I suggest that you do a search for existing scripts, either client side (such as javascript) or server side (such as PHP) to do what you want. I would think that many such scripts have been created, so some of them may be available for download.

UK post codes are in the format of SW1 ABC

The first set of characters can be 2, 3 or 4 digits though.
