I received a number of old Licencing documents via email from a shy contributor (many thanks, I won't tell) and I have added some more up to date documents of my own. If you have any further information or licences that you wish to see included then, by all means, send them in (they don't have to be in PDF format, I can convert most image files).
All the documents on this page are in PDF format. If you require Adobe Reader then that can be downloaded (free) from

By 1946 there was a proper Amateur Wireless Station Licence. It is interesting to notice that, at this time, licensees were all limited to a maximum of 10 Watts DC input power, modulation type was AM or FM only and that the 70cm band was from 420 - 460 MHz.

By 2002 the Amateur Radio Licence was issued by Ofcom. 2002 saw the start of the Foundation Licence, followed by the Intermediate Licence and the "new" Full Licence from 2004. 
This is a Foundation Licence dating from the mid 2000s. The class was printed along with the holders' details at the time of issue (the personal details have been blocked out).
These licences were issued with a booklet of Terms and Conditions known as the BR68. There were 3 versions, one for each class;

Notes are made throught the book as to which class (Foundation, Intermediate or Full) is allowed to do what.
Here is a Full Licence cover page, the personal details have been blanked out.
