Boiler installation in London

Coping with no heating or hot water is never ideal, which is why we work to provide you with access to a prompt, professional boiler installation in London and across the UK. Our installers usually have next-day appointments available, so we could have your new boiler fitted and fired up in as little as 24 hours.

Plumbers can’t install gas boilers; only Gas Safe registered engineers can. It is illegal for anyone without the necessary accreditations to install a gas boiler. We don’t recommend that you get a handyperson to install any type of boiler, electric or gas, as they won’t have the necessary training to do the job to a high standard.

No, unless you are Gas Safe registered and have the necessary experience, you can’t install your own boiler. You can carry out routine maintenance checks yourself, such as checking the system pressure and bleeding radiators, but a trained and qualified professional must carry out any installation jobs or more in-depth maintenance.

This depends on the type of boiler and whether it’s a like-for-like installation. If you’re getting a new combi boiler installed in the same place as your existing boiler, the installation should take no longer than a day. If you need a system or standard boiler installation (both of which will require an additional hot water tank) or you’re moving your boiler from one place to another (i.e. from your kitchen cabinet into an airing cupboard), this could take several days to complete. When you book your boiler installation with BOXT, one of our London-based engineers will be able to advise you on how long it’s likely to take.

BOXT only provides boilers from reputable manufacturers, so you know you’re getting a home heating system you can trust. Our engineers work local to you across all London boroughs, installing Worcester Bosch, Navien, Vaillant and Baxi boilers.

We install combi, system, and standard boilers across London. The best type of boiler for your home will depend on your heating and hot water demands. To find the right boiler for your needs, enter your postcode, and we’ll provide you with tailored recommendations to suit your usage needs.
