Planning pre-application advice charging scheme

To help sort out issues/problems and provide a more efficient planning process, we can offer you professional advice before you formally submit a planning application.

This is a discretionary service offered by the Council.  A Pre-Application Advice Charging Scheme was implemented on the 4th April 2011.  This now allows some of the costs of providing the service to be recovered from those who directly benefit.
