ACP Consultants can help with habitat surveys, biodiversity metric calculations and a practical BNG delivery plan for your Dudley site.
Local planning guidance
Which planning authority covers a development in Dudley?
Dudley Metropolitan Borough Council is the unitary local planning authority for Dudley, Brierley Hill, Halesowen, Stourbridge and other borough settlements. Adjacent Sandwell and Wolverhampton use separate Local Plans. WMCA's LNRS spans the metropolitan area but does not decide ordinary housing applications.
Local planning guidance
Adopted and emerging planning policy
Start with the adopted policies and the actual site boundary. Then establish the evidence needed for the proposal and its planning stage.
The adopted Local Plan and biodiversity policies
The Dudley Local Plan to 2041 was adopted at Full Council on 13 July 2026. It is the borough's operative development plan. Its two parts cover strategic policies and local centres/site allocations, with relevant environmental policies across urban nature networks.
| Policy or development-plan document | Current adopted status | What it means for an applicant |
|---|---|---|
| DLP31 — Nature Conservation | Adopted 13 July 2026, statutory nature protection | Screen international, national and local designations and avoid or mitigate harm before applying metric gains. |
| DLP32 — Nature Recovery Network and Biodiversity Net Gain | Adopted 2026, qualifying development normally 10% BNG | Provide appropriate statutory metric evidence, match restoration to relevant recovery opportunities and design legally deliverable habitat. |
| DLP33 — Trees, Woodlands, Ancient Woodland and Veteran Trees; DLP34 — Hedgerows | Adopted 2026 vegetation protection | Retain established trees and hedgerow features and check replacement/management requirements. |
| DLP35 — Geodiversity and the Black Country UNESCO Global Geopark | Adopted 2026 geology and nature interest | Avoid harm to geological features and distinguish geology conservation from biodiversity unit calculations. |
| DLP36 — Canals and DLP46 — SuDS | Adopted 2026 water and blue-green infrastructure | Assess habitat connectivity, watercourse effects, drainage and long-term greening design where applicable. |
Adopted DLP32 addresses statutory 10% for qualifying proposals and connection to nature recovery. It must be read alongside 6 August 2026 national small-site exemptions and non-major gain hierarchy, as well as the 29 September 2026 NPPF, rather than using a 2023 consultation statement requiring every site to gain 10%. The council's adopted plan and actual policy map supersede earlier Regulation 18/19 drafts.
Which Local Plan proposals are still emerging?
The council commenced preparing yet another Dudley Borough Local Plan to 2041 under the new national plan-making system. It consulted on scope from 16 July to 10 September 2026, immediately after the adopted plan, and completed a Gateway 1 self-assessment. This is only preparation, not a second replacement adoption.
Future policy work will consider changed NPPF requirements, WMCA spatial strategy, employment and housing allocations, natural environment and infrastructure. The council explains that evidence and draft policies still need to be developed; do not quote an unconsulted new biodiversity target as legally operative.
Local planning guidance
Which Local Nature Recovery Strategy applies?
The West Midlands Local Nature Recovery Strategy was publicly launched 27 November 2025, with WMCA as the responsible authority. It covers seven metropolitan councils, including Dudley. Published priorities address urban habitat, woodland, watercourses, trees, wetland and landscape connectivity.
For Dudley, use the final mapped measures to inform habitat networks between ponds, canals, woodlands and former industrial land. The older Black Country Local Nature Recovery Network evidence may inform adopted DLP32, but the published WMCA LNRS now provides the statutory regional map. Only an appropriate matched mapped action can justify High metric strategic significance.
View the official nature-recovery source for its current publication status, actual mapped measures and applicable technical notes.
Local planning guidance
Local habitats and site considerations
Use habitats within and connected to your site to scope surveys and retain important ecological connections.
Fens Pools SAC and great crested newts
The Fens Pools Special Area of Conservation, also a Site of Special Scientific Interest, supports internationally important great crested newt populations and associated wetlands, pools, grassland and scrub. A development with a relevant impact pathway can need Habitats Regulations Assessment, habitat connectivity and species surveys independently of the BNG unit result.
