Guidance on the types of pesticide applications that can be made before you apply for authorisation of a pesticide product:
Carry out research and development: trials permit
To carry out research and development work on an approved or unapproved active substance or plant protection product you must apply for a trials permit. Includes renewal of trials permits.
Trials permit application and renewal[1]
HSE consideration of a study protocol
If you would like HSE to comment on a draft study protocol to confirm that the design and methodology is appropriate and will potentially address a specific data gap, you can apply to HSE.
More on HSE consideration of draft study protocols[2]
Official recognition to conduct efficacy trials
If you wish to carry out efficacy testing and analysis on a pesticide product for yourself or on behalf of a third party, your testing facilities must be 'officially recognised'.
Apply for official recognition[3]
Active substance source change: technical equivalence
In order to include a new active substance source in a pesticide product to be marketed in the UK, you will need to submit separate technical equivalence applications for Great Britain and Northern Ireland.

Meeting with HSE before you apply: pre-submission meeting
You can have a pre-submission meeting with HSE before you apply for active product authorisation or active substance approval.
We can answer your questions, consider any issues and establish a timetable for submission.
You can arrange a pre-submission meeting using form CRD10 (.docx) [5].
Find out more about pre-submission meetings[6].
Active substance applications
You must apply for the approval of an active substance before it can be used in a pesticide product.
More about active substance approval and how to apply.[7]
Emergency authorisation
If you wish to use a non-authorised product because of a danger that cannot be contained by any other reasonable means, you may be able to apply for an emergency authorisation.
