Karen May 1, 2026

With my old boiler playing up regularly we decided to get a new boiler. We went with Blue Flame as they are local and we had used them previously and were impressed with how swift and professional they were. Everything about the process was easy. Garry came and gave us a quote talking us through everything we needed to know. On the day Sol came and did the job, efficiently, quickly and kept everything clean and tidy, lovely guy. The whole process was smooth and easy from start to finish and being local they're not far away should we need them . Excellent service, would highly recommended.

Replacement boiler

Overall service prompt, reliable and competitive considering the works we had. After an initial consultation with a large well known heating engineering business, we were advised that we would need to invest in a significant amount of reconfiguration works as part of a replacement boiler fit out which we were struggling to comprehend. Blue Flame Gas Solutions were recommended to us for a second opinion and after the initial consultation we never looked back. Garry and the team were extremely knowledgeable with our existing system brand, were able to advise on the best replacement system that was fit for purpose and were able to clearly articulate the reasons why we didn’t need to invest unnecessary reconfiguration works in addition to the replacement boiler. Communication with the business was easy and we were fully kept up to date every step of the way. Back office arrangements are second to none for a small business. Installation with the engineering team was engaging and all workmanship was clean and tidy. We were provided with full instructions and a thorough handover of everything before leaving us. Even after installation when we had some technical issues with the wireless smart thermostat, the business were very accommodating and quick to respond with switching us over to a hard wired thermostat to resolve. Cannot fault this business if you’re looking for a local and efficient heating engineering business with competitive rates. We look forward to receiving the service package with Blue Flame Gas Solutions going forward.

Professional, competitive and efficient Combi replacement

Garry came out and gave a good quote 24 hours after filling in the web form following a complete boiler failure. He went above and beyond to fit a new install in within 48 hrs with John completing the not straightforward job in a day. Professional, competitive and efficient from start to finish - a true rarity in this day and age. Thanks to both of you.

Kayleigh Jenkins February 22, 2026

Had our boiler relocated and replaced a few weeks ago. Perfect job undertaken. Would highly recommend.

Lewis Palmer February 18, 2026

Blue flame are always helpful when we require any work done, always clean and tidy never any mess left behind, and very satisfied with any work carried out. Would highly recommend!

RONALD JAKEWAY January 29, 2026

This is how a gas engineer should be, John Street, was smack on time polite, clean, excellent job and explained things he was doing as he was doing them. Went above and beyond. We would recommend him and Blueflame to anyone and everyone.

Julie Jones December 5, 2025

Highly recommended

Very friendly and professional. We were shown how to use the boiler correctly instead of wasting gas and money. This was not shown to us when boiler was installed by another company. Would highly recommend to anyone looking for this service.

New Boiler installation

"Blueflame has handled our boiler servicing for years, and we recently had them install a new one. Garry clearly explained the work beforehand. Sol completed the installation efficiently and to a high standard, with minimal disruption. He even took the time to walk us through the new boiler's operation. We are delighted with the result and confidently recommend Blueflame's services."

DEBORAH HALLETT November 1, 2025

Excellent fitting of a new Gas boiler

Excellent fitting of a new Gas boiler, thoughtful engineer, clean and tidy in his work. Boiler works great. Messy pipework around old boiler rerouted so it looks neat. Estimate matched the cost of the boiler replacement. Garry explained how to use boiler to keep house warm and cosy at the least cost.

Jude Hay October 31, 2025

It would be a jolly sight easier to say what I didn't like to be honest.- because I really rate this company. Where do I begin? OK first off I am a pensioner so personal safety, honesty and integrity are essential to me and I have found nothing but sincere help and support throughout the processes involved in choosing installation and after care. I don't have oodles of money - no-one does these days so it was vital that someone who actually KNEW about the products was prepared to spend time explaining to an ignoramus like me which boiler was best suited to my needs. Then came installation - on time (perfectly ....and doesn't that make a change!!!). There were a few niggles - caused by a poor bodge job done by a previous owner and they sorted that out for me too thank heavens. One perfectly working boiler oh and instructions what to do if this that or the other happened......hmmm great service but I have a memory like a sieve these days......enter after care Now this is where the company goes waaaaaay beyond anything I have experienced before....Its almost like they asked every customer what they would really really want (heck I sound like a spice girl!) and then pulled that all together So you can either choose the old fashioned route pay for a service when you need one (and pray you can afford it when the time comes) OR you can opt for a CHOICE of service plans.... bronze, silver gold or platinum. I pay monthly so I can spread the costs, I know that they will come every year to service my boiler and I rest easy. And now for the best bit. I am useless when it comes to remembering instructions, especially something like if there is a code that appears telling me the pressure has dropped; so bless him Garry made and sent me a video on Whats App so if I need to I can refer back to it - genius .....that would have been a call out back in the day and lord knows what that would cost in today's climate. And now? Now I am trying to update some of the radiators in my house and Garry is going to send me some pics of ones he has...am I likely to choose them - you bet I am - if they are good enough for your installer then they are certainly going to be good enough for me. Oh and before I log off that one unique extra? I have never seen Garry or his team without a smile, they always have time to explain things and show you how something works....yes I might forget what they said but I never forget the exceptional service with a smile - well done - all kudos to you.