Wren's Nest geodiversity and limestone grassland
Wren's Nest is a National Nature Reserve and important geological SSSI, with limestone fossil exposures and surrounding grassland and scrub. The adopted DLP35 geodiversity policy matters here; a BNG metric alone cannot protect geological interests or establish the condition of a separate plot.
Black Country canals, Saltwells woodland and brownfield
The Stourbridge canal network and wetlands connect industrial history with local woodland, ponds and green corridors. Saltwells Nature Reserve arose from coal-mining restoration. Former industrial plots may support valuable open-mosaic habitats, whereas fully sealed land may have lower measured baseline. Site-by-site UKHab and protected-species evidence is necessary.
A habitat being found elsewhere in the area does not prove it exists on the proposed development site. Existing priority habitats, species and condition must be assessed against the actual parcel and impacts.
Separate designated-site and planning obligations
Fens Pools SAC is a European protected habitat designation relevant to great crested newts. A relevant proposal may require Habitats Regulations Assessment, suitable habitat connectivity and species avoidance/licensing; a 10% BNG result cannot simply discharge a potential adverse effect on the SAC.
The Wren's Nest National Nature Reserve and Black Country UNESCO Global Geopark also contain protected geological features. Do not confuse biodiversity metric units with geodiversity protection. No universal Dudley per-dwelling SAC payment rate was verified, and a site must be checked against actual designated-site impact pathways.
A 10% biodiversity metric gain does not automatically discharge Habitats Regulations Assessment, protected-species licensing, nutrient restrictions or a specific local mitigation obligation. Scope those routes before assuming units will solve every ecological planning issue.
Local planning guidance
What local development and regeneration examples show
Dudley Council reported £944,444 of WMCA town-centre funding on 30 October 2026, linked to the Midland Metro extension, interchange, heritage and further investment. The first Metro services reached Dudley earlier in 2026, with further phases planned towards Merry Hill and Brierley Hill.
The metro corridor, disused railway and existing town-centre land provide concrete planning context for linear habitat connections, vegetation retention, drainage and construction ecology. However, a transport regeneration announcement does not establish a particular statutory Biodiversity Gain Plan, ACP consultancy involvement or legally registered units.
Local planning guidance
Are Dudley's listed BNG offsetting sites available to buy?
The council's earlier Regulation 18 Local Plan Part Two identified possible offset locations, including Barrow Hill, Buckpool, Saltwells Nature Reserve and Wren's Nest. The document expressly said its indicative list could change following survey and later plan stages.
It is not an independent government gain-site register, a dated available-unit stock list, or proof that habitats at a protected reserve can be sold to any developer. A proposal must confirm present actual registration, a legal agreement, unit type and allocation on the statutory register.
Protected-site duties at Fens Pools or a geological reserve also cannot be traded away simply because an historic draft plan mentioned an offset opportunity.
Local planning guidance
Ecological evidence for a planning application
Dudley Council's planning application page provides a Biodiversity Net Gain Validation Requirements Guidance Note and a local validation checklist reviewed in November 2024. These predate August 2026 exemptions, so the latest national statute must govern whether a BNG statement and metric are required for a particular application.
For a scheme near Fens Pools, old buildings, canals, mature trees, ponds or possible priority open-mosaic brownfield, ecological assessment and targeted species/HRA evidence may be needed alongside the national statutory BNG baseline. Different documents apply to major/minor/householder applications; the final Biodiversity Gain Plan is usually approved later.
For mandatory BNG, national application information normally includes an applicability statement, pre-development biodiversity value, completed statutory metric and tool version, any relevant earlier baseline or habitat-degradation explanation, irreplaceable habitat information and a scaled onsite-habitat map with north indicated.
For assessment scope see the ACP BNG survey guide and BNG assessment service.
Local planning guidance
Does statutory 10% BNG apply to this development?
Normally, qualifying developments in England must deliver at least 10% statutory Biodiversity Net Gain. Under reforms effective 6 August 2026, a new application for a whole development site of 0.2 hectares or less can be exempt if no onsite priority habitat is adversely affected. Certain wholly temporary developments of five years or less can qualify, and the former dedicated self-build/custom-build exemption was removed for relevant new applications.
Application date, section 73 history, the actual red-line site, development class, priority habitat and other exemptions matter. A small building or household proposal is not automatically subject to the same rules. The ACP exemptions guide explains the main decision process.
