Taking 90 pounds for not fixing anything is not alright.

Excellent work - really helpful engineer. Arrived on time. Talked me through problems and what he was doing. Good advice, clear instructions. Left the place nice and tidy. Great value.

Alex was excellent - keen, helpful, friendly, informative and methodical.

Clearly pride themselves on good customer service! Have dealt with them twice and both times have been straight forward and efficient.

Very professional and courteous company. I am a long way away and had to rely on them letting themselves in and out of the property. They have always carried out their work to a high standard over the years with an honest and trustworthy service

New customer...did a great job getting my heating working again...will def use again

I've used JWHS for boiler servicing for a few years now. I contacted them with a boiler fault (no heating or hot water) and they were able to attend and resolve within 2 hours of my call - exceptional service. Thank you to the entire team!

Recently had Joshua round to complete a boiler service, he arrived within the given time slot and cracked straight on, explained to me about the service book etc. which was very helpful. Left the area clean and tidy. Will definitely use again in future!

Just had a new w/c and basin fitted. Excellent from start to finish. Very tidy job from a local reputable, longstanding company. Highly recommended 👌

Martin serviced our rather elderly Aga and gave us extensive information and advice on keeping it running at its best. We have used this company for many years and always found them very Genuine, honest people to deal with.

I have been a dedicated customer of John Williams Heating for nearly a decade, and during this time, they have consistently exceeded my expectations. Their exceptional level of service, attention to detail, and professionalism are what set them apart from other companies in the industry. From the moment you book an appointment, you are met with a smooth and well-organized process. Their office staff is friendly, efficient, and quick to accommodate any scheduling needs. The communication is top-notch; I always receive a confirmation of my booking, and on the day of the service, the engineer gave me a courtesy call to let me know he was on his way, which is always helpful for time management. During my most recent experience, the engineer was thorough in diagnosing the issue with my heating system. Unfortunately, it turned out that an expensive part would be required to resolve the problem. Rather than pushing me toward an immediate repair, the engineer provided a thoughtful recommendation to consider Worcester’s one-off repair service, given the cost and complexity of the parts involved. His honesty and transparency were greatly appreciated—it’s rare to find such integrity in service professionals today. After weighing my options, I ultimately decided to invest in a new boiler, and I’m so glad I did. John Williams Heating’s installation team was nothing short of exemplary. They arrived on time, worked with impressive efficiency, and maintained an incredibly tidy work environment throughout the process. Their attention to cleanliness and respect for my home was remarkable, leaving no trace of their work aside from the perfectly installed new boiler. What has always impressed me, and continues to do so, is the consistency of their service over the years. It’s not just about fixing a problem; it’s about the trust and confidence they inspire. I have recommended John Williams Heating to numerous friends and family members, and the feedback has always been overwhelmingly positive. Everyone I’ve referred has shared similarly glowing experiences, praising the company for their reliability, professionalism, and customer-focused approach. In an industry where quality and customer service can often vary, John Williams Heating stands out as a beacon of excellence. Their commitment to providing honest advice, high-quality workmanship, and unparalleled service is second to none. I wholeheartedly recommend them to anyone in need of heating services and will continue to be a loyal customer for many years to come. Megan

Fantastic Service. I have used them on multiple occasions and the team are always very friendly and helpful. Would highly recommend.

Amazing service from start to finish. As a young home owner they explained everything to me. Will happily use them again and recommend to anyone needing their boiler serviced.

We have been with John Williams for the last 8 years. Last winter we had a heating problem which resulted in our boiler locking out. Despite many visits they couldn’t sort the issue and we had no heating over Christmas. Their engineers changed the pump and motor which didn’t fix the issue. I lost count of how many visits we had by three different engineers. One of the apprentices managed to cross thread the screws on the motor which resulted in it not being changed at that time. When we eventually had it changed they charged over the quote due to the bodge job with the screws. We thought this issue was complete and we had agreed to continue using them despite the issues in the past as they did eventually fix it, when out of the blue they sent us a bill for over £300. We agreed there were some outstanding amounts after checking but when challenged on the labour they would not shift. The first hour on call out is more expensive than follow up hours which is fine but when they were called out to resolve an issue they couldn’t fix I think this is unfair and unjustified. I need some more work done now but I will not use John Williams again and I have switched to a competitor. A very disorganised company we will not use again.

