Most developments in Nottinghamshire now require a mandatory 10% biodiversity net gain under the Environment Act 2021.
Local planning authorities expect clear baseline data, a defensible Metric 4.0 calculation and a proportionate uplift strategy before your application can progress.
Across Nottinghamshire, the type and depth of ecological evidence requested by planners is often shaped by recurring landscape characteristics:
river corridors and floodplain habitats along the Trent and Idle
brownfield regeneration sites around Nottingham, Mansfield and Worksop
hedgerow-dominated agricultural land in rural districts
mixed woodland and pasture near Sherwood Forest
canal and waterway networks with linked habitat corridors
edge-of-settlement growth around Nottingham, Newark and Retford
Regardless of site location, early confirmation of baseline value and realistic uplift options helps maintain a clear and defensible planning process.
We work throughout Nottinghamshire, including Nottingham, Newark, Mansfield, Worksop and nearby towns and villages.
Nottinghamshire LPAs request BNG evidence early because many developments sit close to watercourses, settlement edges or regeneration land, where small layout changes can noticeably affect habitat value and connectivity.
Officers want verified baseline habitats and clear Metric 4.0 scoring before designs progress, so uplift options can be understood without late-stage compromise. The county’s focus on canal corridors, historic field patterns and woodland-edge mosaics also means uplift feasibility needs to be established upfront.
On the ground, site-level features signal when BNG evidence will be needed:
Providing this clarity early prevents validation queries, redesign instructions and delays during casework.
We produce planning-ready BNG Assessments aligned to Nottinghamshire’s policy expectations.
Every report includes:
verified UKHab habitat mapping
defensible condition and distinctiveness scoring
full DEFRA Metric 4.0 calculation
uplift strategy shaped around LPA priorities
integration with layout, drainage and protected species
clear, structured reporting for validation and negotiation
Year-round, with botanical elements best May–September.
Completed once habitat data is verified.
Aligned with design progression and layout refinement.
Used where additional clarity is needed around baseline or constraints.
Our approach keeps evidence proportionate, technically robust and predictable through the full planning sequence.
Contact us and we’ll confirm exactly what your site requires and support a planning-ready, proportionate route forward.
In Nottinghamshire, BNG assessments are required to demonstrate compliance with national planning policy where development affects habitats such as hedgerows, watercourses, grassland, or woodland edges.

BNG is triggered in Nottinghamshire for most major and many minor developments where habitat loss or change occurs as part of the proposal.
Hedgerow networks, drainage ditches, river corridors and semi-improved grassland frequently influence BNG outcomes in Nottinghamshire.
In many cases, on-site delivery is achievable in Nottinghamshire through landscape-led design and early baseline mapping.
A clear BNG assessment gives planners confidence that biodiversity impacts are understood and mitigation is secured.
BNG assessments should be prepared by competent ecologists using the latest DEFRA metric.
