A set of self assessment forms have been developed for you to assess whether you require planning permission for your proposed development. These can be found under self assessment forms.
If you answer 'yes' to any of the questions in the forms, or do not comply with any conditions, then you will need to submit a planning application. This can be submitted online through the Planning Portal.
You are also advised, if not already known, to check whether permitted development rights have been removed, if your property is in a conservation area or if it is a listed building.
