AIPZ housing measures in England from 6 November 2025 and Wales from 13 November 2025
Great Britain (England, Scotland and Wales) is in an avian influenza prevention zone (AIPZ). By law you must follow strict biosecurity and hygiene rules to prevent bird flu and stop it spreading.
- In England and Wales there are mandatory housing measures which mean you may have to house your birds.
- If you have more than 50 birds you must house them. This applies to all types of birds.
- If you keep less than 50 birds and they are for your own use only (for example you do not sell or give away their eggs or meat), you do not have to house them.
- If you keep less than 50 birds but you do sell or give away their eggs, poultry products or live birds, you must house them. These birds are known as ‘poultry’.
