Approval of active substances
In the first stage of the registration system, active substances are assessed for their impact on workers applying the product, consumers of treated produce, residents living adjacent to application sites and others who may be passing-by at the time of treatment; whether and how the pesticide might move throughout the environment once it has been applied; the impact on the environment, in particular water bodies and wildlife; and product efficacy.

Approved Active Substances:
Active substances that have been shown to be without unacceptable risk to people or the environment are added to the list of approved active substances, which can be found on the following databases:
- Approvals Register (for active substances approved in Great Britain)
- EU database (for active substances approved in the EU)
Renewal of approval of active substances
Active substances are initially approved for a fixed period (usually 10 years). If they are to remain approved after that period, they must be re-assessed to ensure that they continue to be without unacceptable risk to people or the environment according to the latest standards of assessment.
Renewal of active substances is organised in phased programmes depending on the expiry date of the approval. Further information about the renewal process can be found on the EU website and the GB overview:
- GB guidance - information about the renewal of approval of active substances
- EU website - information about the renewal of approval of active substances
If active substances are not renewed, any plant protection products containing those active substances must be withdrawn from the market.
If active substances are renewed, the approval period is extended and existing authorisations of plant protection products containing those active substances must also be renewed by the Member States and Great Britain where they are already authorised.
