10 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.Verified reviewerJob location: SW16- EEmma M
10 New gas boiler installation & 5 TRV controls fitted on radiators

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 roundVerified reviewerJob location: CR3 10 Annual boiler service

Seb and his apprentice Lee serviced my boiler today; as before, he kept me informed about arrival time, arrived promptly, and the work was done quickly and efficiently. I'm very grateful to him and would recommend him without hesitation.Verified reviewerJob location: SM510 ⭐️⭐️⭐️⭐️⭐️ Exceptional boiler service

Job location: KT22I recently had my boiler serviced and was genuinely impressed by the work carried out by Seb. From start to finish, the service was professional, thorough, and hassle-free. The engineer took great care to ensure the boiler was running safely and efficiently. Their knowledge and attention to detail were exceptional, and it’s clear they take real pride in their work. I now have complete confidence in my heating system and would not hesitate to recommend to anyone needing their boiler servicing.10 Fantastic service.

Fantastic service, Seb came out to quote wishing a couple of hours of contacting, boiler was condemned and shut off by British Gas. ☹️. Quoted to fit a new boiler and managed to fit us in within 2 working days as we had no heating or hot water. Quote was competitive, Seb was knowledgeable, advice was given on various options. Installation was quick clean and carried out promptly. Heating and hot water resumed. One very Happy customer 😀Verified reviewerJob location: SM610 Gas boiler service

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.