What a fantastic service from John Williams, they completed a repair on an old tap , they were knowledgeable and gave good advice . Most importantly they arrived promptly and were polite, clean and efficient. I will definitely use them again and thoroughly recommend them.

Very pleased with the service I have received. Response is always prompt. I’ve used the company for a number of years and I’ve never had any issues with the work done. The engineers are always friendly, polite and knowledgeable. I have no hesitation in recommending John Williams Heating Services

Fantastic service! I wanted to replace an ageing heating controller / thermostat with a new Hive controller / thermostat and I didn't feel able to install it myself so I searched locally to me and found John Williams Heating Services, I spoke with Ellie on the phone and she quickly dealt with my enquiry and an appointment was set up in no time. The Engineer, Jake, arrived in the morning of the installation day, he was chatty, professional and really efficient and the invoice was very reasonable as well. A really good example of a very well run business, I was would have absolutely no qualms in recommending them to anybody needing Heating Services!

Professional and reliable service. The team were very knowledgeable and fully explained how to use our new combi boiler. Would use again.

New boiler installed quickly and efficiently, all checked and tested. Everything left clean and tidy. Excellent service, would recommend this company.

Boiler part ordered and supplied within 5 days of contact. Pleased to say heating now working perfectly and your engineer, Jake was very pleasant, efficient and informative.

Phoned asking for a quote and unless you are able to diagnose the precise problem yourself they want to charge you a call out fee to provide a quote

Had my oil boiler serviced. Team was fast, clean and had good communication. Engineer was really polite and professional. Pricing is competitive. Highly recommend.

Brilliant job fitting new heated towel rails. Also gave excellent honest advice on a plumbing issue… thank you 😁👍

Thank you so much Adrian was brilliant, and I’m delighted the problem I’ve had for months was resolved in the same week! Outstanding service!

Great job done as usual with servicing my boiler! Quick and easy to book the annual service, and the work was done professionally and courteously by a friendly engineer. All this is an increasing rarity these days so I would highly recommend John Williams Heating Services!

Really happy with the boiler service that we had carried out. Engineer was within the timeframe given and he was very friendly. Thank you for doing a great job!

A John Williams Plumbing engineer came to our house today to remove a water softener. Before the job was started, I requested that, on completion, the engineer leave everything behind which would be needed to sell on the appliance, specifically asking that he leave the length of copper pipe. The job was completed and the engineer left. Shortly after, we noticed that the copper pipe was gone. I rang the office to explain the situation, suggesting that the colleague who lives locally could possibly return the copper pipe on his way home. I have just received an email from John Williams saying that they do not recommend re-using the copper pipe. The engineer did not tell us this when we asked that the pipe be left. However, the email continued, we can have it back but we will also be given back all of the waste generated by the job!!!!! Needless to say we find this outrageous and can't believe the complete lack of customer service. We will never use them again and will certainly not be recommending them to friends and neighbours.

Thanks guys for helping us out John and his office team were great came and look at the problems straight away so thankyou . Jack who did the work is a credit to your company,knowledgeable polite and a really nice guy nothing was to much trouble . So thankyou all again for helping us out

Always a quick response and a very friendly team, excellent work.

Great service and support.

Used them to service a boiler. Paid £100, next day its broken. Quoted 2 weeks for a replacement. Thankfully found an accredited WB installer who replaced within 48 hrs. Obviously they are busy probably for good reasons but taking money for boiler service that breaks the boiler and then leaving you without hot water for weeks is pretty poor service to me.

