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.

    This country is awash with documentation. We should strive to reduce that burden where possible. Like for like replacement seems like one of those areas that doesn’t need paperwork unless something needs to be communicated to the client. It would seem reasonable that the responsibility for the safety of such work should be left squarely with the person doing the replacing, who, in my view, should be a competent electrician. A competent electrician would not replace a socket if there was no earth or fit a replacement class 1 luminaire to a circuit with no cpc. Lack of RCD or protective bonding etc will require a judgement call and in such cases recording that communication might be prudent. A competent electrician should also be able to determine the amount of testing that might be necessary and should note the results in their own day to day job records in much the same way as time and materials would be recorded.
