Like-for-like combi swap? If you're replacing a combi boiler in the same location with a standard horizontal flue, our fixed prices above apply with no extras. We'll confirm this when you get in touch — it only takes a few questions.
Our installation price is not a starting point. Every job includes the following as standard, with no add-ons or surprise charges on the day.
Extras that may apply: Extended flue runs beyond 1 metre, boiler relocation, additional pipework, magnetic filter upgrade, and smart thermostat installation are quoted separately and agreed in advance.
Tell us your current boiler type, location and property. We'll confirm your fixed price — usually the same day. No engineer visit required for standard swaps.
Accept your quote and choose your installation date. We send written confirmation with everything included. A deposit secures your booking.
Our Gas Safe engineer arrives with everything needed. Your new boiler is installed, commissioned and certificated — usually within a single working day.
