You've become a nation of label stickers for some reason. The last time i looked at a CU in the UK, you literary couldn't see the plastic on the front cover or it's sides!! If it had been my CU the bloody lot would have been removed... lol!!!
It's true Eng. The other week I was working on a CU, and between the 240v label, RCD test label, harmonised colours label, EICR next due label, circuit detail label, I had nowhere to stick my bogies.
