The wiring and house are about 25 years old, dry and in vg
condition, standard 7/029 T&E.

"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.

Or his house was fitted out with Old Stock Cable!!

I wondered that myself, but now find I had got construction date wrong -
was circa 1965, consistent with Andy's 1970 metrication.

My own house was built in the Copper Crisis of 1968, with uncoated
aluminium cable. Now almost completely replaced. Only one fire.
Where was the IEE in 1968?
