The Boiler Installation Specialists Ltd

We found The Boiler Installation Specialists through Checkatrade (or a similar site) and chose them to install our new boiler two years ago. They returned 12 months later to carry out its first annual service, and everything was completed professionally. Now, two years on, we're having our bathroom renovated by a different company. During the work, they encountered an issue involving the boiler that wasn't related to the original installation. On the off chance, I gave The Boiler Installation Specialists a call. They answered straight away and were more than happy to speak directly with my bathroom fitter, explaining how the boiler worked and helping them resolve the issue. We're also in the process of arranging for them to install new radiators, and the service has been excellent once again. From the initial boiler installation and annual servicing to their outstanding customer support and competitive quote for the radiators, I genuinely can't recommend this company highly enough. It's reassuring to have found a business we can completely trust, and they'll certainly be our first choice for any future heating work.

Really helpful

Very professional company to deal with, great service through out would definitely recommend

We needed to replace our ageing boiler, and had a leak in the coil in our hot water cylinder. Having never had a boiler done before, I didn't know who to ask to do it. My local plumber recommended this company and I am so glad he did. The communication was fantastic throughout, we had a video call to look at our existing setup, I received great advice about the new boiler and radiators etc. We had a visit from Chris before the job was done to have a look and talk us through it and then a few days later, the work was started. The chaps who came were lovely and efficient and very tidy. We are very pleased with the work they have done and so pleased to finally have central heating. They spotted a couple of other issues in our pipe work and fixed them which was excellent service too!. If you are thinking of having a new boiler done, I would definitely recommend this company. Thanks chaps!

I do not usually write reviews even though I find them very useful, but in the last week I have felt the need to write a bad one and a good. My hope is someone finds them useful. My boiler packed up recently and of course panic set in. Bad timing or what. Long story short. I advertised the job on a site where you can check a trade. Only 1 trade accepted the job, so I chose them. A few hundred pounds later, my boiler was still not working. To their credit, I was warned that might be the case. I decided to look elsewhere and contacted The Boiler Installation Specialists. I spoke to Chis, who was very helpful. No hard sell. While speaking to him I also realised that the company that tried to fix my boiler beforehand, charged a lot more than most. But Chris did say that it might have been because of their rate for the job. Thanks to The Boiler Installation Specialists, I now have a brand-new boiler that also includes HIVE heating and hot water smart thermostat. I just want to say thanks to Chris and the 2 guys that did the work. Apologies I do not remember their names. I have no hesitation in recommending them.

Simply the best , on initial contact any new boiler worries were desolved through to quote and installation it couldn’t have gone any smoother for us , the team did exactly what they advertise , friendly & efficient 100% recommendation from us !

They fitted my boiler in June 24 and no complaints, but they said I would need it serviced annually. This year when it was due I sent four emails and 3 of them were ignored. Eventually after two months I called them, and was given a date the following week - great! The night before i got a call, couldn’t make it, rearranged to the following Friday. Had already arranged to be home for the first appointment. The night before the rearranged appointment, a text message, can they move to Monday. had to decline as i will not be around. No response. Messaged the Friday morning to ask if they were attending - ignored. Not heard anything since. Extremely disappointing service

I throughly recommend the Boiler Installation Specialists LTD for their outstanding service and professionalism. From start to finish, their team demonstrated exceptional efficiency and attention to detail. Every aspect of the installation was carried out with precision and care, ensuring seamless and high-quality result. Their communication throughout the process was excellent-clear, timely and informative, which made the entire experience stress-free. They were also incredibly flexible, accommodating changes and scheduling needs with ease and understanding. The quality of their work exceeded all expectations. It's clear they take pride in delivering top-tier service and lasting solutions. I wouldn't hesitate to use their services again and strongly recommend them to anyone in need of reliable expert boiler installation!

From the very first visit, Chris made the process of getting our new boiler installed and relocated completely stress-free. His communication and people skills were excellent – he explained the process clearly and made sure we knew exactly what to expect. Nina, working behind the scenes, was just as impressive – approachable, polite, and lightning-fast in responding to any queries or sorting out quotes. The installation team were an absolute credit to the company. The boys arrived punctually every day, worked with real professionalism and an incredible work ethic, and were both friendly and approachable throughout. They were completely reliable, kept me informed, and went above and beyond to make sure everything was done to the highest standard. Not only did they finish quicker than expected, but they left everything spotless afterwards – you wouldn’t have known any work had been done if not for the shiny new boiler! The quality of work was exceptional, the price was very reasonable, and the whole experience exceeded my expectations in every way. I would recommend this company over and over again without hesitation.

