Invest in High-Integrity Biodiversity Net Gain in Wiltshire

Great Chalfield is part of a long-term vision to restore nature across a working farm landscape and that vision needs investment

By investing in Great Chalfield, you are supporting the transformation of a 140-hectare farm into a thriving, nature-rich landscape demonstrating how farming, water, and wildlife can work together.

Biodiversity Net Gain (BNG) is a mandatory requirement for developers to ensure that the natural environment is left in a measurably better state than it was before development. By purchasing WWT BNG units, developers and investors can directly fund the long-term restoration of Wiltshire’s precious habitats.

Wiltshire Wildlife Trust  offers a high-integrity, trusted solution  for off-site BNG requirements. We offer a seamless, legally robust pathway for developers to meet their obligations while delivering genuine, local ecological impact  delivered by Wiltshire Wildlife Trust in partnership with the National Trust.

• High Integrity: Our units are backed by the Wildlife Trust brand, ensuring your investment delivers measurable, lasting ecological value.
• 30-Year Security: All BNG sites are legally and financially secured for a minimum of 30 years, managed by our expert ecology teams with clear management plans and monitoring in place
• Mosaic of habitats: We currently have a 60 BNG units available across a range of habitats, including:
   – Deciduous woodland
   – Individual trees
   – Mixed scrub
   – Other neutral grassland
   – Watercourse units
• Local Impact: We ensure your investment supports nature recovery in Wiltshire, benefiting the communities where you build.
• Independent Oversight: The credits available are overseen by Hampshire and Isle of Wight Wildlife Trust (HIOWWT) as our official independent Responsible Body,  they make sure the credits we are offering will deliver what we say they will for nature.

This range allows buyers to select units that best meet their project requirements, while contributing a wider, joined-up habitat mosaic across the farm and wider landscape.

We provide the full framework—legal, financial, and ecological—so you can secure units with confidence and be part of a flagship nature recovery project.
