Does Your Boiler Needs Fixing?

Boilers don’t usually die without warning. Learn to spot the signs and you can avoid the worst of it:

Strange noises

Kettling, banging, weird gurgling sounds – they all mean something. They often point to trapped air, low pressure, or a part starting to fail.

Won’t stay running

Boilers that keep cutting out are trying to tell you something. Usually something’s not quite right with the sensors or safety systems.

No hot water or heating

When nothing’s heating up, something’s definitely wrong. Whether the taps are running cold or the radiators aren’t warming up.

Leaks or damp patches

Water around the boiler or nearby pipework is never normal – it’s a sign something’s not sealed properly.

Bills going up

If your gas bill’s climbing but you’re not using more heating, the boiler’s probably working too hard. Often means it needs cleaning or adjusting.

Why Get Your Boiler Serviced?

Most people wait until something breaks. Smart people get it checked once a year and avoid most problems altogether.

Stay safe

Gas appliances can be dangerous if they go wrong. Carbon monoxide poisoning is rare but deadly. Worth checking for.

Save money on bills

Clean, well-adjusted boilers burn less gas. The service usually pays for itself through lower bills.

Avoid disasters

Small problems become big problems if you ignore them. Much cheaper to fix a worn seal than replace a whole heat exchanger.

Keep it running longer

Looked-after boilers last fifteen years, sometimes more. Neglected ones pack up after eight or nine.

Very professional outfit indeed. Did complete ripping out of old and installation of new boiler and water cylinder in two days flat, took great care while they were in the house and left it spotless afterwards. Also diagnosed a piping issue that nobody else who’s worked on my system had ever spotted, let alone diagnosed. Recommend without reservation.

Frequently Asked Questions

Why is my boiler losing pressure?

Boiler pressure loss is usually caused by leaks in pipework, radiators, or valves, or a fault with internal components like the expansion vessel or pressure relief valve. While topping up occasionally is norma – especially after bleeding radiators – frequent pressure drops often indicate a failed vessel diaphragm or a leak that requires professional attention.

Check for mineral deposits or staining around your radiator valves and look for drips from the small copper pipe outside your property. If you can’t see a visible leak, the issue may be hidden under floorboards or within the boiler itself. Our expert engineers provide comprehensive boiler servicing and repairs to identify the root cause and get your heating system back to peak efficiency.

How frequently should my boiler be serviced?

To maintain your manufacturer’s warranty and ensure your home stays safe, you boiler should be serviced every 12 months. Regular annual maintenance is the best way to catch minor issues – like worn seals or soot build-up – before they escalate into expensive emergency repairs or total system breakdowns.

Beyond fulfilling warranty requirements, a professional service by a Gas Safe or OFTEC registered engineer optimises your boiler’s efficiency, which can significantly lower your monthly energy bills. We recommend booking your service during the summer or early autumn to ensure your heating is in peak condition before the winter chill sets in.

What’s the lifespan of a boiler?

Most boilers last around 10 to 15 years if they’re looked after properly. Some go on for longer, especially if they’ve been serviced every year and any small problems have been sorted early. Once a boiler starts needing regular repairs or struggling to heat the house, it’s usually more cost-effective to replace it.

What does a boiler service include?

While the specific steps depend on your boiler’s make and model, a professional service ensures your system is safe, efficient, and compliant with warranty requirements. Our engineers perform a comprehensive range of checks, including a thorough visual inspection of the flue and ventilation, internal cleaning of heat exchangers and condensate traps, and a test of all safety components to prevent future breakdowns.

For gas boilers, we focus on measuring combustion efficiency, checking gas pressure, and cleaning system filters. For oil boilers, the service also includes replacing the oil nozzle and flexible hoses, cleaning the burner, and inspecting the fuel supply and fire valves. Following the service, you will receive a full report detailing the work carried out and any recommendations to improve your system’s longevity.
