UK postcode reg ex with space

Question

I need a javascript reg ex that forces the user to enter a space in their UK post code.

Can somebody please help? Those I have found seem to allow for optional spaces which is not what I'm after.

Answer 1

Something like this? Believe it catches all UK postcodes, at least it caught all the ones I can think of off the top of my head

/^(\w{1,2}\d{1,2}\w?\s\d\w{1,2})$/
