The Biodiversity Net Gain Experts

BNG, simplified.

What is Biodiversity Net Gain?

BNG is a forward-looking approach to development that aims to enhance and restore biodiversity, while generating income for landowners.

A brief introduction…

New UK legislation within the environment Act requires all new developments to increase a sites biodiversity value (measured in Biodiversity Units) by at least 10%. This can be done by creating or enhancing existing habitats on-site, off-site, or by purchasing units from local landowners.

This presents opportunities and implications for both developers and landowners.

For Developers:

  • Developers must carry out a baseline metric calculation

  • A minimum of 10% BNG must be factored in to strategy and design stages, and opportunities for on-site increase/enhancement identified.

  • A BNG plan has to be submitted along with planning applications or upon planning consent.

  • If off-site mitigation is necessary, developers will need to purchase biodiversity units to make up the defecit.

For Landowners:

  • Landowners can offer land parcels for enhancement to support off-site mitigation.

  • Land can generate biodiversity units, which developers can buy to support BNG targets.

  • Landowners must commit to a management/monitoring plan for an agreed time period.

  • The value of land parcels are calculated on a case-by-case basis, and covers maintenance costs, as well as a portion of profit.

How can Bioland help?

We have a growing network of habitat banks to support developers meet their biodiversity requirements.

  • BNG will be mandatory from November 2023.

  • A sites biodiversity value is measured in biodiversity units. This is calculated by identifying which habitats are there, what type, and how much.

  • DEFRA estimative that biodiversity units can range between £9000 and £15000, and potentially up to £20000.
