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?

You may need to replace the lockshield valves as well depending on their
age and condition.

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.

If all goes smothly, perhaps 10 mins / valve. All going smothly assumes
that the pipework does not need moving to accomodate the new valve.

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

That kind of implies a resaonable amount of pipework alterations...

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

Boiler is something like 800 plusc, so 1K ish for fitting. Sounds like
you have a couple of man days worth of work there to do at least, so not
unreasonable.

Having said that, I don't think much to the choice of boiler. The
efficency is pretty poor at under 80%, and the HW flowrate is nothing
special for the money.
