What is an enforcement warning notice?

An enforcement warning notice (EWN) formalises the process whereby a local planning authority (LPA) can invite a retrospective planning application for development that has taken place without permission.

The EWN explains:

  • What the LPA believes the breach is.
  • What action is expected.
  • The deadline for submitting a retrospective application.

If the application is not submitted by the date specified, the LPA may proceed with formal enforcement action. There is no right of appeal against an EWN.
