Permitted Development vs. Full Planning Permission: What London & Surrey Homeowners Need to Know

Navigate complex regulations effortlessly with this guide, tailored for successful home improvements in Greater London

Key Takeaways

• Permitted Development (PD) allows certain extensions/alterations without full planning permission, reducing time and costs

• Borough variations significantly impact PD rights, requiring careful research before starting projects

• Full planning involves detailed applications, neighbor consultations, and potential revisions—budget 8-13 weeks

• Low-competition keywords: Surrey extensions PD rights, Worcester Park planning permission, London permitted development loft conversion

Understanding Permitted Development Rights

Permitted Development (PD) grants homeowners the right to undertake specific building projects without needing full planning permission. These projects include:

• Single-story rear extensions: Max 4m depth (terraced/semi-detached) or 8m (detached) in England

• Loft conversions: Subject to volume limits and roof height restrictions

• Internal alterations: Non-structural changes like kitchen/bathroom renovations

However, PD rights are not universal and often restricted by:

• Conservation areas: Stricter limits on exterior changes

• Listed buildings: Consent required for all alterations

• Article 4 Directions: Local restrictions removing PD rights

Always confirm PD eligibility with your local council’s planning portal before starting any work.

London & Surrey Borough-Specific Regulations

Common Variations

Worcester Park Spotlight

For homeowners in Worcester Park, understanding the subtle differences between Merton and Sutton’s planning policies is essential. While both boroughs generally follow national guidelines, local interpretations can vary significantly.

Navigating Borough Portals

• Merton: Use the Merton Council Planning Portal to check specific property restrictions6

• Sutton: Consult the Sutton Council Planning Guidance for conservation area maps and Article 4 Directions

When Full Planning Permission is Required

Full planning permission becomes necessary when your project:

• Exceeds PD limits: Larger extensions, significant roof alterations

• Alters listed buildings: Any changes to protected structures

• Occurs in sensitive areas: Conservation zones, Areas of Outstanding Natural Beauty

3. Application Submission: Submit plans, supporting documents, and fees via the borough’s online portal (fees vary)

4. Neighbor Consultation: The council will notify neighbors who may be affected by your project
