How Often Do Older Gas Boilers Need Servicing

As boilers get older, they often require more attention to ensure they remain safe and efficient. While newer models may only need an annual service, older gas boilers can develop wear and tear that makes them more vulnerable to faults. Knowing how often to service your older boiler is an important part of keeping your home warm, safe, and cost-efficient throughout the year.

Servicing Older Boilers to Keep Them Running Safely

Older boilers can continue to provide reliable heat for many years if they are cared for properly, but without regular servicing, they can become inefficient and even unsafe. Servicing is about more than just keeping the boiler working; it ensures harmful problems such as gas leaks or carbon monoxide risks are spotted early.

Annual Servicing as the Minimum

For every boiler, including older models, an annual service is the absolute minimum. This allows an engineer to carry out vital safety checks, clean components, and identify any faults before they become major issues. With older boilers, yearly servicing is especially important, as parts are more likely to suffer from wear and tear.

When More Frequent Servicing Makes Sense

In some situations, servicing older boilers more than once a year can be beneficial. If your boiler is over 15 years old, is struggling to maintain consistent heat, or has a history of breakdowns, it may need a six-monthly service. This provides extra reassurance during colder months when heating systems are under the most pressure.

Warning Signs That Shouldn’t Be Ignored

While annual servicing is important, there are times when your boiler will need attention in between scheduled appointments. Look out for warning signs such as:

  • Strange noises like banging or gurgling

  • Yellow or irregular pilot light

  • Higher energy bills despite normal usage

  • Radiators heating unevenly or taking longer to warm up
    If you notice any of these, it’s best to arrange a service as soon as possible rather than waiting for your yearly appointment.

Considering Replacement Over Time

Even with regular servicing, older boilers will eventually reach a point where replacement is more cost-effective. If your boiler is frequently breaking down, parts are becoming hard to source, or it is over 20 years old, a newer model will offer better efficiency, reliability, and safety. An experienced engineer can advise whether continued servicing or upgrading is the smarter option.

  • Extends the lifespan of your boiler
