Changes to Annexes II and III of GB Biocidal Products Regulation

Changes in the data requirements for active substances and biocidal products will apply from October.

The Biocidal Products (Health and Safety) (Amendment and Transitional Provision etc.) Regulations 2024 came into force on 6 April 2024.

This legislation updates some of the data requirements in Annexes II and III of GB BPR to reflect developments in science and technology. These include the use of alternative testing approaches to determine some hazardous properties which previously relied on animal testing.

The new data requirements will apply to GB applications received from 6 October 2025. They will not be applied to pre-existing applications.
