We have an existing gas fire that we'd like to convert back to a proper fireplace. Have just discovered that it still has a gas supply to it and is working (we've never used it, previous owners never used it and I had someone out to check it a year or so ago with the possibility of installing a log burner and he said there was no gas going to it!!), so need somebody out to block off the gas supply. I tried B&K in Blackwater but they only do heating. Does anyone have any recommendations? Thank you!
