The three main reasons
- Safety: Servicing checks for carbon monoxide risk using calibrated equipment that cannot be replicated at home
- Warranty: Manufacturers require proof of annual servicing to keep cover valid
- Efficiency and cost: A well-maintained boiler uses less energy and is less likely to break down unexpectedly
Why we do not recommend skipping it
| Common assumption | Why it is risky |
|---|---|
| “No smell, no problem” | Carbon monoxide has no smell or colour — the only way to know is proper testing. |
| “I will service it if something goes wrong” | By the time something goes wrong, the warranty may already be voided from missed services. |
What it costs to wait
A missed service can void your warranty, let small faults develop into breakdowns, and leave carbon monoxide risks unchecked. The cost of the annual service is minor compared to any of these outcomes.

Frequently asked questions
Is servicing a legal requirement?
It is not a legal requirement for homeowners, though it is for landlords under gas safety law. It is, however, almost always a condition of your boiler’s warranty.
What if my boiler seems to be running fine?
Carbon monoxide leaks and internal wear are often invisible without testing — a boiler can seem fine and still have a fault.