A very pleasant experience , from first contact to instalation. Pleasant guys came on the day, very professional and all done by that evening, that was for a replacement oil boiler and new flue throught the roof , a happy customer !

We always get multiple quotes for any big job in the house, so when we wanted to upgrade to a combi boiler we did the same. The Boiler Installation Specialists were the most friendly, knowledgeable, and quick to respond of anyone we spoke to, and their quoted price was also very reasonable, with no hidden fees or "we ran into an issue and need another £200" type situations. We thought we had a bit of a tricky job to move the boiler and run some extra pipes under floorboards, but they'd of course done loads of jobs like this and backed up their confidence by doing a brilliant installation - the pipework is very impressive, which sounds silly but it's all in straight lines and makes a load of copper quite nice to look at! The job was done over 2 days and the installation team always arrived at 8am on the dot, cleaned up after themselves, and were very polite. They also fitted a new bath shower mixer and it's nicer than any I'd found online and goes with the rest of our taps. I'd recommend these guys to everyone - just wish I knew a company like this for every other job in the house!

Really a positive service from start to finish. Prompt response when I dropped them a line, organised what we needed which was a replacement boiler. The team arrived and fitted the boiler - they tided up and left zero mess. They were all friendly and understanding as I also have two children and needed to sort them out. Full recommend this company. Just book them and get your boiler replaced. Husband happy, kids happy,.

Couldn't fault the company or the team. Fantastic job and very professional and friendly.

I wanted to wait a few months before posting as everyone posts immediately and I like to give feedback after some time to evaluate. Firstly. The company and its staff are professional and very experienced. They’re helpful and go beyond what anyone else offered as far as providing expert advise and support to make me aware of all the options and how it would/ wouldn’t be effective on my individual property. They were prompt, clean and tidy, and did exactly what they said. Having all the recognised certifications and a financial agreement option is great if you need one. A new oil boier fitted albeit much smaller, more powerful, efficient and eco friendly. Bespoke fitting of extraction funnel through utility room roof, again all fulfilled with compliance regulation . The aftercare and expertise in the new smart tech Hive was easily explained. Cannot rate these specialists enough and highly recommended their work. Thank you

Amazing service and excellent job done! Would thoroughly recommend without hesitation! I asked for a boiler quote, that evening I have a video call with Chris and had a quote on my inbox at 11pm that same night (you can’t get better than that). Having spoken to a few boiler companies, Chris was the first one to suggest a back vented boiler which was much tidier for the install location. We had a small wall to remove and an old Rayburn to remove, all other boiler companies wouldn’t do this making it difficult, it was no issue for Chris, he did it all the same day. On the day of the boiler install we had 4 plumbers in our house working hard and the whole job was done the same day so we didn’t have a night without heating, which was amazing! From start to finish nothing was too much trouble, excellent company. Will definitely use again!

We had a fantastic service from start to finish - it really is rare tofind such good service. Nina was so helpful and knowledgeable and very quickly provided us with a quote. We instructed and gave a date that worked for us and the guys came to do the installation The guys were all so lovely, and accommodating on the day, I would definitely recommend this company to my friends.

After outstanding customer service from both Nina and Chris we quickly proceeded with the quote provided to install a new boiler in our home. We had Jordan and Callum come to complete the works on installation day, both of which were extremely professional and respectful. All of the work was finished to a high standard and Jordan was extremely helpful with any questions/queries I had regarding the new system. I would highly recommend this company from my experience and am very happy I’ve found a local reliable plumbing firm. I will be using them for all future plumbing works including my annual boiler service. 10/10.

These guys are excellent. Had a new oil combi boiler installed, and my ancient regular boiler system removed. From the first call with Nina, who explained everything in detail, to the guys arriving to carry out the work, the whole experience has been great. Very polite, left no mess, excellent workmanship. We are really happy and would definitely recommend this company to anyone.