The 29 September 2026 NPPF N1(2)/N2(3) limits local compulsory BNG above the national minimum to specific, justified and deliverable site allocations. Do not assume a general 20% requirement from a withdrawn, superseded or emerging planning document.
Local planning guidance
How to calculate biodiversity units correctly
As of 10 November 2026, the latest government statutory biodiversity metric workbook is version 1.1.1, updated 10 November 2026. GOV.UK allows other published statutory metric versions where appropriate. Pre-statutory Metric 4.0 is not a valid statutory submission tool. The Small Sites Metric can be used only for qualifying smaller schemes.
DLP32 encourages nature recovery and the WMCA LNRS has been formally published since November 2025. Match the actual mapped measure and proposed habitat; no generic borough-wide High score. Fens Pools' protection is a separate HRA/legal issue, not permission to replace SAC habitat with metric units.
The calculator considers habitat type, extent, condition, strategic significance, creation/enhancement risk and separate hedgerow or watercourse units. An LNRS opportunity polygon alone does not guarantee a High multiplier. Read our statutory biodiversity metric guide or Small Sites Metric guidance.
Local planning guidance
Project planning and delivery
Build the planning evidence around a consistent habitat baseline, site layout and metric. The steps below connect the application documents with practical habitat delivery.
Onsite habitat, registered offsite units and delivery
Urban infill can limit onsite space, but connected canals, hedgerows, rain gardens or appropriately designed green roofs may provide valuable gains. For a remaining shortfall, legally registered and allocated offsite units can be used where the hierarchy and habitat trading rules permit.
Dudley's 2023 draft potential-offset site list is indicative only. Some locations are nature reserves or designated sites. No confirmed current quantity, registration, allocation or price was obtained; verify the government's gain-site register and current seller agreements before offering units as part of a development.
For major development the statutory hierarchy generally prioritises suitable onsite habitat creation/enhancement. For eligible non-major new applications from 6 August 2026, onsite and registered offsite gains may be considered at an equivalent hierarchy level. Statutory credits remain the last option.
Significant onsite and registered offsite gains usually need secure management for at least 30 years. A suitable Habitat Management and Monitoring Plan and a Biodiversity Gain Plan set out realistic establishment, legal security, management and monitoring. The statutory register confirms actual legally registered and allocated offsite units, not a supplier brochure.
For unit procurement principles, see offsite biodiversity units.
What affects BNG assessment costs?
Assessment scope depends on brownfield baseline, trees, demolition, protected species, canal or watercourse impacts and any designated-site HRA. The council's £944,444 town-centre regeneration grant is not a BNG fee.
Separate habitat survey/metric, any newts or HRA mitigation, section106/legal management, registered offsite units and long-term monitoring. No supported borough-wide fixed unit price or Fens Pools tariff is asserted.
Survey/metric fees, protected-site or species mitigation, legally secured offsite biodiversity units, authority/legal monitoring and long-term habitat management are distinct cost categories. No universal Dudley biodiversity-unit price or local council charge is asserted without a current source. Check the ACP BNG costs guide for typical cost drivers.
Local planning guidance
A documented local planning or nature-recovery example
Dudley Council's 30 October 2026 news records £944,444 WMCA funding for town centre transformation, complementing the 2026 Metro extension and regeneration works. This establishes a current development context including old rail and industrial corridors.
It is a public regeneration funding record, not a BNG scheme approval or conservation outcome. The practical lesson is to survey existing trees, channels and potentially valuable brownfield habitat early, then secure deliverable ecological design where the actual planning proposal affects those assets.
Your site checklist
Seven checks before submitting a Dudley BNG assessment
Use these seven checks to prepare a proportionate brief for your site assessment and planning submission.
