Boiler install/service/gas pipe fix.
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

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.
