Regular Expression UK Post Code Validation Pattern

Hello,

Hope this will help you . /[A-Z]{1,2}[0-9][0-9A-Z]?s?[0-9][A-Z]{2}/gi;

Didn't work.  I read in another post that you had to put ^ at the beginning and $ at the end.

When I type e.g. SS0 0RY doesn't like it.  I tried without spaces and still complains.  Any ideas?
