"25 years old" and "7/0.029" are not compatible attributes. Metric cable
came into use around 1970, so either the house is older than you think or
you've got stranded 2.5mm^2.

It's all that damp green electricity that is being generated by the offshore
wind farms . Expect a lot more of it and a big increase in prices :-)

Thanks guys - I'll relay both on.

Neville has decided to replace stained sockets, clean goo off wire ends,
and keep fingers crossed.
No sign of embrittlement yet, and as he says as long as he doesn't
disturb the wiring it doesn't matter if it does go brittle.
