How often should a boiler be serviced?

Once a year. That is the short answer, and it is what almost every manufacturer warranty requires. But there are better reasons than the small print.

What a service is for

A boiler burns gas in a small space, thousands of times a year. Over twelve months the burner and heat exchanger collect deposits, seals harden and the expansion vessel slowly loses its charge. None of that stops the boiler working. It makes it work less efficiently, then less reliably, and in rare cases less safely.

A service catches those things while they are cheap. Most of the faults we find — a weeping valve, low system pressure, a sticking diverter — cost less to fix on the day than one winter call-out.

What ours covers

• The case opened, burner and heat exchanger inspected and cleaned
• A flue gas analysis, which shows how cleanly the gas is burning
• Pressure, expansion vessel, safety valves and condensate trap checked
• Controls and thermostat tested
• A written report the same day, with a fixed price for anything worth fixing

Why cheap services are cheap

A £40 service is usually a visual check and a flue reading, with the case never opened. It gets you a stamp in the book. It does not get you a clean heat exchanger.

Landlords

The law requires a gas safety check on every gas appliance in a rented home every 12 months, and a copy given to the tenant. Our landlord certificate is £69 for up to three appliances, or £139 with a full service.
