Generally, if it is proposed to change from one Use Class to another, you will need planning permission. Most external building work associated with a change of use is also likely to require planning permission. There are some exceptions that are covered in more detail below.
If you are proposing to change the use of buildings or land, we would always recommend that you seek advice from the local planning authority to confirm whether or not planning permission or prior approval is required.
Additionally, before you lease or buy a property for your business, you should check whether you need to obtain planning permission or prior approval for its intended use and, if so, your chances of getting it.
Changes of use not requiring planning permission
Changes within the same Use Class
Generally, planning permission is not needed when the existing and the proposed uses fall within the same Use Class. This includes Use Classes E, F1, and F2 that were introduced in September 2020, enabling a wider range of use changes within each of these classes.
For example, a greengrocer’s shop could be changed to a shoe shop without the need for planning permission.
However, if building work is associated with the proposed change of use, planning permission may be required for that work.
Permitted development
Some changes from one Use Class to another are covered by 'permitted development' rights (meaning that planning permission is deemed to have been given). Some building work associated with these changes of use can also be covered by 'permitted development' rights.
However, to be eligible for any of these rights, the proposals must meet the specific limitations and conditions set by national legislation. These conditions may also require you to make a prior approval applciation.
For example, a unit of up to 500 square metres floorspace in ‘General Industrial’ use (Use Class B2) could be changed to a ‘Storage and Distribution’ use (Use Class B8) under 'permitted development' rights.
Please note in regard to changes to Use Classes from 1 September 2020: For any reference to permitted development rights, and for restrictions to them or applications for prior approval, the Use Classes in effect prior to 1 September 2020 will be the ones used until the end of July 2021 (this is defined as the ‘material period’ in legislation so may be referred to as such). Despite this, you may now be able to change use within one of the ‘new’ Use Classes that was introduced, as detailed above.
If your proposal meets the permitted development requirements but you still want proof that the development is lawful, you can apply for a lawful development certificate (LDC) for the proposed use. Find out more about Lawful Development Certificates.

Restrictions on permitted development
The table above summarises the permanent changes of use covered by ‘permitted development’ but there are additional limitations and conditions that any such proposals will need to comply with to be eligible.
These will vary depending on the current/existing and proposed use of the land or building, and its location. Where proposals are not eligible, a planning application will usually be required.
The most common is where the land or buildings are designated or protected. For example, if the land may be in a Conservation Area or the proposals may affect a Listed Building. Each change of use covered by ‘permitted development’ will have a specific list of designations/protections where the rights do not apply. There may also be additional consents required such as Listed Building consent.
There are also often limits on the size of the proposed change of use (which may also need to account for any previous changes of use of the same type), these are summarised in the table above. Where the change of use creates houses, there may be limits on the size and type.
The change of use may also only be eligible for ‘permitted development’ based on the dates and time periods that the current/existing use took place.
If agricultural tenancies are (or have been) in place, then there are specific restrictions to ensure the tenants’ rights.
Removal of permitted development rights
Local authorities can remove permitted development rights in certain areas, meaning that you will require planning permission. Proposals should always be checked with the local authority before starting work.
Find out more about removal of permitted development rights.
Prior approval
Some changes of use are subject to ‘Prior Approval’. This will require that an application is made to allow the local authority to assess the impacts and risks of the proposal.
You can apply for all 'change of use' types of prior approval online through the Planning Portal.
The impacts and risks to be assessed will vary depending on the current/existing and proposed use of the land or building, and its location. For example, these could include the design or external appearance, transport and highways impacts, or flooding risks.
All prior approval applications require a fee to be paid to the local planning authority, though there are exemptions for some specific circumstances.
