Quick answer
Your boiler should be serviced every 12 months by a Gas Safe registered engineer. Most manufacturers require an annual service to keep the warranty valid, and regular servicing keeps your boiler safe, efficient and less likely to break down.
Why service your boiler every year?
- Safety. A service checks your boiler is burning gas safely and the flue is working correctly.
- Warranty. Most manufacturer warranties require a yearly service by a Gas Safe engineer.
- Efficiency. A well-maintained boiler uses less gas.
- Reliability. Small problems are spotted before they become breakdowns.
What does a boiler service involve?
Your engineer will inspect the boiler and flue, check gas pressure and combustion, clean or check key components, test safety devices and controls, and record the service for your warranty.
When is the best time to book?
Any time of year is fine, but booking in late summer or early autumn means your boiler is ready before the cold weather arrives. Book your boiler service.
