Planning Permission Guide Southwark

Thinking of extending or renovating your Southwark home? You’ll likely need planning permission – and understanding how it works locally can make a big difference to your timeline and success. In this quick guide, we break down the essentials you need to know about planning permission in Southwark.

Do I Need Planning Permission in Southwark?

That depends on your project. Many minor changes – like loft conversions or small rear extensions – may fall under permitted development rights, which don’t require full planning permission. However, if your home is in a conservation area, or if the work significantly alters the external appearance of the property, you’ll likely need to apply.

Common works that typically require permission include:

  • Large rear or side extensions

  • New builds or conversions

  • Flats or maisonette alterations

  • Projects in listed buildings or conservation areas

Southwark Council: What They Look For

Southwark Council assesses applications based on the Southwark Plan and London-wide policies. They’re focused on:

  • Protecting local character and conservation areas

  • Maintaining privacy and light for neighbours

  • Ensuring quality design and sustainable building practices

Every application is reviewed on its own merits, but poor drawings, vague plans, or missing documents can delay or derail the process.
