HSE Biocides ebulletin

Issued: 14 April 2023

 

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.

You will have an opportunity to submit comments or additional information and we will take account of these when finalising our decision.
