All sorted. I went to W.H.Smiths and a nice guy filled out a form which i then took home - with K.T - to complete. I packaged up the K.T. with form, and give it to the Post Office.
The Mail address is to W.H.Smiths in the UK - why they did not explain that when i enquired i cannot understand. This would have gained some peace of mind, but there you go.
Regards
