Recommended checks before CU change

As most of you know I’ve only been qualified for just over a year and I’ve got a quote to do for a cu upgrade.


I know I’m nowhere experienced enough to do EICR’s yet, but what would you guys recommend I check/test before doing the cu upgrade and should I do these checks/tests at the quote stage?

    Thanks for all your replies guys, been very helpful.


    What would be a low enough IR reading to cause RCD’s to trip on a new board?


    The house in question is a four bedroom country house, so if I can avoid it, I’d rather not have to go around the whole place disconnecting everything, the residents are both in their late 60’s.  I didn’t see a circuit diagram on my initial visit either, so it could be a fun visit anyway.  I do need to find where their water & gas enters the property too, as I couldn’t see any bonding from the fuseboard and the lady wasn’t sure where they both were.
