    Does a CU swap require a full initial verification on all circuits before it can be energised?

    To my understanding it would be ideal to test and inspect before energisation, but it isn't 100% necessary. If it leaves a client without power, it breaches health and safety (no power to safety services etc) or inconveniences them I'd have thought it would be reasonably practicable to turn on...

    Do LED lights require specific wiring?

    Just changed my outside light (100w bulb) with a security light with PIR fitted with a 1.5w integrated LED light and a 5w LED candle bulb. Can't get the new light to work. There is nothing wrong with the new light as I got it to work with a 3 pin plug. Any ideas anyone?

    When does an installation NEED an RCD? I thought that all new circuits need one but I now believe that I am mistaken. Regulation 411.3.3 for socket outlets up to 32amps and regulation 411.3.4 for lights. Then for special locations like bathrooms. If the cables are less than 50mm deep into the...

    Installation is in fair condition and to comply to current Regs would require a rewire/upgrade.

    The above statement was made in an EICR which I was asked to look at. In my opinion they are on the wrong side of Trading Standards to suggest that an installation should be re-wired because it is not up to current regulations. If it is safe then I would not suggest to a client they must have a...
