    I have a couple of people coming to quote for a new boiler.
    I currently have a condensing boiler which heats the rads and the hot water cylinder in the airing cupboard. I do not want to go to a combi boiler , so assuming no ugly surprises, I am looking at a straight boiler replacement with an average size Worcester Bosch boiler. What is a reasonable quote?

    Any good questions to make sure I ask to ensure quote covers what it should.

    I would be expecting £1800-£2200.
    Is it a regular Boiler or a System Boiler?

    Plus VAT

    £1200-1500? Really?! Seems too good to be true.

    I recently knew someone have a 24kW heat-only (which means boiler does not include pump or means for expansion) condensing boiler replaced on an existing open-vented system, as a straight swap (or as close as such a thing exists), for £1650. But it was a messy install, looked rubbish, and generally poor, and so I no longer recommend that gas installer to anyone.

    Ask how long the job takes. Ask how he determines whether a chemical cleanse or power flush is required.

    IMO you cannot do a swap AND a proper PF in a morning, although some claim to.

    It really depends on your system , size of property. We just converted one and we had long pipe runs, a lot to chase and box. Just get a couple of local engineers in to quote for you. Sometimes it's better to pay a little more for a good decent install. It's also the aftercare between you and the engineer which is important. You could build a trustworthy relationship. A very good engineer who looks after you is rare nowadays. All you want is someone honest,transparent and has the eye for details.
