Changing your planning application or approval

Changes to a planning proposal can be agreed 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 could 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

Unfortunately, there is currently no method prescribed by Government that allows developers to apply for an extension of the time to implement an existing planning permission. This means that developers will need to submit a new application if the prescribed period (normally three years) has passed.

The best way to avoid the need for changes is to ask for our pre-application advice​​
