Guide
Which boiler do I need?
Bedrooms, bathrooms and mains pressure decide the answer. Here's the short version.
Combi
1-3 beds, 1 bathroom
A 25-30kW combi is almost always the right call.
Combi / system
3-4 beds, 1-2 bathrooms
A 30-35kW combi if the mains is strong, otherwise a system boiler.
System
4+ beds, 2+ bathrooms
System boiler with an unvented cylinder so showers can run together.
Regular
Older gravity system
Regular boiler keeps the loft tanks — cheapest like-for-like swap.

Frequently asked questions
How long does a boiler installation take?
A straight combi swap is usually a single day. Conversions, back boiler removals and system changes normally take two days.
Is the price on the website the price I pay?
The online figure is an indicative range inc VAT. Once we've done the free survey the written quote is fixed — we don't add extras afterwards.
Are you Gas Safe registered?
Yes. Every engineer is Gas Safe registered and every install is notified to Gas Safe and Building Control on your behalf.
Do you offer finance?
We can spread the cost of a new boiler — ask when you get your quote and we'll send over the options.
