How Often Should You Service Your Boiler? The Complete Guide

Your boiler is one of the hardest-working appliances in your home, running for hours every day during the colder months. Just like a car needs an MOT, your boiler needs an annual service to keep it running safely and efficiently.

How Often Should You Service Your Boiler?

The simple answer: once a year. Most manufacturers and industry bodies recommend an annual boiler service carried out by a Gas Safe registered engineer. The best time to book is during summer or early autumn — before the cold weather arrives and engineers get busy.

Why Annual Servicing Matters

• Safety: A service checks for carbon monoxide leaks and ensures safe operation
• Warranty: Most manufacturers require annual servicing to keep your warranty valid
• Efficiency: A well-maintained boiler uses less gas, saving you money on energy bills
• Prevention: Early detection of worn parts prevents costly breakdowns in winter
• Lifespan: Regular servicing can extend your boiler's life by several years

What Happens During a Boiler Service?

A typical boiler service takes 45-60 minutes. The engineer will inspect the boiler and controls, carry out a flue gas analysis, check gas pressure and flow rates, inspect the combustion chamber and heat exchanger, test safety devices, and provide a written service report.
