West Yorkshire BNG advice
Biodiversity Net Gain in West Yorkshire
Plan your West Yorkshire development around its habitats, local planning policies and biodiversity net gain requirements.
ACP Consultants can help with habitat surveys, biodiversity metric calculations and a practical BNG delivery plan for your West Yorkshire site.
Local planning guidance
When does mandatory Biodiversity Net Gain apply?
In England, eligible development normally has to achieve at least 10% statutory Biodiversity Net Gain. This applies throughout West Yorkshire, subject to the correct exemptions and transitional rules.
The law changed on 6 August 2026. New planning applications on development sites of 0.2 hectares or less may be exempt where no onsite priority habitat is affected. Certain entirely temporary developments of five years or less can also be exempt. The former dedicated exemption for self-build and custom-build development ended for new applications made from that date.
These conditions are not a general exemption for every small building. Check the full red-line site area, affected habitat, application date and any section 73 history.
Householder development, the de minimis rule and other exemptions have their own legal definitions. Even where mandatory BNG does not apply, planning decisions may require ecological surveys or mitigation under separate species and protected-site laws.
See our BNG exemptions guide or the current government BNG guidance.
Local planning guidance
Which planning authority covers a West Yorkshire development?
West Yorkshire Combined Authority coordinates the city-region's LNRS and regional programmes. However, it does not normally determine individual housing or commercial planning applications. These go to the appropriate metropolitan district council or, within its boundary, the National Park Authority.

Local planning guidance
What biodiversity policies apply in Bradford?
Bradford's 2017 adopted Core Strategy remains part of the statutory development plan alongside applicable saved and local policies. It includes EN2 Biodiversity and Geodiversity and protection of the South Pennine Moors and wider ecological assets.
A replacement Bradford District Local Plan 2025–2043 has reached Regulation 19 consultation. Formal representations are being accepted from 19 October until 5 pm on 30 November 2026.
The new plan contains biodiversity, climate and green-infrastructure proposals. However, the draft will only become the adopted development plan after submission, examination and formal council adoption.
A Bradford application may also need to address the South Pennine Moors Special Protection Area (SPA) and Special Area of Conservation (SAC), including relevant recreational, ecological, hydrological or other impact pathways.
Do not present a proposed 2026 Bradford policy as an adopted new BNG threshold. Start with current national law, operative adopted policy and the relevant site allocation.

Local planning guidance
What does Calderdale require for biodiversity and BNG?
Calderdale adopted its Local Plan on 22 March 2023. Policy GN3 Natural Environment expects development to design in wildlife, follow the mitigation hierarchy and secure measurable biodiversity improvements in line with current guidance.
The council then adopted a Biodiversity Net Gain Supplementary Planning Document on 24 July 2024. It provides local guidance on ecological evidence, strategic significance, onsite and offsite delivery, significant habitat enhancement and monitoring.
This SPD supports the adopted plan. It does not override later national exemptions, current statutory metric guidance or separate protected-site duties.
Calderdale adopted its Biodiversity Net Gain Supplementary Planning Document on 24 July 2024.
A project near the River Calder, upland moorland or Local Wildlife Sites may require more than a generic habitat-unit worksheet. Also consider site design, flood risk, water quality and protected species.
Local planning guidance
What do Kirklees planning policies say about BNG?
Kirklees adopted its Local Plan on 27 February 2019. Policy LP30 Biodiversity and Geodiversity supports protecting and improving ecological networks, avoiding impacts and achieving measurable gain.
Kirklees also published a Biodiversity Net Gain Technical Advice Note in 2021. It helps explain habitat survey, the Wildlife Habitat Network and ecological design. However, the 2021 advice predates mandatory BNG and subsequent national reforms.
In March 2024, the council approved changes to its national application validation requirements following BNG commencement. Its current applicant BNG guidance requires applicants to establish the correct exemption position, baseline and metric where applicable.
A separate National Park planning boundary
The new Kirklees Local Plan preparation documents explicitly exclude land inside the Peak District National Park. The Park Authority decides relevant development applications there.
Kirklees began its replacement Local Plan under the 2026 plan-making system on 30 October 2026. Its consultation ran in August–September 2026, so it is early-stage preparation, not an adopted successor to LP30.
For planning applications, use the adopted 2019 policies and current authority checklist. Check moorland and designated-site effects separately.

Local planning guidance
Which Leeds biodiversity policies are actually in force?
Leeds currently determines applications using its adopted Local Plan documents. These include the Core Strategy and selective review adopted in 2019, the Site Allocations Plan, Natural Resources and Waste Local Plan, relevant saved policies and made neighbourhood plans.
The adopted planning framework provides nature conservation and net-gain policies, including Core Strategy G8 and G9, alongside the Leeds Habitat Network and local green-infrastructure expectations.
Important: the older proposed G9 rewrite was withdrawn
A previously advanced Leeds Local Plan Update, branded “Your City, Your Neighbourhood, Your Planet”, contained a proposed replacement Policy G9 Biodiversity Net Gain and species-enhancement proposals.
That document was withdrawn in January 2025. Its specific new G9 wording, additional submission requirements or species-feature ratios must not automatically be described as adopted 2026 policy.
Leeds instead began preparation of a new Local Plan under 2026 regulations. Its formal notice was published 18 June 2026, with Gateway 1 on 19 October 2026. The council's published timetable currently anticipates adoption in March 2029, but that is a proposed milestone, not a decision.
Leeds also has current developer-facing BNG guidance. It discusses information for applications, significant onsite BNG and council monitoring. However, any older blanket exemption or onsite-first description must be checked against the 6 August 2026 national changes.

