Understanding Planning Permission Requirements in London
Planning permission requirements in London are designed to ensure that developments are sustainable, safe, and in keeping with the local environment. Before you start any construction or renovation, you must check if your project needs planning permission.
Key Factors Influencing Planning Permission
Location: Different London boroughs have specific rules. For example, Westminster has stricter controls on listed buildings, while Tower Hamlets focuses on affordable housing contributions.
Type of Development: Extensions, loft conversions, basement excavations, and new builds all have different requirements.
Heritage and Conservation Areas: If your property is listed or in a conservation area, additional permissions are needed.
Impact on Neighbours: Proposals must consider privacy, light, and noise impacts.

Prepare Documentation: This includes detailed plans, design and access statements, and environmental assessments if required.
Submit Application: Applications are submitted online via the Planning Portal or directly to the borough council.

What Can I Build Without Planning Permission in the UK?
Understanding what you can build without planning permission is crucial to avoid unnecessary delays or legal issues. The UK government allows certain developments under "permitted development rights," but these come with limits.
Common Permitted Developments
Single-storey rear extensions: Usually up to 3 metres for terraced houses and 4 metres for detached houses.
Loft conversions: Provided they do not exceed certain height limits and do not extend beyond the existing roof slope.
Porches: Up to 3 square metres in area.
Outbuildings: Such as sheds or garages, provided they are not used as separate living accommodation and meet size restrictions.
Solar panels: Installation on roofs within size and location limits.
Restrictions and Exceptions
Properties in conservation areas, national parks, or listed buildings often have reduced or no permitted development rights.
Basement excavations usually require full planning permission.
Multi-storey extensions or significant changes to the building’s footprint always need permission.
AGA Associates can help you determine if your project qualifies as permitted development or if you need to apply for full planning permission. Their expertise ensures you stay compliant with all regulations.