Had my boiler and radiators replaced today by The Boiler Installation Specialists, and I'm very pleased with the high standard of their work. Professional, friendly and easy to talk to; the whole team were happy to explain where I needed more clarity. I also found the information in the Knowledge section of their website, really helpful with interesting videos and recent charity work. The upgrade is a huge improvement and I'm so glad I found them. I'm very happy to recommend.Thank you, Nina, Chris, Mason, Jordan and Louis! Margaret

Spoke to Nina about our very old and now problematic CH....... Chris was round same day! Extremely knowledgeable and helpful BUT NOT at all pushy .....after the visit we had questions.....sorted out with a great phone chat.The result... 33year old system totally removed and replaced.... every single bit!.....in under 4 days.Great team skilled and tidy and a pleasure to have in your home.....thank you Jordan,Mason,Louis and Callum.New system superb and a job I was anxious about,all done. Recommended without hesitation, couldn't have picked better people.... many thanks Chris and Nina

Great job, great team and all carried out professionally and as promised. Would highly recommend.

I echo all the 5-star reviews this company has already received. They give 100% commitment to giving you the best possible service, a quality installation at an excellent price and amazing customer communication. I had questions I sent by email on a Sunday not expecting a reply until Monday, and I was flabbergasted to receive a reply almost straight away. They simply want to make a fan out of you and have thoroughly succeeded in our case. If you are reading this now, consider yourself lucky - you have already found the best people for your heating. You needn't bother shopping around anymore, just get their quote. Big thanks to Nina, Chris and the whole team!

Very impressive and efficient service from start to finish. Definitely a 5-star service!

What a wonderful company, I cannot recommend Chris & his professional team highly enough. Very efficient, hardworking, with great communication. Would highly recommend to everyone and will definitely use The Boiler Installation Specialists Ltd again for all our plumbing & heating needs.

Great service from start to finish. Firstly - Nina in the office offered a fast turn around for someone to come for a free quote and lucky someone was in the area so managed to get them round the same day. Any questions I had Nina was there to answer! And not to mention my quote was sent to me the same day and booked in shortly after. The men who worked on replacing and moving my boiler was amazing! Everything was kept clean and tidy, they was extremely polite and when explaining the job they made sure I fully understood everything - great communication! I will be using this company in the future and will be recommending as such a great service!

Lovely people, great knowledge, Amazing service and reasonable too V much recommended

Great service, were able to meet our requirements for a totally concealed tracpipe and went above and beyond when removing old pipework

We had our boiler fitted in November. Quick. Neat. Efficient. We stupidly ran out of oil and then got an air lock. We called the company today a Sunday and the phone was answered immediately. We got all the necessary support to solve the issue and we are back up and firing!! Excellent after care support!!!

Very fast efficient service ! Nina is absolutely fantastic at getting back to you and answering any queries always happy to help ! My boiler was fitted in a day which was rather impressive. Very happy with this company

These guys are absolutely brilliant. Quick, clean, friendly, thorough and efficient. I'm delighted with what hmthey did.

We are truly grateful for your excellent service this week. From no-nonsense advice to quote to installation, the whole process has been seamless, polite and professional. We are now enjoying a new boiler within days of making contact. This is in stark contrast to another firm who took weeks to conclude that our old boiler was beyond repair and needed another three weeks to install a new one. Can’t recommend highly enough. Thank you kindly 🙏🙏🙏

Excellent company from the moment I made the first call I felt at ease. Very knowledgeable and helpful.The installation was conducted in a very professional manner. It was clear to see the installers were very skilled and experienced. Also 10 out 10 for good housekeeping, cleaning up as they went a long. I have since recommended them to friends and family.

Exceptional service and great after sales follow up. Would highly recommend.

A huge 'Thank you' to The Boiler Installation Specialists Ltd. They were exceptionally proficient from initial enquiry to completion. They carried out work efficiently from Nina's communication skills to Jordon and Mason's on site work. Chris was brilliant at explaining all options and making suggestions. The crew were adaptable, courteous and tidy and explained everything post installation.

Excellent service and team work, my boiler died on Monday night, by the next Monday evening boiler was up and running again, so far the heating perfect. Chris was very thorough with his job and clean up after, Excellent service. Nina was brilliant she ensure l got the best deal, fantastic customer service.

Absolutely brilliant, explained whole process clearly and how long. Excellent price, all done to our requirements in two days. Very professional and work was to a high standard. Went above and beyond with help regarding other work, I highly recommend them.

