Use This Before The Project Becomes Expensive
This resource is designed for early planning decisions. It helps you name the issue, record the obvious checks and avoid paying for drawings, applications or contractor commitments before the planning route is clear enough.
Good use
Print it, mark it up, save the source links and use it as a short agenda for a council, designer, consultant or builder conversation.
Not a decision
It is not a formal certificate, approval, legal opinion or replacement for checking the exact property, council and design.
Best next step
Use the planning decision tool when the checklist shows the route is still unclear or locally sensitive.
Work Through These First
- Write down the exact project and the part of the property it affects.
- Check whether the property is a house rather than a flat, maisonette or listed building.
- Look for conservation area, Article 4, planning condition or previous extension issues.
- Measure the proposal against the original house, not just the current layout.
- Consider a lawful development certificate if certainty matters before work starts.

Tick these off on paper or copy the text into your project notes. Keep any official links, screenshots and dates with the project record.
Before you assume permitted development applies
- Confirm the property type and whether domestic permitted development rights are available.
- Check whether earlier extensions, roof additions or outbuildings have already used allowances.
- Look for Article 4 directions, conservation areas, listed building status and planning conditions.
- Check height, depth, boundary and frontage rules for the exact project type.
Before spending money
- Save official source links and council pages checked.
- Keep measurements, sketches and photos with the checklist.
- Ask whether a lawful development certificate is worth applying for before work starts.
- Check building regulations separately from the planning route.
Things Worth Avoiding
- Treating permitted development as permission to ignore all planning limits.
- Measuring from the current house instead of the original house.
- Forgetting that local controls can remove or narrow the simpler route.
- Mixing up planning permission, lawful development certificates and building regulations approval.
Questions To Put To The Council Or A Professional
- Which exact permitted development class would this rely on?
- Has anything removed or limited those rights at this property?
- Would a lawful development certificate be sensible before works or sale?
Official Sources Worth Opening Next
Use these as starting points and then check the relevant council page for the property. Rules, validation requirements and local controls can change by authority and site.
Clean Citation Text
Use this when sharing the resource with a neighbour, designer, builder or adviser.
General Guidance Only
This checklist is general guidance and is not a formal planning decision.
Before relying on a borderline route, confirm the latest position with official sources, the local planning authority or a suitable professional.
