Whether you require a polygon removing due to an error or if it is simply no longer required you will need to contact our Systems Support team.
We will require the request in an e-mail to ensure tractability and your e-mail should contain the below information.
Name of the polygon to be deleted
Reason for deletion (drawn in error, duplication, alerts no longer required on the area)
Once your request has been processed our team will reply to you e-mail confirming this.
