So i guess i deserved to have a complete stranger take me for a fool and try to rip me off. I am not sure i follow your logic on this i am sorry. The bottom line is this plumber came into my house which is fairly large and have a big car on the drive, he assumed (wrongly) i would not miss the odd few hundred quid. My point is that his first thoughts were how he could rip me off with inflated prices. Not how he could offer a fair value for money service. £2800 + VAT just to replace my boiler with a combi, and a small one that i know for a fact would not be suitable for the job, is just wrong i am sorry. If you think it is ok to rip people off if you think you can get away with it then i guess we just have different outlooks on life and shall agree to disagree.
