landlord's annual gas safety check involves a Gas Safe Registered engineer inspecting the property's gas appliances, pipework, and flues to ensure they are safe, operating correctly, and not causing a risk of carbon monoxide poisoning or explosion. The service includes visual checks, pressure tests, flue tests, and an inspection of safety devices and ventilation, culminating in the issuance of a Gas Safety Certificate, which acts as formal proof of the check. 

What the Gas Safe Engineer Does

• Visual Inspection:

  The engineer performs a thorough visual check of the gas meter, pipework, and any gas appliances (like the boiler, hob, oven, or water heater) provided by the landlord. 

• Safety Device Check:

  All safety features and devices on the appliances are tested to ensure they are functioning correctly. 

• Pressure and Burner Test:

  The engineer checks that the appliances are operating at the correct gas pressure and that the burners are functioning properly. 

• Flue and Ventilation Checks:

  The engineer verifies that the flues, chimneys, and air supply are clear and adequate, allowing fumes to safely discharge and preventing the build-up of dangerous gases. 

• Leak Testing:

  A gas tightness test is carried out at the gas meter to confirm there are no gas leaks in the installation. 

• Defect Identification:

  Any defects or signs of wear are identified and documented in the safety certificate. 

The Outcome

• Gas Safety Certificate:

  After the inspection, the engineer issues a formal Gas Safety Certificate, detailing the appliances checked, the results of the tests, and any identified safety defects. 

• Rectification of Defects:

  If any gas safety defects are found, they must be rectified by a Gas Safe registered engineer before the appliance can be used again. 

• Landlord's Records:

  Landlords must provide a copy of the latest gas safety certificate to existing tenants and new tenants before they move in.
