Bat survey reports    

If you're development is in an area highlighted as a bat habitat on the planning constraint checker map then you'll need to do a bat survey report, also known as a preliminary roost assessment. 

This applies to all applications, including householder applications, which propose any of the following: 

• Demolition
• Modification to a roof including extensions and alterations which would affect a roof
• Work to a bridge, cellar, air raid shelter or tunnel

The bat survey report must be done by a qualified ecologist and submitted with the application. It might mean the planning application is refused if you don't.

Community Infrastructure Levy Form

Every application needs to include a Community Infrastructure Levy Form (PDF document) even where you consider the development isn't liable for the levy. Complete and submit this form via the Planning Portal with your application. 

Heritage Statements

If your development affects a heritage asset you will need to submit a Heritage Statement. This should show how the development does not negatively impact any heritage asset. For more information, visit our listed buildings, heritage and conservation areas page.

Volume calculations for 'countryside' applications

For new extensions or replacement residential buildings located within countryside or green belt you need to provide volume calculations. These need to be measured externally. 

These should identify the size of the dwelling at the time it was built or at 1948 if it was built before. Volumes for any subsequent extensions should be calculated together with the volume of the proposed extensions.

Minerals Resource Assessment

If your site is within a mineral safeguarding area, as set out on our planning constraints map, you may need to complete a Minerals Resource Assessment. This will typically apply to large scale developments but should show the impact of the proposal on the potential for extraction of minerals.
