PG Light-Switch

Are Your Electrical Fittings the Right Height?


All wall mounted switches and socket outlets should be built-in at the required heights.


In new dwellings only, switches and socket-outlets for lighting and other equipment should be between 450mm and 1200mm from finished floor level.

Consumer units should be mounted so that the switches are between 1350mm and 1450mm above floor level. At this height, the consumer unit is out of reach of young children yet accessible to other people when standing or sitting.


For switches and socket outlets, these are specified by Approved Document M which supports Part M of the Building Regulations (England and Wales).

Approved Document M does not recommend a height for new consumer units but the suggested measurements given in the details section will ensure you comply with Part M.

Additionally, door bells, entry phones, TV sockets and telephone jack points should be installed in accessible positions as indicated in the Approved Document M.


To make them accessible for people whose reach is limited and to help facilitate independent living for all people with disabilities.
