CP12 Explained
What Is a Landlord Gas Safety Certificate?
A CP12, also called a landlord gas safety record, documents the annual safety check of relevant gas appliances and flues supplied within a rented property.
A clear annual record for your rental property
The inspection must be carried out by a Gas Safe registered engineer. The engineer checks the gas appliances and flues covered by the landlord's legal duties and records the required inspection information. Connected Gas & Heating operates under Gas Safe registration 186715 and provides CP12 appointments for individual landlords, portfolio landlords and letting agents across the North East.
Landlord Responsibilities
Your Legal Gas Safety Duties as a Landlord
Landlords must arrange regular gas safety checks and provide the resulting record to tenants. Keeping the inspection organised protects tenants and provides evidence that the legal duty has been addressed.
Renew Every 12 Months
A current gas safety record is normally valid for 12 months. The next inspection must be managed in time to keep the property's record current.
Give Tenants a Copy
Existing tenants must receive the record within 28 days of the check. New tenants must receive a current copy before they move into the property.
Retain Your Records
Landlords must keep gas safety check records for at least two years. Clear records make renewals and portfolio management easier to track.
The Inspection
What We Check During a CP12 Inspection
The engineer assesses the relevant gas installation and records the required safety information. Any defect found is explained clearly so appropriate action can be arranged.
- Gas appliances. Relevant landlord-provided appliances are inspected for safe operation and condition.
- Flues and combustion products. The engineer checks that flues are suitable and combustion products can be removed safely.
- Gas tightness and soundness. The installation is assessed for signs of unsafe leakage or deterioration.
- Ventilation provisions. Required ventilation is checked as part of the safe operation of applicable appliances.
- Safety devices and controls. Relevant safety features are checked to confirm that they operate correctly.
- Operating pressures. Appliance pressures and related measurements are checked where required during the inspection.

How long does a gas safety check take?
The appointment length depends on the number and type of gas appliances, the property layout and whether any defect requires further investigation. We can discuss the property details when arranging the inspection.

Failing to meet landlord gas safety duties is a breach of the Gas Safety (Installation and Use) Regulations 1998 and can lead to serious enforcement action and penalties. Landlords should arrange an overdue check promptly and address any identified defects.
