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.
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).

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.
