Ok. I thought you wanted help. The_One clearly knows a lot more about boiler repairs than anyone else - so perhaps following his advise is best.
I'm just citing my own experience with Worcester boilers and fixed price repairs. They replaced my heat exchanger and during the process the boiler was in pieces. They were working on it for over an hour and it was fully calibrated afterwards. They state quite clearly under what grounds it would cost more than £275. Awkward placement doesn't appear to be among them.
