What is Biodiversity Net Gain (BNG): Havering (London)?
BNG in Havering (London) requires developments to show at least a 10% gain in biodiversity, calculated through DEFRA’s statutory metric. Havering Council applies BNG to most major planning applications and increasingly to smaller schemes where biodiversity may be affected. A BNG survey quantifies current habitats, identifies losses and models future on-site or off-site enhancements to achieve measurable gains. These gains must be secured for 30 years by management and monitoring obligations, habitat delivery plans and potential legal agreements.
BNG in Havering (London) is directly linked to wider local policy goals including sustainable urban planning, nature recovery, habitat enhancement and improved green infrastructure. As part of London’s wider ecological strategy, the borough aligns with the London Plan’s emphasis on biodiversity offsetting, climate resilience, restoration ecology and environmental sustainability.
In Havering, Biodiversity Net Gain (BNG) is a key planning requirement that ensures development contributes to the borough’s ecological value. As an outer London borough with extensive green belt land, parks and semi-rural areas, Havering presents both opportunities and constraints for delivering biodiversity improvements.
BNG requires developers to demonstrate at least a 10% increase in biodiversity value, measured using DEFRA’s Statutory Biodiversity Metric. This involves assessing existing habitats, calculating baseline biodiversity units and designing enhancement measures such as habitat creation, restoration or improved management.
In Havering, proposals must also consider local ecological context, including habitat connectivity and long-term sustainability. Where on-site delivery is limited, off-site biodiversity units may be required.
Engaging a BNG consultant early ensures developments are designed efficiently, risks are minimised, and planning submissions align with both local policy and national biodiversity objectives.
Environment Act 2021 and Local BNG Policy in Havering (London)
Havering Council applies Biodiversity Net Gain (BNG) requirements in line with the Environment Act 2021, supported by the Local Plan and London Plan policies on green infrastructure and ecological enhancement. Most developments are expected to demonstrate measurable biodiversity improvements through planning submissions.
Typical requirements include a baseline habitat survey, DEFRA Metric 4.0 calculations, a Biodiversity Gain Plan and a Habitat Monitoring and Management Plan (HMMP) secured for at least 30 years. These documents must clearly show how development proposals deliver biodiversity uplift and long-term ecological value.
Given Havering’s extensive green belt, open spaces and semi-rural character, planning decisions often place strong emphasis on habitat retention, connectivity and sustainable land management.
Where on-site delivery is constrained, developers may need to secure off-site biodiversity units within Havering’s wider ecological network or through recognised providers. Early engagement ensures proposals align with policy expectations and reduce planning risk.
Using DEFRA’s Statutory Biodiversity Metric 4.0
DEFRA’s Statutory Biodiversity Metric 4.0 provides the framework for calculating biodiversity net gain in Havering. The metric assesses habitat distinctiveness, condition, connectivity, strategic significance and delivery risk to quantify biodiversity units before and after development.
A BNG survey establishes baseline habitat conditions, while the assessment models how design proposals achieve at least a 10% net gain. In Havering, enhancement strategies often include habitat creation along green belt edges, woodland and hedgerow reinforcement, wetland features and species-rich grassland.
Due to the borough’s mix of urban and semi-natural environments, achieving net gain may require a combination of on-site improvements and off-site unit provision.
ACP Consultants apply the metric transparently, using detailed habitat mapping and scenario testing to produce robust, policy-compliant outputs. We also integrate HMMPs, planning documentation and long-term management strategies to ensure biodiversity gains are deliverable and maintainable.

BNG Survey Biodiversity Net Gain Surveys in Havering (London)
classification and detailed habitat mapping. Surveys record habitat types, condition, extent and key ecological features, including trees, hedgerows, watercourses and urban green corridors.
In Havering, sites often include a mix of suburban land, garden habitats, grassland and edge-of-green-belt environments. Accurate classification is essential, as it directly influences biodiversity unit calculations and the feasibility of achieving net gain.
Our surveys provide robust, defensible baseline data that supports DEFRA Metric 4.0 assessments and informs early-stage design decisions. This helps developers understand constraints, identify opportunities and reduce planning risk.
BNG Assessment / Biodiversity Net Gain Assessments
A BNG assessment quantifies biodiversity value before and after development using DEFRA’s Statutory Biodiversity Metric 4.0. The assessment evaluates habitat distinctiveness, condition, connectivity and strategic significance to calculate biodiversity units and demonstrate compliance with the 10% net gain requirement.
In Havering, achieving net gain often requires careful integration of development layouts with habitat retention and enhancement, particularly near green belt land and ecological corridors.
We model multiple design scenarios to identify practical solutions, including habitat creation, enhancement and, where necessary, off-site biodiversity units. Our assessments provide clear, policy-compliant outputs that support planning applications and minimise delays.
BNG Report / Biodiversity Net Gain Report
A Biodiversity Net Gain Report consolidates survey findings, DEFRA metric outputs and planning justification into a single, structured document for submission to Havering Council.
Reports include habitat plans, baseline and post-development unit calculations, enhancement proposals and long-term management strategies.
We ensure all reports are clear, concise and aligned with local validation requirements, helping planning officers assess proposals efficiently and reducing the likelihood of further information requests.
BNG Action Plan
A BNG Action Plan sets out how biodiversity enhancements will be delivered on site, including habitat creation, planting strategies and ecological management measures.
In Havering, action plans must consider site-specific constraints, including land use, access, and long-term maintenance requirements. This is particularly important for developments near green belt land or areas with existing ecological value.
Our action plans provide practical, deliverable strategies that support both planning approval and successful on-site implementation.
BNG Gain Plan (BGPs)
A Biodiversity Gain Plan is a statutory requirement for many developments and must be approved prior to commencement or condition discharge.
In Havering, BGPs must clearly demonstrate how biodiversity net gain will be achieved, including baseline conditions, post-development units, habitat creation proposals and long-term management commitments.
We prepare compliant, planning-ready BGPs supported by robust evidence and DEFRA Metric outputs, ensuring alignment with both national legislation and local authority expectations.
Habitat Monitoring and Management Plan (HMMP)
A Habitat Monitoring and Management Plan (HMMP) outlines how biodiversity enhancements will be maintained and monitored over a minimum period of 30 years.
In Havering, HMMPs are critical to demonstrating that biodiversity gains are not only delivered but sustained over time, particularly in areas with ecological sensitivity or green belt influence.
Our HMMPs include clear management prescriptions, monitoring schedules and reporting requirements, ensuring compliance with planning conditions and long-term ecological success.
