PR-03Turn off the power before loosening any switch or socket faceplateIf you need to paint behind a light switch or socket, turn the electricity off at the consumer unit first — the switch itself doesn't make the terminals inside safe to touch. Undo the two screws, ease the faceplate forward off the wall, and tape it clear rather than disconnecting any wires. Screw it back on and restore the power once that area is dry. If you're not confident doing this, leave faceplates in place and mask carefully round them instead.