Boiler replacement & radiator work

I recently hired Blue Flame for a boiler replacement, and the entire experience far exceeded my expectations. From the first call, Garry was prompt and professional, providing a clear, fair quote that outlined every step of the project. On installation day, Sol arrived on time and fitted the new boiler with confidence and precision. While he was there, he also took care of several radiators—removing the old units, cleaning the pipework, and installing brand‑new, efficient radiators that heat each room evenly. Throughout the process, communication was transparent, the crew was courteous, and the workmanship was top‑notch. I’m thrilled with both the boiler and the upgraded radiators, and I would gladly recommend Blue Flame to anyone seeking reliable heating solutions.

Annual Boiler Service - Baxi Boiler

Garry from Blue Flame came to service my BAXI boiler which he and his team installed last year. As promised when the boiler was installed, this first service was free. As always, Garry and his team were efficient and friendly both when setting up the service appointment and conducting the service and all of my questions were answered. I can highly recommend Blue Flame

Customer in RCT

We had a boiler installed by this company 5 months ago and were very impressed by the professionalism of the company. We have recently had a problem with the programmer and the company responded very quickly and did everything they could to deal with this. All our dealings with Blue Flame have been first class and we cannot speak highly enough of all the staff. Would thoroughly recommend this company.

Peter Johnson

Our boiler broke down and previously called out another company who gave us wrong information and misdiagnosed our boiler. Gave Garry a call and he called out the next day and found the problem instantly..was initially quoted twice as much by the other guy but ended up paying half that by getting the work done with Garry. very professional and friendly guy. thanks very much.

Friendy & Efficient

Contacted Blue Flame Gas Solutions as we had no heating, Gary attended and explained everything and fixed the problem. Excellent service and we will be using Blue Flame Gas Solutions in the future.

Blue Flame Gas Solutions all the way!

Had a new condenser boiler fitted. Carl did a fantastic job. He was professional, polite and thorough. He made sure boiler and the new Hive control was working before he left. He left no mess, old boiler was taken away. Garry followed up with us next day to explain warranty etc. That is what I call excellent customer service! Would highly recommend Blue Flame Gas Solutions ltd. Fantastic price and amazing service.

Hello. I would like to say a massive, huge thank you to Sean and Allan who did a brilliant, way beyond the extra mile job at our place in CO4 today. They managed what was initially a very stressful situation incredibly well, and customer-centred. Thanks to them we can now laugh about it. many thanks again, Sean and Allan

Johny J Love

Im getting on a bit so for me while I expect (and got) brilliant installation service 6 years ago, its the maintenance and service thereafter that is equally important to me. Now like I said age is starting to take its toll - the eyesight isnt all it was and as for trying to remember anything remotely useful about what to do once i a blue moon (ie after a power cut or if I am going to reprogramme the thingy {see what I mean useless at the terminology!!}) Enter Garry. I have to say he is nothing short of amazing on customer service. Not only can he talk me through what to do on the phone usually, if I still have difficulty he sends me a video! Oh that might not sound much to some of you but to someone on a pension that saves me a call out charge. I pay my maintenance costs monthly which works out superbly for me because I am not faced with huge bills and what's more I had a choice of bronze silver gold or platinum service. Oh and I hate saying this (because I do love seeing him he is such a nice guy) but he really has thought of everything and I have NEVER seen him without a smile on his face and thats damned rare today. read less

Installation of a gas boiler

Excellent service from start to finish. Knowledgeable engineer, good initial advice in choosing the right installation. Excellent follow up. Installers were efficient, polite and well presented. The work was carried out in a clean and competent manner and met our expectations.

I had Louie out to fix a two year long problem with an air source heat pump. He was super thorough.. fixed the issue. Left no stone unturned. Would highly recommend him/blue flame to anyone.

Our updating of our gas boiler

The work carried out was a first class experience. Survey and quote delivered quickly and professionally. The cost was very reasonable. The date for the work to be done was agreed and adhered to. The work was done within the estimated timescale and very professionally. I would highly recommend this company with no reservations.

Customer in South Wales

Professional Excellent Job

I have had Garry To put in a new boiler
He has done boiler services for other family members.
He also fixed my Mum’s boiler, when a contractor sent out earlier by a big name company said that it couldn’t be fixed and left my vulnerable mother without heating for a few days. Thankfully she allowed me to call Garry who sorted it straight away. He also charged far less for fixing the boiler than the contractor did for just coming out.

Blueflame are a very good company and deserve the praise!!
