Hi All,
Thought I'd better come to a forum to get some advice, as to be honest I feel like I'm going a bit crosseyed with the advice so far from plumbers.
Basically, I've just bought a 1920's semi detached 3 bed 2 storey 1 bathroom house in London, which amongst several cool period features has a not quite so cool Potterton Diplomat boiler (floor mounted in kitchen cupboard), very old hot water tank (in bathroom on 1st floor above boiler) and 8 very old radiators installed.
The boiler has been serviced and maintained annually by the previous owner, and appears to work well. However my gas meter becomes a blur when I switch the boiler on, the archaic timer has now packed in, and I can hear "bits" of metal (?) sloshing around in the radiators, so I think its time to get the whole lot replaced!
Having got some advice and quotes from 2 plumbers, I am told that the following works are top notch but not excessive for our requirements (about right for the property now but will allow for future expansion of the property e.g. converting the roof to 2 more bedrooms and an ensuite). The cost is £6,500-00 all in.
Basically, I wondered if anyone could give me a street on whether the cost is about right, and whether the works are indeed roughly appropriate and not overly excessive. The spec is as follows: -
