What Are Commercial Building Classes Of Use?

In the UK, most commercial investment property will have its permissible use assigned to it by the local authority. Governing the type of business that can be conducted within a premises helps local government control an area’s development. There are usually ideas and plans for a town, village or city and controlling commercial activity will assist in the shaping of the area.

To restrict what is done or not done, classes of use for commercial property are applied and these cannot usually be changed without the agreement of town planners. Careful considerations will have been applied such as the available parking, noise levels, aromas, traffic problems, footfall and late-night activity. Pollution and environmental impact, issues surrounding health and safety, and historical buildings and existing businesses will also determine commercial use of properties. As the use of a property is pre-determined and not always very easy to change, anyone considering buying, selling renting or leasing a commercial property should understand the different classes and what they mean. The classes are broken down into A, B, C and D groups with subsections in each one.

Commercial Property Use Classes In The UK

Class – A1 is Shops

There are some commercial uses that do not fall under any of the above class uses. These are considered to be ‘Sui Generis’ which means ‘of its own kind’. There are a number of commercial premises that come under this classification, including theatres, hostels that do not provide any care services, scrap yards, petrol stations, nightclubs, launderettes, taxi businesses, casinos, amusement arcades, betting shops and payday loan shops. Some agricultural buildings will also come under this class. Change of use is permitted for these buildings via normal channels.

Some business activities will fall under more than one of the use classes for commercial property. It can be tricky to establish exactly which one fits the best. Other kinds of business may appear not to be covered at all. The above list is not exhaustive and there may be other factors to consider than those that are mentioned. It may be necessary to get legal advice to make absolutely sure of the correct classification of some businesses to ensure that errors are not made.

It may be possible to change the official classification of a commercial property, but it will be at the discretion of the local authority. Changes between some categories are much more simple than others, and in fact, some changes do not need permission as allowances have already been built into the classification.
