Property Developers’ Guide to UK Planning Use Classes

For property developers, understanding planning use classes is essential before buying a site, changing a building’s use or preparing a planning strategy. The use class of a property can determine whether a proposed change needs planning permission, may be possible under permitted development rights, or requires a full application.


In simple terms, a planning use class categorises how a building or piece of land is used. It gives owners, occupiers and local planning authorities a common framework for assessing whether one use can lawfully change to another.

What are planning use classes?


Planning use classes are categories established through the Town and Country Planning Use Classes Order 1987, which has been amended over time to reflect modern property use. They group certain types of activity together, such as housing, industrial premises, shops, offices and community facilities.


The key question for property developers is not simply what a building looks like. It is how it is lawfully used. A unit with a shopfront, for example, may have a lawful use that differs from its current appearance or temporary occupation.


Where the existing and proposed activities fall within the same use class, the change will often not amount to development and may not need planning permission. Where they fall into different classes, permission may be required unless a relevant permitted development right applies.

Why use classes matter to property developers


Use classes affect the viability, timing and risk of a project. Checking them early can prevent a developer from assuming that a building can be repurposed without consent.

  • Acquisition decisions: The lawful use may shape what a property is worth and what redevelopment options are realistic.
  • Planning risk: A move to a different class may require planning permission.
  • Programme and cost: Avoiding an unnecessary application can save time, expense and professional input.
  • Development strategy: Certain changes may be considered through permitted development rights rather than a full planning application.
  • Operational flexibility: Properties within broader use classes may allow different occupiers or business models without a fresh change-of-use application.


For this reason, property developers should establish both the current lawful use and the intended future use before committing to a project.

The main UK planning use classes


The following overview covers the principal classes relevant to many commercial, residential and community property projects.


Use Class B: industrial and storage uses

Use Class B covers types of industrial and storage activity, including general industrial uses and storage or distribution premises. Warehouses are a familiar example of a storage and distribution use.


For property developers assessing employment land, this distinction matters because an industrial building and a warehouse may have different planning characteristics and future conversion options.


Use Class C: residential and accommodation uses

Use Class C includes places where people live or stay. This broad category includes several different forms of accommodation, such as:

  • C1: Hotels and similar accommodation.
  • C3: Dwellinghouses, including houses and flats.
  • C4: Small houses in multiple occupation, commonly known as small HMOs.
  • Other Class C uses: Care homes, prisons and secure residential facilities.


Residential projects require particular care. A standard dwellinghouse, a small HMO, a large HMO and a hotel are not automatically interchangeable uses. Larger HMOs fall outside Class C4 and are treated as sui generis.


Use Class E: commercial, business and service uses

Use Class E was introduced in 2020 to simplify a wide range of high street and commercial uses. It includes many premises that were formerly split across older classes.


Examples commonly falling within Use Class E include:

  • Shops
  • Offices
  • Restaurants and cafés
  • Gyms
  • GP surgeries and other health-related premises
  • Nurseries


This broad class can offer useful flexibility for property developers. For example, a change from a shop to a restaurant may remain within Use Class E, meaning it would generally not require planning permission solely because of the use change.


That does not remove the need to consider other restrictions. Planning conditions, legal agreements, listed building controls and operational works may still create separate consent requirements.


Use Class F1: learning and non-residential institutions

Use Class F1 covers learning and non-residential institutional uses. Typical examples include:

  • Schools
  • Libraries
  • Museums
  • Places of worship
  • Public halls


These uses serve educational, cultural, religious and institutional purposes. A proposed move between F1 and a commercial or residential use should be assessed carefully, as it is likely to involve a change of use.


Use Class F2: local community uses

Use Class F2 is for local community uses. It includes facilities such as community halls, outdoor sports areas and swimming pools.


It also includes certain small local shops, particularly those under 280 square metres that serve an essential role in a locality, such as a village’s only shop. These are distinct from the wider commercial uses in Class E.


Sui generis: uses in a class of their own

Sui generis is a Latin term meaning “of its own kind”. A sui generis use does not sit within one of the standard use classes. It is treated separately because of its particular planning impacts or characteristics.


Examples include:

  • Pubs
  • Hot food takeaways
  • Nightclubs
  • Petrol filling stations
  • Theatres
  • Cinemas
  • Larger HMOs


Moving from a use within a standard class into a sui generis use will commonly require planning permission. For instance, changing a shop in Class E into a pub is not simply a change within the same commercial category.

