GB Biocidal Products Regulations (BPR) and How Water Treatment Products Complies


Following the end of the Transition Period, Great Britain is no longer part of the EU scheme for regulating biocides.

The EU biocides regulations have been copied into GB law and Biocidal products are controlled under the following effective 1st January 2021:

  • Great Britain (England, Scotland and Wales) under the GB Biocidal Products Regulation (GB BPR)
  • Northern Ireland under the EU Biocidal Products Regulation (EU BPR)

As GB BPR is a stand-alone regime, the HSE have provided guidance for the following items:

A Great Britain version of the EU list of active substance suppliers (the ‘Article 95’ list) has been established. The list mirrors the EU list (at the point the transition period ended) and will operate in the same way.

A biocidal product authorisation that is valid in Great Britain, will remain valid from 1 January 2021 until its normal expiry date. However, the authorisation holder will need to be established in the UK (including Northern Ireland) by 1 January 2022.

Active substances that were already in the EU Review Programme on 31 December 2020 are intended to be included in the GB Review Programme. For the active substance to be evaluated under the GB Review Programme, a full application to HSE is to be submitted by the substance supplier within prescribed timescales.

Biocidal products are defined as those active substances and preparations containing one or more active substances intended to destroy, deter, render harmless, prevent the action or otherwise exert a controlling effect on any harmful organism by chemical or biological means.

The GB BPR covers 22 different product types under 4 main groups which includes disinfectants, preservatives, pest control and antifouling products. For example Liquid Cooling and processing systems are included in Product Type 11.