I highly recommend The Boiler Installation Specialists. Very professional and knowledgeable in their field of work, had a new boiler installed and very happy with the outcome.

Would highly recommend! Professional & friendly & I received excellent value for money. They offer a seamless service from start to finish. The whole team were brilliant and I am extremely happy with my new heating system! Massive thank you to Chris, Nina and the team!

Absolutely outstanding service. Oil combi boiler pooped itself Wednesday night, contacted Thursday morning, immediate response , quick video assessments and a plan was in place by Friday morning. New boiler not only fitted but in a new location due to new regs by Saturday evening (grade 2 listed property) The service from this company is 1st class. Nina kept communication open alongside Chris all through the project. His 2 engineers arrived 08.15 Saturday morning and just cracked on with it. Chris arrived by midday and all done by 4.30 I can not recommend these people enough. Thanks guys Simply the best !

A fantastic friendly and personal company to do business with, from the people on the end of the phone to the lads that come round to do the job required. First rate job done. Arrived at the said time to start and worked through till it was completed, working clean and tidy throughout, very professional. All aspects of the job were explained in easy language to understand. Will definitely be using them again when required. HIGHLY RECOMMEND this company, very trustworthy.

Prompt, courteous, professional, quick, clean and great value! All round, couldn't have asked for better, from first contact to full boiler replacement. Everything was very smooth

Great customer care, very friendly, knowledgeable, nothing was too much trouble for Chris, Nina and the team. We first contacted them when our hot water cylinder started to leak, they prioritised us and fitted a new one quickly, which with little kids in the house was a god send. They also fitted a new boiler for us recently, offering lots of advice and guidance on what type and model would best suit our needs. We will definitely be contacting them for our annual boiler service in the future.

Very, very good company, put a new boiler in for me, Chris excellent at his job.Nina who is first port of call ,arranges everything, always kept me well informed.

We had The Boiler Installation Specialists come and replace our boiler for us earlier on this year after only 12 years of the previous boiler (which was about as long as they tend to last these days!). They were brilliant. We had a leak in the room above which had been going on for ages and another leak in the cupboard at the back of the room which was almost inaccessible but somehow they managed to fix everything and the cost stayed sensible, considering the amount of work involved. I cannot recommend Nina and Chris's business enough-not only are they lovely people to deal with but they do a first class job. Thanks so much guys!

Chris, Jordan and Mason all lovely guys, well trained, very competent and respectful. Did a great job on my boiler and heating installation. So glad I found them after the debacle with the previous engineer.

Excellent experience with this company - sensible, no obligation and accessible advice, which led to us opting for a new boiler. The team went above and beyond to fit in the work extremely quickly (very much appreciated since we were without heat and hot water), and we received professional workmanship from polite and very tidy, respectful workman. Would not hesitate to recommend - our house has never been so warm and cosy and we felt supported and well advised throughout the process.

Excellent service from start to finish

Amazing service, the whole process was seamless and Nina was amazing on phone anytime I need clarification on anything during the process. A1 5stars

Boiler failed Sunday and by Friday we had a new and far more efficient replacement fitted. Excellent communication from Nina - including out of hours replies. Very competitive price and swift, clean and tidy installation by Chris and the team. A fantastic company which I have no hesitation at all in recommending

Very highly recommended. Fantastic team, professional and friendly, and despite all my anxiety about my old house and potential problems, the team delivered a high quality, smooth and stress free installation of new boiler, cylinder and ancillaries. Could not recommend them more highly and will definitely continue to use for annual service etc.

Both Nina and Chris fitted in my 89 year old Mum for a boiler replacement into their already very busy schedule – inspecting and quoting late on a Sunday and installing on Wednesday. We were very grateful for the care and attention given to completing the work so well and with minimum disruption for Mum. Chris stayed until he was sure the system was working properly and everything was left clean and tidy. And the suggestion of the Hive controller was inspired. I will certainly know where to come should we have any further heating needs.

Great team. Excellent attitude with fair pricing. Highly competent work with expert knowledge. These specialists really live up to their name.

