Combi or system?
Not sure which one you need?
For smaller homes with one bathroom, a combi is usually the right call, lower upfront cost, compact, no need for a hot water cylinder.
For larger homes with two or more bathrooms, or where several people shower at similar times, a system boiler delivers better pressure across multiple outlets.
Water pressure at the mains and the size of your existing pipework both matter. As part of our free survey, we'll check both and tell you honestly which type fits best.

Common questions
Frequently asked
How long does a new boiler installation take?
A straight combi swap is usually a one-day job. A full system install (cylinder, pipework, flue relocation) can take two to three days. We'll confirm the timescale in your written quote.
What size boiler do I need?
Boiler size is measured in kW output, and depends on the number of radiators, bathrooms, and the insulation of your home. We'll size it properly during the free survey, never oversized (wastes fuel) or undersized (struggles to heat).
Do you remove the old boiler?
Yes, removal and responsible disposal are included in the quoted price. We leave your home clean.
Is 0% finance really 0%?
Yes, on qualifying installs, 0% APR means no interest is added for the length of the agreement. You pay the same total whether you pay in full or over 12/24 months. Subject to status.
What warranty do I get?
Warranty length depends on the brand and model, from 5 years at the lower end up to 12–14 years on select Vaillant and Atag installs. We register the warranty for you on installation day.
Do you handle Building Control notification?
Yes. Every install is notified via Gas Safe Register, which automatically satisfies Building Control. You'll receive a certificate in the post.
