There is a distinction so far as electrical safety is concerned between the fixed installations (i.e. wiring circuits, switches, sockets, light fittings and circuit boards on the one hand and appliances which can be plugged in and which will often be portable (e.g. refrigerators, electric cookers, kettles, toasters etc on the other).
With rented residential accommodation it is the Landlord's responsibility to ensure that the electrical installation and appliances provided by the landlord are safe when the tenancy begins and are in proper working order throughout the tenancy. At the start of the tenancy and throughout both must be free of risk of injury to tenants and residents. The local authority can take action to enforce electrical safety in residential accommodation under the Housing Health and Safety Rating System (HHSRS).
Landlords must have an EICR carried out every five years or on the start of a new tenancy.
