UK Expert Committee on Pesticides (ECP): annual report 2025

Updated 17 September 2026

Chair’s foreword

Welcome to the 2025 annual report of the UK Expert Committee on Pesticides (ECP). The committee provides independent scientific advice to the UK government and the devolved governments (the Scottish Government, Welsh Government and the Northern Ireland Executive) on matters related to the approval of active substances and the authorisation and use of plant protection products (PPPs).

This year we have continued to see a trend where the cases we are asked to consider are increasingly multi-discipline and therefore need more detailed and wide-ranging understanding. Our work is confidential until completion of the application process, when our advice is published as part of the evaluation. Until that is complete it would be improper to make application-specific comment in our annual report. However, the committee have engaged with several such interesting active substance cases throughout the year. These require thorough understanding and often benefit from interaction between expert committee members and HSE regulatory specialists. I encourage those interested in further information to read our publicly available minutes and advice notes as they are published. These, along with other relevant information, are available on GOV.UK page UK Expert Committee on Pesticides (ECP).

I acknowledge, and thank the members for their full engagement throughout the year and the excellent support we receive from the secretariat. We are sure you will find this report an interesting and informative summary of the committee and its work.

As this report highlights, the membership evolves as terms end, or circumstances change. We would also be pleased to hear from interested candidates so your expertise can be considered when the need arises for new members. If you have any questions about this report or our activities, please contact our secretariat at ecp.crd@hse.gov.uk

Mr J Clarke, Chair, UK Expert Committee on Pesticides

Role of the committee

The ECP is an expert committee providing independent scientific advice to ministers in the UK and devolved governments on the authorisation of PPPs and on other matters related to the control of pests more broadly. Our terms of reference are set out in Annex 1.

A list of our members can be found at Annex 2. Our committee contains a broad range of expertise. Some of us are academics and others work in the industry. Our expertise includes specialist areas of study relevant to assessing the risks and benefits of pest, weed and disease control. Many of our members can broadly be categorised as experts in environmental sciences or in matters relating to human health and chemical exposure. Other members are appointed for their practical experience of pesticide use and regulation in the farming and amenity sectors. We also include members appointed to represent wider interests and consider issues from the public perspective. The expertise on the committee is regularly reviewed to ensure it continues to meet the advice needs of the government.

Members are appointed following an open public recruitment. All are appointed as independent individuals, not representing any particular interest or sector. In line with the Nolan Principles on public life we have declared any aspects of our work that may be perceived to present a potential conflict of interest. Members also work in accordance with the committee’s code of practice. We declare and describe any potential conflict of interest, both as a general annual declaration and in response to the specific agenda of each meeting.

We seek to operate objectively and transparently, publishing the agendas of our meetings and a detailed record of our discussions. We aim to place information in the public domain by default. However, this is constrained by the need to protect commercially sensitive information. Therefore, in some cases, we are unable to publish all material.

Our work in 2025

Day-to-day regulation of PPPs is carried out by the Health and Safety Executive (HSE) on behalf of the 4 governments. Anyone wishing to market PPPs must obtain an authorisation to do so. Authorisations are granted by HSE provided a robust evaluation of data demonstrates that use of the product will not harm human health or have unacceptable effects on the environment. Legal restrictions may be placed on the way products must be used (for example, the amount applied, timing of application, need for operators to wear protective clothing, avoiding applications close to environmental features) to ensure safety and environmental protection.

The vast majority of requests brought to the ECP for independent scientific advice relate to the approval of pesticide active substances and authorisation of pesticide products. The ECP will also be approached by government for advice or to provide information on emergency authorisations made under Article 53 of Regulation 1107 of 2009, novel or contentious issues where data or evidence could be interpreted in different ways or more than one approach to consider and on occasion biocide related issues.

The ECP met formally on 4 occasions and held numerous further interactions with specialist staff in HSE.

The committee’s input into the decision-making process continues to place a significant focus on using our expertise to understand the nature and degree of risk associated with proposed uses, the mitigation of those risks, the state of wider scientific literature and market conditions. This does not constrain us from developing a wider scientific view on these applications including from evidence beyond standardised regulatory testing.

This year we have advised on 2 applications for the approval, or changes to the conditions of approval, of active substances. These cases are often detailed and complex, requiring a significant amount of ECP time. In all such cases the ECP holds detailed meetings with HSE specialists on each area of science. HSE will seek specific advice on outstanding questions of science, but the ECP can explore any aspects of the risk assessment and underlying guidance they consider to be of importance. We expect most of our work in 2026 to be consideration of active substance applications.

Annual audit of HSE casework

In addition to our standard work, mentioned above, we undertake an annual exercise to quality assure the ‘routine’ HSE casework through a structured audit of finalised cases. A sub-group of ECP members were presented with a full list of HSE’s finalised cases and selected roughly 10% of these cases for a detailed review. The random selection also ensured that it included a number of cases where HSE rejected the application.

The sub-group were invited to choose cases from all completed PPP regulatory casework from the 2024 to 2025 financial year. This covered a broad range of regulatory applications including:

• applications for the approval of new products
• applications for the approval of new uses to existing products
• the extension of authorisation to include minor uses
• amendments to the terms of existing authorisations
• renewals of approvals for products and requests for experimental permits

Sub-group members were given full access to all the documentation HSE holds on these cases and were able to request further information or clarification from HSE as required.

The ECP sees a small proportion of HSE’s work on PPPs, generally the more novel and contentious cases, as such, we undertake this audit across a range of casework to help provide assurance that HSE considers all applications in a robust and appropriate manner. Our review of the work undertaken in the 2024 to 2025 financial year concluded that HSE has robust, detailed and appropriate procedures in place to consider applications.

Work with devolved governments

The ECP provides advice to the 4 governments of the UK based on the scientific evidence and data presented to it. We are asked to address specific questions of science and provide independent scientific advice that will support the effective and safe regulation of PPPs. For both new active substances and emergency authorisation applications, the ECP recognises that the 4 administrations also obtain advice from a range of sources that may also include economic and public policy perspectives in addition to that of the ECP.

To ensure we support the specific needs of the Northern Irish regulatory regime, the ECP has worked closely with the Department of Agriculture, Environment and Rural Affairs (DAERA) and the Northern Ireland Executive. As part of this work, DAERA provide regular briefings to the committee on the developments and issues relating to the Northern Ireland Protocol and the Windsor Framework.

Other aspects of our work included considering and/or advising on activities related to the following:

Technical updates

As part of the regulatory system the ECP has an interest in relevant work being carried out by, on behalf of or in collaboration with government. We are regularly updated on and discuss a range of projects and programmes. This year saw us engage with several technical and policy discussions carried out across government.

This included engaging with Defra on the UK Pesticides National Action Plan 2025, their pesticide load indicator (PLI) and new emergency authorisation guidance. Noting HSE’s work on their pesticide research and development programme, the work of the Expert Committee on pesticide residues in food and developments in the ongoing work on new technologies and drones. Through advisors from the Environment Agency, Natural England, the Food Standards Agency and the UK Health Security Agency, who attend our meeting, we engaged with a range of interesting and useful reports of their ongoing work.

Biopesticide Cloud

The cloud model has allowed us to bring in crucial expertise and specialist knowledge in specific areas which are not frequently seen in ECP’s work and has allowed us to adapt to the needs of a developing area of regulatory interest. This year saw the cloud members support on 2 specific regulatory applications being considered by HSE and provide advice to Defra on biopesticide research funding.

We will consider a similar approach for other areas of science and innovation where independent expert advice could help support the development of the regulatory regime. This is an important part of our work to support innovation and developments across the industry and regulation landscape.
