Learn More About our Available BNG Units

BioMark owns and manages an expansive network of habitat banks. Our specialist land managers are transforming over 1,100 acres of low-productivity land into biodiverse havens. At BioMark, we strive to minimise costs for developers by providing the lowest cost BNG units whilst delivering real benefits to regional biodiversity.

Benefits of Buying BNG Units With BioMark

Nature Walk
  • Developers and consultants who source biodiversity units from BioMark unlock a streamlined pathway to ecological compliance. They immediately access ready-made biodiversity projects and swiftly achieve biodiversity net gain compliance without the complexities faced by on-site gains.

  • Our experienced habitat bank land managers handle long-term habitat monitoring, shifting risk away from consultants and developers. The 30-year management obligation is passed from the developer to the unit provider. 

  • Ongoing management of on-site BNG on a housing development must be funded by the residents. This can negatively impact the sale value of the homes. By offloading risk to off-site unit providers like BioMark, ground maintenance fees are largely reduced. 

  • Buying our off-site biodiversity units allows architects and developers to produce a straightforward Biodiversity Gain Plan, expediting the approval process with local planning authorities.

Calculating BNG Requirements

Calculating BNG requirements starts by establishing the pre-development biodiversity value through habitat surveys. Then, forecasting the post-development biodiversity value using the Defra Biodiversity Metric 4.0 (or a simplified version for small sites). Due to the complexity of the biodiversity metric, input from ecologists and land managers is crucial for accurate calculations

Buying BNG Units

When the calculation shows a difference between pre- and post-development biodiversity values, it determines whether your project will result in a net gain or loss. If your project results in a biodiversity net loss, you can easily purchase BNG units from BioMark to comply with legislative requirements. However, it is essential to note that you must purchase the correct units: The Statutory Biodiversity Metric
