A principle of the planning legislation (Use Classes Order) is that planning consent is not required to change use within a Use Class.
With effect from 1st September 2020 the Use Classes Order will be radically different, making it possible to change uses without planning consent when previously consent would have been required.
There will be no more 'A' (shop) use class. A1 (retail shop), A2 (professional services) and A3 (restaurant) will all move to new use class E, as will B1 (offices, R&D and light industrial), as will medical / health uses e.g. doctors surgery or yoga studio, as will day nurseries. This means an existing office could be turned into a restaurant or creche without requiring planning consent.
Pubs, wine bars (old class A4) and hot food takeaways (old class A5) will become sui generis meaning that planning consent would be required for a change of use.
There will be two more new use classes: F1 and F2.
Class F1 will include education, place of worship and public halls.
Class F2 is for 'local community' uses including shops selling essential goods where there is no other such facility within 1km and halls 'for the principal use of the local community'.
