It’s easy to ignore your boiler until something goes wrong. But just like a car, it needs regular servicing to keep it safe and efficient. The question many London homeowners ask is: how often should you get your boiler serviced?
The Simple Answer
Once a year. That’s the standard recommendation from boiler manufacturers, energy companies, and Gas Safe engineers alike.
Why Annual Servicing Matters
-
Safety – engineers check for gas leaks and carbon monoxide risks.
-
Efficiency – a clean, well-tuned boiler uses less energy, saving money.
-
Reliability – small issues like worn seals or dirty components are fixed before they cause breakdowns.
-
Warranty protection – most new boilers require annual servicing to keep the warranty valid.
What Happens During a Service?
A Gas Safe engineer will:
-
Inspect the boiler and flue.
-
Check gas pressure and flow.
-
Clean key components.
-
Test safety devices.
-
Give advice on any wear and tear.
It usually takes less than an hour but provides peace of mind for the whole year.
Signs You Might Need an Extra Check
While once a year is enough for most, call an engineer sooner if you notice:
-
Strange noises (kettling, banging).
-
Pilot light going out.
-
Pressure dropping regularly.
-
Radiators not heating properly.
London-Specific Considerations
Hard water in London means limescale can build up more quickly, sometimes justifying more frequent checks or system flushing.
To sum up – annual boiler servicing isn’t just a box to tick. It’s a simple step that keeps your home safe, warm and energy-efficient. Book it once a year and you’ll avoid most of the costly surprises.
