Landlord gas safety certificate cost and what's included
A landlord gas safety certificate, often called a CP12, is a legal requirement for any rented property with gas appliances, and it needs renewing every 12 months without exception. The cost is relatively modest compared to the consequences of letting it lapse.
Practical notes on a landlord gas safety certificate
- Single appliance certificate typically costs £60 to £80 in 2026
- Properties with boiler, fire and cooker together typically cost £75 to £95
- Certificates are valid for exactly 12 months and must be renewed on time
- A copy must be given to tenants within 28 days of the check, or before a new tenancy starts
- Staggering renewal dates across a portfolio helps spread cost and admin
Who should undertake the work
- Gas appliance work must be completed by a suitably qualified Gas Safe engineer
- Oil appliance work should be completed by a suitably qualified OFTEC technician
- Jamie Crawford Heating states both Gas Safe and OFTEC registration
Understanding a landlord gas safety certificate before you spend money
In 2026, a single gas appliance check for a landlord certificate typically costs £60 to £80, rising to around £75 to £95 where a boiler, gas fire and gas cooker are all present at the same property. The engineer checks each gas appliance for safe operation, tests for gas soundness, checks ventilation and flue arrangements, and confirms appliances are suitable for their location, issuing a certificate valid for 12 months from the inspection date. Portfolio landlords managing several properties across Bath, Radstock, Frome or the surrounding villages often arrange staggered renewal dates so certificates don't all fall due in the same month, which spreads both cost and admin through the year.

Questions we get asked
- What happens if a certificate lapses?
- Letting a property without a valid certificate is a legal breach with potential enforcement action, so renewal should be booked before the expiry date, not after.
- Do I need a new certificate for a new tenant?
- If the last certificate is still within its 12 month validity, it can normally be carried over, but a copy must be given to the incoming tenant.
- Can boiler servicing be done at the same visit?
- Often yes, and it can be more cost-effective to combine a service and the certificate check on the same call-out.
- Does this cover electrical safety too?
- No, a gas safety certificate only covers gas appliances; electrical safety checks are a separate legal requirement with their own certificate.
