How Often Should You Service Your Boiler?

8 October 2025

When life gets busy, your boiler probably isn’t top of the to-do list - especially when it seems to be working just fine. But just like a car, your boiler needs regular servicing to keep it running safely and efficiently.


So, how often is too often? And what happens if you leave it too long?


Let’s break it down.


Why Regular Boiler Servicing Matters

Boilers are one of the most relied-on systems in your home or workplace - and when they go wrong, it can cause real disruption.


An annual service helps to:


  • Catch faults early, before they become bigger (and pricier) problems
  • Keep your boiler running efficiently, which can lower energy bills
  • Extend the lifespan of your system
  • Ensure safety - especially when it comes to things like gas leaks or carbon monoxide

For landlords: It’s a legal requirement to carry out an annual gas safety check for tenant safety. While this isn’t the same as a full boiler service, arranging both together is best practice to keep boilers safe, efficient, and compliant.


So, How Often Should You Book a Service?

In most cases, the recommendation is once a year.
This helps keep your warranty valid, ensures everything’s working as it should be, and gives you peace of mind heading into winter.
