One must consider the number of electrical appliances in the modern home when deciding on the number of socket-outlets per room and whether they should be single or double socket outlets or combinations of Euro style outlets to minimize the need for adaptors and extension cords. Socket outlets should be carefully positioned in places where they are most needed; where there are only two sockets in a room, they should preferably be placed on opposite walls. Diﬀerent fixing heights may be preferred in some situations, but, although not yet standard practice in the industry, it is suggested that no socket outlet should be lower than 300 mm above finished floor level.
The preferred height for socket outlets over worktops is approximately 1100mm above floor level but is also dependent on the kitchen design and layout.
