Replacing an old boiler, switching to a combi, or moving the boiler somewhere better.
An annual service checks your boiler is working safely and keeps most manufacturer warranties valid. Tell us the make, the model and when it was last done.
A service is a planned check of a boiler that is working. If yours has already stopped or keeps locking out, a [boiler repair](/services/boiler-repair/) visit is the right place to start.

They check the boiler is burning and venting correctly, clean parts where the manufacturer asks for it, test the safety devices and check the system pressure.
A flue gas analyser measures how well the boiler is burning, which you cannot see from the outside.

It is also when small problems get spotted early, such as a worn seal, a blocked condensate trap or pressure that is slowly dropping.
