Like for like requirements

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 probably write out more Minor works Certificates than any other electrician using this forum.

    It takes a couple of minutes to write out an MWC but sets you apart from the bloke down the pub, I get a lot of work because I give customers an MWC, it also rectum protectum to quote another forum user as you are covering yourself by writing all the obvious non-compliances with the current edition of the Wiring Regulations in Part 1 and telling the customer what they are.

    Needless to say, the box in Part 1 on the model form is too small.

    There is a grey area though - it may have inadequate looking bonding and yet the Zs checks out OK,  it may well not have an RCD, there may be quite a lot of things that would be C3 or the old FI on an EICR, but that does not always have to stop the job.

    But you probably ought to note it, and your professional opinion that it will need improving, so that later no-one can say  'you said it was all OK when you changed the light fitting '  - you are only saying your new work is not making it worse,  you are not adopting or approving the stuff that  is already there, and is not yours. That needs to be made crystal clear to all involved.

    The time you may not bother is if records of who did what and lines of responsibility are organized another way - that may be the case if you are working on a large site with a traditional works services dept, clerk of works, master drawings etc, but only if that department has its own records in order, and a proper process for flagging up any problem encountered mid-job.
