Official Landlord Gas Safety Certificate (CP12) – Up to 2 Domestic Appliances
Under the Gas Safety (Installation and Use) Regulations 1998, UK landlords are legally required to have an annual gas safety inspection conducted on all rental properties with gas appliances. Our accredited Gas Safe registered engineers carry out rigorous safety checks on up to 2 domestic gas appliances (such as your central heating boiler and gas cooker or hob) to ensure complete tenant safety and statutory compliance.
What Is Checked During the Gas Safety Inspection?
- Gas Tightness & Meter Test: Full system pressure drop test to confirm zero gas leaks across pipework.
- Burner Pressure & Gas Flow Rate: Verification that appliances operate at manufacturer-specified heat input and pressure.
- Flue Flow & Spillage Testing: Confirmation that combustion fumes and carbon monoxide exhaust safely outside without backdraft.
- Flame Failure Safety Devices: Testing automatic shut-off mechanisms on boilers, cookers, and hobs.
- Ventilation & Air Supply: Inspection of adequate permanent air vents and room ventilation clearances.
Legal Requirements & Penalties for UK Landlords
Landlords must provide a copy of the valid CP12 certificate to existing tenants within 28 days of the inspection, and to new tenants before they move in. Operating without a valid Gas Safety Certificate carries severe penalties, including fines of up to £6,000 per breach, invalidation of building insurance, and disqualification from serving Section 8 possession notices under the Renters’ Rights legislation.
