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 any of the active substance/product type combinations listed above, please contact us. Active substance expiry dates postponed in GB until 31 January 2027 As previously updated, the active substance expiry dates for all biocidal active substance/product type combinations which expire between 1 January 2024 31 December 2026, are able to be postponed until 31 January 2027.