From our initial enquiry, to the site visit by Chris, to receiving the quote from Nina, the Boiler Installation Company have been great, very efficient, very knowledgeable, they provided a great service and the team of Jordan and Louis the installation guys who were second to none. Great communicator, very efficient, very helpful and very thoughtful young men and a credit to themselves and to the Boiler Installation company. Thank you all for the great service, the new boiler and the Hive controls which are great and the minor other modifications you did for us. Thanks again. Stephen and Elaine

This company is fantastic so helpful and knowledgable when it comes to oil boilers and tanks. Chris and Nina really went above and beyond with sorting out my boiler and tank , so professional.100% recommend .

Super installers, knowledgeable and hardworking, very good price. Did an excellent job and would recommend for any boiler installation.

Excellent service with great communication and highly experienced professionals. Thank you Chris and team for sorting out our boiler and radiators.

Fantastic experience with this company. From making first contact to installation of a new Grant external oil boiler took a week. Nina made the quote/ordering process very easy to understand, great communication. Then the installation team of Gordon and Mason were very professional, did a very neat job and explained everything very clearly. Would highly recommend.

Excellent service and knowledge! Finally a company who knows how to deal with the customers. Highly recommended!

The Boiler Installation Specialists have installed new boilers for me and most of my family now with each of us recommending them to the next. They are extremely professional and competent on the job as well as having the best customer service thanks to the lovely Nina. My grandparents had a gas leak recently and had to be shut off by Cadent. Nina answered my messages on a Sunday evening and had someone round first thing on Monday morning to help them. Despite the issue being nothing to do with their work (it was a problem with the meter) they went above and beyond to help them get it resolved through their gas supplier. We are very grateful to them for all they have done and wouldn’t hesitate to recommend them.

Thoroughly impressed with The Boiler Installation Specialists, Nina and the team have provided an outstanding service over the years and have even provided support during unsociable hours. I would wholeheartedly recommend this company to anyone in need of a new boiler!

Prompt, skillful and excellent service throughout – from initial quote to swift installation. No hesitation in endorsing their services.

Professional, reliable and friendly company, who deliver exactly ' what it says on the tin '. We would have no hesitation in recommending them to others.

Omg there are no words to describe how helpful Nina is , she bends over backwards to help! highly recommended and most definitely recommended! Most professional and extremely professional! I can’t recommend enough…. Thank you so much Nina 😀

Fast, Efficient and Expert. Great service from start to finish. Our oil boiler packed up in mid-December. They provided a quote (cheaper than an alternative quote we obtained), surveyed, and installed within a week. Very happy to recommend.

Installation very good. Follow up, forget it - calls and messages to the office go unanswered. Disappointing.

Great knowledgeable friendly company. Very happy with our new boiler and oil tank thank you

Was a pleasure having the work done. Clean tidy very professional Great service

After expertly installing my boiler they come annually for the service. Unable to fault them

If I can't do a boiler job for whatever reason, I'll always recommend Nina and Chris. Good customer service. John Ari Plumbing & Heating

Better late than never. I rang Nina on a Friday and Chris came the following day to survey the fitting of a new oil boiler. We had a 40 year old gravity feed coal boiler. Very inefficient. Chris was very thorough surveying the old system and explained how the new system will be installed. He is a very knowledgeable, professional person. I knew straight away he was the right person to install our new system after answering so many of my searching questions. We agreed on a date of installation and the team arrived and got down to work. All team members knew what their brief was and didn't waste any time and got on with their jobs. I was a little apprehensive how they were going to cope with replacing an old cast iron boiler with a very efficient new boiler but I needn't have worried. It was suppose to take Chris & the team three days but they completed installing, testing, balancing & tidying up the house in two days. What an achievement guys! I would, without any hesitation, recommend Specialist Boiler company for boiler installation. Thank you Chris and your team for a magnificent job. Ned Shah

