This comprehensive guide delves into every aspect of planning permission for temporary structures in the UK. We will clarify the legal definitions, outline the circumstances in which permission is required, and explore the exceptions. We’ll also discuss best practices for application, compliance, and post-installation obligations. Whether you are a construction professional, an event organiser, or a property owner considering temporary installations, this article will equip you with the knowledge you need to navigate the UK planning system confidently.
What is a Temporary Structure?
A temporary structure is broadly defined as any building or construction that is intended to remain in place for a limited period, rather than as a permanent fixture. Common examples include event marquees, pop-up shops, festival tents, site cabins, temporary classrooms, exhibition pavilions, portacabins, and even certain forms of scaffolding and canopies.
The duration for which a structure is classed as temporary can vary, but generally, structures intended to remain in place for less than 28 days are considered temporary under UK law. However, the definition is not always clear-cut. The nature of the structure’s use, location, and potential impact on the surrounding environment and community will influence how it is interpreted by local planning authorities.
Why is Planning Permission Important for Temporary Structures?
Planning permission is a legal requirement designed to ensure that new construction, whether temporary or permanent, does not adversely affect local communities, the environment, or compliance with national and local policies. Failing to secure temporary structure planning permission UK when needed can result in enforcement action, fines, or orders to dismantle the structure.
Even if a structure is temporary, its presence can impact factors like traffic, local amenities, visual landscape, noise levels, and the character of a neighbourhood. The planning system gives local councils the ability to assess these impacts before granting permission, ensuring that everyone’s interests are balanced.
Do All Temporary Structures Need Planning Permission?
Not all temporary structures require planning permission, but many do—especially if they are used for an extended period or in sensitive locations. The rules are set out under the Town and Country Planning (General Permitted Development) Order 2015 and various amendments.
In simple terms, you typically do not need planning permission if:
- The structure is in place for less than 28 days in any calendar year.
- The structure is for an agricultural, industrial, or certain other exempted uses.
- The structure meets criteria for “permitted development” under the relevant legislation.
However, these exemptions are subject to strict conditions around the size, location, and intended use of the structure. For all other cases, or where the project is more complex or high profile, seeking advice from your local planning authority is essential.
Common Types of Temporary Structures and Their Planning Rules
Event Marquees and Tents
Event structures are very popular across the UK for weddings, festivals, exhibitions, and corporate functions. For private land, marquees set up for less than 28 days per year often do not require planning permission. However, in public spaces, protected sites, or when the sale of alcohol or licensable activities are involved, you may also need a Temporary Event Notice (TEN) and to comply with other regulations.
Construction Site Cabins and Welfare Units
Cabins and units used for staff accommodation, site offices, or material storage are widespread on development sites. Usually, permitted development rights apply, particularly if the cabins will be removed after project completion. If the site is within a conservation area, close to listed buildings, or in an Area of Outstanding Natural Beauty (AONB), stricter rules often apply.
Temporary Classrooms and School Buildings
Due to rising pupil numbers and emergencies, schools sometimes need to install temporary classrooms. These structures often require planning permission, especially if planned for longer than 28 days or affecting pedestrian/vehicle access. It is advisable to liaise with the local education authority as well as planning officers early in the process.
Portable Retail and Hospitality Units
Pop-up restaurants, bars, and shops have become popular, especially in urban areas and at major events. Local councils will consider the intended time frame, potential impacts on public spaces, and whether the proposed use aligns with existing planning policies. In many cases, an application is needed before installation.
Temporary Storage Buildings
Warehouses, shelters, and covered storage for materials or equipment may fall under permitted development for industrial or agricultural purposes but often require permission on commercial or development sites. The period in use, size, and potential visual or access impacts are key considerations.
Planning Permission: When is it Required?
Generally, you should apply for temporary structure planning permission UK if:
- The structure will be in place for more than 28 days in a year.
- The structure is of such size, use, or location that it might pose risks to safety, amenity, local character, or protected environments.
- It is within or affects a conservation area, listed building, or heritage asset.
- The use involves members of the public or significant numbers of visitors/attendees.
- Licensable activities (such as alcohol sale) will be conducted from the structure.
- The structure could interfere with neighbours, highways, or public rights of way.
The above is not an exhaustive list; always check the details with your specific local planning authority as local plans sometimes introduce more stringent or permissive rules.
Exceptions and Special Circumstances
There are some exceptions to the broad rules on temporary structure planning permission UK, as governed by “permitted development rights.” These include agricultural developments, telecommunications equipment, and emergency response structures. The key qualifying factors are usually that the structure is directly related to the core use of the land and is genuinely temporary.
Examples of permitted exceptions:
- An agricultural storage tent on farmland, used only for the land’s agricultural business.
- Temporary site welfare units during an active building project, provided they are removed after completion.
- Emergency shelters erected in response to local disasters, like floods or fires.
Urban environments, conservation areas, and sites with protected status typically have much stricter requirements.
How to Apply for Planning Permission for Temporary Structures
If your structure is likely to require permission, it is recommended to submit a full planning application to your local council. The application process for a temporary structure is very similar to that for a permanent one, but you should be clear in your materials that the structure is for temporary use only.
Key documents usually required:
- Site plan indicating exact location and dimensions of the structure
- Design and access statements explaining its intended use and users
- Details of construction, materials, and safety provisions
- Justification for temporary need (e.g., during building works, events, seasonal trading)
- Proposed duration of installation and timeline for removal
You must submit the application via the Planning Portal or directly with the local authority. Fees are calculated based on the type and size of the structure and the complexity of the application.
How Long Does Permission Take and Last?
Most local planning authorities aim to determine planning applications within eight weeks, but for complex or contentious projects, it can take longer. You should factor this into your project timelines and avoid starting work before permission is granted.
When granted, the permission will state how long the structure can remain in place and under what conditions. For example, you may have permission for a marquee to operate each summer for a specified number of days or a pop-up unit for 12 months subject to annual review.
Temporary Event Notices (TEN) and Other Licences
While primarily associated with licensable activities like music, entertainment, and alcohol sales, Temporary Event Notices may also impact your use of a temporary structure. Even if a structure does not require full planning permission, you may need a TEN if it will be used for a public event involving licensable activities.
TENs are usually obtained through your local council and require advance notice (at least 10 clear working days). You can apply for several events in a year, within limits
