The Planning Permission Process Explained
Securing planning permission involves several key steps. Understanding these will help you prepare and avoid common pitfalls.
Pre-application Advice
Before submitting your application, seek pre-application advice. This step allows you to discuss your plans with planning officers or consultants like AGA Associates. They can identify potential issues early and suggest modifications to improve your chances of approval.
Submitting the Application
Your application must include detailed plans, drawings, and supporting documents. AGA Associates assists in preparing these materials to meet the specific requirements of your local council.
Consultation Period
Once submitted, the application undergoes a consultation period. Neighbours, local groups, and statutory consultees can provide feedback. Your planning consultant will help manage any concerns raised.
Decision
The local planning authority will approve, approve with conditions, or refuse your application. The decision usually takes 8-13 weeks, depending on the project size and complexity.
Appeals and Amendments
If refused, you can appeal or amend your application. AGA Associates offers expert advice on how to respond effectively to refusals or conditions.
By following these steps and working with experienced consultants, you can streamline the process and increase your chances of success.

On what grounds can planning permission be refused?
Understanding why planning permission might be refused helps you avoid common mistakes. Local authorities consider several factors when assessing applications:
Non-compliance with Local Plans
If your project conflicts with the local development plan or neighbourhood plan, it is likely to be refused. For example, building heights or densities that exceed limits can cause rejection.
Impact on Neighbours
Planning authorities assess whether your development will cause unacceptable harm to neighbours’ privacy, light, or outlook. Overbearing extensions or overlooking windows are common concerns.
Design and Appearance
Poor design that does not respect the character of the area or listed buildings can lead to refusal. AGA Associates specialises in sensitive designs that enhance local heritage and meet planning standards.
Environmental and Traffic Issues
Projects that increase traffic congestion, cause noise pollution, or harm protected habitats may be refused.
Insufficient Information
Applications lacking necessary details or technical reports often face delays or refusals.
AGA Associates’ expertise in preparing thorough, well-justified applications helps you avoid these pitfalls. Their knowledge of London boroughs’ specific requirements ensures your project meets all criteria.
