Types of changes

Changes to a planning proposal can be agreed on before or after an application is decided.

Making changes before the application is decided is a useful way to improve developments and secure approval where permission might otherwise be refused.

Making changes after a proposal has been approved allows developers to respond to unexpected circumstances.

You can apply to make a change by applying for:

• a pre-decision amendment
• a non-material amendment
• a minor material amendment
• a variation of condition
• a modification of planning obligations
• a revised full application

We recommend the below guidance for making changes to planning applications.
