By law, Landlords are required to ensure that their rental property, and any electrical equipment provided, is safe before a tenancy begins and throughout its duration.
An electrical installation comprises all the fixed electrical equipment that is supplied through the electricity meter. It includes the cables that are usually hidden in the walls and ceilings, accessories (such as sockets, switches and light fittings), and the consumer unit (fusebox) that contains all the fuses, circuit‑breakers and, preferably residual current devices (RCDs).
An Electrical Installation Certificate must be issued for all new electrical installations. It may also be required for an alteration or addition to the installation – depending upon whether or not a new circuit has been installed. Where an alteration or addition is carried out but does not include a new circuit, a MEIWC or an EIC may be used. A Domestic Electrical Installation Certificate is a form of EIC designed specifically for domestic electrical installations.
