Do I Need Planning Permission?
Under the Town and Country Planning Acts, planning permission is required for development. Development is defined as building, mining, engineering or others operations or a material change of use. (Please note: Engineering includes excavation and changing land levels)
Secondary legislation allows certain development to proceed without applying for planning permission. This is often called 'permitted development'.
Permitted Developments Rights are sometimes removed from properties when planning permission is granted. This means that a planning application will need to be submitted. Contact Planning Admin to check to see if permitted development rights have been removed.
You may also need permission if your house has been previously extended or was built in the last few years. Extensions to flats and maisonettes will always require permission, including those converted from houses. Some permitted development rights require you to notify the Council before you start work. Further guidance can be obtained via the Planning Portal's interactive house .
The legislation on residential extensions and other minor works changed in 2015. The attached checklist PDF, 181.45 KB will help you work out if planning permission is required.
The Planning Portal has information and guidance for householders and commercial properties. They have helpful mini guides for common householder projects and can help you if you want to calculate the volume of your roof extension only - volume calculation
