Planning Permission Frequently Asked Questions
What is a ‘material change of use’?
This depends on the circumstances of each situation. Generally, any change of use of a substantial nature which has an impact or potential impact on neighbours or the local community will need planning permission. The planning authority can give advice on whether it considers any particular change of use is significant enough to be "material" for planning purposes. See Question 19 below for details of how to resolve a question whether a development is or is not exempted.
