Garry and his team were absolutely amazing with advice and professionalism whilst our new boiler was being fitted - can't fault them and would recommend them highly

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.

Rosie Green October 31, 2025

Garry and the team are always professional, prompt, helpful and their work is of a high standard every time their services have been required by us. As a family we have blue flame policies for our properties. We could not recommend blue flame highly enough. Thank you all.

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.

New boiler & radiators

Gary responded quickly to my initial enquiry and gave good advice on what was needed. The work was carried out on the agreed date and everything is working perfectly. Would recommend Blue Flame

Sharon October 13, 2025

Boiler installation without all the fuss!

Gary was great throughout. As a local firm it was easier to get personal recommendations from family and friends who have also used Gary. From the initial visit to price up for the job which was a new boiler in the loft to the end when he personally visited to check all was good and we were happy. The quote was detailed and he had a date for the job which he kept to (unlike some others). Sol who did the work was fantastic, he just got on with the job. No fuss no mess and very neat job. Lovely bloke, Price was good too! All in all a very easy from start to finish and a lovely new boiler just in time for winter. HIGHLY RECOMMENDED! Thanks Gary and Sol

Blue Flame Gas Solutions. Excellent Service Providers.

Blue Flame carried out a recent boiler installation at my home. Their work was exemplary from start to finish. Garry acted quickly to provide a fair and detailed quotation for the work and Sol installed the boiler with skill. One small problem with a Hive hub was rapidly remedied.

What Heating Problems Can Your Engineers Fix?

We also carry out TRV installations, filter installations, system balancing, and full heating system improvements to help your home heat faster and run more efficiently.

How Do I Know If My Heating System Needs a Powerflush?

Signs include cold spots on radiators, slow heat-up times, boiler noise, repeated pressure loss, or dirty water when bleeding radiators.

Our engineers test the system flow, temperature drop, and water quality to confirm whether a powerflush or chemical clean is needed.
