Except it isnt. If you were born in 1929 or before it is free. (You may have done something towards the war effort!). My brother was 15 when the war ended; I cant say he did a lot but he gets a free passport.
I am a few years younger and I fought against EOKA is Cyprus. Is mine free? You know the answer!
There is a great case that any NS men who were on active service should get a free one and possibly all NS men; after all we existed on 28/- a week
For young pensioners that is £1.40 but blanco boot polish and other necessities were not quite free
