How long does planning permission last in the UK?

Planning permission is essential to starting any construction or renovation & remodelling project in the UK. It permits the legal rights to start any development or alteration on a property. Well, planning permissions are not indefinite, still, understanding its exact duration is crucial to avoid unnecessary complications or project complexities.

In this detailed guide, we will assist you in exploring the lifespan of planning permission and the related key aspects by providing insights that will be both practical as well as easy to understand. So, let’s dig a little deeper to understand what planning permission is and how long does planning permission last?

What is Planning Permission?

To keep it straight, planning permission is a formal approval that you will require from the local planning authority “LPA” to proceed with certain building works or changes to land use. It ensures that proposed developments will align with the local policies and building regulations and do not negatively impact the surrounding areas or the neighbourhoods. 

So, if you are planning to do an extension, a new build, or a significant modification, securing planning permission is often a prerequisite. In the United Kingdom, planning permission acts as a safeguard to maintain order and aesthetic harmony within communities. It is a legal framework that balances private development needs with public interests, such as environmental protection, infrastructure capacity, and historical preservation. 

Duration of Planning    

Normally, planning permission is valid for three years once it is granted.  This means you must start the development within this timeframe to keep your permission valid. The definition of “starting” can vary but generally includes any significant work such as digging foundations, installing drainage, or demolishing structures.

For outline planning permission, which approves the development in principle, you must submit reserved matters (detailed plans) for approval within three years. Once the reserved matters are approved, you usually have an additional two years to begin the work. 

These timelines ensure that developments are carried out promptly and in line with current planning policies. Failing to commence work within the stipulated timeframe results in the planning permission lapsing. This necessitates reapplication if the project is to proceed. It’s also worth noting that pre-commencement conditions attached to the planning approval must be fulfilled before starting work; otherwise, the project may face enforcement action.

Understanding these durations and requirements can save significant time, effort, and resources, particularly for projects involving multiple phases or extensive preparatory work.

What Happens After the Expiry of Planning Permission?

In case your planning permission expires before starting any of the project, then you will lose all the legal rights to carry out the development. This can come with the various challenges that will include the need to resubmit applications and potentially adapt to new local planning policies or regulations. These changes might affect the design, scope or even the feasibility of your original proposal. 

Expired planning permission can also pose financial and logistical hurdles. For example, reapplication costs, delays in project timelines, and potential increases in material or labour expenses can escalate the overall budget. Moreover, public sentiment or community objections might have shifted, introducing new hurdles to obtaining approval.

To avoid such complications, developers are advised to closely monitor the expiration date of their planning permission and ensure that preparatory work begins within the permitted timeframe. Early consultation with professionals can help identify potential bottlenecks and create a clear action plan for timely project execution.

Can You Renew the Planning Permission?

Well, in the previous years it was possible to apply for an extension of planning permission through a renewal process. Although since 2009, this option has been broken off for most of the standard permissions. So, if your planning permission expires, you will now be required to submit a new application to proceed with the development. 

For outline planning permissions, you may still benefit from extensions if you have not yet submitted reserved matters for approval. It is critical to understand the specific rules and timelines applicable to your project, as these determine whether an extension or reapplication is necessary. Consulting with a planning expert or solicitor can provide clarity and ensure compliance with current regulations.

When reapplying, consider that updated local policies, environmental assessments, or community feedback may affect the outcome. Engaging a professional service to handle the process can increase your chances of success.

What Type of Planning Permission Do You Have?

The type of planning permission you hold significantly influences the steps required to maintain or reapply for it. Common types include:

  1. Full Planning Permission: This is a comprehensive approval for a detailed proposal. After approval, the work must start within three years. 
  2. Outline Planning Permission: This grants approval in principle and requires reserved matters (detailed designs) to be submitted within three years. Following approval of reserved matters, work must start within an additional two years.
  3. Householder Planning Permission: Specific to smaller residential projects such as extensions, loft conversions, or garden structures. Like full planning permission, it typically has a three-year validity.
  4. Retrospective Planning Permission: Occasionally required if work has been carried out without prior approval. This type of permission does not have a standard expiration period but should be approached carefully to avoid enforcement action.

Each type of permission carries unique conditions and timelines. Identifying your permission type is essential to understanding the requirements and avoiding unnecessary complications during the development process.

What Are the Laws for Starting Work for Planning Permission?

To activate your planning permission, you must demonstrate that work has “commenced” within the allotted timeframe. The law requires that this work be significant and carried out by the approved plans and conditions.

Key aspects include:

  • Substantial Start: Activities such as digging foundations, laying drainage systems, or demolishing existing structures are typically considered valid commencement of work. However, cosmetic or preparatory tasks, like site clearing, may not qualify.
  • Compliance with Conditions: Many planning permissions come with pre-commencement conditions, such as environmental surveys, archaeological assessments, or discharge of specific planning conditions. These must be fulfilled before any work can legally begin.
  • Inspection by Authorities: The local planning authority (LPA) may require evidence that the work complies with the approved plans and conditions. This could include photographic records, site inspections, or formal notifications of commencement.

Failing to comply with these laws can lead to enforcement actions, fines, or even project termination. Developers are advised to liaise with the LPA and seek professional advice to ensure all requirements are met before starting work.
