Frequently asked questions

What's the difference between outline and full planning permission?
Outline planning permission establishes the principle of development (is housing acceptable here?) while leaving specifics like layout and appearance to later applications. Full planning permission includes all details upfront. Outline is typically followed by 'reserved matters' applications that fill in the specifics.
What are 'reserved matters' in a planning application?
Details that an outline permission left to be approved later. There are five reserved matters: access, appearance, landscaping, layout and scale. They must usually be submitted within 3 years of the outline permission being granted.
How long does a planning decision for a new home take?
Statutory targets are 8 weeks for minor applications (1-9 dwellings) and 13 weeks for major applications (10+ dwellings), measured from the date the application is validated. Complex cases or appeals can take much longer.
