Whether you need planning permission for a dropped kerb or not depends on the classification of your road. To find out the classification of your road please check the Essex Highways website.
If your road is listed as unclassified, a private road or a private street then planning permission is not required for a dropped kerb. If your road is listed as A, B or Class III then planning permission is required for a dropped kerb.
If planning permission is required for a dropped kerb, then an application must be submitted using the householder application form. Further information regarding submitting a planning application.
Essex County Council Highways must always be contacted as Highways consent is required for a dropped kerb even when planning permission is not required.
