Look out!
Old style sockets and switches can be a sign that your electrics have not been checked for a long time. Homeowners should have the electrical installation checked by a registered electrician every 10 years, or when you move house. It is recommended that privately rented properties are checked every 5 years, or on change of tenancy.
Check out the Good Home Lincs information on Electrical Safety to find out more about electrical safety at home or find a registered electrician.
