How to guides
Although you can increase the number of sockets in a room by converting single sockets to doubles, there may be times when you need an extra socket where none exist already. In this case, you'll need to add a spur from a ring circuit. You can either run this from an existing socket, or from a junction box that's connected into the cable run of a suitable ring circuit. The circuit must have RCD protection.
