Use Class A2 (financial and professional services) comprises premises that have a display window at ground level, but excluding betting offices or pay day loan shops. It relates to financial services such as banks and building societies, professional services (other than health and medical services) and includes estate and employment agencies.
Use Class A2 premises can benefit from a variety of different permitted development opportunities to change use without requiring a full planning application. There are a number of conditions and limitations to such a change however and further detailed information about this can be found here on the Planning Portal website. This website also details other restrictions to permitted development that may be in place, such as planning conditions or Article 4 Directions, and it is recommended you get confirmation from the local planning authority about changes of use proposed using permitted development rights.
If an A2 premises does not benefit from permitted development rights, planning permission may be sought to change it to another use. You can learn more about this process here.
