Andrew Betteridge:
I've confused myself.
The Minor works Certificates in the link above are the BS7671:2008 version.
I thought that we were going to be expected to use the draft version of BS7671:2018, but that version didn't make it into the final version of BS7671:2018.
So the new version requires more information, but not as much as I was expecting from having looked at the draft version, which wanted additional information including Zdb and the name of the manufacturer of the circuit protective device which would have highlighted the installation of devices that were not original consumer unit equipment manufacturers devices.

Philip Wood:
For additional protection the worst case scenario should be used, and this would normally be the 1Δn reading. No idea why they have removed the 5Δn column?
Andrew Betteridge:
There is only one line available to write comments on the existing installation, not enough for places I end up working in!
