The finer details of a CP12 gas safety certificate

Gas safety should be a top priority all year round, but Gas Safety Week – a campaign coordinated by Gas Safe Register – aims to highlight the dangers of inadequate checks and raise awareness around how to stay safe. In 2020, Gas Safety Week is running from 14 – 20 September.

A gas safety certificate, also known as a CP12 certificate, is central to safety measures.

What is it?

Under the Gas Safety (Installation and Use) Regulations 1998, you’re legally required to get a gas safety certificate every year for any properties you let out. This will be provided by a Gas Safe registered engineer after completing a mandatory gas safety check.

You must provide existing tenants with a copy within 28 days of the check being carried out, and give the most up to date certificate to new tenants at the beginning of their lease. While you’re only legally required to have checks done every 12 months, it’s a good idea to have appliances checked between tenants while the property is vacant.

The Health and Safety Executive (HSE) also recommends installing a carbon monoxide (CO) alarm to make sure your tenants are safe from the dangers of carbon monoxide poisoning.

What’s included?

The gas safety certificate is issued following mandatory gas safety checks, where a Gas Safe registered engineer will carry out the following work:

  • Checking gas appliances for gas tightness
  • Testing standing and working pressure on test points, if available
  • Checking burner pressure and gas rate against the manufacturer’s data plate
  • Checking for all necessary ventilation
  • Testing the flue flow to make sure combustible products are removed
  • Checking all flame failure devices are operating satisfactorily
  • Checking for physical stability, presence and effectiveness of stability brackets where appropriate.

The engineer will also investigate and report on any evidence of unsafe operation.

Once this work has been carried out, you will be issued a gas safety certificate which will be valid for one year.

Sometimes tenants refuse to allow the Gas Safe engineer access to carry out the necessary checks. If this happens to you, follow our steps on How to gain access for a landlord gas inspection.
