Avian influenza prevention zone (AIPZ) housing measures gradually being lifted
Mandatory housing measures for poultry and other captive birds have started to be gradually lifted across England from 00:01 on Thursday 15 May 2025.
As birds may have been housed for several months, there is a 7 day transition period from 15 May 2025 until the housing measures are fully lifted on 22 May 2025.
During this time, where necessary, poultry keepers should release previously housed birds gradually to minimise welfare issues.
You should follow guidance on preparing to let your birds outside again. This includes cleansing and disinfecting hard surfaces, fencing off ponds or standing water and reintroducing wild bird deterrents.
Birds must still be housed if you are in a protection zone or captive bird (monitoring) controlled zone. All keepers must continue to follow strict biosecurity measures to prevent bird flu and stop it spreading.
The lifting of AIPZ housing measures is in response to a reduction in bird flu risk levels and is supported by the latest scientific evidence.
The AIPZ mandating strict biosecurity remains in place in England, Scotland and Wales. Bird gatherings also remain banned.
