A gas safety certificate, also known as a CP12 or Landlord Gas Safety Record, confirms that gas appliances and installations in a property have been checked and found safe by a Gas Safe registered engineer.

A CP12 is the official document issued after a gas safety inspection, recording appliance condition, safety test results, and any defects or remedial actions required.
