As a landlord in Central London, ensuring the safety of your tenants is paramount. One crucial aspect of this responsibility is obtaining and maintaining a valid Gas Safety Certificate, also known as a CP12. This document is not just a piece of paper; it’s a legal requirement that protects your tenants from the potentially devastating consequences of faulty gas appliances.

A Gas Safety Certificate (CP12) is a document issued by a Gas Safe registered engineer after a thorough inspection of all gas appliances in a rented property. This inspection confirms that the appliances are safe and functioning correctly. It covers:

  • Gas appliances: Boilers, cookers, gas fires, and other gas-powered devices.

  • Pipework: Ensuring gas pipes are free from leaks and in good condition.

  • Flues and ventilation: Checking that flues are properly venting combustion gases and adequate ventilation is present.

What is a Gas Safety Certificate (CP12)?
Why is a CP12 Important for Landlords?
  1. Legal Compliance: Landlords in the UK are legally required to have a Gas Safety Certificate for all rented properties. Failure to comply can result in hefty fines and even prosecution.

  2. Tenant Safety: Gas leaks, carbon monoxide poisoning, and explosions are serious hazards. A CP12 ensures your tenants are protected from these risks.

  3. Peace of Mind: Knowing your gas appliances are safe provides peace of mind for both you and your tenants.

  4. Insurance Requirements: Many landlord insurance policies require a valid CP12.

Key Requirements for Landlords:
  • Annual Inspections: A Gas Safety Certificate must be renewed annually.

  • Gas Safe Registered Engineer: Only a Gas Safe registered engineer can perform the inspection and issue the certificate.

  • Provide a Copy to Tenants: You must provide a copy of the CP12 to your tenants within 28 days of the inspection or to new tenants before they move in.

  • Keep Records: Maintain records of all Gas Safety Certificates for at least two years.

What Happens During a CP12 Inspection?

A Gas Safe registered engineer will:

  • Visually inspect all gas appliances.

  • Check for gas leaks.

  • Test the pressure of the gas supply.

  • Inspect flues and ventilation.
