Standard landlord insurance covers a boiler against insured perils, such as fire, flood or escape of water damage, but not against breakdown from age, wear or faults. Breakdown needs a home emergency or boiler cover add-on. Separately, the law requires gas appliances in a let property to be safety-checked every 12 months by a Gas Safe registered engineer.
TL;DR · LAST REVIEWED 21 July 2026
- Buildings cover treats the boiler as part of the building: insured perils yes, breakdown no.
- A boiler that simply stops working is wear and tear, which every standard policy excludes.
- Home emergency or boiler breakdown add-ons fund the call-out, labour and often parts, within limits.
- Gas safety checks every 12 months are a legal duty on landlords, separate from any insurance.
- A boiler failure that damages the property, such as a leak, can produce a valid buildings claim even though the boiler repair itself is not covered.
KEY FACTS
- Home emergency add-ons carry per-call-out and annual limits, and often boiler age limits.
- Some products exclude boilers over a stated age or without service history.
- Annual boiler servicing preserves both the add-on cover and the manufacturer warranty.
- The Gas Safety (Installation and Use) Regulations require the 12-month check and a record given to tenants.
- Escape of water from a failed boiler is a standard insured peril for the resulting damage.
When does standard landlord insurance pay for a boiler?
When the boiler is damaged by an insured peril: destroyed in a fire, ruined by flood, damaged maliciously, or harmed by another insured event. It does not pay when the boiler fails through age, wear, scale, or component faults, which is breakdown and sits outside buildings cover.
The boundary is the same one running through all property insurance: sudden external events are insured, the gradual deterioration of machinery is not. A boiler is plumbing and plant within the building, so when the insured perils strike, fire, flood, storm damage to the flue, a burst elsewhere that drowns the unit, the boiler is reinstated with the rest of the damage. What buildings cover never promises is that the boiler will keep working. Ignition failures, pump wear, heat exchanger scale, printed circuit faults and the general mortality of a machine running daily for years are maintenance events, excluded as wear and tear on every standard wording. The distinction produces an outcome that surprises landlords: a boiler that leaks and wrecks a kitchen floor generates a valid escape of water claim for the floor, the ceiling below and the redecoration, while the boiler repair itself, the cause, stays the landlord's own bill. Reading a policy with that boundary in mind removes most boiler disputes before they start: the question is never whether the boiler matters, but whether an insured peril or a worn part stopped it.
What does home emergency or boiler cover actually add?
An emergency response service: an approved engineer's call-out, labour and usually parts for sudden boiler and heating failures, plus commonly plumbing, electrics and security emergencies, all within per-incident and annual limits. It is a service contract for urgent failures, not an extension of buildings cover.
Home emergency cover exists because a tenanted property converts every boiler failure into an urgent obligation. A cold rental in January is not a wait-for-a-quote situation: heating and hot water sit at the core of a landlord's repairing obligations, and the practical question is who attends tonight and who pays. The add-on answers both with a claims line, an engineer network and defined limits, typically a cash cap per call-out, a cap per year, and rules about what counts as an emergency versus routine repair. The small print carries the product's real shape: many policies exclude boilers above a stated age, require evidence of annual servicing, cap replacement contributions when a boiler is beyond economic repair, and exclude pre-existing faults known before cover started. Standalone boiler cover from energy companies and specialists competes in the same space with service plans that bundle the annual service itself. For a landlord, the comparison is straightforward arithmetic against one emergency call-out plus the value of the tenant relationship: the products are rarely expensive relative to a single uninsured winter failure, provided the age limits and service conditions are actually met.
What are a landlord's legal duties on the boiler regardless of insurance?
Gas appliances, including the boiler, must be safety-checked every 12 months by a Gas Safe registered engineer, with the record given to tenants; heating and hot water must be kept in repair as part of the landlord's statutory repairing obligations. Insurance does not discharge either duty.
The legal layer runs entirely separately from the insurance layer, and confusing them is expensive in both directions. The Gas Safety (Installation and Use) Regulations require every gas appliance and flue in a let property to be checked every 12 months by a Gas Safe registered engineer, with a gas safety record provided to existing tenants within 28 days of the check and to new tenants before they move in; failures carry criminal liability, and no insurance product substitutes for the check. Alongside it, landlords carry statutory repairing obligations covering heating and hot water installations, which is why a dead boiler in a tenanted property is a legal problem as well as a practical one, with timescales judged by the season and the household. The two layers interact quietly: an insurer or home emergency provider investigating a claim may ask for the service and safety history, and a boiler with no paper trail hands them an exclusion. The efficient landlord habit is one visit: an annual service and the 12-month safety check booked together, producing the record the law requires and the history the cover relies on.
How should a landlord actually structure boiler protection?
Layer it: buildings cover for insured damage, a home emergency or boiler product for breakdown response, the manufacturer warranty while it lasts, and the annual service plus 12-month gas check as the maintenance spine. Sized against boiler age, the layers cost little next to one winter failure.
The complete answer is a small stack rather than a single product, and the boiler's age decides the emphasis. A new boiler leads with its manufacturer warranty, often lengthy when installed and serviced by accredited engineers, and the annual service exists partly to keep that warranty alive; home emergency cover in those years is buying response speed more than repair economics. A mid-life boiler is the add-on's natural territory, old enough to fail and young enough to pass the product's age limits, and this is where per-call-out and annual caps deserve reading against realistic repair costs. An old boiler inverts the logic: age exclusions and beyond-economic-repair caps shrink what cover will pay, and the honest financial plan becomes a replacement fund and an installer relationship rather than premiums, with the escape-of-water risk of an ageing unit adding its own argument for planned replacement. Through every stage the constants are the buildings policy answering insured damage, the 12-month gas safety check answering the law, and the service history answering every future claims investigator. Landlords who keep those three current rarely find the boiler question difficult.
Boiler protection checklist for landlords
- Confirm your buildings policy's position: insured perils covered, breakdown excluded.
- Check the boiler's age against any home emergency product's age limits before buying.
- Book the annual service and the 12-month gas safety check as one visit.
- Give tenants the gas safety record within 28 days of the check.
- Keep the service history filed; cover and warranties depend on it.
- For old boilers, budget replacement rather than relying on capped breakdown cover.

Frequently asked questions
Does landlord insurance cover boiler breakdown?
Not as standard. Buildings cover pays for boiler damage from insured perils such as fire or flood; breakdown from age or wear needs a home emergency or boiler cover add-on.
Is a leak from a broken boiler covered?
The water damage usually is, as escape of water is a standard insured peril. The repair of the boiler that caused it is generally not, unless breakdown cover is held.
Do landlords have to service the boiler every year?
The legal requirement is a gas safety check every 12 months by a Gas Safe registered engineer, with the record given to tenants. An annual service is not the same thing but is usually done together and protects warranties and cover.
Does home emergency cover replace an old boiler?
Rarely in full. Products cap contributions when a boiler is beyond economic repair and often exclude boilers over a stated age. Old boilers are better answered by a replacement budget.
Who pays for the boiler in a rented flat?
The landlord, under statutory repairing obligations covering heating and hot water, unless the lease places the installation elsewhere. The freeholder's block policy insures the building; the flat's boiler duties normally sit with the flat's landlord.
