Lighting and socket work covers a wide range of tasks, from replacing a single light fitting to running a new circuit for a home office or outbuilding. A qualified electrician is needed for any work that involves connecting to the fixed wiring, adding new cables or outlets, or altering existing circuits.
Socket installation can include upgrading single sockets to double outlets, adding USB-equipped sockets, installing additional outlets in rooms where demand has increased, or running a new circuit to serve a defined area of the property. In rooms that contain a bath or shower, BS 7671 sets out requirements for the location and type of electrical accessories, including sockets.
These requirements take into account the position of the accessory relative to the bath or shower and the level of protection provided. A qualified electrician will assess the specific room layout to determine what is and is not permitted at each location, rather than applying a blanket restriction to the whole room.
Lighting work includes replacing existing fittings, upgrading to LED, installing recessed downlights, adding dimmer circuits, or fitting external lighting. Where recessed downlights are installed in a ceiling that separates two floors, or provides fire separation between spaces, fittings with fire protection should be specified to maintain the fire resistance of the ceiling.
The electrician will assess the ceiling construction and specify fittings appropriate to it. Fault symptoms associated with lighting and socket circuits include flickering or intermittent lights, sockets that are warm to the touch, visible scorch marks around outlet faceplates, circuit breakers that trip when a particular socket or light is used, and outlets where no power is present despite the relevant breaker being in the on position.
These symptoms can indicate loose connections, a fault in the circuit wiring or an overloaded circuit, and should be investigated by a qualified electrician.
