Do you need a Biodiversity Net Gain Assessment in Stockport?

Biodiversity Net Gain is a required element of the planning process for most new developments. In practice, this means each scheme must show how it will increase biodiversity beyond the baseline recorded at the outset. Planning officers expect this information to be presented clearly, and applications are often delayed or left unvalidated when BNG evidence is incomplete or unclear.

Planning officers in Stockport often request BNG information where development may affect key habitat networks, such as:

• River corridors along the Mersey and Goyt

• Regeneration and former industrial sites with emerging habitat

• Urban parks, woodland edges and greenspace used for wildlife movement

• Valley systems and transport routes that act as linked habitat corridors

Clear and well presented BNG evidence helps avoid validation issues and delays in Stockport.

We support projects across the borough of Stockport, working in areas such as the town centre, Heaton Moor, Heaton Chapel, Reddish, Bramhall, Cheadle, Hazel Grove, Marple and the wider neighbourhoods within the Stockport local authority boundary.

Why planning authorities in Stockport request a BNG?

Stockport Council encourages applicants to address BNG requirements early in the design process so the planning team can be confident that the scheme can deliver the necessary uplift in biodiversity. This usually involves a confirmed ecological baseline, a completed Metric that sets out the change in biodiversity units, and a clear explanation of how the proposed gains will be created and secured for the long term. These expectations reflect national policy under NPPF Section 15 and help ensure BNG proposals stand up to detailed review.

Establishing the baseline at the outset reduces the chance of later amendments and supports a smoother passage through the planning system in Stockport.

Local Case Insight

A BNG assessment for a residential scheme in Marple uncovered unexpected habitat value along the boundary of a disused yard near the canal. A narrow strip of land that appeared unremarkable during early design discussions supported young scrub, tall herbs and a damp corner with soft rush and wet grassland, all contributing more biodiversity value than anticipated for a small urban fringe site. By refining the layout to retain this habitat band and adding new planting that linked the site to the nearby canal corridor, the project achieved the required net gain entirely within its boundary. This allowed the planning submission to move forward without delays and removed the need for off site units or changes to the design at a late stage.

How the BNG process works

We produce planning-ready BNG Assessments aligned to Stockport’s policy expectations.

Key BNG Deliverables for Stockport Projects

For developments in Stockport, our BNG assessments provide the key information planning officers require. Each assessment includes:

• a verified UKHab baseline

• a clear and justified Metric

• a workable uplift approach suited to the site

• planning ready reporting for validation

• optional long term management and gain plan material

This format meets Stockport Council expectations and offers a straightforward route to demonstrating BNG.

Step 1

Habitat baseline surveys

Year-round, with optimal survey seasons

Step 2

Metric 4.0 calculations

 Completed once habitat data is verified. 

Step 3

Uplift strategy development

Aligned with design progression and layout refinement.

Step 4

Integration with Other Surveys

Only if needed. PEA, EIA, and Protected Species surveys

FAQ - BNG in Stockport

Do I need a Biodiversity Net Gain assessment for development in Stockport?

Most developments in Stockport now require BNG evidence as part of the planning application. Stockport Council expects a clear baseline and a measurable uplift in biodiversity.

You can review local planning guidance here: 

Sites near the River Mersey, the River Goyt, local valley systems, former industrial land, parks, or transport corridors often require detailed BNG assessment.

As early as possible. Early baseline work reduces design changes later and supports smoother validation.

What does a BNG assessment include in Stockport?

It typically includes a UKHab baseline, a completed Metric, habitat mapping and a clear plan showing how biodiversity uplift will be achieved and secured.

Only in limited cases defined by national policy. Many smaller plots in Stockport still require BNG evidence due to local ecological considerations.

Off site biodiversity units within Greater Manchester may be used, and statutory credits are available when no other options are suitable.
