I'm in the process of getting central heating system installed in my house. So far I've had 2 quotations.
It's a 3 bedrooms terraced house over 2 floors. The companies suggested I would need 9 radiator panels and a combination boiler.
Company A quoted me £4580 (with a Ideal combinaton boiler).
Company B quoted me £4160 (with a Vaillant combination boiler).

What I want to know are these prices fair for the work requires or I could get better prices looking around.
Another question I have is how reliable are these combination boilers and any particular brand is better?

Any comments would be most appreciated.

Bit expensive.

When comparing quotes check where they're proposing to put the rads:
under windows/on outside walls is best, back to back on inside walls is
cheap'n'nasty.

They're pretty reliable, though when they do break down you have no
backup for either heating or hot water so you have to get them fixed PDQ.

Vaillant have a good reputation. Ideal are not bad though there seems to
be some issue with the Isar/Icos condensing boilers (see recent-ish
thread). Check (google) recent threads with discussions of boilers for
pros & cons.
