How Can BNG Partnership Support NSIPs?

From 2 November 2026, Biodiversity Net Gain (BNG) becomes mandatory for all Nationally Significant Infrastructure Projects (NSIPs) in England. Under Schedule 15 of the Environment Act 2021, applicants submitting Development Consent Order (DCO) applications must achieve at least a 10 percent net gain in biodiversity for their site.

NSIPs benefit from tailored rules, such as the streamlined BNG boundary approach and the ability to source off-site gains directly without a strict spatial hierarchy, but securing large-scale, compliant off-site units remains a major operational hurdle.

At BNG Partnership (BNGP), we provide the scale, land management experience, and technical expertise required to ensure your BNG commitments are fulfilled smoothly and risk-free.

Decades of Planning Expertise

Navigating a DCO application requires managing complex regulatory requirements, and strict statutory deadlines. Our team brings decades of planning and ecological experience to your project.

We understand how to integrate off-site BNG into your outline biodiversity gain plan early in the pre-application phase. By aligning our processes with statutory metrics and DCO examination standards, we remove BNG friction points long before they can threaten your project timeline.

Generations of Land Management at Scale

Securing BNG for infrastructure developments requires land availability, security, and deep ecological roots.

BNG Partnership is built on generations of large-scale land stewardship. We already operate 5 registered statutory habitat banks across the country, with many more currently in development to meet expanding demand. You can explore our growing network on our Habitat Banks Page.

• 5 Registered Habitat Banks actively generating verified units.
• Growing Regional Network providing broad coverage across multiple Local Planning Authorities (LPAs) and National Character Areas (NCAs).
• Scalable Delivery capable of absorbing both localised habitat impacts and creating hundreds of new units for each project.

Demand-Driven: Tailored Habitat Banks Built for Developers

Off-the-shelf BNG units do not always fit the specific geographic or ecological profile of a large-scale project. BNG Partnership specialises in demand-driven, bespoke habitat banks designed around exact developer requirements.

• Polhampton Habitat Bank: Created exclusively for Persimmon Homes to directly address their BNG requirements in Hampshire. Read more about this project in our Polhampton Case Study. Polhampton demonstrates our capacity to acquire, register, and manage sites tailored to a single developer's requirements. We bring the same custom approach to NSIP infrastructure projects with specific regional or ecological needs.
• Boxworth Habitat Bank: Boxworth in South Cambridgeshire was created in response to a requirement from The Hill Group, and remains the second largest single allocation at any site on the Biodiversity Gain Site Register. By working in partnership with The Hill Group and South Cambridgeshire District Council (together known as SCIP), we built a tailored landscape which suited not just this development, but was built to match the needs of the local area. For more details, read our Case Study.

We can create custom, tailored habitat banks to match your scheme’s scale and type requirements.

Complete Legal and Compliance Management

Securing off-site BNG is not just about buying units; it is a 30-year commitment. BNG Partnership takes full responsibility for the entire lifecycle, removing ongoing risk from the developer.

• Legal Agreements & Paperwork: We handle Section 106 agreements, Conservation Covenants, and National Biodiversity Gain Site Registration.
• Planning Hurdles: We act as the bridge between developers, local planning authorities, and ecological inspectors to resolve planning conditions cleanly.
• 30-Year Stewardship: BNG Partnership takes full, legal, long-term responsibility for creating, enhancing, and maintaining the habitat over the statutory 30-year timeframe.

High-Quality Habitat Banks with Extensive Monitoring

For NSIP developers, reliable off-site delivery is essential to guard against enforcement actions or reputational damage over the 30-year term.

Our habitat banks are designed to exceed basic legislative requirements:

• Above-and-Beyond Monitoring: We have built in comprehensive, long-term ecological tracking to guide interventions and guarantee habitat improvement.
• Data-Driven Transparency: Extensive reporting makes sure that local authorities receive clear, indisputable proof of net gain compliance year after year.
• Ecological Integrity: Built on robust habitat management plans that prioritise biodiversity uplift, resilience, and local ecosystem restoration.
• Ongoing Visibility: Our in-house technology gives you oversight of your unit compliance for the full 30-year period.

Partnering with BNGP ensures your project satisfies statutory requirements while delivering real, lasting environmental gain. Explore our available locations on our Habitat Banks Page or contact our team to discuss bespoke solutions.
