What is a landlord gas safety certificate (CP12)

A CP12 is the common name people use for a landlord gas safety certificate. It is issued after a Gas Safe registered engineer inspects relevant gas appliances and associated flues in a rental property and records the results on the Landlord Gas Safety Record.

The purpose is to confirm gas appliances and flues have been checked and to record any action required. If issues are found, we explain what is needed and provide clear next steps.

Validity: A landlord gas safety record is typically valid for 12 months, and landlords must provide a copy to existing tenants within 28 days and to new tenants before they move in.
