A boiler service isn’t just a quick check, it’s a vital part of keeping your heating system safe, reliable and running efficiently. Whether you have a combi, system or conventional boiler, regular servicing helps prevent breakdowns, reduces your energy bills and ensures your boiler operates safely all year round.
If you’re unsure how often a boiler should be serviced or what’s included, we’ve created this guide that explains everything you need to know.
How Often Should a Boiler Be Serviced?
A boiler should be serviced every 12 months. This is the industry standard and is also required by most boiler manufacturers to keep your warranty valid.
An annual service helps to:
Check for safety and gas leaks
Keep your boiler running efficiently
Spot potential issues early
Reduce the risk of unexpected breakdowns
Prolong the life of your boiler
If your boiler is older or has had small issues throughout the year, a yearly service becomes even more important.
What’s Included in a Professional Boiler Service?
A Gas Safe registered engineer will carry out a series of checks to make sure your boiler is working safely and efficiently. A standard service typically includes:
Visual inspection of the boiler and pipework
Gas pressure and combustion checks
Flue inspection
Cleaning of key components
Checking for leaks, corrosion or damage
Testing safety devices
Efficiency assessments
Service record updates for warranty protection
These checks ensure your boiler is running correctly and meets all safety standards.
Signs Your Boiler May Need a Service Sooner
While an annual service is the minimum, there are times when you should book a service sooner. Look out for:
Unusual noises such as banging or gurgling
Reduced heating performance
Boiler frequently losing pressure
Higher energy bills without explanation
Radiators taking longer to heat up
Pilot light issues on older boilers
If you’re noticing any of these, it’s worth booking a service or having an engineer inspect the system.
How Servicing Helps Prevent Breakdowns
Most boiler problems don’t appear overnight, they build up gradually. Regular servicing helps spot worn parts, minor leaks and early signs of inefficient burning before they turn into costly repairs or full breakdowns.
This is especially important during winter when boilers work harder and emergency repair callouts are more common.

When’s the Best Time of Year to Service Your Boiler?
Although you can service a boiler at any time, the ideal period is late spring or summer. Here’s why:
Engineers are quieter outside the winter rush
Any issues can be fixed before colder months
Your boiler will be fully prepared for winter use
Booking early ensures you’re not left waiting during the busier winter period.
Why Boiler Servicing Matters for Safety
Boilers that aren’t serviced regularly carry a higher risk of faults, gas leaks or carbon monoxide leaks. As a result, only Gas Safe registered engineers should carry out servicing or repairs.
A proper service makes sure all safety controls and combustion systems operate correctly, giving you peace of mind that your home is protected.
