Compulsory housing orders have been introduced across all of England, Wales and Northern Ireland in a bid to combat the ‘significantly elevated threat’ of Highly Pathogenic Avian Influenza (HPAI, Bird Flu).
It was only a couple of weeks ago that a mandatory housing order was announced in a number of specified counties in England that were considered to be at high risk (see here) but this has now been extended to all counties in England, Wales and Northern Ireland as the number of outbreaks has increased.

The compulsory housing order in England came in to force on 6 November 2025 (see press release from Defra here), on 6 November 2025 in Northern Ireland (see press release from DAERA here), and will begin across Wales from 13 November 2025 (see press release from Welsh Government here).
In the last two weeks, outbreaks of Highly Pathogenic Avian Influenza have been declared as follows:

SCOTLAND
There are currently no confirmed outbreaks in Scotland
Many of the reported incidents have resulted in the declaration of a 3km protection zone and a 10km surveillance zone around the infected premises, with flocks culled and strict biosecurity measures in place.
The former Director of Science at the Government’s Animal & Plant Health Agency (APHA), Professor Ian Brown, has warned that the current H5N1 virus is “as super-infectious as any high pathogenicity avian influenza we’ve ever seen” and has warned farmers to “prepare for the worst” (see here).
Amidst all this, conservationists have argued that the release of ~60 million non-native gamebirds for shooting created more risk for the spread of this highly contagious disease, especially when research revealed that a large number of shooting estates were not even declaring they had birds, making it impossible for Defra and APHA (Animal & Plant Health Agency) to monitor and manage the risk.
Defra and Natural England responded by withdrawing General Licence 45 (the licence permitting the release of gamebirds on or within 500m of a Special Protected Area (SPA)) and heavily reducing the number of individual licences for the same purpose (see here). In August, enhanced mandatory biosecurity measures were also introduced, including for game bird shoots, and these remain in place, although not all game shoots are complying….more on this shortly.
