Cost of replacing conventional boiler with a combi?

[msfreud]

Has anyone had a conventional boiler replaced with a combi recently? How much was it?

I've had one quote so far and it's in the region of £3k which is actually less than I was expecting, given this is London. (Although he has a Kent postcode - but only just!) It includes a room thermostat (Honeywell), two replacement radiators, magnetic filter, power flush, removing all rubbish and old water tanks etc. that I would expect.

Will get more quotes but just interested in ballpark figures as well.

We've just had a quote to replace a hot water tank, boiler and 15 new radiators with all associated plumbing. Large 5 bed house, quote was around £6,000 excluding Vat. It is an unvented pressurised system which I've been led to believe is the best for our needs (and 1/2 of the new radiators are style).

Why are you going for a combi?

Oops, i meant are column style which bumps the price up.

Going for a combi because
A. Small terraced house with one bathroom and so no need to use hot water in two parts of the house at the same time
B. Current water tanks are downstairs and consequently hot water pressure is rubbish, tanks would need moving upstairs if kept conventional boiler
C. With the above in mind, a combi will be the most economical in use.

We have just had new 40kWh combi boiler, moved from kitchen up into bathroom,pipes from mains replaced with 22mm copper piping,digital thermostat, powerflush, inline descaler and some other stuff done for £3k

Ours was 3k. To remove old combo boiler and gas fire. Replace with combo boiler, take away all rubbish etc and they also had to do something or other with something electrical (sorry for being technical)

Remove old back boiler I mean, oops

Ours was £4k it's a Valliant Combi and our house is big over 3,300 ft but it doesn't do our top floor where we have another smaller boiler.
