What is a CP12?
A CP12 (also known as a Landlord Gas Safety Record) is the official certificate issued after a Gas Safe registered engineer has inspected all gas appliances, pipework, and flues in your rental property. Under the Gas Safety (Installation and Use) Regulations 1998, every landlord in England and Wales is legally required to have a CP12 carried out every 12 months. There are no exceptions.
Failure to hold a valid certificate can result in fines of up to £6,000 per property and in serious cases, criminal prosecution.
At Swansea Gas & Oil, we make the process simple, fast, and stress-free. We liaise directly with your tenant to arrange access, so you don't have to.

Every CP12 inspection carried out by Swansea Gas and Oil includes:
- Visual inspection of all gas appliances (boiler, gas fire, gas hob, etc)
- Flue flow test ensuring harmful gases including carbon monoxide are safely expelled
- Full gas tightness test - checking for any leaks in pipework and connections
- Emergency control valve check
- Safety device testing - all controls and cut-off devices checked and operational
- Equipotential earth bonding verification
- Ventilation checks confirming adequate airflow to all appliances
As a private landlord or letting agent in South Wales, here is what the law requires you to do:

- Provide a copy of the certificate to your existing tenants within 28 days of the inspection
- Provide a copy to any new tenant before they move in
- Keep copies of all certificates for a minimum of two years
These rules apply to all residential rental properties with gas appliances - houses, flats, HMOs, and holiday lets.
