Biodiversity Net Gain (BNG) Surveys & Consultants: BNG in Hackney (London)
Biodiversity Net Gain (BNG) is now a key planning requirement for most developments in Hackney under the Environment Act 2021.
A BNG survey in Hackney establishes baseline habitat data and provides the biodiversity metric calculations needed to demonstrate measurable uplift within dense urban environments. Working with experienced consultants helps reduce validation delays, avoid redesign and support a clear, planning-compliant strategy. A BNG assessment applies DEFRA’s Statutory Biodiversity Metric 4.0 to compare pre- and post-development habitat value, ensuring that at least a 10% uplift is achieved through on-site enhancement or compliant off-site units. ACP Consultants delivers accurate, planning-ready BNG reports, supporting Biodiversity Gain Plans, habitat management and Section 106 agreements.

What is Biodiversity Net Gain (BNG): BNG in Hackney (London)?
Biodiversity Net Gain (BNG) in Hackney is a mandatory planning requirement designed to ensure that habitats end up in a measurably better condition after development. Most planning applications must submit a BNG survey in Hackney, including the baseline habitat condition, distinctiveness, and strategic significance. A BNG assessment in Hackney then models habitat losses and gains, showing how the required uplift will be delivered. In a borough dominated by compact streetscapes, infill developments, and mixed-use regeneration, BNG often relies on green infrastructure, planting, habitat restoration and rooftop habitat creation.
In Hackney, delivering Biodiversity Net Gain requires a carefully balanced approach due to the borough’s dense urban character and limited availability of open land. Many sites are constrained by existing buildings, infrastructure and high land use intensity, meaning that achieving biodiversity uplift often depends on integrating green infrastructure into the built environment. This can include biodiverse roofs, courtyard planting, green walls and sustainable drainage features that contribute to both habitat value and urban resilience.
Hackney also benefits from a network of parks, canals and ecological corridors, which can influence the strategic significance of habitats within the biodiversity metric. Enhancing connectivity to these features can improve biodiversity outcomes and strengthen planning proposals. Early ecological input is therefore critical to identify realistic opportunities and ensure that habitat improvements are both deliverable and aligned with local planning expectations.
By embedding biodiversity considerations into the design process from the outset, developers can create schemes that meet statutory requirements while contributing to long-term environmental quality across Hackney.
Environment Act & Local Policy in Hackney (London)
Hackney Council’s planning validation requirements expect clear and proportionate Biodiversity Net Gain evidence for qualifying developments. Submissions typically include baseline habitat surveys, statutory biodiversity metric calculations, and long-term habitat management commitments supported by a minimum 30-year stewardship approach.
In Hackney, this requirement sits within a highly urbanised borough where development pressures, regeneration and limited open space can constrain on-site biodiversity delivery. A Biodiversity Net Gain assessment translates existing habitat conditions into measurable units and demonstrates how uplift will be achieved through realistic, policy-aligned strategies.
Where sites cannot fully accommodate biodiversity gains on-site, developers may need to secure compliant off-site biodiversity units through verified providers. ACP supports this process by preparing robust metric calculations, Section 106 documentation, monitoring schedules and clear compliance statements. This ensures planning officers receive transparent, auditable evidence aligned with both national legislation and Hackney’s local planning framework.
DEFRA Metric 4.0
DEFRA’s Statutory Biodiversity Metric 4.0 underpins all BNG submissions in Hackney and provides the standardised method for measuring habitat value. The metric assesses habitat area, condition, distinctiveness and strategic significance to calculate baseline and post-development biodiversity units.
In a borough like Hackney, where sites are often constrained and highly urban, accurate metric inputs and realistic assumptions are critical. Our ecologists carry out detailed habitat mapping, condition assessments and green infrastructure planning to ensure that metric outputs reflect site-specific conditions.
We provide fully auditable metric spreadsheets, GIS mapping outputs and supporting narrative reports designed for planning officer review. This ensures that biodiversity calculations are transparent, defensible and aligned with both DEFRA guidance and Hackney’s planning expectations.

