Understand your challenges
Ensure compliance
Stay ahead of biodiversity net gain legislation. We provide end-to-end support, ensuring compliance from planning through development and for 30 years beyond.
Integrate and manage strategies
Align biodiversity net gain with nature-based solutions, nutrient neutrality, and ESG goals. We help manage costing, ownership models, and long-term monitoring plans for sustained success.
Enhance climate resilience
Ensure species selection supports long-term biodiversity by adapting to climate change challenges, including rising temperatures, changing precipitation patterns, and habitat shifts.
What is biodiversity net gain?
Under the Environment Act 2021, all new developments in England must deliver at least a 10% net gain in biodiversity, ensuring that nature is left in a better state than before. This is measured using Defra’s biodiversity metric, which assesses the impact on habitats and wildlife.
Developers must enhance biodiversity either on-site or through off-site improvements, with all gains legally secured and maintained for at least 30 years. If on-site improvements are not feasible, biodiversity credits can be purchased to meet the requirement.
Biodiversity net gain is now a crucial factor in planning applications, affecting developers, landowners, and businesses. Ensuring compliance not only meets legal obligations but also supports

How we can help
Ensure your project meets Biodiversity Net Gain regulations while enhancing sustainability. Our expert-led services cover assessment, consultancy, and strategic planning, helping you achieve and exceed the required 10% Biodiversity Net Gain.
Assessment surveys
We conduct detailed baseline assessments and habitat condition surveys using the official biodiversity metric to establish accurate score baselines. Following the assessment, we provide a comprehensive report with tailored recommendations to ensure compliance with regulatory requirements.
To future-proof your biodiversity strategy, we model climate change impact to ensure species selection remains resilient against:
- Rising temperatures and heatwaves
- Changing precipitation patterns
- Sea level rise
- Increased frequency and intensity of storms
Our assessments cover a wide range of critical areas, including:
- UKHab and biodiversity condition assessments
- Biodiversity Net Gain assessments for developers and landowners
- Comprehensive land-based surveys (soils, topography, and land use) to ensure feasibility and long-term sustainability
- Hydrological assessments (water balances, water level management, and silt management planning)
- Climate resilience modelling and species adaptation reports
