The uk regulations on explosives have been amended
http://www.hse.gov.uk/explosives/
The above link will take you to the site ,surprisingly (or not) this does not seem to have been publicised much if at all.
The only other control has been the requirement to show FAC to obtain primers ,& as yet no others that I am aware of .
I did see a suggestion that the uk may introduce firearms licensing in the banding system that is used in NI/ ROI - just thought I would add that as a point of interest.
