Your BNG journey as a Developer

Achieving Biodiversity Net Gain (BNG) is now a key part of development in England. Follow these simple steps to meet the 10% biodiversity increase requirement efficiently with biounit trader.

Step 1: Check If You're Exempt

Not all developments need to meet BNG rules. Check the rules to see if your project qualifies for an exemption.

Step 2: Choose Your BNG Strategy

If your development isn't exempt, you must achieve 10% biodiversity net gain. This can be done in three ways:

  • On-site improvements – Enhancing habitats within your development area.
  • Off-site purchases – Buying biodiversity units from landowners.
  • Statutory credits – A last resort, as these government credits are costly.

BNG habitats must be maintained for at least 30 years through legally binding agreements. If your project already includes habitat improvements, these may count towards your BNG target, reducing off-site unit needs.

With biounit trader, easily find off-site biodiversity units using filters like region, habitat type, and location. If nothing is available, set up a watchlist to get alerts when units are listed.

Step 3: Assess Your Biodiversity Impact

Understanding how your development affects biodiversity is crucial. A biodiversity metric tool measures your site's biodiversity before and after development. Larger projects require a qualified ecologist, while smaller ones can use the Small Sites Metric (SSM).

biounit trader connects developers with certified ecologists to ensure accurate calculations. Key factors assessed include habitat size, quality, and strategic importance.

Step 4: Secure and Register Your BNG Units

If you need off-site biodiversity units, biounit trader helps you find and purchase them from registered landowners. Before finalizing the purchase:

  • The landowner must commit to maintaining the units for 30 years.
  • Developers must register the allocation of off-site units on the Biodiversity Gain Sites Register.
  • Ensure all agreements are legally documented.

Finalising Your BNG Plan

Once you’ve secured biodiversity units, submit your Biodiversity Gain Plan as part of your planning application. The Local Planning Authority (LPA) has eight weeks to approve or reject it. Be sure to include your Biodiversity Gain Site Number from the register.
