Anyone fill the gavity where the tails enter

[scooterboy]

Hi all, I had my assessment the other day and shown him a job with a replacement board. The tails ran up in the cavity wall from the meter box below on the outside of the house and in from the back of the cu, he said that I should seal the hole in the wall where the tails come through into the cu and inside the meter box where they enter the cavity. I've looked through the regs book and can't find it any where, thanks in advance, scooterboy

Surely that should be a Scotish joke?
