If you are in any doubt about working with electricity, seek professional advice from a qualified electrician. Any electrical work must comply with the Institution of Electrical Engineers (IEE) regulations (BS7671).
Always refer to and follow precisely the manufacturer's instructions when fitting a new socket.
Any electrical installation must comply with Building Regulations, specifically Part P, which came into effect on 1 January 2005, with the ammended version coming into effect on 6 April 2006. A further update came into force on 6 April 2013. Refer to these regulations before carrying out any electrical work (download at www.planningportal.gov.uk).
Replacing a socket is nonnotifiable under Part P, and therefore it is not necessary to have the work carried out by a qualified electrician, or to inform your local authority building inspector of the work, except in high-risk areas, or special locations, such as bathrooms. For a full list of these locations, refer to Part P. Part P strongly advises taking advice from a qualified electrician for carrying out any DIY electrical work. All electrical work must be tested and inspected.
This guide shows fitting a metal socket onto a plastic flush mounting box and the instructions shown overpage only relate to plastic mounting boxes. If you have metal mounting boxes, earthing requirements may vary, so refer to the manufacturer's guidelines.
If the socket you are changing has two earth terminals, this means that it has a dual earth facility, which is required if you need to comply with Regulation 607 of BS7671. As always, follow the manufacturer's guidelines and recommendations in such instances.
If you find earth wires are bare, you must sheathe them with some green and yellow sleeving.
Colours used in hard-wire installations (including cables supplying sockets) have changed in recent years. The table below shows the different colours for wires, prior to and after April 2004.
