The notes
Exactly as they are on the site.
Section 514 is identification and notices, and the exam likes it because the answers are lists.
Labels you'd expect on a consumer unit: RCD test notice, protective device identification, surge protection notice where an SPD is fitted, AFDD notice where fitted, and the circuit chart. In domestic premises the SPD notice and a fixed circuit chart aren't required where the information is in the certificate and its Guidance for Recipients (GN3 pp.46–47).
The circuit chart, and doing it properly
A protective device shall be arranged and identified so the circuit it protects can be easily recognised. That's the circuit chart the customer is left with — which circuits exist, what they feed and which device protects each.
