Due to the reduction of the avian influenza risk to poultry and captive birds, plans have been announced to lift the Avian Influenza Prevention Zone (AIPZ) housing measures in England from 15 May 2025.

The AIPZ mandating strict biosecurity measures will remain in place across Great Britain.

If you intend to allow your birds outside after 15 May 2025, you must take action now to prepare outside areas, please check the information available on GOV.UK.

As birds may have been housed for several months, there will be a 7 day transition period from 00:01 on 15 May 2025 until 00:01 on 22 May 2025 during which, where necessary, previously housed birds must be released gradually to minimise welfare issues. Keepers with any welfare concerns about their birds should speak to their vet. Further information is available in the press release on GOV.UK.

If you fall within a Protection Zone or Captive Bird (Monitoring) Controlled Zone, you are still required to house your birds. Please check the disease control zones on our avian influenza interactive map to see what restrictions are in place and the biosecurity guidance available on GOV.​UK.

We would like to thank all bird keepers for playing their part in managing this disease.

The Avian Influenza Prevention Zone (AIPZ) requiring mandatory biosecurity measures still remains in place across GB.
