That's right, 999, if you ain't going to eat it and it ain't vermin causing problems, don't shoot it.

The strict UK laws don't only apply to handguns. All guns, except air rifles and air handguns that have muzzle power below 12lbs/ft and 6lbs/ft respectively, have to be licenced and, when not in use, stored in locked steel cabinets which are securely fixed to a wall or similar. Same applies to live ammunition. The police inspect the cabinet and its location as part of the licence application procedure.

Gun licences, except those for shotguns, must state the specific land on which the gun is to be used and, if it's not their land, shooters must carry written permission from the landowner. Getting a bullet gun licence in the UK is not an easy process in the first place, as you can probably imagine.
