Typical BNG unit prices for every part of England. Brought to you by Biodiversity Units UK.

Indicative market estimates based on delivery within the NCA or LPA, from our latest quarterly BNG Pricing Report. Supplier prices can vary. Where local supply is limited, out-of-area delivery may apply, which could affect pricing through the spatial risk multiplier. Units are subject to availability. Habitats in your area may be in demand, so we recommend reserving units early. Prices as of 26 October 2026, per unit, + VAT.© 2026 Biodiversity Units UK
