Planning permission guidance
What is planning permission & when you need it.
Planning permission is generally required for most forms of 'development' including new buildings, extensions, material changes of use, or significant alterations. You may not need it for minor internal works or small external alterations that fall under 'permitted development rights'. These rights can be restricted in conservation areas, national parks, areas of outstanding natural beaty, or for listed buildings. Always check with you Local Planning Authority (LPA).
