Could I please have a recommendation for a gas certified plumber, possibly to come out today. We had our boiler condemned probably 2 months ago now, we had a carbon monoxide leak upstairs in the boiler cupboard so it was condemned, work was done on the boiler and in the loft and the reading was within the safe limit but apparently he couldn't take the sticker off because there was still a slow gas leak from the meter up to the boiler as our pressure is low. This was over a month ago and he hasn't been back since. Last night we lost all pressure and had nothing so my husband put the pressure up to 1.5 as advised in the past and a few moments later there was a loud bang, water gushing out in the airing cupboard and a smell of burning so at 11pm we had to drag both kids out :( help!
