Getting a 13 yr old gravity fed boiler system replaced by a Halstead Ace
High combi boiler system.

Would this require replacing any existing radiator pipework to prevent
excessive noise or leaks due to the increased pressure - currently got 8mm
radiator pipes not sure about underfloor piping?

Also, while they're doing the installation I've asked for them to replace
the 12 radiator valves with thermostatic ones. How long is this likely to
take to do seeing as the system is bled anyway.

Also, the hot water tank is being replaced by a closet radiator (as the
missus wants an airing cupboard still).

Current quote is £1800 including the boiler - does this sound reasonable or
is it only me that thinks I'm being ripped off :-) ?

That depends on your location, the specs of the system you want and to
a lesser extent on the system you've got.

Boiler itself makes a huge difference. E.g. Worcester Bosch Greenstar
combi 30HE and 40HE plus differ by close to 500 pounds. Let alone
differences between manufactures. Then: condensing boilers are more
expensive and usually require a bit more work to get rid of the
condensation. I have had plumbers in two different places, and
Sheffield plumbers cannot be beaten for price. So, location has
adverse effect on quotes in my experience.

I would have thought a straighforward boiler swap for below 2000 is
not bad to begin with. But why don't you get another quote. I got
three and went with the cheapest.
