These regulations – made 24 November 2025 and coming into force on 30 December 2025 – amend how data‑protection periods apply under the GB version of the biocidal‑product rules (originally from EU Regulation 528/2012).
They update transitional provisions concerning access to active‑substance dossiers, replacing reference dates and adjusting which substance/product combinations receive prolonged protection.
The change affects producers of biocidal chemicals across Great Britain and helps reset how long their data remains protected under UK law.
