A like-for-like combi boiler replacement typically costs between £1,800 and £3,500 fully installed, depending on the brand and complexity. We provide free fixed-price surveys with no obligation.
How long does an air conditioning installation take?
Single-room wall-mounted split systems take a minimum of one full day to install. Multi-room systems take two or more days. We'll confirm the exact timeframe during your free survey.

Yes. We issue Gas Safety Certificates (CP12) for landlords across Sevenoaks and Kent following an annual boiler and gas appliance inspection. Legally required for all rental properties.
How often should a boiler be serviced?
Once a year, ideally in late summer or early autumn before the heating season. Annual servicing keeps most manufacturer warranties valid and significantly reduces the chance of a mid-winter breakdown.
