how old is an electrical circuit

[sparkysdream]

I am about to be asked how old the wiring is in a victorian house.I know you had to use the new colours from about 2006. when did rcd come in. mcbo. new plastic consumer units about the same time as rcd. sockets were squarer 20 yrs ago. any other tips on dating wiring. this house appears to have had everything else updated but not the wiring.
