To ensure your tenants’ safety, all gas appliances and flues need to undergo an annual gas safety check – and always by a Gas Safe registered engineer. Once this has been done, you’ll be given a Landlord Gas Safety Record or Gas Safety Certificate with details of all the checks that were carried out. It can also be referred to as a CP12 certificate. You can arrange for a gas safety check to be carried out any time from 10-12 months after the last check, without affecting the original check expiry date. If it’s less than 10 or more than 12 months after the last check, you’ll end up with a new deadline date – 12 months from the most recent check. Appliances owned by your tenants aren’t your responsibility – although it’s still up to you to ensure the safety of any connecting flues, unless they’re solely connected to the tenants’ appliance.
