Our new condensing combi came to about £1400 all in (fitting, disposal, new boiler, basic pipework). It was a painfully expensive christmas that year.

Paid a local co about £1500 a few years back to replace ours when British Gas wanted £3500.

As the boiler was about £400, I expected 2 blokes and a whole day's work when one turned up and took about 3 hours, so still a rip off. He made sure that the replacement fitted the original pipework exactly so no extra work had to be done there as well.

totally depends on what needs doing!
a new condesing boiler setup proerly will not take 3 hours to install and most likely you will need your system cleaning out and if the system is dirty and the boiler installed on a dirty system your warrenty will be void.
if its a straight swap then about £1500-£1700 and the boilers and parts don't cost £400 i can't even get them that cheap and i work for a boiler manufacture!
if it needs a flush put £350 on that if it needs a power flush as its a days work and about £150 for a manual flush.

don't just get the cheapest guy to do it as i bet he is st most good trades men charge more because they can as they have good reps.
don't get british gas to do it as there are a rip of and most there guys are useless.

I got a local company to fit our new boiler, £550 all inclusive. Did a super job.

I bought the boiler from B&Q. It was £800-£1000 on the net. B&Q had it for £600, and had a special with £100 off, I also got it on a 20% off weekend, so was £450 including all the bits.

I ended up paying £2000 earlier this year. Cheapest quote was £1400, but the old boiler had different size fittings to standard ones, so needed a bit more work to get the whole system up to scratch.

Well worth it as the old one was a sack of crap and would stop working randomly. Then died all together. Gas bill was cheaper since the new boiler install.

oh dear i would not buy a boiler from b&q. sorry but they are cack.
£550 labour and say £100 fitting about right for a straight swap. like i said though most will need a fluch and will invole extra work.
also bear in mind if you don't have a room thermostat you will need one to comply with part l building regs and that can add more dosh to it.
every installation is different so very hard to price it up over here!

I paid 3.5k but I had to have all the pipes changed as they were lead to copper ones. Was not happy.

i work for them and we do not sell boilers to b&q! also we haven't sold any chaf stuff for about a year not and only ariston stuff exsist now apart from the water heater which are great! been around without a design change since 1978 and still sell very well and still lot going from that age so can't be to bad!

to be fair i think your best bet would be to get a decent local engineer in and get a well spec'ed boiler and a fluch done and go from there.

£1,273.47 to £2k - assuming a few pipe and electrical mods are required to fit it.

Slightly OT, but related - is the flue system different for a condensing system vs an older system, and if so, what's the likely cost? (I ask as I didn't budget for a new flue for my logburner recently - ouch!)

Thanks, and sorry OP - but might be useful for you, too.

£1500-£2k. My quote from an independent 3+years ago said that the power flush charge would be reduced to £100 if it was done at the same time as the installation, however he says that nowadays boiler manufacturers insist on a power flush as a condition of the guarantee. Stupid not to have it done anyway.

Got a Worcester-Bosch with Honeywell controls, very pleased with it.

Errr what? You work for Ariston? I am confused, our last boiler was Ariston and it was crap, total and utter crap! In the 4 years we hd it (was installed by the previous owner) it had virtually all its bit replaced, some twice, and indeed when we got rid of it last year when it was 7 years old, the only original bit was the external case!

I've got a Worcester Bosch 24CDi, had it installed at the same time as my heating so can't help on install costs but the boiler itself was 680 + VAT from Plumbase IIRC

Good piece of kit as well.

i can't see how people have so many parts fitted to one appliance. i would normally blame the engineer not picks stuff up on annual services! bear in mind it would have to be a big leak to cause the outer casing to corrode and that should be picked up on a service.
or are you one of these people who think its a white box that doesn't need service and moan when it breaks? bit like a car you look after it genrally it will look after you and ok some faults can appear but thats with any product but if something is noglected it will have a shorted life span.
also we are not in the era of using a basic bunner and cast iron heat exchangers any more as people want efficent so they won't have a 30-40 year life span!

I just changed mine and put a valliant combe boiler in, I used to have a potterton boiler with a water tank. Cost around £3500, but that included taking the tank out and away, and the associated pipework...

I thought the price was ok.. but looking at this thread looks like I overpaid a bit...

not really if you hd tanks and so on then that is not a straight boiler swap!
people don't seam to also understand how much pipe and fittings are parts cost for a system either!
plumbers will charge alot of money but if you think your pay a guy £100 labour for a boiler swap then he will bodge it up to be out there door asap and that in the long run will cost you more money and alot more greif.

This man speaketh the truth.

Coverting a system boiler to a condensing combi is not a few hours work.

System may be under gassed (new 22mm feed from meter)
Re-route hot and cold feeds, flow and return.
New flue
Run condensate
Powerfush system
Install TRV's if not there
Install room stat if not there
Sign off electrical work to Part P
Sign off gas work to Corgi/Gas Safe

Not a gas fitter myself but used a company a few times who I trust.

To change a system boiler to a Worcester Bosch condensing combi with system flush and the above upgrades as required I'd have thought between £2k-£2.5k to be a reasonable price depending on where you are in the country.
