Green Belt land checker
Find out whether a location in England is recorded within the Green Belt, and what national policy allows on land that is.
Check Green Belt status
Enter a postcode, address or place name in England. The check queries the national planning datasets published on planning.data.gov.uk and reports what is recorded at that point. It is decision support, not a planning decision.
Is my land in the Green Belt?
Green Belt boundaries are defined by local planning authorities in adopted Local Plans and published nationally as open data. The check above queries that national dataset for the point you enter and reports whether a Green Belt parcel is recorded there, alongside the other designations that most affect Green Belt cases.
Boundaries are sometimes tightly drawn around existing development, so a property can sit outside the Green Belt while the field behind it sits inside. Always check the parcel rather than the postcode centroid where the answer matters.
What Green Belt policy actually restricts
National policy treats most new buildings in the Green Belt as inappropriate development, which should be refused unless very special circumstances clearly outweigh the harm. It is a policy restriction on openness and permanence, not a landscape quality designation.
There are defined exceptions, including agriculture and forestry buildings, appropriate outdoor sport and recreation, limited extensions and replacement buildings, limited infilling in villages, affordable housing exception sites, and redevelopment of previously developed land that does not substantially harm openness.
Routes that do exist for Green Belt land
Green Belt land is not undevelopable. The realistic routes are:
- One of the policy exceptions, where the proposal genuinely fits.
- Grey Belt — land that does not strongly contribute to Green Belt purposes (a), (b) or (d), subject to the golden rules.
- Release through a Local Plan boundary review where exceptional circumstances are demonstrated.
- Very special circumstances on an application, usually resting on acute housing land supply shortfall plus deliverability and wider benefits.
Why the authority's plan position matters here
Under the NPPF (August 2026), authorities that cannot meet identified need without it are expected to review Green Belt boundaries. Whether an authority is at that point — and whether its five-year housing land supply and Housing Delivery Test are healthy — changes the prospects for Green Belt land more than almost any site characteristic.
Common questions
- How do I find out if land is in the Green Belt?
- Check the national Green Belt dataset published on planning.data.gov.uk for the parcel, as the checker on this page does, and confirm against the authority's adopted policies map.
- Can you build houses on Green Belt land?
- Only in defined circumstances: a policy exception, Grey Belt land meeting the national tests, land released through a Local Plan review, or a case supported by very special circumstances.
- Does Green Belt mean the land is protected for its landscape?
- No. Green Belt exists to keep land permanently open around built-up areas. Landscape quality is protected through National Landscapes and National Parks, which are separate designations.
