A registered off-site source of Biodiversity Net Gain units.
Under UK law, most new development must leave nature measurably better off than before it was built. Where a scheme cannot deliver that gain on its own site, it may purchase units from a registered off-site provider.
East Farm Habitat Bank is one of those providers. Our units are quantified under the statutory biodiversity metric and secured for a minimum of 30 years by conservation covenant.
From 2 November 2026, Biodiversity Net Gain also becomes mandatory for Nationally Significant Infrastructure Projects (NSIPs), which will need to deliver at least 10% BNG. East Farm Habitat Bank is positioned to supply units to NSIP schemes as well as standard planning applications.
Chalk downland and grassland habitats, at a range of distinctiveness levels.
Restoration across more than 80 hectares is creating a connected mosaic of habitats on the valley floor and its slopes, producing a quantified and registerable supply of units.

The land at East Farm Habitat Bank has been under the same ownership for over a century. The first farmland-to-nature restoration project took place over two decades ago, and new projects have been delivered at a steady rate ever since.
Bringing forward a habitat bank to supply statutory credits builds directly on that track record of long-term habitat delivery and management.
