Summary: Wiring an exterior wall light: Learn how to wire an exterior wall light, prepare a new lighting circuit, fit a boxed light fitting, fit a bracketed light fitting, install an inside switch, and fit an outside switch.
This is a non-notifiable project providing the spur is not run from a circuit in a kitchen or special location. Installation must conform to Electrical Regulations.
The safest way to install a wall light is to run a spur from the indoor lighting circuit. It is also possible to run the spur from a socket outlet on the ring-main via an FCU. The switch should be placed on the inside of the wall and you will need weatherproof light fittings designed for mounting on an outdoor wall.
