Why service it every year
Most winter breakdowns start as small faults
A yearly service is the cheapest way to keep the heating on when you need it most.
Fewer breakdowns
We catch worn seals, electrodes and failing parts before they leave you without heating or hot water in the cold.
Safe to use
We check the boiler is burning safely and test for gas leaks, so you know it’s safe to run all winter.
Keeps your warranty valid
Most manufacturers need a yearly service by a Gas Safe engineer to keep the boiler’s warranty valid.
What’s included
A proper service, not a quick look
Every service covers the same checks, whichever engineer you get.
- Gas safety checks, including testing for leaks and checking the boiler burns safely
- Electrodes removed, inspected and cleaned, with a new seal if needed
- Expansion vessel checked for the correct pressure
- Diverter valve tested on both heating and hot water
- Condensate trap checked and cleared
- Magnetic filter cleaned, where one is fitted
- Boiler water temperature monitored for stable running
- Radiators, valves and pipework checked for leaks, and radiators bled where needed
Found a problem? You decide.If the engineer spots anything that needs fixing, they’ll explain it and quote first. Nothing extra is done without your OK.
