    Plug Wire Colours In The UK

    Plug Wire Colours In The UK

    March 30, 2021

    In the UK, a properly wired electrical socket will have three different coloured wires. Brown is a live wire, blue indicates a neutral wire and yellow and green indicates earth. The earth (or ground) wire is an important safety feature as it stops the live wire from transporting the electrical current straight onto the casing of the appliance in the event of a problem.

    Before you attempt to open a plug socket or carry out any kind of minor electrical work in your home, you should be fully aware of what the colour of each wire in your plug socket means.

    Prior to 2006, electrical sockets had the following colours – red for a live wire, black for neutral and green and yellow for earth. It is now illegal for any sockets to show these wire colours if they have been installed after 2006. If your sockets feature the old wiring colours, you may want to consider having these updated.

    If your home has a mixture of new and old wiring, the electrician must place a warning n the socket in question to ensure that there is no confusion when carrying our further electrical work in the future.


    How Long Should Wires Last?


    When installed correctly, electrical wiring can last anywhere between 30 and 40 years. If your home is new, you probably don’t need to worry about the electrics. However, if you are moving into an old home, you may want to have the electrics tested or replaced before you move in.


    Positioning of Wires in a Socket


    The blue, neutral wire is always to the left on a UK plug, the brown wire is to the right and the yellow and green earth wire runs through the centre of the plug.


    What is PAT?

    Portable Appliance Testing (PAT) is the testing of electrical appliances that can be disconnected from its electrical supply or one that can be moved. It checks to see if the appliances are in good working order and are safe to use. Keeping these appliances in good working order is essential for landlords, business owners or managers of premises and should be conducted on a regular business.

    How do I know if I need a rewire?

    More common in older properties, signs you may need a rewire can be:

    - Shocks from switches and/or sockets

    - Fuses tripping

    - Damaged, worn or exposed cables
