Gas safety for landlords
Under the Gas Safety (Installation and Use) Regulations 1998, a landlord must keep the gas pipework, appliances and flues they provide in a safe condition and have each appliance and flue checked every 12 months by a Gas Safe registered engineer. Keep the record of each check for two years. Give a copy to existing tenants within 28 days of the check, and to new tenants before they move in.
