Why annual?
A boiler service catches deterioration in components before it leads to failure. Within a year, combustion performance can drift as components wear slightly, lime scale accumulates on the heat exchanger, and small seal leaks develop. Catching these at service prevents them becoming major faults.
Annual servicing also:
When should you book it?
Ideally: late summer or early autumn (August–October).
This ensures your boiler is checked and ready before the heating season begins in earnest. It's also when engineers are less busy — January and February service appointments are difficult to schedule because demand is at its peak.
What if I've missed a service?
Don't panic — one missed service rarely causes a boiler to fail immediately. But it may have voided your warranty for that period, and any developing fault will have gone undetected. Book as soon as possible.
How long does it take?
A standard boiler service takes 45–90 minutes for a Gas Safe engineer to complete thoroughly.
