Update: 31/03/2023 


Our permitting charges will remain at 2022-2023 rates until any new charging schemes are agreed.  


See details of the proposed charges we intend to implement for 2023-2024, subject to Ministerial approval. 

Before you apply

If you would like to make any changes to your permit you need to apply for a variation. For further advice on how you can vary a permit please see application forms and guidance notes available from the links below. All applicants (except those applying for an administrative change only) must fill in part A and F, and complete the appropriate part C sections.

Type of changes you can make

Administrative changes to your permit or updating your details. You must fill in Part C0.5 unless you are changing an address or contact details when you should also fill in Part A with the new details. To check what an administrative variation is, please see the guidance for Part C0.5 or refer to the examples listed in our fees and charges scheme.

If you have more than one environmental permit at the same location, you can apply to consolidate your permit. If you would like to consolidate your permit, then please contact our customer contact centre on 0300 065 3000 to discuss your application.

If you have a bespoke permit and want to vary to add or become a standard rule activity, you should go to our apply for a standard rule waste activity permit page and follow the information there.
