Purchasing biodiversity units

With over a decade at the forefront of Biodiversity Net Gain (BNG), we help developers meet their obligations with clarity and confidence. We have supported the establishment of more than 30 habitat banks across England and our proven track record and deep planning expertise make us trusted leaders in this evolving market.

We hold exclusive brokering mandates on several registered sites and have a substantial pipeline of sites in development to continue expanding our coverage.

Our national network of habitat banks offers a clear route to securing off-site BNG. Our extensive experience in the site registration and unit allocation process gives purchasers confidence that we provide credible solutions and can guide them through the process.

Bespoke biodiversity solutions

Our significant portfolio of landowning clients across the country and our extensive experience in developing habitat banks enables us to provide bespoke solutions to meet large-scale and niche BNG requirements.

Having overseen the development of over 30 BNG schemes from conception through to implementation across the country, we are able to provide realistic timelines to give you assurance on the solution.

Utilising surplus biodiversity units

Where developments create surplus biodiversity units, we help unlock their value. We can help structure planning obligations to enable the sale or allocation of biodiversity units to other schemes and assist with the marketing and sale of biodiversity units to third-parties where appropriate.

We can also advise on suitable parties to deliver the physical works and ongoing management, including negotiating appropriate contracts and payment structures, which is integral to the success of an environmental scheme.