| Check | What to collect | Decision supported |
|---|---|---|
| 1. Confirm the decision-maker | Confirm the red-line site against actual Dudley borough and planning-policy boundaries. The West Midlands metropolitan county is not the same as the wider West Midlands English region. Old planning documents titled Black Country Plan may remain evidence, but the separate Dudley Local Plan was formally adopted in July 2026. | Use the actual adopted planning policies and correct local validation list. |
| 2. Test national BNG eligibility | Full red-line area, application date, priority habitat impact, development type and any section 73 history | Check 6 August 2026 exemptions before assuming a metric is mandatory. |
| 3. Map existing habitat | UKHab parcels, condition, hedgerows, trees, watercourses and protected-species features | Select the correct baseline and appropriate statutory metric modules. |
| 4. Check nature recovery | West Midlands Combined Authority LNRS published 27 November 2025 — use its current official Local Habitat Map and site-specific proposed measures | Test strategic significance using actual published status and mapped habitat intervention. |
| 5. Identify special ecological duties | Fens Pools SAC great crested newts and wetland; Wren's Nest geology; canal/pond networks, trees, brownfield ecology and protected bats/birds. | Check separate HRA, licensing, nutrient or habitat protection before counting units. |
| 6. Plan a realistic gain | Onsite space, habitat trading and actual registered/allocated offsite units | Avoid relying on a marketing listing or assumed spatial-risk score. |
| 7. Secure management | Land manager, funding, legal agreement where required, HMMP and monitoring schedule | Prepare the relevant final gain plan and long-term management commitments. |

Dudley Biodiversity Net Gain FAQs
These answers cover common planning, habitat and delivery questions for projects in Dudley.
Which council determines a development in Dudley?
Dudley Metropolitan Borough Council is the unitary planning authority for Dudley, Brierley Hill, Halesowen and Stourbridge. Sandwell and Wolverhampton are separate LPAs with their own development plans.
Has Dudley adopted a new Local Plan in 2026?
Yes. The Dudley Local Plan 2041 was formally adopted on 13 July 2026. Its biodiversity and nature-recovery policies include DLP31 and DLP32, which must be read with current national statutory BNG rules.
Is Dudley preparing yet another plan?
Yes. A new-style Dudley Borough Local Plan commenced scoping 16 July–10 September 2026 and passed early Gateway1 preparation. It is not a second adopted replacement.
What does DLP32 require?
DLP32 covers the Nature Recovery Network and Biodiversity Net Gain. It expects qualifying development to deliver measurable statutory gain, normally 10%, and consider habitat connectivity and current national ecological safeguards.
Which LNRS applies to Dudley?
The published West Midlands Combined Authority LNRS, launched in November 2025. It covers the seven metropolitan councils and differs from the separate Warwickshire or Staffordshire strategies.
Can Fens Pools SAC be offset using a 10% BNG score?
Not automatically. Fens Pools SAC protects internationally important great crested newt interests. A development affecting the site may need Habitats Regulations Assessment, species licensing and avoidance independently of its metric units.
Are Wren's Nest and Saltwells on a list of BNG offset sites?
An older 2023 Dudley draft plan listed candidate offset locations, but it expressly described the list as indicative. A listing does not prove current government gain-site registration, unallocated units or permission to disturb a reserve.
What ecology might a Dudley brownfield scheme need?
Depending on the actual site, UKHab mapping, tree and hedgerow condition, bats and other protected species, ponds/newt or open mosaic habitat assessment may be needed. Industrial history does not itself make land low value.
Does Dudley have a blanket 20% BNG requirement?
Apply the national statutory requirement and any justified, applicable site-allocation requirement. National eligible development normally needs 10%, and September 2026 NPPF restricts higher compulsory local requirements to justified deliverable specific allocations.
Can sites of 0.2 hectares or less be exempt?
New applications made from 6 August 2026 can qualify for a conditional exemption where the whole red-line site is no more than 0.2 hectares and no onsite priority habitat is adversely affected. Transitions and other exemptions require checking.
When is the final Biodiversity Gain Plan approved?
For development subject to statutory BNG, the final gain plan is generally approved after permission before works begin. Council application-stage baseline metric and any necessary species reports are earlier.
What should I provide to ACP for a Dudley BNG quotation?
Send the site boundary, postcode, proposed use, drawings, planning deadline, ecology reports and information about trees, watercourses, ponds, older buildings or potential Fens Pools effects.
Talk to ACP / Site enquiries
What does your site need next?
Tell us where the site is, what you plan to build and how far the application has progressed. We’ll use that context to discuss the surveys, calculations or plans your project needs.
What to have to handA red-line plan, an existing ecology report or a request from the council can help us scope the work. Start with whatever you already have.
