Does Home Insurance Cover Your Boiler?

It catches a lot of people out, usually in January: "My boiler has packed up, but the home insurance will sort it." For most households that is not how it works, and finding out mid-breakdown is the worst time to learn it.

This guide sets out what a standard home insurance policy does and does not do when it comes to your boiler, and how the alternatives compare. We sell boiler cover ourselves, so read the second half knowing that, and we have tried to be straight about when you do not need it.

The short answer

Standard buildings and contents insurance does not cover boiler breakdown. If the boiler stops working because a part has worn out, failed or simply got old, your normal policy will not pay to repair or replace it. Wear and tear, gradual deterioration and mechanical or electrical breakdown are standard exclusions in UK home insurance.

To be covered for a breakdown you need a separate product: a boiler cover plan, or home emergency cover, which some insurers offer as an add-on for an extra premium.

What standard home insurance does cover

This is where the confusion comes from. Home insurance will not fix a broken boiler, but it usually does pay for the damage a sudden failure causes.

• Escape of water. If the boiler or its pipework suddenly leaks and water ruins a ceiling, a floor, plaster or your belongings, that damage is normally covered under the escape of water section of buildings and contents cover. The insurer pays to put the ceiling right. They do not pay to fix the boiler that caused it.
• Trace and access. Many policies include some cover for the cost of finding a hidden leak and making good afterwards, for example lifting a floor to reach a pipe. Check whether yours has it and what the limit is.
• Frost damage. A burst from freezing is often covered, though some policies exclude it if the house was left unheated and unoccupied for a set number of days in winter.
• Accidental damage. If you have accidental damage cover and the boiler is physically damaged by a one-off event, you may have a claim. A slow failure is not an accident in the insurer's eyes.

The pattern is consistent: home insurance covers sudden, unforeseen damage. It does not cover an appliance wearing out. Read your policy wording rather than relying on the summary, because exclusions and excesses differ between insurers.

Your three options for breakdown protection

• A manufacturer's warranty. A new boiler comes with a parts and labour warranty from the manufacturer. Length depends on the brand and the installer. Worcester Bosch offers up to 12 years and Vaillant up to 10 when fitted by one of their accredited installers, which we are. While the warranty is in force, genuine faults are the manufacturer's problem, not yours. The one condition almost every warranty carries is an annual service by a Gas Safe registered engineer. Miss one and the cover lapses.
• Boiler cover or home emergency cover. A monthly or annual plan that pays for repairs, usually includes the annual service, and often extends to the wider heating system. Predictable budgeting. You pay a fixed amount and call when something goes wrong. Plans vary a lot in what they exclude, so the comparison below matters.
• Pay as you go. No plan, no monthly fee. You call a Gas Safe engineer and pay for the repair when one is needed. Cheapest if your boiler is reliable, but you carry the risk of a big bill if a major part fails.

How they compare

• Buildings and contents insurance. Covers damage from a leak. Does not cover breakdown. Already part of your premium.
• Manufacturer's warranty. Covers parts and labour for genuine faults on a newer boiler. Comes with the boiler. Needs an annual service to stay valid.
• Boiler or home emergency cover. Covers repairs and usually a service. A monthly or annual cost. Read the exclusions.
• One-off repair. Costs whatever the fault costs to fix, when it happens. No standing charge.

Is boiler cover worth it? An honest view

The case for it: predictable costs, and a phone number to ring when the heating goes off. That suits households who would struggle to absorb a sudden repair bill, and it is genuinely useful on an older boiler that is more likely to fail. Having the service bundled in means it actually gets done.

The case against it: over several years the payments can add up to more than you would have spent on the odd repair, particularly on a newer boiler. Many plans have an excess, a cap on claims, a list of parts they will not replace, and an age limit. Some will not take on a boiler over a certain age, and most reserve the right to declare a boiler beyond economical repair and pay out nothing towards a replacement. That is exactly the moment you were paying for.

Our take, even though we sell it:

• Boiler under manufacturer's warranty. You almost certainly do not need separate cover. The warranty already protects you. Just keep the annual service up.
• Boiler out of warranty, still in good order. This is where cover makes sense if a surprise bill would hurt. If you could absorb one, paying for a service each year and repairs as they come is usually cheaper.
• Boiler old and breaking down often. Cover providers know this too, which is why they load the price or refuse. The money is usually better put towards a replacement.

What a plan costs is set by the boiler's age, what the plan includes (boiler only, or boiler plus controls, radiators and pipework), the excess, and whether the annual service is in. Ask for those four things in writing before you compare plans on the monthly figure alone. Our own boiler cover page sets out what ours includes and excludes.

Questions to ask before you buy any cover

• Is there an excess per call-out?
• Is there an annual claims limit?
• Is the boiler's age or make excluded?
• Is the annual service included, and does the plan lapse if it is missed?
• What happens if the boiler is declared beyond economical repair? Some plans contribute to a replacement, most do not.
• Is there a no-claims period at the start? Many plans will not cover anything in the first few weeks.
• Who turns up? A national plan may send a different subcontractor each time. A local plan sends the same engineers who know your system.

What this means for you

Whether you have a new boiler under a long warranty or a twenty-year-old unit that is limping along, the principle is the same. Do not assume the home insurance will rescue a broken boiler. Check your warranty status first, keep the annual boiler service up to date because it is the thing that keeps every other form of cover valid, and then decide on a plan with your eyes open.

Frequently asked questions

Does home insurance cover a leak from my boiler?
Usually it covers the damage the leak causes, such as a ceiling or floor, under escape of water. It does not pay to fix the boiler or the pipe that leaked.

What is the difference between a warranty and boiler cover?
A warranty comes with a new boiler and covers genuine faults for a set number of years, provided you service it annually. Boiler cover is a plan you pay for separately and is mainly useful once the warranty has run out.

Can I add boiler breakdown to my home insurance?
Many insurers offer home emergency cover as an optional extra. It is a separate section with its own limits and exclusions, so treat it like any other boiler cover plan and read what it leaves out.

Will the insurer pay for a new boiler if mine floods the kitchen?
No. They will pay for the kitchen. The boiler is yours to sort.
