Annual Boiler Service Contract Cost
£100–£200
typical UK range
Updated
An annual boiler service contract costs £100–£200 per year in the UK. This typically covers your annual boiler service plus priority call-out. More comprehensive plans (including parts and labour cover) cost £15–£40 per month. Here's what to look for and whether it's worth it.

How much does each option cost?
| Type / scope | Typical cost | Notes |
|---|---|---|
| Service-only annual contract (local engineer)Annual boiler service booked and paid upfront or by direct debit. No repairs or parts included. Good value if your boiler is relatively new | £80–£150 | Annual boiler service booked and paid upfront or by direct debit. No repairs or parts included. Good value if your boiler is relatively new |
| Service plus priority call-outAnnual service with guaranteed priority response (e.g. 24-hour call-out) for breakdowns. Parts and labour charged separately if needed | £100–£180 | Annual service with guaranteed priority response (e.g. 24-hour call-out) for breakdowns. Parts and labour charged separately if needed |
| Full boiler cover (service + parts + labour)Annual contract covering service, priority call-out, parts, and labour for repairs. British Gas HomeCare, Vaillant Care, and similar plans fall in this range (£15–£40/month) | £180–£480 | Annual contract covering service, priority call-out, parts, and labour for repairs. British Gas HomeCare, Vaillant Care, and similar plans fall in this range (£15–£40/month) |
| Boiler and central heating coverCovers boiler plus radiators, pipes, and controls. Comprehensive but expensive. Typically £20–£50/month from national providers | £240–£600 | Covers boiler plus radiators, pipes, and controls. Comprehensive but expensive. Typically £20–£50/month from national providers |
| Landlord gas safety + service contractCombined annual service and CP12 landlord gas safety certificate — the most efficient option for rental property owners | £110–£180 | Combined annual service and CP12 landlord gas safety certificate — the most efficient option for rental property owners |
What affects the price?
- Level of cover — a service-only contract is the cheapest; adding parts and labour cover increases cost significantly
- Provider — local independent engineers are typically 20–40% cheaper than national providers (British Gas, Homeserve) for the same level of cover
- Boiler age — many national providers won't cover boilers over 15 years old, or charge significantly more for older units
- Whether a CP12 is included — for landlords, a combined service and certificate contract is more cost-effective than separate arrangements
- Excess — some plans have a per-claim excess (e.g. £60) that reduces the annual premium but adds cost when you claim
- Location — national providers charge uniform rates; local engineers reflect local labour rates
What's included in the price?
- Annual boiler service (combustion analysis, heat exchanger cleaning, safety checks, system pressure check)
- Gas tightness check
- Benchmark service record update
- For cover plans: parts and labour for boiler repairs (up to plan limits)
- For cover plans: priority response time guarantee (often 24 hours for emergencies)
- For landlord plans: CP12 Gas Safety Record
How long does it take?
The annual service element takes 45–75 minutes — same as a standalone boiler service. Emergency call-outs under a cover plan depend on the response time guarantee specified in the contract (typically 24 hours for priority plans). In practice, engineer availability varies by provider and season — winter call-out times can exceed stated response times even with the best cover plans.
Do I need one?
A service contract is worth considering if: (1) you want the simplicity of a set annual cost for boiler maintenance; (2) you prefer a direct debit arrangement over remembering to book an annual service; (3) your boiler is approaching mid-age (7–12 years) and the probability of a breakdown is increasing; (4) you want parts and labour cover for peace of mind. Service-only contracts are straightforwardly good value for any gas boiler. Full cover plans (with parts and labour) are more debatable — calculate whether the plan cost exceeds the likely repair costs for your boiler's age and condition.
How do you avoid overpaying?
- Use a local independent engineer rather than a national provider for a service-only contract — prices are typically 20–40% lower for the same quality of service
- For newer boilers (under 5 years old), a service-only contract is often better value than full cover — new boilers rarely need expensive repairs
- Compare plan excess levels — a plan with a £60 excess per claim may have a lower annual premium; decide based on how often you expect to claim
- Check whether the plan includes your boiler manufacturer's warranty requirements — some manufacturer warranties require an annual service by a registered engineer to remain valid, which a service contract satisfies
- For landlords, negotiate a combined service and CP12 rate with a single engineer — more cost-effective than two separate arrangements

Frequently asked questions
We’re happy to answer all your questions.
Is a boiler service contract worth it?
A service-only contract (£80–£150/year) is almost always worth it — it ensures your boiler is serviced annually, which maintains warranty validity and catches faults before they become breakdowns. Full cover plans with parts and labour are more debatable — compare the plan cost to expected repair costs for your boiler's age and decide accordingly.
What is the difference between a service contract and boiler cover?
A service contract covers the annual maintenance visit only — it doesn't pay for repairs or parts. Boiler cover (like British Gas HomeCare or Homeserve) covers service plus parts and labour for breakdowns. Service contracts are significantly cheaper; cover plans provide greater financial protection.
Which is better — British Gas or a local engineer?
For service-only, a local engineer is typically cheaper and often provides more personalised service. For full cover plans, national providers have larger networks and may respond faster in an emergency. Local engineers increasingly offer service + priority call-out packages that compete favourably in both price and service quality.
Can I get a service contract for a landlord property?
Yes — many gas engineers offer landlord service contracts that include both the annual boiler service and the required CP12 gas safety certificate in a single annual visit. These combined contracts are the most cost-effective arrangement for landlords and many letting agents negotiate portfolio rates.
Does a boiler service contract renew automatically?
Usually yes — most service contracts auto-renew by direct debit. Check the contract terms for the cancellation notice period (usually 30 days) and whether the price is fixed for the contract term or subject to annual increases.
