Biodiversity Units UK

We are Biodiversity Units UK, the UK's market leading BNG Unit broker. We work with developers, planning consultants and ecologists who want a fast response, straight talking partner who really understands Biodiversity Net Gain. In 2025 we facilitated 11% of BNG unit market transactions, making up 18% of allocations on the Natural England register. Our supply network covers 85% of the UK's habitat bank supply. So wherever you are building we can quickly source a range of unit supply options from the whole of the market. But we also solve harder problems: optimising designs to reduce unit costs, navigating complex planning conditions, and finding new solutions - all to save you money while meeting the requirements. We launched in 2023, one year before Biodiversity Net Gain (BNG) became mandatory for all new development in England. Our mission is to give you BNG Certainty - the right units, at the right price at the right time - so no delays in planning. Navigating Biodiversity Net Gain legislation shouldn’t take up too much of your time, erode your profits or delay planning. Since 2023 we've helped hundreds of clients secure compliant off-site units at competitive prices, acting as their commercially focused BNG partner. Our Matched Pricing means you are getting both great advice and the right price.
