Question to the Home Office:

To ask the Secretary of State for the Home Department, how many legal cannabis farms there are in the UK.

There are currently 102 licences in extant to cultivate low THC cannabis (Industrial Hemp) in Great Britain. The majority of these licences will be issued to farms. A small proportion of these licences will be issued to educational or research institutes.

The licences are generally issued for a validity period of three growing seasons and therefore will include licences issued in 2023, 2024 and 2025.

Standard ‘cannabis cultivation licences’ may be issued for research or pharmaceutical purposes.

In the last year (to 11 November 2025) 16 companies have been issued ‘High THC’ cannabis cultivation licences at a total of 19 sites. A proportion of these licences will have been issued for research purposes.
