Landlords’ Gas Safety Certificate – CP12

According to The Gas Safety (Installation and Use) Regulations 1998, by law, every rented property in the UK requires annual gas safety checks to be carried out and presented with a Gas Safety Certificate (CP12) which lists the checks completed in the inspection. Checks must be carried out by a Gas Safe registered engineer, in order to receive a legal certificate.

When tenants move in, they will need to be provided with a copy and keep hold of old certificates (CP12s) as they need to be kept for at least two years. To keep your tenants safe, it is important to let them know where the mains are and how to turn the gas off and what to do if there was an emergency.

  • Check that all appliances are well ventilated
  • Check that all safety devices work effectively
  • Check the appliances and installation for gas tightness
  • Check the working and standing gas pressure
  • Declare any appliances unsafe if faults are detected
  • Make sure gas appliances are not being misused

What happens if you don’t have a gas safety certificate?

Not upholding a gas safety certificate is a serious offence and without it, a property cannot be let out to tenants. Landlords must get a gas safety check carried out annually and obtain certificates for at least two years.

How long does a gas certificate last?

A CP12 is valid for 12 months, after which a landlord must get another annual safety check carried out by a Gas Safe registered engineer.
