Download the factsheet: Do i need planning permission? 

Whether you need to submit a planning application for the works you want to carry out is dependent initially, on whether the works amount to ‘development’ and then secondly, whether the works are in a class of ‘permitted development’ which provide an automatic grant of planning permission so that a formal planning application is not required.

Development is defined under the 1990 Town and Country Planning Act as "the carrying out of building, engineering, mining or other operation in, on, over or under land, or the making of any material change in the use of any building or other land."

The starting point is to assume all buildings and engineering operations require a planning application to be submitted to the local planning authority.
