Gas Safety Certificate: Requirements for UK Landlords
Landlords must have gas appliances inspected annually by a Gas Safe registered engineer and provide tenants with a copy of the certificate. Non-compliance is a criminal offence.
What is a Gas Safety Certificate?
A Gas Safety Certificate, also known as a CP12 or Landlord Gas Safety Record, is a document issued after a Gas Safe registered engineer has inspected all gas appliances, fittings, and flues in a rental property. The certificate confirms that the gas installation is safe to use.
The requirement is set out in the Gas Safety (Installation and Use) Regulations 1998. These regulations apply to all landlords in England, Scotland, and Wales who rent out properties with gas appliances.
Annual inspection requirements
Gas safety checks must be carried out every 12 months. The check must be completed before the anniversary of the previous certificate expires. For example, if your last check was on 15 January 2025, the next one must be done by 14 January 2026.
The inspection covers boilers and water heaters, gas fires and radiators, gas cookers and hobs, any other gas appliances, and all pipework and flues. Only a Gas Safe registered engineer can carry out the inspection. You can verify an engineer's registration on the Gas Safe Register website.
When must you provide the certificate?
For new tenants, you must provide a copy of the current Gas Safety Certificate before they move in. For existing tenants, you must provide a copy within 28 days of the annual check.
The certificate can be provided as a paper copy, by email, or through a document sharing platform. The key is that you must be able to demonstrate the tenant received it.
Penalties for non-compliance
Failure to comply is a criminal offence. Penalties include an unlimited fine and up to 6 months imprisonment in serious cases.
Legal implications
You must provide the tenant with a copy of the current Gas Safety Certificate. If your certificate has lapsed or you failed to provide a copy, your legal position in any dispute is significantly weakened.
To remedy the situation, you must arrange a new gas safety inspection if the current certificate has expired, then provide the tenant with a copy of the valid certificate.
How to prove your tenant received it
In a dispute, you may need to prove that you provided the certificate to your tenant. Options include having the tenant sign a receipt acknowledging they received it, including a clause in the tenancy agreement confirming receipt, using a document platform that tracks when the certificate was accessed, or sending by recorded delivery (though this only proves delivery, not that it was read).
How HouseFile helps
Upload your Gas Safety Certificate to HouseFile and share it with tenants through a secure link. The platform records when your tenant first accessed the certificate, tenant acknowledgement with a timestamp, and maintains a clear audit trail for each tenancy.
