  • I want to replace the wall lights in the house.

    Is it a case of take photo of wiring
    Turn off electrics
    Undo wires
    Wire new lamp according to photo
    Turn on electrics

    I don’t have a volt pen or similar to check the electricity has deffo gone off - should I before attempting? There’s 10 to do so it would be a saving if I can do it myself

  • I find it's generally more like

    Is it a case of take photo of wiring
    Turn off electrics
    Undo wires
    Discover new light has different terminals to old light
    Wire new lamp according to what you hope is right
    Turn on electrics

    Obviously I'd also turn off electrics before opening it up to take a photo.

    In my experience it's sometimes easy, sometimes a sod with random wires, different terminals, a new fitting that doesn't line up, etc. Particularly so if it's an old property with a variety of bodges.

    Also, if you're not able to test whether the electric is off I'd be tempted to turn the electrics off fully rather than assuming that all the lights are on the correctly marked switch at the consumer unit.

  • Confirm the power is off by leaving the lights on when you turn the circuit breaker off.

    Or just get a volt pen - a decent fluke one is <£20.

  • If you use wagos to make the connections it can save some time. You should invest in a voltage tester if you're planning on doing small electrical works for the rest of your life. The wand style are not as useful and safe as the normal voltage tester like the Martindale VT12. They are around the £30 mark but very useful and could save your life.
