Most domestic boilers should be serviced once every 12 months by a suitably qualified engineer. Annual servicing helps ensure your boiler is operating safely and efficiently, identifies potential problems early, and may be required to maintain your manufacturer’s warranty.
If your boiler appears to be working normally, it’s still important not to skip its annual service. Problems can develop inside a boiler without immediately affecting your heating or hot water.
How Often Should a Boiler Be Serviced?
For most domestic boilers, once every 12 months is the recommended servicing interval.
Annual servicing allows an engineer to check the boiler’s condition, safety controls and operation. If your boiler is under warranty, check the manufacturer’s terms, as regular servicing may be a condition of the warranty.
Keeping your service records is also useful if you need to make a warranty claim or track your boiler’s maintenance history.
Why Is Annual Boiler Servicing Important?
Regular servicing can help:
Keep your boiler safe
A qualified engineer can check important safety components, combustion and the flue system to make sure the boiler is operating as it should.
Identify problems early
Servicing can reveal issues such as worn components, corrosion, leaks, pressure problems or combustion faults before they develop into more serious problems.
Maintain efficiency
A properly maintained boiler can operate more effectively than one that has been neglected, helping your heating system work as intended.
Protect your warranty
Many manufacturers require regular servicing as part of their warranty conditions. Always check the specific requirements for your boiler.
What Happens During a Boiler Service?
The exact checks depend on your boiler and the manufacturer’s instructions, but a typical service may include:
- Visual inspection of the boiler and accessible components
- Checking the flue and ventilation
- Gas pressure and combustion checks
- Inspection of relevant boiler components
- Checking safety controls
- Checking system pressure
- Identifying signs of damage, corrosion or leaks
- Recording the service and any issues found
If the engineer discovers a problem, they should explain what needs attention and advise you on the appropriate repair.
When Is the Best Time to Service Your Boiler?
You can service your boiler at any time of year, provided you maintain the recommended 12-month interval.
However, late summer or early autumn can be a convenient time to have it checked before you start relying heavily on your heating during winter.
The important thing is not the particular month but making sure your annual service is not missed.
Does a New Boiler Need Servicing?
Yes. A new boiler should still generally be serviced every year.
Regular servicing helps make sure the appliance continues to operate correctly and can also help you meet the manufacturer’s warranty requirements.
Check your boiler documentation for the manufacturer’s specific servicing requirements.
What Happens If You Don’t Service Your Boiler?
Skipping an annual service doesn’t necessarily mean your boiler will immediately stop working. However, it means potential problems may go unnoticed.
You could face:
- Unexpected boiler breakdowns
- Undetected safety issues
- More expensive repairs
- Reduced reliability
- Warranty problems where servicing is a warranty condition
Regular servicing is usually much easier than dealing with an unexpected heating failure in the middle of winter.
Signs Your Boiler May Need Attention
Don’t wait for your annual service if your boiler starts behaving unusually.
Contact a qualified heating engineer if you notice:
- Unusual banging, whistling or gurgling noises
- Repeated loss of boiler pressure
- Frequent boiler lockouts or resets
- Radiators taking unusually long to heat
- Water leaks around the boiler
- Sooty or unusual staining
- The boiler repeatedly breaking down
These symptoms don’t necessarily mean the boiler needs replacing, but they should be investigated.
Boiler Service vs Gas Safety Check
A boiler service and gas safety check are not the same thing.
A boiler service involves inspecting and maintaining the boiler to help ensure it operates safely and correctly.
A gas safety check is a specific safety inspection of relevant gas appliances and flues.
For landlords, an annual gas safety check is a legal requirement for the relevant gas appliances and flues in their properties.
If you’re unsure which check you need, speak to a qualified Gas Safe registered engineer.
Can I Service My Own Boiler?
No. You should never attempt to service a gas boiler yourself.
Gas boiler work should be carried out by an appropriately qualified Gas Safe registered engineer.
How Long Does a Boiler Service Take?
A straightforward boiler service will often take around 40 minutes to an hour, although the time can vary depending on the boiler, its condition and whether the engineer identifies any problems.
