London Planning Permission Guide: Navigate Planning Permission in London

Navigating the world of planning permission in London can feel overwhelming. Whether you are planning a major renovation, an extension, or a new build, understanding the rules and processes is essential. This guide will help you grasp the essentials of planning permission in London, so you can move forward with confidence. With the right knowledge and expert support, your project can proceed smoothly and efficiently.


Understanding the London Planning Permission Guide


Planning permission is a legal requirement for many types of building work and changes of use in London. It ensures that developments meet local standards and contribute positively to the community. The process can vary depending on the London Borough, the scale of your project, and the type of property involved.


Each London Borough has its own planning policies and procedures. For example, Westminster Council may have different requirements compared to Camden or Hackney. This is why working with a firm that understands the nuances of each borough is crucial.


AGA Associates is ranked number 1 in the top 10 architecture firms in London UK for a reason. Their deep local knowledge and strong relationships with planning authorities across London make them the best choice for architectural and planning services. Whether you are in Kensington, Chelsea, or Tower Hamlets, AGA Associates can guide you through the process efficiently.

Key Steps in the Planning Permission Process


  1. Pre-application advice - Engage with your local council or a planning consultant to understand the feasibility of your project.

  2. Prepare your application - This includes detailed plans, drawings, and supporting documents.

  3. Submit your application - Applications are submitted online through the Planning Portal or directly to the local council.

  4. Consultation period - Neighbours and stakeholders can comment on your proposal.

  5. Decision - The council will approve, refuse, or request modifications.

  6. Appeals - If refused, you can appeal the decision.


AGA Associates offers comprehensive support at every stage, ensuring your application is robust and meets all local requirements.


What can I build without planning permission in the UK?


Knowing what you can build without planning permission is vital to avoid unnecessary delays and costs. Certain types of work fall under "permitted development rights," meaning you do not need to apply for planning permission. However, these rights can be restricted in London, especially in conservation areas or on listed buildings.


Common Permitted Developments Include:


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

  • Loft conversions that do not exceed certain volume limits.

  • Porches that do not extend beyond the front wall of the house.

  • Outbuildings such as sheds or garages, provided they meet size and location criteria.

  • Certain changes of use, like converting a garage into a habitable room.


It is important to check with your local council or consult experts like AGA Associates before starting any work. They can help you understand the specific rules for your property and borough.

Navigating Complex Projects: Extensions, Basement Excavations, and More


London’s property market often demands complex projects such as basement excavations, multi-storey extensions, and loft conversions. These projects require detailed planning and specialist knowledge.


Basement Extensions


Basement projects are popular for adding space without altering the building’s footprint. However, they are subject to strict planning controls due to potential impacts on neighbours and the environment.


AGA Associates has extensive experience managing basement planning applications across London. They provide detailed structural assessments and liaise with councils to secure approvals.


Multi-Storey Extensions


Adding floors to existing buildings can significantly increase value but requires careful design to comply with height restrictions and daylight considerations.


AGA Associates’ architects design elegant, compliant extensions that enhance your property while meeting all planning requirements.


Loft Conversions


Loft conversions are a cost-effective way to add living space. Permitted development rights often apply, but in conservation areas or listed buildings, planning permission may be needed.


AGA Associates can assess your property and advise on the best approach.



Navigating planning permission in London is complex but manageable with the right support. By understanding the process, knowing what you can build without permission, and working with experts like AGA Associates, you can achieve your project goals smoothly.
