Our Reviews

I was recommended Warner for a dead heating and hot water issue by a couple of friends of mine, and thankfully I took their advice. Dealing with Warner was a really great experience, explaining in simple detail his thoughts and processes of what was required to quite a complicated issue with my hot water and underfloor heating system. His perseverance finally won, and he left with everything working again. He stuck to his quotation, even though he spent more time on this than he thought was required initially. I would wholeheartedly recommend Warner for all your plumbing and heating needs after my experience and will definitely use him again, even just for the annual boiler service.

Boiler installation 2 months ago - Warner was professional and explained what we needed to know in simple terms. Due to the property being really quite old, the job ended up being more involved than initially expected. Warner took this extra work on with no fuss - it is clear that he takes pride in his work. Always cheerful and trustworthy.

Warner carried out a boiler service for us. He was prompt, polite, good value and as far as I can tell carried out a professional job. I hope to use his services again. Thank you Warner.

Thermoplumb have recently installed a new combi-boiler for me and the service went above and beyond what I had asked for. Instead of 1, I received 3 estimates providing me with short and long term options taking into account my current issues with water pressure as well as the predicted changes to the gas supply. The options included relocating the boiler to the attic involving minimal changes to the gas supply. The work was carried out in a timely and professional manner improving old pipes and keeping me informed throughout. No additional charges were incurred and my hot water pressure is amazing. I have used Thermoplumb on a number of occasions and always found the work to be top quality and value for money. I would recommend Thermoplumb to anyone.

I highly recommend Thermoplumb, amazing work from start to finish. Replacing my old boiler was not easy, but Warner was very thorough and did a fantastic job.



Thermoplumb did a combi conversion at my flat last year. I was extremely happy with all their work. Almost a year on and everything is running smoothly. They have a very high level of craftmanship, professionalism and effortless communication. They clearly planned out the work and discussed every step of progress with me. What set themselves apart from others is that they take a lot of pride in their work, ensuring the best service is provided and everything is installed safely. I was impressed by how knowledgeable they were including up-to-date details of any changes in the market. I wanted the newer boiler which is Hydrogen fuel ready for future proofing. Also, a connection via OpenTherm to a Nest smart thermostat which will be controlled by my phone. I found large companies like British Gas could not provide this, but Thermoplumb had the skills and expertise to install exactly what I wanted. Not only did they complete all the work well, they also resolved radiators issues and managed to overcome strict rules in my flat around flues and condensate disposal. I highly recommended them! You will have peace of mind going for a quality service.



Thermoplumb installed a new boiler for us in autumn 2021 and we are really happy with the service from them. Great job. Highly recommended. Gavin



Very happy with the new Intergas boiler installed by Thermoplumb. Warner's work is of a very high standard, no detail is missed and he clearly cares that his work is nothing less than perfect. He is professional, friendly, punctual, clean & tidy, and charges fairly. He called after the installation to check that everything was working as expected and that I’d received the Gas Safe and warranty docs. Excellent service!

We have just had our first annual boiler service done on our Worcester combi boiler that was installed a year ago by ThermoPlumb. The initial installation last year was done efficiently and cleanly with beautiful attention to detail, ensuring we had a top rated efficient boiler that suited our lifestyle with minimum fuss. All registrations etc. were done promptly to ensure our new boiler conformed to legal standards and the warranty was in place properly. As agreed, we were reminded when the service was due, to maintain the warranty. The service was thorough (compared to the British Gas service contract we had on our old boiler) and we feel secure with the boiler for the year to come. Professional and friendly service all the way.
