Evening all

When doing a consumer unit change, how much dept do you all go into? Do you treat it like an EICR with 20% ish and spot checking?

Normally we do end to end, r1 or r2 and IR test once the old board is off and Zs when the new board is on. We try and find end of the line on each circuit and also spot checking.

Didnt know if there is an offical reg/ruling of how much you should do

This is a lazy answer but there’s too much to write....... have a look at the electrical safety first best practice guide for a replacement of a consumer unit.

as much as is necessary to ensure that the installation as a whole is safe and fit for purpose. and as little as a tight-arsed customer is willing to pay for. your EIC should cover everything .

Might not be a Reg, but there is a "Best Practice Guide" You might want to read it, before you take on any more CU swaps

I think this is a good question.

Imagine doing L-N IR tests for every circuit. That might be ok for immersions, cookers, shower etc but for socket circuits and lighting circuits you could spend half the day hunting down something left plugged in.
I tend to just do L/N-E IR tests for the EIC with regards a CU change.

Maybe a good question HHD but for someone charging people for EICRs it's somewhat disturbing that they haven't read the Guidance provided by the IET or more importantly the "Electrical Safety Council" What say you???????

I always did the testing as if it was new. Never charged for an EICR beforehand, but that was included in the price.

e.g that wasn't an add on.

I insist on a full EICR being done in advance of a board change and include the cost within the overall price. If the customer doesn't like the price, then fine, get someone else to do it.

I didn’t do EICR’s. But don’t think I would of got many jobs if I insisted on one before a replacement CU. Or are you saying you did some testing before taking the old one off the wall?

I do a full EICR before the board is removed from the wall.
