United Kingdom: no general licence, but the landholder’s consent
Entering land without the owner’s or occupier’s consent to hunt deer there is an offence.
British law does not organise hunting around a national licence the way continental systems do. What governs access is the consent of whoever holds the land. The Deer Act 1991 says so in its first section: a person is guilty of an offence if they enter land without the consent of the owner or occupier, or other lawful authority, in search or pursuit of any deer with the intention of taking, killing or injuring it. It is also an offence, while on any land, to take, kill or injure a deer intentionally — or attempt to — to search for or pursue a deer with that intention, or to remove a deer's carcase, without that consent or other lawful authority. The act allows a good-faith exception: there is no offence where the person acted in the belief that they would have had the owner's or occupier's consent had they known of the act and its circumstances, or that they had other lawful authority. An authorised person who reasonably suspects such an offence may require the person to give their full name and address and to quit the land forthwith. Hunting law is devolved in the United Kingdom: these acts apply to England and Wales, and in part to Scotland; Scotland and Northern Ireland have their own deer legislation.
