Navigating the planning application process in London can seem complex, but understanding its key stages is crucial for residents, developers, and anyone interested in the city's urban development. This wiki page breaks down the typical journey of a planning application from initial submission to final decision.

What is a Planning Application?

A planning application is a formal request to a local planning authority (LPA), such as a London borough council, for permission to carry out building work or to change the use of land or buildings. Most new building, rebuilding, and significant alterations require planning permission.

The Stages of a Planning Application

The process generally follows these steps:

Pre-Application Advice

While not always mandatory, seeking pre-application advice from the local planning authority is highly recommended, especially for larger or more complex developments. This stage allows you to discuss your proposals, understand local policies, and identify potential issues early on. It can save time and money later in the process.

Application Submission

The application is submitted to the relevant borough council. This typically involves completing specific forms, providing detailed plans, drawings, and supporting documents (such as design and access statements, heritage statements, or environmental impact assessments, depending on the project's nature). Applications can usually be submitted online through the Planning Portal or directly to the council.

Validation

Once received, the LPA will check if the application is complete and valid. If anything is missing or incorrect, they will contact the applicant to request the necessary information. An application is only formally registered and processed once it is deemed valid.

  • Planning Application Form: Official request for permission.
  • Site Location Plan: Shows the application site in its wider context.
  • Elevations and Floor Plans: Detailed drawings of the proposed building's exterior and interior.
  • Design and Access Statement: Explains the design principles and how access is addressed.
  • Supporting Reports (e.g., AoN): Assess impact on heritage assets, environment, flood risk, etc.

Consultation

After validation, the LPA will undertake a consultation period. This involves notifying neighbours, local community groups, statutory consultees (like Historic England or the Environment Agency), and advertising the application. The aim is to gather comments and objections from interested parties.

Site Visit and Assessment

Planning officers will usually visit the site to assess the proposal in its physical context. They will evaluate the application against relevant national and local planning policies, including the London Plan and the borough's Local Plan.

Officer's Report and Recommendation

The planning officer will prepare a report detailing the proposal, the planning policy framework, the consultation responses, and their assessment. This report concludes with a recommendation to either approve or refuse the application.

Decision Making

For most applications, the decision is made by a senior planning officer under delegated powers. However, more significant or controversial applications are decided by the borough's Planning Committee, which is made up of elected councillors. The committee hears from planning officers, applicants or their agents, and sometimes objectors before making a decision.

Decision Notice

The applicant will receive a formal decision notice stating whether planning permission has been granted or refused. If granted, the notice will often include conditions that must be met before or during development (e.g., materials to be used, hours of construction).

Post-Decision

If permission is granted subject to conditions, the applicant must discharge these conditions before commencing work. If permission is refused, the applicant has the right to appeal to the Planning Inspectorate.

Key Considerations and Policies

When assessing a planning application, London boroughs and the Greater London Authority (GLA) consider a range of factors, including:

  • National Planning Policy Framework (NPPF): Sets out the government's planning policies for England.
  • The London Plan: The strategic spatial plan for London, setting out objectives and policies for development across the city.
  • Borough Local Plans: Detailed development plans for each London borough, which include specific policies and site allocations.
  • Design Quality: Proposals are assessed on their architectural merit, contribution to the street scene, and overall design quality.
  • Impact on Neighbours: Considerations include overlooking, loss of light, noise, and impact on amenity.
  • Sustainability: Policies related to energy efficiency, flood risk, and climate change mitigation.
  • Transport and Infrastructure: The impact on local transport networks and the availability of infrastructure.

Understanding the London planning application process empowers individuals to engage more effectively with the development shaping their city. For detailed information, always refer to the specific London borough's planning department website and the Planning Portal.
