Well give the lady some credit, she came up with the circuit schedules fast enough, which would proberly surprise some people, myself included
"She" has been on here before and there has been trouble.
Its the row to the right of the tick that says Maximum measured Earth fault Loop Impedance

Why is the there a line of LIM on the L/N column?
Surely this is unacceptable on a c/u change?

Depends on the circuits.
For lighting circuits, if there are downlights or other fittings with 12v transformers, electronic ballasts or similar, it would be unreasonable to test LN, as this would involve dismantling most of the circuit first.
For socket circuits where items could easily be unplugged or FCUs switched off, there is no reason not to.
For the cooker circuit and the kitchen circuit which only supplies 1 outlet - presumably they couldn't be bothered.

Nor could they be bothered to disconnect neutrals before IR testing to earth. And, efli results don't matter as its on a 30ma rcd which in theory would allow up to 1667 ohms.
An RCD is not medicine for a poorly EFLI.
On a TT system there's little you can do about it, but on a TN one you do not let a high reading go by, saying "oh well, there's an RCD...."

Or replace the B6 with a B32, run a cable to a 5A FCU next to the CU.
Sorry - missed that.
