Planning permission in the UK can feel confusing — so here are ten of the most common questions people ask us in 2025, with plain-English answers.
1. Do I need planning permission or is it PD?
Many small householder works are allowed under the General Permitted Development Order (GPDO). Flats don’t benefit from PD, and councils can remove rights via an Article 4 Direction.
2. How long does a decision take?
Householder applications: around 8 weeks.
Minor developments: 8–13 weeks.
Major schemes: 13+ weeks.
A Pre-Application enquiry can improve your chances.
3. What drawings are needed?
Scaled plans, elevations, block plan, and a location plan. Supporting reports may also be required (heritage, flood, trees, design). Your Full PLAIN Report lists them exactly.
4. How much are the fees?
Set nationally. Householder applications are usually a few hundred pounds. Larger schemes cost more. Your PLAIN Report will confirm the exact fee.
5. What is Article 4?
An Article 4 Direction removes specific PD rights. Often applies in Conservation Areas.
6. Will neighbours be consulted?
Yes — on planning applications. For PD, usually not, except in some prior approval cases.
7. What is Prior Approval?
A lighter-touch check required for some PD classes (e.g. larger rear extensions).
8. How can I improve my chances?
Comply with policy, provide correct drawings, address constraints early.
9. Can I apply retrospectively?
Yes, but it carries risks. Councils may enforce. Seek advice first.
10. What if I’m refused?
You can resubmit (sometimes free), appeal, or adjust your design.
