A Landlord Gas Safety Certificate, or CP12, is an official document that confirms all gas appliances, fittings, and flues within a rental property have been checked by a Gas Safe registered engineer and are safe to use. The certificate, formally called a Landlord Gas Safety Record, provides details of the inspection and any safety issues identified. It's a key part of a landlord's legal duties to ensure tenant safety.

As a landlord, you are legally required to ensure all gas equipment in your property is safely installed and maintained. An annual gas safety inspection, resulting in a CP12 certificate, demonstrates you've taken steps to protect your tenants from potential gas-related dangers like leaks, fires, explosions, and carbon monoxide poisoning. It's about keeping your property safe and meeting your legal obligations.

A gas safety inspection needs to be carried out every 12 months by a Gas Safe registered engineer. You must keep copies of the certificate and provide one to your existing tenants within 28 days of the inspection, and to new tenants before they move in.

Only an engineer who is registered with the Gas Safe Register can legally carry out a gas safety inspection and issue a CP12 certificate. Always ask to see their Gas Safe ID card. Our engineers at Response Boiler Repair Liverpool are all Gas Safe registered and fully qualified to perform these checks.

The inspection covers all gas appliances owned by the landlord and installed in the property. This typically includes gas boilers, gas fires, gas cookers or hobs, and gas water heaters. The engineer will also check the gas pipework and flues.

During the inspection, our Gas Safe registered engineer will:

• Check the gas tightness of the installation.
• Check the standing and working pressure at the meter.
• Check each appliance for safe operation, including burner pressure and gas rate against manufacturer’s details.
• Ensure adequate ventilation is present for appliances.
• Test flue flow to ensure removal of combustion products.
• Check that all safety devices are working correctly (e.g., flame failure devices).
• Visually inspect pipework and other gas fittings.
• Carry out carbon monoxide testing where appropriate.
  Everything checked will be detailed on the Gas Safety Record.

The Gas Safety Certificate (CP12) is valid for 12 months from the date of the inspection. As the landlord, you are required to keep a copy of the certificate for at least two years. You must also provide a copy to your current tenants within 28 days of the inspection and to new tenants at the start of their tenancy.

The CP12 certificate is a detailed document. It will include:

• The address of the property where the inspection was carried out.
• The name and address of the landlord (or letting agent).
• The date of the inspection.
• Details of the Gas Safe registered engineer who carried out the inspection, including their registration number.
• A description and location of each appliance and flue checked.
• Any safety defects identified and the action taken or required.
• The results of all operational safety checks performed on the appliances.
• A statement confirming the installation is safe, or if not, what remedial work is needed.

If the Gas Safe engineer finds any issues that make an appliance or installation unsafe, they will advise you immediately. They may need to disconnect the unsafe appliance to ensure safety. The certificate will detail any defects and the remedial work required. It's your responsibility as the landlord to get any necessary repairs carried out promptly by a Gas Safe registered engineer to make the property safe.
