Key takeaways
- Standard home insurance does not cover boiler breakdown. Wear and tear is excluded from every policy as standard.
- A home emergency add-on can cover boiler failure, but only if your boiler has been serviced annually by a Gas Safe registered engineer: the single most common reason claims are rejected.
- If your boiler is more than 10 to 15 years old, check the age limit in your policy schedule. Most add-on policies will not cover older boilers.
Most home insurance policies do not cover boiler breakdown. That answer holds across virtually every standard policy in the UK market, and the reason is straightforward: boiler failure is treated as wear and tear, not as a sudden, unexpected insured event. Insurers cover the damage a boiler causes when it fails, a burst pipe, an escape of water, a flooded kitchen, but the broken boiler itself is your problem to fix. The distinction matters, and it catches homeowners out regularly.
Does home insurance cover boilers as standard?
No. Home insurance is designed to cover sudden and unexpected events: fire, storm, flooding, theft, subsidence. A boiler that deteriorates over years of use and eventually stops working is none of those things. The Association of British Insurers reports that the average home insurance claim across Q1 2026 reached £6,340, driven almost entirely by weather-related events and structural damage. Boiler breakdown does not feature in that picture because insurers do not write standard policies to include it.
The technical distinction is between a sudden, fortuitous loss and gradual deterioration. Your policy will pay for water damage if a corroded pipe bursts and floods your ground floor. It will not pay for the corroded pipe, the failed pump, or the heat exchanger that caused the burst. The same logic applies to the boiler itself.
With around 23 million UK homes dependent on gas boilers and an estimated 107,000 boiler breakdowns occurring each year, costing homeowners approximately £32 million annually in repair bills according to industry data, this gap in standard cover is not a niche problem. It is the default position for every homeowner who has not actively added cover.
What does cover your boiler, and what does it cost?
There are two routes available through a home insurance policy, and understanding the difference matters before you assume you are protected.
| Cover type | Covers boiler breakdown? | Typical cost | Key condition |
| Standard home insurance | No, wear and tear excluded as standard | ~£379/yr combined (ABI Q4 2025) | N/A |
| Home emergency add-on | Yes, subject to policy terms and conditions | ~£69/yr additional (NimbleFins survey data) | Annual Gas Safe service required; age limits apply (typically 10–15 years) |
Does home insurance cover boilers through a home emergency add-on?
Sometimes, and conditionally. A home emergency add-on, typically around £69 per year when added to a buildings policy, will usually cover the cost of an engineer callout and emergency repair when your boiler fails. Most policies cap the claim at between £500 and £1,000 per incident, covering parts and labour, with a contribution toward replacement if the unit is beyond economic repair and under a specified age, commonly seven years.
