Further information
We also have a more detailed document to explain our application validation requirements (pdf / 338 KB), along with a separate appendix to explain the requirements for biodiversity and geological assessments (pdf / 300 KB).
Every application needs a location plan and site plan showing the location and boundaries of the site you're planning to work on.
You can use the portal "Buy a Plan" service to make sure you meet our requirements, whether you're a planning professional or a first-time applicant.
If your planning application includes a proposal to connect to any non-main drainage system (such as a treatment plant or septic tank), then you will also need to complete and submit an additional foul drainage assessment form (pdf / 115 KB) before your application can be accepted. This will help us to identify:
- any concerns that might lead to pollution or nuisance arising from a non-mains drainage system
- a need for significant changes to a developer’s intended foul drainage arrangements
and should avoid an application for an environmental permit being refused or particularly stringent conditions imposed.