What is the best BNG in Hackney approach for constrained urban sites?
For compact or highly constrained sites in Hackney, delivering Biodiversity Net Gain requires a design-led approach that integrates biodiversity within the built environment. This often includes green roofs, biodiverse substrates, rain gardens, planting networks and habitat creation within public realm or rooftop spaces.
These measures can contribute significantly to biodiversity units while also supporting urban greening, climate resilience and sustainable drainage. In Hackney’s dense urban context, maximising multifunctional green infrastructure is often key to achieving the required uplift.
Where on-site delivery remains limited, developers may need to secure compliant off-site biodiversity units to meet statutory requirements. Early ecological input is essential to identify realistic opportunities, optimise design and ensure that the final strategy remains both deliverable and planning-compliant.

BNG Survey / Biodiversity Net Gain Surveys in Hackney
A BNG survey in Hackney establishes the baseline ecological condition of a site, including habitat type, condition and spatial distribution. Using UKHab classification and GIS mapping, our ecologists assess vegetation, trees, green infrastructure and urban habitat features to generate accurate biodiversity unit values.
In Hackney, surveys often need to address complex urban environments, including redevelopment sites, estates, canal corridors and fragmented green spaces. Early survey work helps identify constraints, highlight realistic enhancement opportunities and ensure that biodiversity net gain is built into the design process from the outset.
BNG Assessment / Biodiversity Net Gain Assessments in Hackney
A BNG assessment applies DEFRA’s Statutory Biodiversity Metric 4.0 to quantify habitat losses and gains. This includes modelling baseline conditions, post-development proposals and applying risk multipliers to demonstrate compliance.
In Hackney’s constrained urban context, assessments must balance development intensity with biodiversity delivery. Our reports include detailed metric tables, GIS outputs and clear justification for habitat enhancement or off-site solutions, ensuring alignment with local planning expectations.
BNG Action Plan (Hackney Projects)
A BNG Action Plan defines how biodiversity enhancements will be delivered during construction and early operational phases. It sets out responsibilities, sequencing, and site-specific measures to ensure habitats are implemented correctly.
In Hackney, this often includes integrating biodiversity within the built environment, such as green roofs, planting schemes and public realm enhancements. These plans help ensure that biodiversity delivery is practical, coordinated and aligned with construction logistics.
BNG Gain Plan (BGPs)
A Biodiversity Gain Plan provides the formal framework for demonstrating how biodiversity net gain will be achieved and maintained. It includes metric outputs, habitat proposals, off-site strategies and long-term management commitments.
In Hackney, BGPs must reflect both national legislation and local planning expectations, particularly for regeneration and high-density schemes. A clear and structured plan helps streamline validation and supports a smoother planning process.
Habitat Monitoring and Management Plan (HMMP)
An HMMP ensures that biodiversity gains are maintained over the long term through structured monitoring and management. It includes maintenance schedules, performance indicators and adaptive management measures.
In Hackney, where habitats are often integrated into urban design, long-term management is critical to ensure that green infrastructure continues to deliver biodiversity benefits. A well-prepared HMMP supports compliance and demonstrates long-term ecological stewardship.
BNG Report / Biodiversity Net Gain Report
A BNG Report consolidates survey data, metric calculations and habitat proposals into a single planning-ready document. It provides clear evidence of how biodiversity net gain will be achieved.
In Hackney, where sites vary from small infill developments to major regeneration schemes, reports must demonstrate that proposals are both realistic and policy-compliant. A strong report reduces validation delays and provides a clear audit trail for biodiversity delivery.
BNG Exemption Statement
Where BNG requirements do not apply, a BNG Exemption Statement provides clear justification aligned with statutory guidance. This is particularly relevant for smaller or low-impact schemes.
In Hackney, a robust exemption statement helps support planning validation, ensuring that biodiversity considerations have been appropriately addressed and clearly communicated to planning officers.