Good quick service and friendly helpful staff

We moved into an old house where the heating system was in need of a full replacement due to the age of the house. Chris came over to give us a quote. He was very informative and we received the free quote a few days later. Nina was very helpful in the lead up to the start of the work to go through the quote a few times and do any amendments. The company (made of up Chris and 3 of his workmen, and Nina who handles all of the day to day admin) took just over 2 days to install a new heating system. The work included replacing most of our radiators (including some repiping), installing a new boiler and an unvented water cylinder, draining and flushing out the old system, installing a Hive thermostat, new thermo valves and lock shields on to the remaining radiators. The system at the end was balanced. Connor, Mason and Jordan arrived just before 08:00 to start the work and left around 17:00 on both days, and Chris came over to inspect the work on the first day and worked on the second day. All of them were very pleasant and took care to keep the house clean by putting covers down, and also cleaning up at the end of each day. I was not happy with the condition of two radiators (had dents on when unpacked) and they went out to get two new ones with no issues. I also asked questions to the workmen at various stages of the work (to educate myself on the new system) and they were happy to explain the various stage of the work. At the end, Chris went through the whole system with me and I asked a few further questions. We were very happy with the standard of the work and the heating system has since worked extremely well. I would recommend The Boiler Installation Specialists, due to the standard of the completed work and due to the nice nature of the small business and friendly staff.

A lot of thought and energy has gone into how this company delivers its service. They are superb because they work hard at being superb and it shows. Having engineers or builders in is usually a bruising encounter. Not this group: it was a pleasure and you have gotta ask why aren’t more firms like this one!

Would highly recommend using this company with the excellent customer service from Nina and her vast knowledge of oil boilers and recommendations for replacement. The installation also ran smoothly and successfully with the fitters turning up on time for an external fitting on a cold snowy morning. The only reason I could not give 5 stars was that the follow up paperwork proved hard to obtain and I had to chase up on quite a few occasions. Other than that, first class!

Quick response to initial email. Appointment made the following day for a quote and work commenced the following week. Nina was extremely helpful and followed up with phone calls to confirm everything went well. Chris & his team started at 8 & worked till 6 to complete the boiler installation then Jordan & the team returned to install the radiators. It’s a pity some other companies don’t have the same work ethic. This is a company that stands out & I would definitely recommend

Very pleased with the installation of our new boiler. Professional service was received.

Used them after receiving good reviews full boiler replacement plus updating all old pipe work amazing service on time every day left clean every night. Kept to quote went above there said quote but refused to charge me. Back up service brilliant. They deserve all the reviews they get. Brilliant boys Chris. Connor thanks

We were looking to replace an old 37 year old boiler. We came across this company and got a quote which was 1/2 the price of the local conpany we usually use for our plumbing and they could do the install the boiler the following week rather than the 6 week wait we had been quoted by the other company. The job was completed within a day and was done to a very professional standard. I would definitely recommend this company to everyone that needs a new boiler. 1st class service.

5 Star Company Chris and his team excellent service. Highly recommended. All done in one day no issues. Clean tidy and very professional. Many thanks to all the Team. Mr and Mrs Burns

Great company to deal with, very quick to come and survey the house, quote and then install the boiler. Very knowledgable people and great job done. I would highly recommend them to anyone.

This company is absolutely outstanding. Nina is so professional and helpful. She always responds to enquiries in a timely manner. Despite the complex level of work required to install our heating system in an old period property, the team were super efficient, treated our home with care and always cleaned up each day. We were also given a high level overview of the heating system and how to manage it. Our home is super cosy and warm now thanks to this wonderful team. We cannot thank you enough!

Very happy with new boiler installation completed on the coldest day of the year brrrr

5 star service - from initial quote to install. Installation of new boiler completed in one day by fitters to a high standard with no mess left behind. We are really pleased with the service we have received from The Boiler Installation Specialists Ltd. Chris, Jordan, Nina, they are reputable guys and reputable company. Excellent experience, I am a happy customer :-) Would definitely use again and confidently recommend.

Just had fitted a new Worcester Bosch oil combi heater.  From quote to installation, we received an excellent, timely service.  Our old internal wall mounted oil boiler was removed and the wall repaired and the pipes moved so they were hidden.  The new boiler was installed outside.  All the work was done in one day.  Would recommend them without reservation. Michael Taylor.

Really professional and friendly company. From Nina dealing with enquiries and Chris and Conner doing the install really pleased with the work done.

This company got us out of a jam after our boiler packed up in December last year. We phoned them on a Monday and as luck would have it they'd had a cancellation due to Covid. Chris and Connor came and started on the Thursday and by Friday we had a fully functioning oil combi boiler. Nina in the office is a very efficient, helpful and knowledgeable lady. Would highly recommend thus company.

Professional from start to finish. Easy to get hold of, quote given same day and all booked in. Guys turned up on time, worked hard all day to get everything done and to a high standard. They were at all times professional and courteous and explained everything I asked about. Paperwork sorted efficiently and boiler guaranteed for 10 years. Definitely recommended.

