When you plan to develop or renovate property in London, understanding the planning permission process is essential. London’s planning system can be complex, with different boroughs having their own rules and requirements. This guide will help you navigate the process confidently, ensuring your project runs smoothly from start to finish.
London’s property market is dynamic, and whether you are extending a home, converting a loft, or developing a commercial space, securing the right permissions is crucial. This guide will provide clear, practical advice to help you understand what you need to do, how to avoid common pitfalls, and why working with experts like AGA Associates can make all the difference.
London Planning Permission Guide: What You Need to Know
Planning permission is a legal requirement for many types of building work and changes of use. In London, each borough has its own planning authority, which means rules can vary depending on where your property is located. You must submit an application to the local council and wait for approval before starting work.
The process involves submitting detailed plans and documents that show what you intend to build or change. Councils assess these plans against local development policies, national regulations, and the impact on neighbours and the environment.
Key points to remember:
Always check with your local borough council before starting any work.
Some projects may be eligible for permitted development rights, which means you do not need full planning permission.
Applications can take up to 8 weeks or longer for complex projects.
Public consultation may be part of the process, especially for larger developments.
Appeals are possible if your application is refused, but this can add time and cost.

Understanding the Planning Permission Process in London
The planning permission process in London involves several clear steps. Knowing these steps will help you prepare and manage your project effectively.
Pre-application advice
Before submitting your application, seek advice from your local council or a planning consultant. This can save time by identifying potential issues early.
Prepare your application
You will need detailed drawings, site plans, and supporting documents such as design and access statements. Accuracy and clarity are vital.
Submit your application
Applications are usually submitted online through the Planning Portal or directly to the council. Fees vary depending on the type and scale of the project.
Consultation period
The council will consult neighbours and statutory consultees. This period allows for comments and objections.
Decision
The council will approve, refuse, or approve with conditions. You will receive a formal decision notice.
Post-decision
If approved, you must comply with any conditions. If refused, you can appeal or revise and resubmit your application.
AGA Associates supports clients through every stage of this process. Their expertise ensures applications are comprehensive and meet all requirements, reducing the risk of refusal.
What can I build without planning permission in the UK?
Certain types of work fall under permitted development rights, meaning you can build or alter without applying for full planning permission. However, these rights have limits and conditions, especially in London where conservation areas and listed buildings are common.
Examples of permitted development include:
Small single-storey rear extensions (up to 3-4 metres for detached houses)
Loft conversions within certain size limits
Some outbuildings like sheds or garages, provided they meet size and location rules
Changes of use between certain classes, such as office to residential (subject to conditions)
It is important to check if your property is in a designated area where permitted development rights are restricted or removed. Also, permitted development does not exempt you from building regulations, which must still be followed.
AGA Associates can help you understand what you can build without planning permission and advise when a full application is necessary. Their guidance helps you make informed decisions and avoid costly mistakes.
