How much is a new boiler from British Gas?

The first step in acquiring a price for a new boiler from British Gas is to book an appointment via their website.

After providing a full address, customers are prompted to choose a type of appointment either by video call or home visit before selecting a suitable date.

When the date arrives, a British Gas engineer will assess the current boiler installation and provide a fixed price quote. This can be quite a lengthy process, which essentially incurs costs for the engineer and salesperson’s time, too, which will be added to your overall cost.

There are no definitive boiler installation prices available if you book a home survey from a British Gas engineer, but a combi boiler replacement quote from most installation companies starts at around £1,800.

British Gas’ new combi boiler prices vary drastically due to the fact they install many boilers from different boiler companies.

British Gas boiler replacement quotes & Local Heroes

British Gas new boiler replacement quotes now include the use of Local Heroes to install boilers on their behalf. They will arrange for a new boiler to be sent to your home and then will arrange a local boiler installer from Local Heroes to fit your boiler. This saves you and British Gas money, so the savings are passed on to you

If you want a British Gas heating engineer to install your boiler, expect to pay over £500 more for the same new boiler installation. Each boiler is slightly different to install, some easier than others, and they all vary in price coming from the manufacturer.

Every home is different. Some homes use a lot more water as they have more occupants, more rooms, or more mains-powered showers. These homes will require a bigger boiler with a higher output, which will increase the price of installation.

If you have a smaller home, with one or 2 occupants then the cost of your boiler may be lower as your hot water demand is likely to be a lot lower.

You must tell British Gas all this information as accurately as possible to get the right combi boiler for your home.

Boiler installations in London and the surrounding areas, as with everything else in these areas are generally more costly due to demand. Read our new boiler cost price guide for further information.

Read some of our superb solar panel installation reviews from Trustpilot

Recently had solar panels fitted by Green Central and I can’t speak highly enough of the team. The whole experience has been trouble free and I would recommend them to anyone thinking about having solar panels installed – 10/10!

Rob Schofield


Our installation is now complete! 8 solar panels fitted and the journey from initial consultation through to the end product has been seamless.
Hats off Green central, Credit where it’s due.
Will definitely spread the word!



Recently had six solar panels fitted on my house by Green Central and I couldn’t have asked for a better service. In particular, I have to highlight the exceptional communications through out, the over all smooth running process and completely stress free experience, all down to Green Central. I now have grid independence which is valuable beyond estimation.
