How Often Should You Service Your Boiler?
We recommend booking a boiler service once a year to ensure your heating system is running safely and efficiently. Regular servicing helps to catch potential issues early, improve energy efficiency, and prevent costly breakdowns.
If your boiler is less than 5 years old, an annual service is usually enough to keep it in top condition. However, if your boiler is over 10 years old, you may start to experience reduced efficiency or minor faults, so keeping up with servicing is even more important.
✅ Newer boilers (under warranty) – Most manufacturers require an annual service to keep the warranty valid. Skipping a service could void your warranty, leaving you to cover repair costs.
✅ Older boilers (10+ years) – Boilers over a decade old can become less efficient and more prone to faults. If you notice any issues (such as strange noises, fluctuating heating, or higher energy bills), you may need more frequent servicing or consider upgrading.
✅ Landlords & rented properties – If you’re a landlord, you’re legally required to have an annual Gas Safety Check, which includes a boiler inspection.
No matter the age of your boiler, an annual service ensures safety, efficiency, and peace of mind.

All boilers need regular servicing to help maintain the system and keep it running effectively. It is recommended that your boiler is serviced once a year. Like anything, if you continue to maintain it well and regularly, you will be less likely to face issues with it in years to come.
If you are having problems with your boiler we recommend that you get it looked at sooner rather than later, to prevent any further damage or issues. Boilers are an essential part of any home!
