Once the approvals expire, the active substances will no longer be able to be used in biocidal products of the relevant product types in GB.
In addition articles treated with such products will no longer be able to be placed on the market in GB.
If you hold an affected GB BPR product authorisation or Control of Pesticides Regulations (COPR) product approval, we will contact you about cancelling or revoking your authorisation or approval. You will have an opportunity to submit comments or additional information and we will take account of these when finalising our decision.
If you are aware of any disproportionate negative impacts that are likely to arise from the expiry of the active substance/product type combinations listed, please contact us.
Stakeholders should note that biocides are in scope of the Sanitary and Phytosanitary (SPS) Agreement currently being negotiated between the UK and the EU. Once negotiations on the SPS Agreement have concluded, HSE will communicate further on any implications the Agreement has for the sector.
