processes. Class B2 - general industrial use General Industrial Use for the use of carrying on an industrial process other than one falling within class B1 and they may not be correct. Class B8 – storage or distribution Applies to properties which are used “for storage or as a distribution centre” Class C – hotels, hostels and dwelling houses Class C1 Class C1 deals with hotels, boarding houses and guest houses which do not offer care as part of their services.

Large houses in multiple occupation - with more than 6 people sharing are unclassified by the Use Classes Order. In planning terms they are described as being sui generis.
