The walk-round. Meet whoever ordered the report and agree what it covers. Here: a change of occupancy, a domestic property, wiring judged five-plus years old, no previous records.

Who sets itExample
ExtentAgreed with the clientAll fixed wiring — or one block of a school, if the rest was certified three years ago
LimitationsThe client places them on youA locked room; circuits that can’t be switched off
Operational limitationsYou find them on siteSuspected asbestos round a ceiling light: you don’t take it down, and you say so

All three go in the extent and limitations, with who they were agreed with. You’re not expected to be an asbestos expert, or to take a sample. If you suspect it, leave it and record why.

Supply characteristics come from looking: the marking on the supplier’s fuse (BS 1361 Type II, 100 A here), the earthing arrangement, the earthing and bonding conductor sizes. Read what’s marked. You don’t pull the supplier’s fuse to check.

Wiring age at a glance. Red and black means before the harmonised colours — they arrived in 2004 and became mandatory in 2006. It’s your judgement; it doesn’t have to be exact.
