Landlord Boiler Cover UK: The Complete 2026 Guide (CP12, Costs & Cover)
Everything UK landlords need to know about boiler cover in 2026 — legal duties, CP12 gas safety certificates, what a good policy includes, and how to keep tenants safe without overspending.
If you let property in the UK, your boiler is the single biggest source of tenant complaints, emergency call-outs and unexpected bills. The right landlord boiler cover turns an unpredictable expense into a fixed monthly cost — and helps you stay on the right side of the law.
What is landlord boiler cover?
Landlord boiler cover is an annual policy that pays for repairs (and often the annual gas safety inspection) on the boiler and central heating system in a property you rent out. It usually includes a 24/7 call-out line, parts and labour up to a claim limit, and a Gas Safe registered engineer.
Your legal duties as a UK landlord in 2026
1. Annual Gas Safety Check (CP12 / LGSR)
Under the Gas Safety (Installation and Use) Regulations 1998, every gas appliance in a rented property must be inspected every 12 months by a Gas Safe registered engineer. You must give the tenant a copy of the CP12 (Landlord Gas Safety Record) within 28 days.
2. Keep the boiler in working order
Section 11 of the Landlord and Tenant Act 1985 requires you to keep the installations for heating and hot water in repair and proper working order. A broken boiler in winter is almost always classed as an urgent repair.
3. Carbon monoxide alarms
Since 2022, a CO alarm is required in every room with a fixed combustion appliance (excluding gas cookers). Cover policies do not replace this — but a good annual service will test it.
What should landlord boiler cover include?
- Annual gas safety inspection (CP12) — the single most valuable inclusion.
- Boiler and controls repair — pump, PCB, fan, diverter valve, thermostat.
- Central heating cover — radiators, pipework, motorised valves.
- 24/7 emergency call-out — tenants can report faults directly.
- No claim limits or realistic ones — watch for £500 caps that vanish after one repair.
- Gas Safe engineers — non-negotiable.
How much does landlord boiler cover cost in 2026?
Typical UK pricing sits between £15 and £30 per month per property depending on boiler age, excess and whether the CP12 is bundled. Standalone CP12 certificates alone cost £60–£120, so bundled cover is usually cheaper than paying separately.
Boiler age limits — the small print that catches landlords out
Most providers will not cover a boiler over 15 years old, and some restrict cover on boilers over 7 years. If your rental has an ageing boiler, get it assessed before you buy a policy — a replacement quote may be more sensible than repeated repairs.
Landlord cover vs. homeowner cover — what's different?
- Landlord policies include the annual CP12 automatically.
- Repairs are prioritised — tenants get faster response SLAs.
- Certificates and job reports are sent to you, not just the tenant.
- Multiple properties can usually be managed under one account.
How to choose the right policy
- Confirm the CP12 is included, not an add-on.
- Check the boiler age limit against your appliance.
- Read the excess — £60 is standard, £95+ is expensive per call-out.
- Look for unlimited call-outs, not a capped number per year.
- Make sure the provider uses Gas Safe engineers, not sub-contractors of unknown status.
