What a new boiler costs

Typically £4,500 to £6,500 including VAT, depending on the boiler and how much of the existing system needs putting right.

That sits above the £2,000 to £3,000 fixed-price online sellers, and we are not trying to match them. What you get instead is an approved Vaillant or Baxi installation registered for a 10 year guarantee, fitted by a Gas Safe registered and WaterSafe approved contractor rated 4.96 from over 1,200 reviews.

You can get an exact figure without anyone coming to the house. Send photographs and the details, and we will price it free of charge.

Frequently Asked Questions

What does a new boiler cost in London?

A full installation is typically £4,500 to £6,500 including VAT. The figure depends on the boiler, whether the flue or pipework needs altering, and whether you are changing system type. You get an exact price before anything is agreed, and the quote is free.

What does the 10 year guarantee cover?

We are an approved installer for Vaillant and Baxi, so we can register your new boiler for a 10 year manufacturer guarantee. Call 020 3764 2713 and we will talk you through the exact terms before you commit to anything.

How does the free remote quote work?

Send us photographs and details of your current boiler and we price the job without visiting. It costs nothing and there is no obligation. If the job is unusual we will say a visit is needed rather than guess at it.

How long does a boiler installation take?

A straightforward replacement usually takes a day. Changing system type, moving the boiler, or work that needs pipework altering can take two to three days.

What should I look at when choosing a boiler?

Size first. A boiler matched to the number of radiators, bathrooms and occupants will cost less to run than an oversized one. Then the type, which is combi, system or regular depending on your hot water needs. Efficiency in the UK is rated under ErP, and almost every new condensing boiler sits at A, so the rating rarely separates one from another. Correct sizing and good controls make far more difference to your bills than the label does.

Can I change from one type of boiler to another?

Usually yes, though it means changes to the system. Moving from a regular boiler and cylinder to a combi, for example, means reworking pipework and removing the cylinder and tanks. We will tell you what is involved and what it costs before you decide.

Which areas do you cover?

London and inside the M25.
