How to fit and replace electrical sockets

To fit and replace electric sockets in the UK, follow these general steps:

1. Safety first
   Turn off the power to the socket at the consumer unit (fuse box) before starting any work. Use a voltage tester to ensure the socket is not live.
   
   
2. Gather materials
   Purchase a new socket that matches the specifications of the existing one. You'll also need a screwdriver, wire cutters/strippers, and possibly a voltage tester.
   
   
3. Remove the old socket
   Unscrew the faceplate of the socket and carefully pull it away from the wall. You should see the wiring connected to terminals on the back.
   
   
4. Disconnect wiring
   Note the arrangement of wires before disconnecting them. There should be live (brown), neutral (blue), and earth (green/yellow) wires. Loosen the terminal screws and remove the wires.
   
   
5. Prepare the new socket
   If necessary, trim the ends of the wires to ensure they're clean and straight. Double-check the wiring layout on the new socket to match the old one.
   
   
6. Connect wiring to new socket
   Attach the live wire (brown) to the terminal marked "L", the neutral wire (blue) to the terminal marked "N", and the earth wire (green/yellow) to the terminal marked "E". Tighten the screws securely.
   
   
7. Secure the socket
   Carefully tuck the wiring back into the wall box, ensuring it doesn't get pinched or trapped. Align the new socket with the wall box and screw it into place.
   
   
8. Test the socket
   Once the socket is securely fitted, restore power at the consumer unit. Use a voltage tester to check that the socket is receiving power correctly.
   
   
9. Replace faceplate
   Finally, attach the faceplate of the new socket by aligning it with the base and tightening the screws. Make sure it sits flush against the wall.
   
   
10. Safety check
    Perform a final check to ensure everything is secure and working properly. Test the socket with a device to verify functionality.

If you're unsure about any aspect of fitting or replacing electric sockets, it's best to consult a qualified electrician for assistance. Safety should always be the top priority when working with electricity.
