Could anyone give a rough guesstimate of the cost of replacing a gas-fired,
warm air CH boiler (which also drovides domestic hot water) with a direct
replacement?

My mother-in-law lives in Carlisle and when she rang her usual boiler
maintenance guy to ask the question, he said that he was doing one right at
the moment and that it was £2600. This is for old boiler out, new boiler in
and bringing it up to current regs, which we thought was quite reasonable -
especially when compared to all the cost and hassle of replacing the dry
system with a wet system and running copper pipes and new radiators into
each room.

However, my wife's sister has sown the seeds of doubt into her mother's mind
by saying that that's a rip-off - "Our boiler was only £400 and the complete
system, all rads and pipework, was installed, parts and labour, for that
price" - was apparently what she said.

But what she maybe failed to take into account was that her house was being
completely renovated - floorboards were already up, walls were just bare
brick, and no time had to be spent in moving furniture, lifting carpets
etc., etc., which would all have to be done and would cause considerable
upheaval and labour costs at her mothers house.

So, is £2600 a reasonable quote for what she needs?

Cheers,

John.
