Boiler cover and service plans are ongoing paid products, separate from the guarantee that came with the boiler when it was installed. Before buying one, or renewing one automatically, it is worth checking what you already have and reading what the plan actually promises to pay for.

Check whether you already have cover

Citizens Advice guidance points out that boiler or home emergency cover is sometimes already included, and households pay for a second, overlapping plan without realising it. Before buying a standalone policy, check:

• whether your home insurance already includes home emergency or boiler breakdown cover;
• whether a packaged bank account you hold includes boiler or home emergency cover as a benefit; and
• whether an employer benefit or a scheme you already pay into covers a broken boiler.

If more than one policy could apply, compare the terms and conditions rather than assuming either one is sufficient, since cover levels and exclusions between a bundled benefit and a dedicated boiler plan can differ significantly.

What a boiler cover plan typically includes

Plans vary between providers, but the areas to check on any policy are the same:

• Parts and labour – is a breakdown call-out included, and are both parts and labour covered, or only one;
• Annual service – is a yearly service included as part of the plan, or charged separately;
• Response times – what is promised for how quickly an engineer will attend, particularly if the household has no other heating source;
• Call-out limits – whether there is a cap on the number of call-outs or total claim value per year; and
• Excess – any fixed fee you pay per claim regardless of the fault.

Read the exclusions, not just the headline cover

The exclusions section is usually where the real difference between plans shows up. Common exclusions worth checking for specifically include pre-existing faults, sludge or scale damage where the system has not been maintained, inaccessible pipework, third-party heating controls not supplied by the provider, and a requirement that the boiler has been regularly serviced – sometimes specifically by that provider – for a claim to be valid. If a provider is entitled to declare the boiler “beyond economical repair” rather than fix it, check what that means for your policy: whether you receive a contribution towards replacement, or simply a refund of remaining premiums.

Cover plan vs manufacturer guarantee vs warranty

A cover plan is not the same thing as the guarantee that came with a new boiler at installation. A manufacturer guarantee is typically free, tied to the specific appliance, and usually requires proof of annual servicing to remain valid – it does not need a monthly payment to keep going. A cover plan is a separate, paid product that can extend protection beyond the manufacturer guarantee, cover call-outs for other parts of the heating system, or provide cover once the manufacturer guarantee has expired. If your boiler is still within its manufacturer guarantee period, check what a cover plan actually adds on top of that before paying for both.

Renters and landlords

If you rent your home, Citizens Advice is clear that your landlord is responsible for repairing or replacing a broken boiler once you have reported the fault, and this is not something a tenant needs a separate cover plan to arrange. Landlords, in turn, are legally required to have gas appliances checked annually by a Gas Safe registered engineer and to provide tenants with a current gas safety record.

Whoever attends, check they are Gas Safe registered

Regardless of which cover plan or provider you use, only a Gas Safe registered engineer is legally permitted to work on a gas boiler in Great Britain. Ask to see the engineer’s ID card when they arrive, and check what work they are qualified to carry out – not every registered engineer is qualified for every type of gas appliance. You can check an individual’s registration using their licence number on the Gas Safe Register website before work begins.

Frequently asked questions

Is boiler cover worth buying for a brand-new boiler?

Often not immediately, if the boiler is already covered by a manufacturer guarantee. Check what the guarantee covers and for how long before adding a paid plan on top – a cover plan becomes more relevant as the guarantee period runs out.

Does boiler cover include the annual service needed to keep a manufacturer guarantee valid?

Sometimes, but not always – check the policy specifically. If it does not, you still need to arrange and keep evidence of an annual service yourself to avoid invalidating the separate manufacturer guarantee.

Can a cover plan refuse a claim because the system was not serviced?

Yes, this is one of the most common exclusions. Missing or unproven servicing history is a frequent reason plans decline to pay out, which is why keeping service records matters even after you have taken out cover.
