Gas Safety
What Is a CP12 Landlord Gas Safety Certificate?
By TRIDS Gas & Plumbing• 22 September 2026
A plain-English guide to the annual gas safety record every UK landlord must hold.
A CP12 records that every gas appliance and flue in a rented property has been checked by a Gas Safe engineer. Landlords must keep records and give tenants a copy. TRIDS issues digital certificates after the visit.
🚨 UK GAS EMERGENCY ADVICE
If you smell gas or suspect a carbon monoxide leak, turn off your gas supply at the meter immediately and call the National Gas Emergency Service on 0800 111 999.