How to assess whether a change of use needs planning permission


Property developers can use the following process as an initial planning check.

  1. Identify the existing lawful use. Do not rely only on marketing details, appearance or a previous tenant’s informal description.
  2. Identify the proposed activity. Be precise about how the building will operate, including whether it will be a shop, restaurant, office, HMO, pub or another use.
  3. Match both uses to the relevant planning classes. Establish whether they sit in the same class, different classes or whether one is sui generis.
  4. Check whether the change is development. A move within the same use class will often not require planning permission for the use change itself.
  5. Consider permitted development rights. Some changes between classes may be possible through a specific permitted development route.
  6. Check site-specific controls. Conditions, restrictions and other planning constraints can affect what is possible even where the classes appear favourable.

Example: changing a commercial unit to another business use


Suppose a vacant high street shop is proposed to become a restaurant. Both uses can fall within Use Class E. In that situation, the change of use may not require planning permission because it remains within the same class.


Now consider changing that same shop into a pub. Pubs are sui generis rather than Class E. The proposal is therefore a move from a standard use class to a standalone use, and planning permission is likely to be needed.


The important lesson for property developers is that two uses may both appear commercial while being treated very differently in planning terms.

Example: changing Class E premises to a dwelling


A commercial property in Use Class E may sometimes be converted to a dwellinghouse in Class C3 through a permitted development right known as Class MA. This route concerns the change from Class E commercial, business and service uses to residential use.


Permitted development rights can be valuable because they may avoid the need for a full planning application. However, they are not a substitute for proper checks. The relevant right, the current lawful use and any applicable restrictions should all be considered before relying on it.

Common planning use class mistakes


Assuming all commercial uses are interchangeable

Use Class E combines many commercial activities, but it does not include every high street use. Pubs, takeaways, cinemas and nightclubs are examples of uses that are sui generis.


Confusing a small HMO with a larger HMO

Small HMOs fall within Class C4, while larger HMOs are sui generis. This difference can be critical to the planning route and project risk.


Ignoring the lawful existing use

A building’s planning position depends on its lawful use, not merely on the use a buyer hopes to introduce. Establishing that starting point is an essential part of due diligence.


Treating permitted development as automatic

Permitted development rights can create opportunities, including Class MA conversion from Class E to C3 residential use. They should still be checked against the property’s specific circumstances before a project proceeds.


Focusing only on the use class

A favourable use class position does not necessarily authorise physical building works, alterations or other changes. Separate planning considerations may apply.

A due diligence checklist for property developers


Before acquiring or repurposing a property, use this short checklist:

  • Confirm the current lawful planning use.
  • Define the intended end use clearly.
  • Identify the relevant use class for both uses.
  • Determine whether the proposed use is sui generis.
  • Consider whether a same-class change avoids a planning application.
  • Review whether a permitted development right could apply.
  • Check for planning conditions or other site-specific restrictions.
  • Separate the change-of-use question from any proposed building works.

Key takeaway


Planning use classes are a practical tool for understanding whether a property can change from one activity to another. For property developers, the biggest opportunity is often identifying lawful flexibility before assuming that full planning permission is needed.


Start with the existing lawful use, compare it with the intended use, and then assess whether the proposal stays within the same class, moves into a different class or relies on permitted development rights. That early assessment can shape a more efficient and informed development strategy.

Frequently Asked Questions

What is a planning use class?

A planning use class is a category that describes how a building or land is used. It helps determine whether changing a property from one activity to another requires planning permission.

Do property developers need planning permission to change a building’s use?

Not always. If the current and proposed uses are within the same planning use class, the change may not require planning permission. A move between different classes, or into a sui generis use, is more likely to require consent unless a permitted development right applies.

What uses are included in Class E?

Class E includes many commercial, business and service uses, including shops, offices, restaurants, cafés, gyms, GP surgeries and nurseries.

Are pubs included in Use Class E?

No. Pubs are sui generis, meaning they are in a class of their own. A change from a Class E use, such as a shop, to a pub is therefore likely to require planning permission.

Can a Class E property be converted into a home?

A change from Class E to a Class C3 dwellinghouse may be possible using the Class MA permitted development right. Property developers should check whether the right applies to the individual site before proceeding.
