Planning a home renovation in London can be an exciting endeavour, but navigating the planning permission process can often seem daunting. Whether you’re considering a small extension, a loft conversion, or a complete overhaul of your property, understanding the intricacies of planning permission is crucial to ensure your project’s success. This comprehensive guide provides London property owners with a step-by-step breakdown of the process, offering valuable insights and advice to help you confidently navigate the complexities and bring your dream home to life.
Do You Need Planning Permission?

Before diving into applications and consultations, it’s essential to determine whether your renovation project actually requires planning permission. Many smaller home improvements fall under permitted development rights, meaning you can proceed without formal permission. Common examples include:
  • Internal renovations: Redecorating, installing new bathrooms or kitchens, and most internal alterations generally don’t require planning permission.
  • Minor extensions: Small extensions, such as single-storey rear extensions within specific size limits, may fall under permitted development.
  • Loft conversions: In many cases, loft conversions are also permitted development, provided they adhere to certain conditions regarding roof height and volume increase.
However, it’s crucial to remember that permitted development rights can be complex and vary depending on factors like:
  • Location: Whether your property is located within a conservation area, Area of Outstanding Natural Beauty (AONB), or listed building.
  • Property type: Different rules apply to flats, terraced houses, detached properties, etc.
  • Size and scope of the project: Larger extensions, significant alterations to the roofline, or changes to the front of your property will likely require planning permission.
Always check with your local council’s planning department before starting any work to confirm whether your project requires planning permission. The Planning Portal website (www.planningportal.co.uk) also provides helpful guidance and interactive tools to help you assess your project.
Understanding Planning Permission Types

  • If your renovation project does require planning permission, it’s important to understand the different types of applications you might need:
  • Full Planning Permission: Required for major developments, such as large extensions, new buildings, or significant alterations to a property’s external appearance.
  • Householder Planning Permission: This is the most common type for homeowners, covering extensions, loft conversions, and alterations that affect the external appearance of your home.
  • Listed Building Consent: If your property is a listed building, you’ll need separate consent for any works that affect its special architectural or historic interest, in addition to regular planning permission.
  • Conservation Area Consent: Similar to listed building consent, this applies to properties within designated conservation areas and protects the area’s character and appearance.
