FAQs
Frequently Asked Questions About Biodiversity Units
-
The best time to secure off-site biodiversity units is as early as possible in the planning process. Demand for verified BNG units is increasing, and sites are allocated on a first-come, first-served basis.
Key stages to consider BNG units:
Pre-application stage – Ensure your project aligns with local planning policies early.
Before submitting a planning application – Avoid delays by securing biodiversity units in advance.
Post-planning approval – If BNG is a condition of approval, act quickly to secure units before construction starts.
-
The biodiversity units you’ll require will depend on your development’s location, habitat impact and your Biodiversity Metric results. The metric assessment calculates the biodiversity losses from your project and will determine the type and number of units required to achieve the 10% net gain.
