I posted a while back on this but seems the situation is harder than I thought...our extension was finished 18 months ago but the builder never arranged the building completion certificate. We were quite relaxed about it at first as we had not paid the final £1000 and there were a few snags that needed doing and he was down the road doing an extension at our neighbour's. A few months ago I got fed up of the 'I'll come and sort it' broken promises so arranged the final inspection myself. All was fine apart from me not having job completion certificates for the electric and gas work which the builder had subcontracted. I can't get building regs without obviously. I thought if he's not playing ball I could get other contractors to check and certify the work but it turns out that's not possible. I've phoned the council, other contractors, Gas Safe and the IECC but no one can offer me a solution apart from getting the original contractors back but the builder is still not keeping his promises. He does answer my calls but doesn't do anything and I dont know what to do next! Do I threaten him with court or something?
