    Boiler install/service/gas pipe fix.

    Posted 11 December 2025

    Had a bit of an issue when I accidentally drilled through the gas pipe. Seb was able to fix quickly, and for a very reasonable price. Had him install and service boiler for a few years now, would have no hesitation in recommending.

    New gas boiler installation & 5 TRV controls fitted on radiators

    Posted 11 December 2025

    Excellent service from start to finish. Clear communications and smooth installation. Seb and Levi worked so effectively together. The work was completed in a day and they left everything clean and tidy afterwards. They were a pleasure to have in the house. They were very friendly, knowledgeable and professional. I had Seb over last year to cap off my old gas fire. I found him very honest and genuine. I knew then that I could trust him when it came to the major job of having my ancient boiler replaced. Until then I had struggled to find a trustworthy gas safe engineer to do a job. 5* all round

Hi my name is Seb, after years of successful trading in the Gloucestershire area we have moved back to the South West London area which is home. I completed a full apprenticeship in 2002, and became gas registered in 2003.

I pride myself on working to a high standard, I'm known for my honesty (a rare quality in this trade). I have a vast range of experience in all aspects of the domestic gas industry. So please don't hesitate to call with any boiler, central heating, cookers and gas related issues or needs.
