What is Biodiversity Net Gain (BNG)?­­

Developers in England are legally required to deliver at least 10% “Biodiversity Net Gain” (BNG) on new housing, industrial or commercial developments and small sites. This means that each development must leave nature in a better state than it was found by creating or improving wildlife habitats and maintaining them for 30 years. This should be delivered on-site within developments where possible, but if it isn't developers can "offset" their BNG by paying nearby landowners to deliver habitat creation and enhancement works on their land instead.

Working with us means you can play your part in delivering Kent Wildlife Trust's Wilder Kent 2030 strategy to restore healthy ecosystems across 30% of Kent's land by 2030.

Our Principles

With a 20+ year track record of designing and delivering biodiversity enhancements for clients across Kent, our BNG solutions can be trusted to reliably deliver significant long-term biodiversity uplift. Our BNG offsetting solutions are underpinned by Kent Wildlife Trust Group's high integrity principles, ensuring that maximum benefits are delivered for nature and protected in the long term.

the LNRS provides strategic guidance to help ensure that Biodiversity Net Gain (BNG) measures are delivered in offsite locations where they will contribute most effectively to wider nature recovery objectives. Aligning habitat creation or enhancement with the LNRS helps ensure that BNG delivers long-term, joined-up benefits for wildlife and supports Kent’s wider environmental priorities.

The right habitat in the right place

We choose the most appropriate habitat interventions to ensure our BNG offsetting solutions strategically support local nature recovery priorities and contribute to wider landscape-level conservation goals. This approach integrates the latest environmental research and is aligned with the conservation vision of the Kent Nature Partnership, which calls for a bigger, better and more joined up network of natural spaces across the county.

Maximising benefits for nature

Our BNG solutions go above and beyond to deliver 20% minimum uplift, and we avoid offsetting for irreplaceable or high distinctiveness habitats, or those important for local species populations. Where possible, we aim to create offset solutions that have recognisable wildlife value, with potential to become designated Local Wildlife Sites.

Sustainability

Our habitat management plans are developed with climate resilience in mind, and we consider how sites can deliver wider benefits to communities, such as reduced flood risk, air pollution barriers, and recreational opportunities.

Delivering a bespoke service

We consider the local nuances of each project and tailor our service to match each development with the best offset solution. BTF’s knowledge of rural land ownership in Kent and the Southeast is second to none, while our work with farmer clusters gives us a strong understanding of land management across the farmed landscape
