Had lots issues with an old boiler and they were very quick to come out to check it and repair it each time it broke down, and when it finally conked out they managed to fit us a new one within 2 days. Also had all the radiators replaced and guys did a very good job

Firmusheat were working on a project close to my home. A few days ago, I encountered an elderly lady that required significant assistance to get home with too much shopping that was beyond her capabilities. On my own, I was struggling to cope. Fortunately, two of Firmusheat's employees (Lee & Connor) were passing, came to our assistance and we managed to get her home safely. They were most courteous and giving of their (work) time, which was very much appreciated. Great humanity chaps. Thanks a lot.

Steve and his team were very professional. From the beginning the quote was very quick and competitive. Originally my old boiler was in my garage which was causing problems this was solved when Steve suggested relocating the boiler to our bathroom. The work was completed within a week of me accepting the quote.

This is a very professional and well-organised heating and plumbing business. They undertook a complete re-plumb of my property in South Kensington, including the installation of a new boiler, underfloor heating, hot water cylinder, and all new plumbing into 4 bathrooms and a kitchen. Since then they have returned to service the installation after a year. All the plumbing and heating engineers I dealt with have been thoroughly competent, skilled and reliable and their work has been to a consistently high standard. They are not the cheapest but I guess you get what you pay for. I can certainly thoroughly recommend them.

I have had two jobs done recently. A boiler replacement/new radiator and then a couple of weeks later I had Hive heating control fitted. The jobs were completed on time, no mess and very professional. I would highly recommend FirmusHeat.
