Why an annual service matters
A yearly service keeps your manufacturer warranty valid, satisfies most home insurance requirements, and — most importantly — checks for carbon monoxide risks that are invisible without proper testing equipment. It also catches small faults before they become expensive breakdowns.
What happens if you skip it
- Your warranty may become invalid, leaving you to pay full price for repairs
- Small faults go undetected and can develop into full breakdowns
- Efficiency drops gradually, increasing your energy bills
- Carbon monoxide risks go unchecked
Why we do not recommend skipping it “if it seems fine”
| Common assumption | Why it is risky |
|---|---|
| “It is working fine, so it must be safe” | Carbon monoxide leaks often produce no visible or audible symptoms until tested with calibrated equipment. |
| “I will service it every couple of years instead” | Most warranties specifically require annual servicing — skipping a year can void cover entirely. |
What it costs to wait
A service is a small, predictable cost. A breakdown from a missed fault, or a voided warranty leaving you to pay full price for a repair, is almost always more expensive.
