I'm often wondering or being asked how old the wiring is, particularly when it's been disguised with new sockets. There are plenty of clues, but I wasn't in the trade when the changes came about. Here are a few to start. Feel free to add dates for other significant changes.
When did main bonding increase from 6 sq mm to 10 sq mm?
When did earths on lighting circuits become obligatory?
When did the earth conductor in 2.5 sq mm T&E increase from 1 sq mm to 1.5 sq mm?
When did stranded T&E for socket circuits disappear and what xsection is it?
When did twisted flex for pendants go?
When did voltage operated earth leakage trips get the boot?
Cheers
