Policy and guidance it draws on

GPDO 2015 Schedule 2 Part 1

Use these tools to determine whether you need planning permission and which type of application to submit. Getting the consent route wrong wastes time and money. Check PD rights first, then consider whether prior approval or full planning is the better option.
