Thanks to all...
I've just had a stolen boiler replaced, like for like, by a CORGI reg'd plumber. Less than 2 hours work for 400 quid, and some hassle if you read my other thread. Tiny little things too, like he scorched the white enamel where you can hardly notice it, but he shouldn't've scorched it at all. And the pipes arent exactly parrallell, and stick out further than necessary from the wall. I'm getting a safety check, for £60, on this guys work tomorrow.
Too frustrating having a buzy tradesman rushing to fit me in between jobs. In future, I'll alwaysdiy it, and get a gas safety check. I have some idea about pipe sizes and flue locations, bu I'll read up on it before I do any gas work myself.
............... A job I might want to do myself is put a gas fire in without lifting much of the laminate floor. I think it's doable with one sub-floor weld at most, but I don't think I'd find someone else to do it. ............................................. The car analogy is interesting. Supposing the headlights weren't working at all, and I had an accident at mid day, I don't think the lights, an mot fail, could be an issue as far as the insurance company was concerned, since they didn't contribute to the accident. ............................................ Another interesting point raised: If a CORGI plumber did the gas work, and the house blew up, then his competence is in doubt despite his qualification.
Thanks again tony
