Not sure when your boiler was last checked? You’re not alone. It’s easy to forget, especially when everything seems to be working fine. But boilers give off subtle signs when a service is overdue, and ignoring them can lead to breakdowns, higher energy bills, or even safety issues. Here’s what to look out for before a small issue becomes a big problem.
Key indicators that your boiler is due for attention
Your boiler may still be heating your home, but that doesn’t mean it’s running safely or efficiently. Recognising the early warning signs of wear or internal build-up can help you stay ahead of problems and avoid costly call-outs.
Strange noises and banging
If your boiler has started making unusual noises like banging, gurgling or whistling, it may be a sign of trapped air, limescale, or a failing component. These sounds often indicate that something is not quite right inside the system and should be checked by a qualified heating engineer.
Irregular heating or hot water
A well-functioning boiler should provide consistent heating and hot water. If your radiators are taking longer to warm up or the hot water temperature fluctuates, it could mean internal parts are wearing out or your system needs flushing. This is a common symptom in boilers that haven’t been serviced regularly.
Pilot light keeps going out
A pilot light that won’t stay lit could be due to a faulty thermocouple, blocked jet, or other internal issues. It’s not just an inconvenience; it could be a safety concern. This is particularly important for older boilers that still rely on a standing pilot flame.
Higher energy bills without explanation
If your energy usage habits haven’t changed but your bills are creeping up, your boiler might be running inefficiently. A clogged burner or heat exchanger, or poor combustion, can reduce performance and increase fuel usage. A service helps reset your boiler back to optimal condition.
Foul smells or signs of soot
Any unusual smells near your boiler, especially metallic or burning smells, are a red flag. Soot or black marks around the casing could point to incomplete combustion or blocked flues. These issues need urgent attention to rule out any risk of carbon monoxide.
Boiler warning lights or error codes
Modern boilers are equipped with digital displays or indicator lights. If you’re seeing flashing lights, fault codes, or persistent reset issues, it’s your boiler’s way of asking for help. A service can identify the root cause and reset everything safely.
It’s been over 12 months
Even if there are no obvious symptoms, a boiler that hasn’t been serviced in over a year is likely due. Annual servicing keeps your warranty valid, protects your property, and ensures all safety checks are up to date.
Why an annual service matters
Boiler servicing isn’t just about avoiding breakdowns. It’s also about catching issues early, improving efficiency, and keeping your heating system running smoothly all year. Regular servicing also helps extend the life of your boiler, saving you money in the long run.
