I recently had to replace a ring main socket in a part of the house
that was re-wired 20+ years ago by an ex-electricity board inspector.

Such people re-wire their own homes in one of two ways:

1. With absolute perfection that they've learned from years of
experience; or

2. Cutting every corner that they've learned from years of experience.

Commiserations - I used to live in a Type 2 house too.
