Landlord Gas Safety Certificates (CP12) in Cardiff: What You Must Do

If you rent out property in Cardiff, an annual gas safety check isn't optional. Here's what the certificate covers and how to stay compliant without any drama.

What the law requires Every gas appliance, fitting and flue in a rented property must be checked for safety every 12 months by a Gas Safe registered engineer. You must keep records for two years and give a copy of the certificate to existing tenants within 28 days, and to new tenants before they move in. Under the Renting Homes (Wales) Act, a property without a valid certificate can be treated as unfit for human habitation.

What we check on a CP12 - Gas tightness of the installation - Burner pressure and gas rate against manufacturer data - Flue flow and spillage tests - Ventilation and air supply - Safety devices and appliance stability

Common failures in Cardiff rentals Blocked flue terminals behind extensions, missing ventilation after a room has been sealed up, and old back boilers left in unused fireplaces are the three we see most. Sealed-off appliances still need to be capped correctly and recorded.

Service vs. safety check A gas safety check is not a boiler service. The check confirms the appliance is safe; the service keeps it reliable and protects the manufacturer warranty. Booking both together in one visit is cheaper and keeps tenants happy.
