Campaign to change the ‘grey belt’ definition in the National Planning Policy Framework

August 21 2025

The Chesham Society is supporting an urgent change to the ‘grey belt’ definition in the NPPF. We think the grey belt glossary definition [which] could result in the loss of our countryside forever – vital for health and wellbeing, combatting climate change and supporting wildlife – needs revising.

‘Grey belt’ was initially described as poor-quality Green Belt land like disused car parks. We believe the new definition in the NPPF is so broad it could include almost any Green Belt land. The Green Belt prevents urban sprawl, protects nature & supports our health. We urge the Government to restore protections by ensuring that ‘grey belt’ proposals are judged against all 5 Green Belt purposes consistently throughout the NPPF to balance development needs against the many benefits of conservation.