Very good and good price would recommend them to anyone that wants a plumber. Good service

great job. the boys were professional with their work, I would definitely recommend their service thanks,Naemat

Came out in a timely manner to complete install. Installation was performed in a professional manner and Nina was and still is just a phone call away and has been extremely helpful would highly recommend their services

I have no hesitation in giving TBISL 5 stars. High professional standards from start (getting a quote) to finish (a complicated job completed in a single day). Chris, Mason, Jordan and Connor were punctual, courteous, careful and a pleasure to have around - though they finished off most of the Hobnobs. Great job. Thanks!

Could not recommend this company enough. Initially Nina is super helpful to get the ball rolling, quote provided very quickly and cheaper than other local and bigger national energy companies. The boys that arrived (Jordan and Mason) were here for 2 days, got straight to work, were clean, tidy, polite, professional and conscientious of any noise or mess that may be created with little one running about. 40+ years old back boiler, redundant pipework and 3 water tanks removed with a new Worcester-Bosch Greenstar combi installed in the loft paired up with a Hive smart thermostat. Heating system was flushed through also. Very professional and no doubt I'll have them back for my yearly servicing. Thanks, 5*

The lads are competent enough and polite. The problem is Nina, the woman on the phone who you arrange an appointment with. She is passive aggressive, doesn't listen, talks over you and refuses to accept she's made errors. She should not be in a customer service role. If it wasn't for Nina I would return to this company for further jobs. Alas she puts me off with her bad attitude.

My old internal wall hung boiler stopped working on a Friday morning and by the next Monday evening a new external boiler had been installed by Chris and his very professional team. I cannot praise then too highly.

Phoned for a complete heating upgrade following my internet enquiry. Women was pushy and only offered a boiler without answering all the points and some how managed to give a price fully installed without doing a survey. Told her i was not interested and ended the call. She called back and became even more aggressive "sales technic" to which I instructed her to remove all my details under GDPR twice before she took note. I certainly wouldn't call them Specialists, more like "second had car sales men".

Chris and his team removed an old internal oil boiler and installed a new more efficient external Worcester Bosch one. They showed up bang on time, took all the old hardware away and cleaned up, made good the old flue hole, fitted the necessary new piping exactly where we wanted it and took us through how to program the new Hive system. I cannot fault TBIS - from the first email and call with Nina to Chris and the team leaving our property after the job was done it was professional, courteous and good value for the best equipment we could find. I would not hesitate to recommend them.

Wow, what can I say. This company are so professional and efficient. Ordered Monday, fitted by Friday...when you first phone and talk to Nina, she is so courteous, efficient and knowledgeable, it's unbelievable.....Chris and Connor came to fit our boiler...They were friendly, helpful, clean and tidy and also really professional, they couldn't do enough to help us.....Highly recommend, this company, and I'm really fussy who I use......Thanks guys.

Excellent service provided by this company, no complaints whatsoever. I had my boiler installed at the end of last year with them and they were able to do it at short notice when we were desperate. Nina was extremely helpful and resourceful from the very start - its refreshing to work with someone who is so proactive and with so much common sense! The installers were very friendly on the day and did everything within the timescales advised in advance. They did a great job and left everything clean. A very honest company and I would not hesitate to use them again.

My BIS on-site team was Chris lead engineer with Gordon and a younger chap, who replaced our aging oil boiler into our old house and integrated it with the separate water heater tank over two days. They were tidy, courteous, responsive and efficient in their work. More than this, they also solved a few issues with the existing radiators & plumbing for our convoluted set-up to the point that the previous misfunctioning system (only 30% effective) now is fully operational with all rooms betting a proper blast of heating. They truly went beyond the remit of boiler installation by thoroughly testing all the radiator performance issues and solving them until 6.45pm on day 2. Nina Warren in the quotes & finances side was brilliant too. We are very satisfied customers and can thoroughly recommend The Boiler Installation Specialists Limited company.

Fantastic service... All hours... New boiler and new water tank fitted... 🙏🏼

phoned on Saturday, agreed price, new boiler fitted on Monday, very helpful, would recommend them, from the lady on the phone to the two chaps for installed the new boiler, excellent service,, thank you.

