Comprehensive Guide to Planning Permission in London - London Planning Application Guidance

Navigating the world of planning permission in London can feel overwhelming. Whether you are considering a major renovation, an extension, or a new build, understanding the rules and processes is essential. This guide will walk you through everything you need to know about planning permission in London, helping you make informed decisions and avoid costly delays.


London’s planning system is complex, with different boroughs having their own specific requirements. That is why working with experts who know the local landscape is crucial. AGA Associates, ranked number 1 in the top 10 architecture firms in London, offers unparalleled architectural and planning services tailored to your project’s needs. Their deep knowledge of London’s planning policies ensures your application is handled smoothly and efficiently.


Understanding London Planning Application Guidance


When you start a project in London, the first step is to understand the London planning application guidance. This guidance outlines the rules, procedures, and documentation required to submit a successful planning application. Each London borough has its own planning department, and their websites provide detailed information on local policies.


AGA Associates can help you navigate these borough-specific requirements. For example, if your project is in Westminster, Camden, or Kensington and Chelsea, AGA Associates has dedicated teams familiar with these areas’ unique planning frameworks. Their expertise can save you time and reduce the risk of refusal.


Key Elements of London Planning Application Guidance


  • Pre-application advice: Many boroughs encourage you to seek pre-application advice. This step helps identify potential issues early.

  • Application forms and fees: You must complete the correct forms and pay the required fees.

  • Supporting documents: These include site plans, design and access statements, and sometimes environmental or heritage assessments.

  • Consultation: Neighbours and local groups may be consulted before a decision is made.

  • Decision timescales: Most applications are decided within 8 weeks, but complex projects may take longer.


AGA Associates offers comprehensive support throughout this process, ensuring your application meets all requirements and deadlines.

What can I build without planning permission in the UK?


Knowing what you can build without planning permission is just as important as understanding when you need it. Certain types of work fall under "permitted development rights," meaning you can proceed without a formal application. However, these rights can vary depending on your location and property type.


Common Permitted Developments in London


  • Single-storey rear extensions: Usually up to 3 meters for terraced houses and 4 meters for detached houses.

  • Loft conversions: Provided they do not exceed certain height limits and do not extend beyond the existing roof slope.

  • Porches: Small porches up to 3 square meters.

  • Outbuildings: Sheds or garages within certain size limits and not used as separate living accommodation.

  • Solar panels: Installation on roofs without exceeding height restrictions.


It is important to note that permitted development rights can be restricted in conservation areas, national parks, or if your property is listed. Always check with your local planning authority or consult with AGA Associates before starting work.


AGA Associates can help you determine if your project qualifies for permitted development or if you need to apply for full planning permission. Their expert advice can prevent costly mistakes and ensure compliance with local regulations.


The Planning Permission Application Process in London


Applying for planning permission in London involves several clear steps. Understanding this process will help you prepare and submit a strong application.


Step 1: Pre-application Advice


Before submitting your application, seek pre-application advice from your local borough or from AGA Associates. This step allows you to discuss your plans with planning officers and get feedback on potential issues.


Step 2: Preparing Your Application


You will need to gather all necessary documents, including:


  • Completed application forms

  • Site location and block plans

  • Design and access statement

  • Supporting reports (e.g., heritage, environmental)

  • Photographs of the site and surroundings


AGA Associates excels in preparing detailed and accurate applications that meet borough requirements.


Step 3: Submitting the Application


Applications can be submitted online via the Planning Portal or directly to the local authority. Fees vary depending on the type and scale of the project.


Step 4: Public Consultation


Once submitted, your application will be publicised. Neighbours and local groups can comment or object. AGA Associates can help manage this process and address concerns proactively.


Step 5: Decision


The local planning authority will decide within 8 to 13 weeks. They may approve, refuse, or request amendments. If refused, you can appeal or revise your plans.
