HSE Biocides ebulletin

Issued: 26 January 2024

This ebulletin contains information on regulating biocides in Great Britain (GB). 

The GB Biocidal Products Regulation (GB BPR) operates independently from the EU Biocidal Products Regulation (EU BPR), which applies in Northern Ireland.

Separate ebulletins containing information specific to regulating biocides in Northern Ireland are issued as appropriate.

Any person, company or taskforce/consortium can support an active substance/product type combination for renewal – it doesn’t have to be the original supporter.

Check the GB Article 95 List to see who the original supporters were.

If any of these active substance/product type combinations are important to you, consider contacting your supplier to let them know.

If a renewal application is not submitted for the above active substance/product type combinations under GB BPR, the approvals will expire. This means the active substances can no longer be used in biocidal products of the relevant product types in GB.
