Authorities and activities

Finding the right authority

The table below will help you find out which of the authorities you should report a plant protection products incident or concern to in Great Britain (England, Scotland and Wales, this does not include Northern Ireland).

If your plant protection product concern relates to a company based in, or an incident that has occurred in, Northern Ireland please visit the Department for Agriculture, Environment and Rural Affairs (DAERA) website.

If the incident / concern involves…

…it should be reported to…

people – where someone has used a plant protection product at your home as part of their work, a professional gardener for example


people – where someone has used a plant protection product at your home not as part of their work, such as yourself or another member of the general public

your local authority

people – other than the scenarios described above, such as in agriculture or forestry use

either HSE or your local authority depending on the type of place involved –

If you're still not sure which authority you should report to, don't worry! All of the authorities work together, so we will make sure your report gets to the right place.

Other ways the authorities work together include:

Enforcement laws

The responsibilities of the different authorities described in the table above come from general health and safety law working in combination with more specific enforcement laws for GB PPPR.

General health and safety law

GB PPPR specific law

These laws also define a number of offences and the powers that the authorities may use. Find out more about offences and powers.

Schemes and activities

HSE also runs a number of schemes and activities focussed on the effects of the use of plant protection products in particular areas.

Wildlife Incident Investigation Scheme (WIIS)

The Wildlife Incident Investigation Scheme (WIIS) investigates the death and illness of wildlife, livestock, pets (usually cats and dogs) and beneficial insects (usually honey bees, bumble bees and earthworms) that are suspected to be caused by poisoning from pesticides (or biocides).

WIIS is primarily a monitoring tool that provides additional information to HSE, which may prompt the reassessment of authorised products to prevent further incidents. However, enforcement action may also be taken where there is clear evidence of a breach of the law.

Find out more about WIIS.

Human health enquiry and incident survey (HHEIS) and resistance reporting

Action for authorisation holders

GB PPPR requires product authorisation holders to report new information about products and active substances that may affect their authorisation. You should report to HSE without delay if you become aware of:

You should include as much information as possible in your reports, including:

The information reported to HSE may prompt the reassessment of authorised products to prevent further incidents. However, enforcement action may also be taken where there is clear evidence of a breach of the law.

To ensure that HSE is receiving this information, we conduct an annual survey where authorisation holders are required to tell us about any information they have received concerning the adverse effects on people only.

Please note: this does not mean you should wait for us to write to you! If you have received information concerning adverse effects, you must tell us without delay.

The results of the survey are compiled into an anonymous report – approval / authorisation holders and products will not be identified. For the latest report, or reports from previous years, please contact us.

Pesticides residues monitoring

HSE regulates pesticide residues on behalf of the Department for the Environment, Food and Rural Affairs (DEFRA) and other UK government departments. As part of this work HSE runs an annual programme of surveys of food available in GB to check that pesticide residue levels do not exceed the legal levels. 

The UK government is advised on the programme by a panel of independent experts – the Expert Committee on Pesticide Residues in Food (PRiF).

Official controls

To maintain standards of food and feed safety, there are official controls on the production, processing, distribution and use of plant protection products. To implement these controls effectively, HSE has a specific inspection and enforcement scheme which focusses on regular inspection and sampling without prior notice at all stages of production, processing, distribution and use.
