1. What is planning permission?

Planning permission is the formal approval from your Local Planning Authority (LPA) required for certain types of building work or changes in land use.

2. Do I always need planning permission?

Not always. Some projects fall under "permitted development rights," which allow certain works without formal permission.

3. What counts as permitted development?

Permitted development includes minor extensions, loft conversions, and garden buildings, subject to strict limits and exclusions (e.g., conservation areas).

4. What types of planning permission exist?

• Full Planning Permission

• Outline Planning Permission

• Reserved Matters

• Prior Approval

5. Do I need permission for an extension?

It depends on the size and location. Small rear extensions may be permitted; larger or multi-storey ones typically require permission.

6. What about loft conversions?

Internal conversions may be permitted. Dormers or roof extensions often require permission, especially in conservation areas.

7. Do I need planning permission for a basement?

Usually not if it's within the existing footprint and incidental to the main house. Flats and external alterations typically require permission.

8. What about garden buildings, sheds, greenhouses?

Permitted for houses under certain conditions. Flats and listed buildings usually require permission.

9. Can I install solar panels without permission?

Often allowed under permitted development, subject to location and height restrictions.

10. Do I need permission for satellite dishes?

Generally allowed for houses. Flats, conservation areas, and listed buildings may require permission.

11. Will changing windows or doors need permission?

Houses usually don’t need permission unless in a conservation area. Flats and listed buildings do.

12. What if my property is listed or in a conservation area?

Most external works require planning permission. Additional restrictions apply.

13. How do I check if I need permission?

Consult your LPA or use the Planning Portal to assess your project.

14. What is a Lawful Development Certificate (LDC)?

A certificate confirming that a development is lawful and doesn’t require planning permission.

15. How do I apply for permission?

Submit an application via the Planning Portal with required documents and fees.

16. How long does it take for local councils to decide?

Typically:

• 8 weeks for householder applications

• 13 weeks for major developments

17. Can I amend my application after submission?

Minor amendments are usually accepted. Major changes may require a new application.

18. How are neighbours consulted?

LPAs notify neighbours and allow a 21-day period for comments.

19. What criteria do councils use to decide?

Applications are assessed against local and national planning policies, site history, and consultation feedback.

20. What if my application is refused?

You can appeal the decision or submit a revised application.

21. What’s the difference between planning permission and a building warrant (Scotland)?

Planning permission relates to land use and appearance; building warrants ensure construction safety and standards.

22. Is pre-application advice available?

Yes. Many councils offer pre-application services to help identify potential issues early.

23. Can large plots get outline permission only?

Yes. Outline permission assesses feasibility before detailed plans are submitted.

24. How can I speed up the decision-making?

Submit complete applications, use pre-application advice, and respond promptly to LPA queries.

25. What happens if I build without permission?

You may receive an enforcement notice requiring reversal of the work. Appeals are possible but ignoring notices can lead to legal action.
