Been quoted a figure in region of 1500 quid for supply and install of new Worcester 65000 BTU boiler. The last time a Corgi guy changed a CH pump for me he charged me almost double for the pump - I guess some mark up is to be expected and is in with his overall price - I assume he would just add on the difference in the fitting charge if I supplied my own parts? I'll get him to break down the quote for the boiler, but what would be a reasonable fitting charge for that type of boiler/reasonable mark up on the boiler itself? It would be an almost like for like replacement of the current boiler in the kitchen. Am I better off shopping around for my own boiler (on line maybe) and getting him to fit it - he told me he does fit things people buy themselves.
