How long should a service cable remain in service? My grandparents still
have their orginal 1937 vintage cable and I wondered when they should be
replaced? They replaced the meter and part of the cutout last year.

Overhead or underground?
An underground cable of that vintage will probably be paper-insulated
(impreganted with a mineral oil), lead sheathed and armoured with steel
tape. It's life span is almost indefinite.
Overhead cables of that vintage *should* be considered highly suspect.
It will almost certainly be a poly-butyl jute construction, and the
insulation has a tendency to harden and crack, particularly at exposed
It is underground.
The house was last rewired with pvc in 1960. I am trying to convince them
to get it upgraded, as the earth connection is suspect T-N-S and no
crossbonds there are also some dark cables that have BICC Ashton cable
written on them. I suspect these may be VIR.

Here in Cheshire we still see some of the old lead sheathed cable in
the street lighting columns on the fifth core switch wire system.
The cable is thicker than split con and has flakes falling off it.
