If you’re wondering how often should a boiler be serviced, keeping on top of regular maintenance can make a big difference to the safety, efficiency and reliability of your heating. Leaving too long between services could mean small problems go unnoticed, potentially leading to higher energy bills, unexpected breakdowns or costly boiler repairs.
There are also other factors to consider, including the age of your boiler, your manufacturer’s warranty requirements and whether you’re a homeowner or landlord.
In this guide, we’ll explain how frequently you should get your boiler serviced, what can happen if you don’t and when is the best time to book. We’ll also cover servicing costs, legal requirements and what happens during an annual service.

You should generally get your boiler serviced once every 12 months. An annual boiler service allows a qualified engineer to check that everything is working correctly and identify any issues that may have developed since the last service.
Most boiler manufacturers recommend having your boiler serviced annually, and keeping up with this schedule may also be a condition of your warranty. Rather than waiting for a fault to appear, regular checks can help identify potential problems before they affect your heating or hot water.
You should also consider arranging a service if:
Older boilers or systems that experience particularly heavy use may need closer attention. Your heating engineer can advise whether additional maintenance is appropriate based on the age and condition of the appliance.
An oil boiler should also generally be serviced every 12 months. Regular maintenance can help keep the appliance working safely and efficiently while identifying wear, leaks or other potential problems. For an oil-fired system, it’s recommended to use an OFTEC registered technician with the appropriate qualifications and experience. They’ll be able to carry out the checks required for your particular boiler and advise if any further maintenance is needed.
Your boiler is one of the most important appliances in your home, particularly during the colder months. Having it serviced regularly can help maintain safe operation, support efficiency and reduce the likelihood of problems going unnoticed.
Safety is one of the biggest reasons to arrange an annual service. A Gas Safe registered engineer can check your gas boiler and its key components to make sure they’re working safely. These safety checks can help identify problems with combustion, the flue or other components that could otherwise go unnoticed. Regular servicing can also help reduce the risk of issues associated with carbon monoxide, which is particularly dangerous because you can’t see, smell or taste it.
Over time, wear, dirt and other issues can affect how efficiently your boiler operates. An annual check gives your engineer an opportunity to assess its performance and make sure it’s working properly. Keeping an efficient boiler can help prevent unnecessary energy use. While servicing can’t guarantee lower energy bills, a boiler that’s maintained and operating correctly is less likely to waste energy because of an undetected fault.
Not every boiler problem causes an immediate breakdown. Issues such as corrosion, unusual boiler pressure, leaks or worn internal components can develop gradually. Having your boiler serviced regularly gives an engineer the chance to spot these problems sooner. Addressing smaller faults early could help you avoid costly boiler repairs and reduce the likelihood of losing your heating unexpectedly.
Many manufacturers require you to get your boiler serviced every year as part of their warranty or guarantee conditions. Failing to arrange an annual service could therefore affect your cover if you need to make a claim later. Requirements vary between manufacturers, so always check the terms of your boiler warranty. Keeping a record of each service can also provide evidence that the required maintenance has been completed.
Missing a service doesn’t mean your boiler will immediately stop working. However, without regular servicing, developing faults can go unnoticed and potentially become more expensive to fix.
If you don’t get your boiler serviced, you could experience:
Regular maintenance can’t guarantee you’ll avoid boiler repairs altogether. However, it gives a registered engineer the opportunity to identify problems early and check that your boiler is running safely.
You can get your boiler serviced at any time of year, as long as you stick roughly to a 12-month schedule. However, late spring and summer can be convenient because your heating is used less and engineers may have greater availability.
Booking during the warmer months also gives you time to address any problems before your central heating system is needed more regularly in winter.
If you can’t remember your last service, check any paperwork or service records you have. If you’ve recently moved, you could also ask the previous owner. If there’s no reliable record, it’s sensible to arrange a service so your boiler can be checked and you have a clear date for future servicing.
Whether you’re legally required to arrange boiler checks depends on whether you’re a homeowner or landlord. However, regular servicing is recommended regardless, as it helps keep your heating system safe and working correctly.
If you own and live in your home, there’s no general legal requirement to get your boiler serviced every year. However, an annual service is recommended for safety and maintenance, and most boiler manufacturers require regular servicing to keep their warranty valid. Any work involving a gas boiler should be carried out by a suitably qualified Gas Safe registered engineer.
Landlords have a legal responsibility to arrange an annual gas safety check for relevant gas appliances and flues they provide in rental properties. This must be completed by an engineer listed on the Gas Safe Register. A gas safety check isn’t exactly the same as a full boiler service, so landlords should make sure they’re meeting their legal obligations as well as following the manufacturer’s servicing recommendations.
A boiler service involves a series of checks to assess the safety, condition and performance of the appliance. While the exact process can vary depending on the type and manufacturer, your heating engineer will typically:
You can read our full guide to what a boiler service includes for a step-by-step look at what happens during an appointment.
A typical boiler service takes around 30 to 60 minutes. However, the exact time will depend on the type, age and condition of your boiler. It may take longer if your heating engineer discovers a fault or additional work is required. Any necessary boiler repairs will usually be discussed with you before further work is carried out.
The boiler service costvaries depending on your location, boiler type and the company carrying out the work. As a general guide, a one-off gas boiler service in the UK typically costs around £70 to £110, although prices can vary.
Oil boiler servicing may cost more, while some homeowners choose boiler cover or a care plan that includes a yearly service alongside other benefits. Always check exactly what’s included before choosing a plan.
Keeping your boiler serviced every 12 months can help maintain safe and efficient performance, identify potential faults and reduce the risk of unexpected problems with your heating and hot water.
