Making a Planning Application
How to apply for planning permission for building work or change of use.
Overview
Most building work and changes of use require planning permission from your local planning authority (LPA). Some minor works fall within 'permitted development' and do not need planning permission. This guide covers the standard householder and full planning application process.
Who Can Use This Process
- You are likely eligible to use this guide if your situation involves a planning application.
- You have a genuine legal basis for the matter (contract, tort, statutory right, etc.).
- You have made reasonable attempts to resolve the matter directly with the other party first.
Step-by-Step Process
Check if You Need Planning Permission
Not all work requires planning permission. Permitted development rights allow certain minor works (small extensions, loft conversions, fences under 2m) without a formal application. Check the Planning Portal or contact your LPA for advice.
- Listed buildings, conservation areas, and flats have more restrictive rules
- Consider applying for a Lawful Development Certificate if in doubt
Pre-Application Advice
Most LPAs offer a pre-application advice service (sometimes free, sometimes for a fee). This gives you early feedback on whether your proposal is likely to be acceptable and any changes that might improve your chances.
Prepare and Submit Your Application
Submit your application through the Planning Portal (planningportal.co.uk) with the required documents: application form, site plan, floor plans, design and access statement (if required), and the fee.
- Householder applications require accurate plans — consider using a planning consultant or architect
Consultation and Determination
The LPA will consult neighbours, parish councils, and statutory consultees (highways, environment agency, etc.). They must determine most applications within 8 weeks (householder) or 13 weeks (major applications).
Decision
The LPA will grant permission (possibly with conditions), refuse permission (with reasons), or ask for amendments. If refused, you can appeal to the Planning Inspectorate within 6 months (12 weeks for householder appeals).
Costs
Important Warnings
Carrying out development without planning permission is a breach of planning control — the LPA can issue enforcement notices.
Planning permission usually expires after 3 years if not commenced.
Building Regulations approval is separate from planning permission — you may need both.

- The end-to-end timeline depends on which stage you're at. Common steps run on these timeframes: "Response within 2–4 weeks"; "Submitted online"; "8–13 weeks". Add court / counterparty response time on top — disputed matters can run months longer than the bare minimum.
- How much does it cost?
- Main outlays are: Householder application — £258; Full application (per dwelling) — £578; Appeal — Free. Court fees often qualify for Help with Fees remission if you're on a low income. Solicitor fees are extra and vary widely — many matters can be done as a litigant in person.
- What are the most common mistakes to avoid?
- Watch out for: Carrying out development without planning permission is a breach of planning control — the LPA can issue enforcement notices.; Planning permission usually expires after 3 years if not commenced.; Building Regulations approval is separate from planning permission — you may need both.. If you're unsure on any of these, get advice from a regulated solicitor or a free service like Citizens Advice before acting.
- Where can I find the official forms and guidance?
- The official sources are: Planning Portal; Planning Inspectorate — Appeals. Always use the forms / guidance from the issuing authority's own site — third-party copies can be out of date.

- Yes — many people complete this kind of matter as a litigant in person. The site walks through each step in plain English. A solicitor is recommended if: large sums are at stake, the other side has legal representation, the matter involves criminal liability, children, immigration, or you're unsure on any procedural deadline. Free advice is available from Citizens Advice, Law Centres, and (for some matters) LawWorks pro bono clinics.
