Group,

I'm aware of the regulations that don't allow you to put light
switches high up where young children can't reach them, but require
them to be at a level where visiting wheelchair users can switch
lights on and off to their heart's content. I believe power points
have to be slightly higher than was typical in older properties.

What do the regulations say concerning an extension to an existing
(1950s) house? Can I (or a suitable part-P qualified electrician) put
the light switches and power points at whatever height I want in the
extension (e.g. at the same height as in the original house), or do
they have to be at the new regulated height?

Put the at whatever height you want.
