The NPPF defines 'Grey Belt' sites as areas within the green belt that include previously developed land and other parcels that have a minimal impact on the green belt's primary goals. This excludes land or assets of particular significance, such as those with existing environmental protections.
According to this definition in the latest NPPF, Grey Belt sites must meet various criteria, including land use, designation, existing infrastructure, and local planning policies. However, this doesn’t mean they are impossible to identify.
In recent research, LandTech found that up to 150,000 ha could qualify as ‘Grey Belt’ and that between 2.5 and 4 million homes could potentially be built in these areas.
