Step-by-Step Guide to Wiring a UK Plug Socket

Step 1: Safety First

Turn Off the Power: This is crucial. Switch off the mains power at the consumer unit/fuse box. Confirm the power is off using a voltage tester.

Step 2: Prepare the Socket

Remove the Faceplate: Unscrew the faceplate from the existing socket or the new mounting box you've installed. Take a moment to familiarize yourself with the wiring layout.

Step 3: Strip the Wires

Strip and Prepare: Use your wire strippers to carefully strip about 1.5cm of insulation from the ends of each wire (live, neutral, and earth).

If you are removing or swapping out your old plug socket for a new one, the wires should already be stripped. Just make sure that you cut off any damaged, loose or frayed wire. Cut back/ strip the insulation as needed.

Step 4: Attach the Wires

Secure the Connections: Connect the wires to their corresponding terminals on the back of the socket:

Live (Brown/Red) wire to the L (Live) terminal.
Neutral (Blue/Black) wire to the N (Neutral) terminal.
Earth (Green and Yellow/Bare) wire to the E (Earth) terminal.

Make sure the connections are tight and secure.

Step 5: Reattach the Faceplate

Once all the wires are connected, gently push them into the mounting box and screw the faceplate back on.

Step 6: Restore Power and Test

Turn the power back on at the consumer unit and test the socket with a plugin appliance or a socket tester.
