The neighbour notification system aims to strike a balance between ensuring public engagement whilst at the same time ensuring efficient processing. Any requirement for planning authorities to undertake a property search, for example, would introduce new obligations and add cost and delay.
Neighbour notification is only one way in which the public can find information about planning applications. All planning authorities are required to publish online a list of all planning applications in their area (a weekly list of applications must also be sent to every community council in the area). Certain types of application may also require notices to be published in newspapers.
