Typically, landholdings need to be in excess of 10 hectares in total (but can be much larger) and suitable for creating new habitats and/or substantial enhancement of existing habitats.
The habitat improvements must usually be secured for 30 years through legal agreements such as conservation covenants or planning obligations.
A Habitat Management and Monitoring Plan (HMMP) to show how the biodiversity gain will be achieved and maintained over the 30 years will also need to be produced.
As of 2024 in England, land used for off-site biodiversity gains must be registered on a national register maintained by Natural England.
Habitats in particular demand include woodland, riverbanks, wetlands and arable land.
Landowners can expect to receive from £10,000–£45,000 per unit per year, depending on habitat type and location.
