Boiler service in London

An annual service is the cheapest thing you can do for a boiler. It catches the parts that are on their way out before they strand you in January, and most manufacturer warranties require it — a skipped service is one of the commonest reasons a warranty claim gets refused.

Before you call

Worth knowing first

Some of this may save you a callout entirely. We would rather tell you than not.

Book it before the cold, not during it

Everyone discovers their boiler has a problem on the first genuinely cold week of the year, which is exactly when engineers are hardest to get. A service in late summer or early autumn costs the same and is far easier to book.

A service is not the same as a repair

A service is an inspection and clean. If it finds a failed part, replacing that part is separate work and we will price it before doing anything. Nobody should be presenting you with a bill you did not agree to.

Keep the paperwork

Manufacturers ask for evidence of annual servicing when a warranty claim is made. Keep the record somewhere you can find it — the difference between a free repair and a paid one can be a piece of paper.

What a service will not tell you

A service checks the boiler, not the whole system. If your radiators are cold at the bottom or the system is full of sludge, that is a separate problem and needs a flush rather than a service.

Questions

Common questions

How often should a boiler be serviced?

Once a year. Most manufacturer warranties require it, and a service that has been skipped is a common reason a warranty claim gets refused.

How long does a boiler service take?

Usually under an hour for a straightforward domestic boiler, longer if the engineer finds something that needs investigating. We would rather take the extra time than sign off something that is not right.

What is the difference between a service and a repair?

A service is a scheduled inspection and clean. A repair fixes a specific fault. If a service turns up a failed part, we price that separately and get your agreement before replacing it.

Do you service boilers you did not install?

Yes. It makes no difference to us who fitted it.
