Add correct spacing to postcode (UK)

I've got the following to add spaces to a postcode:

function isValidPostcode(p) { 
var postcodeRegEx = /[A-Z]{1,2}[0-9]{1,2} ?[0-9][A-Z]{2}/i; 
return postcodeRegEx.test(p); }

function formatPostcode(p) { 
if (isValidPostcode(p)) { 
    var postcodeRegEx = /(^[A-Z]{1,2}[0-9]{1,2})([0-9][A-Z]{2}$)/i; 
    return p.replace(postcodeRegEx,"$1 $2"); 
} else {
    return p;
}}

It checks the postcode and adds a space. It works for postcodes with SA143TG and adds a space to make SA14 3TQ, but with SA13TQ it doesn't work.

Any ideas?

Instead of this line

var postcodeRegEx = /(^[A-Z]{1,2}[0-9]{1,2})([0-9][A-Z]{2}$)/i;

try this

var postcodeRegEx = /([A-Z]{1,2}[0-9]{1,2})([0-9][A-Z]{2})/i;