These guys really do deserve all the plaudits they receive. They were quick, efficient, friendly and professional and they went the extra mile by affixing two big radiators into two bedrooms after I had works done. They also arranged a good finance deal with no upfront costs for year. Five stars!

Cannot recommend these guys highly enough. Absolutely brilliant and very caring company who go above and beyond for their customers. A huge thanks to Nina and the team for replacing my broken boiler so easy and worry free

The experience of having a combi boiler installed by this company has been excellent from the first phone call till the boiler installation was complete. Nina from customer services as well the guys who came to install the boiler on the day were really professional and did a fantastic job. The price quoted was probably the best among all the other companies I spoke to. The installation was completed well in time with minimal disruption to the apartmentand the guys left the apartment very neat. Thank you for providing excellent service!

Very professional and an excellent customer service - from the point of initial enquiry to the very end of the installation. Knowledgeable and helpful customer service advisor. Engineers did a clean job, were flexible with timeframes and attentive to our needs. Very reliable and did not let down like the previous engineer from another company did. Fair pricing. Highly recommended!

Installed a new oil boiler for me in MK43 and removed my old LPG system ! I can not recommend this firm enough... 10/10 keen price/quick service and great install

Helpful, polite, efficient and clean and tidy. Chris and his team fitted a new boiler and several radiators. They did an excellent job and I wouldn't hesitate to recommend them.

Good service, compeditive prices, polite helpful staff and they leave the home clean and tidy afterwards

Brilliant service 5 star care thank you for my new combi boiler just in time for winter ⭐️⭐️⭐️⭐️⭐️

Efficient, friendly & affordable service. Work immaculate.

Great Customer Service, competitive prices and job done very well. Very happy with the service we received, would definitely recommend 👍🏻

I had my new combi boiler fitted on 29th March 2019 by Jordan and Mason. They arrived early and completed the job in a very professional and efficient manner. They were both very courteous, polite young men. Jordan explained everything to me at the end of the job and they even hoovered before they left! A big thank you also to Chris and Nina who have also been very helpful and supportive throughout the process from purchase to finish. A lovely company to deal with and I would highly recommend them. Thank you. Angela Levitt.

When our boiler broke down, we had no idea how expensive it would be to replace it. I did a quick search online and came across The Boiler Specialists. Nina was ever so helpful and reassuring about the whole process updating me up until the fit out. The job was done perfectly with zero mess. The only negative comment i would have is that the panel was broken when fitting the new pipe, which was not replaced and left for us to replace at our own cost. Overall i am extremely happy with the service, and customer care that Nina in particular has provided.

Jordan, the installer was clinical with his Pipework and Nina at front desk was very helpful and made the purchasing process easy. Overall- Quality workmanship, excellent customer service. Well worthy of 5 stars!!!

It was very difficult finding local companies that could install 2 new replacement boilers with the complicated design we required. We had many companies around our house all suggesting different solutions however it was only The Boiler Installation Specialists who actually knew what they were talking about and the only company who could answer all of my very technical questions as I am a ex engineer. If you are looking for a specialists company use TBIS by far the best in their field and I understand why they are highly recommended and rated because they truly are a specialists firm. Many many thanks to Chris and Nina.

Had a new boiler fitted by TBIS today I would highly recommend them 1st class job ..very polite and very tidy from Nina in the office to the team who fitted the boiler thanks again now I'm looking forward to winter ..cheers

I recently had a combi boiler fitted with this company. From the initial contact with Nina through to completion everything ran smoothly and I was kept informed at all stages of how the works were progressing. The service was efficient and friendly and they went over and above to make sure the job was completed on time (early in fact) and also left everything clean and tidy. I would highly recommend this company.

I have just had a new boiler installed with the boiler instillation specialist. I can not rate them high enough!!! I never normally leave reviews but the service I received from them,a review the first thing I wanted to do! From the first phone call to Nina I have never felt so comfortable with a company. All my questions were answered the price was the best out of all 5 companies I called before proceeding with them. The boys on the job were a pleasure to have in my home. 5 star if I could rate higher I would !!! Definitely recommend!!!!

Excellent communication from the beginning to the end of the job. Chris came out quickly and there was regular contact with the office. The pump was fitted and values replaced quickly and efficiently with no mess or hassle for us. This is our second encounter with the company and on both occasions we have been very happy with the work completed! We would and have recommended this company, very professional at all times!
