Taken all labels off mine at home as when it was built someone stuck in right in the middle of the downstairs hallway wall.

All pretty pointless, never heard of any home owner or school caretaker Test a RCD, only a electrician should be working in it do duel colour is pointless, 230v isn't needed and next test date isn't needed on the CU as only needed at the origin.
 
The db would be fully labelled as required if it was for assessment by a scheme so don't see the difference but hey ho each to their own I guess.
 
They often fail to meet the required times when testing for an EICR or alteration/addition job due to not being operated for years, but after a couple of 'trips' they're generally fine again .
 
Really.........................................?

I simply don't agree.
Well surely it stands to reason that at the time of the change most Electricians would have been aware of it, but say in 20 or 30 years time many of the new breed will never have been come across red/yellow/blue and black cables.

Next the IET will be getting us to code all red and black cables C3!
only if they're wrong way round. :p

But if they are competent sparks the would check that the "odd" red cables are live, and the black ones neutral.

I still have some red sleeving left and use it on unmarked black switch wires whenever I come across them, it's annoying to find brown sleeve on both red and black on older wiring inside switches imo. :)

It's not as straightforward with a three-phase installation though where blue could be either L3 or neutral and black could be either L2 or neutral. It doesn't seem entirely unreasonable to warn people to verify what the conductors actually are.
