These new Regulations require landlords to have the electrical installations in their properties inspected and tested by a person who is qualified and competent, at least every 5 years. Landlords must provide a copy of the electrical safety report to their tenants. There are several best practices you can do as a landlord or business owner to ensure that electrical appliances in your property do not cause harm to your tenants or employees. Firstly, check all appliances before the start of a new tenancy, and then every two years for smaller appliances such as kettles, microwaves, toasters, lamps and fans, and every four years for larger pieces of electrical equipment such as fridges, ovens, dishwashers and washing machines.
