Gas Safety Certificates for Landlords in London What You Need to Know in 2025

As a landlord in London, obtaining a valid Gas Safety Certificate (also known as a CP12 certificate) is a legal requirement and a crucial responsibility to ensure tenant safety. This certificate confirms that all gas appliances, pipework, flues, and fittings in your rental property have been inspected and are safe to use.

What is a Gas Safety Certificate?

A Gas Safety Certificate is an official document issued by a Gas Safe registered engineer after a thorough inspection of all gas appliances in a property. This includes boilers, gas fires, cookers, pipework, chimneys, and flues. The inspection ensures that everything is operating safely, efficiently, and free from leaks or defects. For more details, see the Gas Safety Certificate page.

Legal Requirements for Landlords

Under the Gas Safety (Installation and Use) Regulations 1998, landlords must:

  • Arrange an annual gas safety check for every gas appliance and flue in their rental property.

  • Use only Gas Safe registered engineers to carry out inspections and any necessary repairs.

  • Provide tenants with a copy of the Gas Safety Certificate within 28 days of the inspection or before new tenants move in.

  • Keep records of all gas safety checks for at least two years.

Why is the Gas Safety Certificate Important?

  • It ensures the safety of tenants by confirming gas appliances are safe to use.

  • It keeps landlords compliant with legal obligations, helping avoid heavy fines or legal action.

  • Insurance claims related to gas incidents may be denied if a valid certificate is not held.

  • It protects landlords’ reputations and helps maintain tenant trust.
