How to Get Planning Permission in a Conservation Area: A Step-by-Step Guide

If you live in a conservation area, you’ll already know it’s both a blessing and a challenge. You enjoy historic charm and character – but strict planning controls can make even small changes feel complicated.

The truth is, many planning applications fail because homeowners or developers don’t understand the additional requirements councils expect. This can lead to costly delays, redesigns, or outright refusals.

In this guide, our team at Aurora Heritage Planning – specialists in conservation and heritage planning – share a simple step-by-step process to help you secure planning permission in a conservation area. You’ll learn how to avoid common pitfalls, prepare stronger applications, and get expert support along the way.

Why Conservation Areas Matter

Conservation areas are designated to protect places of special architectural or historic interest. Councils are particularly cautious about changes that could alter their character – from large extensions to seemingly small alterations like new windows or external finishes.

Under the National Planning Policy Framework (NPPF), local authorities must consider the impact of proposals on the “significance of heritage assets”, which includes conservation areas. The goal isn’t to freeze areas in time, but to manage change sensitively.

👉 Tip: This is where heritage planning consultants like Aurora can help. We ensure your project is designed and documented in a way that meets council expectations from the start.

Step 1: Do You Need Planning Permission in a Conservation Area?

Not all work requires permission, but rules are much stricter in conservation areas. Common projects that may require consent include:

  • Replacing windows, doors, or roofing materials
  • Demolishing walls, outbuildings, or boundaries
  • Building an extension (even small ones)
  • New external finishes such as render, cladding or paint
  • Works to trees (many councils require six weeks’ notice)

👉 Tip: Don’t assume your project is exempt. “Permitted development” rights are often restricted in conservation areas. Check with your local council or ask Aurora for advice before starting.

Step 2: Research the Character of the Conservation Area

A strong application shows you understand the setting. Before drawing up plans:

  • Review your council’s Conservation Area Appraisal (if available).
  • Walk around your street: note materials, proportions, rooflines, trees, and views that define the space.

This context forms the foundation for your application and proves your design respects the area.

Step 3: Prepare a Heritage Statement (or Heritage Impact Assessment)

Most applications in conservation areas require a Heritage Statement.

  • What it is: A report that explains the significance of the conservation area and assesses how your proposal affects it.
  • Why it matters: Councils rely on it to decide if your works preserve or enhance the area’s character. Without it, your application may be invalid.
  • What to include:
    • Description of your property and its context
    • Significance of the conservation area
    • Details of your proposed works
    • Assessment of impact on local character

👉 Tip: Supporting visuals (maps, photos, annotated plans) make your case stronger. Aurora’s team prepares professional heritage statements that give your project the best chance of approval.

Step 4: Use Sympathetic Designs and Materials

Design choices are closely scrutinised in conservation areas. To boost your chances:

  • Use traditional or matching materials such as slate, brick, or timber.
  • Respect existing proportions, rooflines, and features like chimneys or boundary walls.
  • Don’t dismiss contemporary design – high-quality modern proposals can succeed if they’re sympathetic to the setting.

Step 5: Submit a Strong Application

When you’re ready to apply (via the Planning Portal or your local council), make sure you include:

  • Application forms
  • Scaled plans and drawings
  • Heritage Statement / Heritage Impact Assessment
  • Design and Access Statement (if required)
  • Supporting surveys or reports (tree, flood risk etc., if needed)

👉 Tip: A clear, professional submission reduces back-and-forth with planning officers – and Aurora can prepare the full package for

Step 6: Be Ready for Consultation

Once submitted, your application will go through a consultation process. Local groups, councillors, and neighbours may comment.

  • Expect objections – they’re common.
  • Be ready to show how your design respects the area.
  • Engage positively – councils prefer cooperative applicants.
