Gas safety checks should cover all relevant gas-burning appliances and their associated parts, including boilers, ovens, pipework, flues and chimneys. These inspections ensure that appliances are functioning correctly, burning gas safely, have appropriate ventilation and adequate air supply, and that safety devices are operational. Once the inspection has been carried out and the certificate issued, the record will contain: • the name, Gas Safe ID number and signature of the registered engineer; • the date of the gas safety inspection; • the name and address of the landlord or letting agent; • the address of the inspected property; • information about each gas appliance and flue checked; • details of any identified faults and required remedial action; and • confirmation that the inspection complies with statutory requirements and the date of the next scheduled check (usually 12 months after the inspection)."Example Landlord Gas Safety Certificate".
