Like for like requirements

Jimi

Hi, I know like for like replacement is classed as maintenance and a MEIWC isn't required. With an alteration to a circuit the new work has to comply with the latest BS7671, so some of the existing installation will need to comply also to allow the new work to comply, like RCD (if required), bonding, existing equipment rating and condition etc.

Am I right in thinking that for like for like this is not required? So if there was no bonding or RCD protection you could still change a light fitting for example.

What if there was no CPC at the light and you were fitting a class 1 or class 2 fitting? Or getting crazy, no CPC on a socket front change?

Thanks.

    I have wasted a lot of time with potential customers in the past who have refused a consumer unit upgrade when wanting additional circuits and alterations made to their electrical installations because they are having a new kitchen installed or similar work.

    I have learnt to be blunt and walk away, the absolute classic was the guy who was spending thousands of pounds having his garden landscaped and wanted lighting and power including in and around a huge pond and water feature.

    He had a Wylex BS3036 fuse board in the external meter cabinet without any RCD protection and with the shower circuit dogged into the incoming terminals of the main switch, so the shower circuit was not isolated by the installation main switch and was only protected by the DNO main fuse.

    I said he needed a new consumer unit, he said he didn't want to pay for one and I left.

    What's not so easy is if initially things look okay, then turn out to be very nasty when you start taking them apart, such as finding out parts of a lighting circuit are not fit for purpose after you have started work.

    Yeah I'd always ensure full compliance with any addition or a new circuit. Just trying to get clarification on like for like. NICEIC technical seems to think minor works isn't necessary.