Had our boiler serviced and received excellent help and advice. Use John Williams every year and have always been impressed with their honest service and reasonable prices.

John Williams Heating Service have undertaken my plumbing and heating maintenance repairs for a number of years. They are very professional and friendly from the first point of contact in the office through to the engineer visit. All work is carried out to a high standard, I would highly recommend!

I cannot praise these guys enough. They were fabulous and the best thing is they answer the phone, you can make an appointment and they actually turn up on time. Those are the qualities the average homeowners wants. Thank you to Joe, Dan (and apprentice) for your friendly and professional work and advice.

Great!

Excellent service. Dependable, clean and informative.

Excellent service, good value, professional and friendly. Highly recommended.

Highly recommend this team. Awesome service everytime. Thanks 😊

The best!!!

John Williams Heating Services have just installed a new boiler for me and I am very happy with their service. 5 star all the way. thank you so much for a stress free experience, I would thoroughly recommend.

Excellent and lovely to deal with as always.

Great company to deal with,super responsive, great communication,great product W/Bosch 8000i combi boiler at a very competitive price. Cleaned everywhere on completion.First time of using this company and it wont be the last if needed.When calling you might be lucky and speake to the lovely and informative Kerry who will direct you to the owner John.

A service was booked with this company 6 to 8 weeks ago. They rang 3 days before the service date and said we can't do it till the middle of January now and seem to think that was ok because you can't have the boiler on for the service. Do elderly people have to suffer and sit in the cold in January, they then went on to blame the coronavirus because 3 of their engineers are on 14 days isolation. Poor virus gets blamed for everything. Funny I don't believe them. So be careful using this company as a last resort. After posting this review suddenly Debbie Willliams Company Director starts phoning and e mailing me about my review. But I stand by it.

A small family run business, who give a fabulous customer experience

This company are always professional, polite and punctual. The engineers are thorough and always considerate. I would highly recommend them.

Top job, top team👍

The AGA went out last week and for anybody with only one cooking appliance this is not ideal. Phoned John Williams to make an appointment for an engineer and they said they had one local who could be with me in an hour. He came when they said got the job done and is a credit to the company. Very good service.

Waited 2 days for an engineer to arrive, then paid premium rates for the repairs so poor value for money. Would probably get better value elsewhere!

I just had a new combi boiler installed and Repositioned to upstairs airing cupboard. Chris and his young apprentice were absolutely amazing. You would honestly not even know they’ve been in my house! So clean and tidy and went over and above my expectations. Can not praise them highly enough. Also John William came out to quote and quote emailed within hours and appointment to fit at my convenience arranged swiftly. All my emails and concerns answered within the hour. EXCELLENT service from start to finish!

Great service and excellent team. Always willing to help. Would highly recommend.

I had a new boiler and oil tank installed. The team worked incredibly hard. The lead engineer was very conscientious and knowledgeable and made sure that we understood what he was doing and explained the job as it progressed. I was also very impressed with other members of your team who arrived to help out. It was lovely so see the team pulling together and helping each other. We were also impressed with the after sales service, both the office staff and engineers who have been reassuring.

Signed up to their boiler service program to spread payments of maintaining my boiler. I have to say, it's a pleasure whenever I have to deal with them and the engineers we have had round are very friendly and professional - super service!

After struggling with an awful Grant boiler for 10 years, we finally took John Williams Heating advice and had a Worcester boiler installed. The JW team did a great job of the supply and installation and we were up and running on the same day including a our new Nest thermostat. Our house has never been so warm and I haven't had to touch the boiler once since installation. Highly recommended!

I have been in the building industry for 35 years. Never in my vast experience have I come across nicer, professional office teams and heating engineers at extremely affordable prices. John you really have a great team. Three days, start to finish to install a new combi boiler the opposite side of the house to the old one. Brilliant. Thanks everyone. Rob and Jenny
