Annual certificate to prove gas appliance working safely Landlords’ have a duty of care and are responsible for the safety of their Tenants when in their property. The Gas Safety (Installation and Use) Regulations 1998 is the governing legislation that deals with a Landlords’ duty to ensure that all gas appliances, fittings and flues provided for Tenants are safe. So, it is your responsibility as a Landlord to maintain and repair appliances, flues and pipework that you have provided for use by your Tenants and complete a annual Landlord Gas Safety Check. You must use a Gas Safe registered engineer to carry any work that is required, and this work should be carried out in a timely manner. An annual gas safety check is also required. This must be carried out within 12 months of the installation of a new appliance or flue and thereafter every year, again by a Gas Safe registered engineer. A gas safe certificate will be issued at the time and this needs to be kept for 2 years. A copy of the gas safe certificate needs to be given to the Tenant with 28 days of the check taking place and also as and when new Tenants move in. Landlords and Agents should also retain a copy on file, which can be in an electronic format, provided that it can be printed out legibly!
