Your validation rules are incorrect. My post code (RH9 8AX) does not
conform to the above, neither does the BBC Broadcasting House in
London (W1A 1AA).

Yes, this could be done using Perl. I believe the following to be
an accurate summary of the UK post code validation rules, so should
help to get you started:
1. The total length must be 5, 6 or 7 characters, excluding the space.
2. A single space must be included in the post code.
2. The inward code, the part to the right of the space, must always
be 3 characters.
3. The first character of the inward code must be numeric.
4. The second and third characters of the inward code must be alpha.
5. The outward code, the part to the left of the space, can be 2, 3
or 4 characters.
6. The first character of the outward code must be alpha.
