A new boiler.
Chosen for your home.

What to have ready, and when a survey comes first

For a quote, send your postcode, photos of the boiler and its data label, the controls, and where the flue leaves the outside wall, taken from a normal standing position. Do not remove the casing or touch any gas fitting to take photos.

A like-for-like replacement in the same position can start with the online price. Moving the boiler, a new flue route, a back or floor-standing boiler, changing the system or any unusual job is assessed at a survey first, using the request form. We do not fit oil boilers or warm-air units. Your written quotation names the installer, who your contract is with, and your warranty and workmanship guarantee.

Replacement, conversion or a more involved installation?

A replacement in the same position is different from changing boiler type, moving the boiler or altering the heating system. Tell us about cylinder or tank removal, extra radiators, controls and pipework changes so these can be considered in the quotation.

Explore boiler conversions and system changes or compare combi, system and regular boilers.

Need a replacement urgently?

Call 0800 118 2128 or 0203 143 3883 to check urgent availability. Tell us whether you have heating or hot water, who is affected, and your full postcode. A diagnostic visit may establish that repair is a suitable option.

Installation timing depends on assessment, the agreed scope, suitable equipment, access and installer availability. A same-day or next-day installation is not confirmed until it has been agreed with you. For a suspected gas escape, use the emergency instructions rather than the booking form.

Start your quote remotely

Send photos of the boiler and its label, existing controls, accessible pipework, the visible flue position and any hot-water cylinder or tanks. Take photos only from a safe, accessible position; leave covers and fittings in place.

Include your postcode, property type, bathroom count, current heating and hot-water problems, and what you want to change. We review this information and confirm whether further questions or a property assessment are needed. A telephone or video discussion can be requested; its suitability and availability must be confirmed. Photos alone do not guarantee a final fixed price.
