From time to time, it may be necessary to change a plug on an electrical appliance in the UK. Whether the plug is damaged, the fuse has blown, or you simply need to swap out a non-UK plug for a British one, knowing how to change a plug safely and correctly is an essential skill. In this blog post, we will provide you with a step-by-step guide on how to change a UK plug, ensuring that you can confidently and safely perform this task.

Safety Precautions

Before you begin, it’s essential to take some safety precautions:

  1. Disconnect the appliance from the mains power supply.
  2. Ensure that your hands are dry and that you are not standing on a wet surface.
  3. Use insulated tools when working with electrical components.

What You Will Need

To change a UK plug, you will need the following items:

  1. A replacement UK plug
  2. A flat-head screwdriver
  3. A wire stripper or a sharp knife
  4. A Phillips head screwdriver (if required)

Step 1: Remove the Old Plug

Using a flat-head screwdriver, remove the screw that holds the plug cover in place. Carefully take off the plug cover and set it aside.

Step 2: Identify the Wires

Inside the plug, you will see three wires connected to three terminals. These wires should be color-coded as follows:

  1. Brown wire – Live (L)
  2. Blue wire – Neutral (N)
  3. Green and yellow striped wire – Earth (E)

Step 3: Disconnect the Wires

Loosen the screws on the terminals and gently remove the wires from their respective connections. If the plug has a cable grip, loosen it and remove the cable.

Step 4: Prepare the New Plug

Open up the new UK plug by removing the screw holding the cover in place. If the plug has a removable fuse carrier, take it out and insert the correct fuse for your appliance. The fuse rating should be specified in the appliance’s user manual or marked on the appliance itself.

Step 5: Strip the Wires

If necessary, strip about 1cm of insulation off the ends of the wires using a wire stripper or a sharp knife. Be careful not to damage the copper strands inside.

Step 6: Connect the Wires to the New Plug

Insert the stripped ends of the wires into their corresponding terminals in the new plug:

  1. Brown wire – Live (L)
  2. Blue wire – Neutral (N)
  3. Green and yellow striped wire – Earth (E)

Ensure that no stray strands of copper are sticking out and that the insulation reaches the terminal. Tighten the terminal screws to secure the wires in place.

Step 7: Secure the Cable Grip

If the plug has a cable grip, insert the cable into it and tighten the screws to hold the cable securely. This prevents the wires from being pulled out of the plug accidentally.

Step 8: Reassemble the Plug

Replace the plug cover and secure it with the screw. Ensure that the cover is correctly aligned and that all components are properly seated.

Step 9: Test the Appliance

Plug the appliance into a mains socket and test it to ensure that it is functioning correctly.


Changing a UK plug is a relatively simple task when you follow the correct steps and take appropriate safety precautions. By learning how to change a plug, you can save yourself time, money, and hassle, ensuring that your electrical appliances remain safe and functional.