What are Wakefield's current planning and BNG requirements?
Wakefield adopted its replacement District Local Plan 2036 on 24 January 2024. The adopted policies include:
| Adopted Wakefield policy | Primary role | BNG relevance |
|---|---|---|
| SP23 Design, Safety and the Local Environment | Primary roleIntegrate environmental design and local surroundings | BNG relevanceIdentify appropriate environmental and habitat opportunities early. |
| LP51 Ecological and Geological Conservation | Primary roleProtect habitats, species and geological assets | BNG relevanceAvoid and mitigate harm before calculating proposed habitat gains. |
| LP52 Ecological Protection of Watercourses and Water Bodies | Primary roleWatercourses, lakes and river corridors | BNG relevanceConsider watercourse metric, hydrology and condition assessment where relevant. |
| LP53 Wildlife Habitat Network | Primary roleMaintain and extend ecological connectivity | BNG relevanceDesign appropriate green corridors and habitat links. |
Wakefield adopted its BNG SPD on 15 October 2024. It guides the statutory 10% process and local delivery expectations. The SPD is a material consideration, but current exemptions and national statutory guidance still apply.
Sites around the River Aire and former coalfield wetlands can contain mature wetland, grassland or woodland habitat. Their value must be surveyed rather than assumed from a development site's industrial history.

When was the West Yorkshire Local Nature Recovery Strategy published?
West Yorkshire Combined Authority approved and adopted the West Yorkshire Local Nature Recovery Strategy on 12 March 2026. Its publication decision took effect on 24 March 2026, and Defra recorded the strategy as published by 15 April 2026.
It covers Bradford, Calderdale, Kirklees, Leeds and Wakefield, and was developed with those councils, Natural England and the Peak District National Park Authority.
The LNRS consists of an explanatory strategy and an interactive Local Habitat Map. It identifies existing biodiversity assets, priority species and locations where specific measures could restore or connect habitats.
The regional strategy draws attention to moorlands, peat, clough woodland, wetlands, grassland, rivers, urban green/blue networks and the benefits of nature for flood resilience.
The Combined Authority's own map guidance states that 44.6% of the strategy area was mapped for potential measures. That figure describes a strategic modelling choice, not the proportion of a development site that must become habitat.
The map does not replace a field survey, create permission for habitat works or automatically restrict development. It helps identify where suitable projects can contribute to the wider Nature Recovery Network.
Read the published West Yorkshire LNRS and Local Habitat Map.
Local planning guidance
Can the LNRS improve a development's biodiversity-unit score?
The statutory metric includes a strategic significance factor. The West Yorkshire LNRS can inform this where the proposed habitat action matches a relevant mapped recovery measure.
West Yorkshire Combined Authority explains that suitable mapped, aligned actions may qualify for a strategic significance factor associated with a 15% uplift in the statutory metric. However, a higher score is not automatic.
| What you find | What it means | What to do before using it in BNG |
|---|---|---|
| Existing important wildlife habitat | What it meansA site has biodiversity or designation value that may require protection | What to do before using it in BNGCheck field surveys, statutory and local designations and avoid harm. |
| Mapped location-specific recovery measure | What it meansThe LNRS identifies a suitable place for a defined habitat action | What to do before using it in BNGCheck whether your proposed habitat intervention actually matches that measure. |
| Unmapped supporting measure | What it meansAn action may support nature recovery without a particular mapped parcel | What to do before using it in BNGUse for good habitat design; do not claim an automatic High strategic-significance score. |
| Site outside priority mapped measures | What it meansNature recovery can still be appropriate | What to do before using it in BNGAssess suitability and use metric rules; do not invent a mapped multiplier. |
| Protected-species priority | What it meansCertain birds, bats or other species need habitat and impact consideration | What to do before using it in BNGAssess species duties separately; a habitat metric does not replace licensing or survey. |
For an application, retain the date/version of the relevant map extract, parcel evidence and the reason for each strategic-significance input. Some map information may be incomplete or need field verification.
A site that scores better in the metric still needs a realistic habitat management plan.
Local planning guidance
What separate protected-site duties can affect West Yorkshire?
The South Pennine Moors Special Protection Area (SPA) and Special Area of Conservation (SAC) cover extensive moorland and upland habitats in and around West Yorkshire. Relevant development can affect protected birds, peatland, heath, blanket bog, water catchments or access pressures.
Bradford, Calderdale and Kirklees plans include ecological policies protecting these landscapes. Some Kirklees land also falls within the Peak District National Park, a separate statutory planning authority.
Where a development could have a likely significant effect on an internationally protected site, Habitats Regulations Assessment (HRA) may be required. Depending on the location, this can involve recreational disturbance, hydrology, air quality or other ecological pathways.
BNG units and HRA are not interchangeable. Buying offsite units or achieving 10% does not automatically satisfy the Habitats Regulations.
Confirm the assessment area and any mitigation contribution with the relevant planning authority for your site and proposal.
The correct planning authority must assess the real site, relevant designated features and any appropriate avoidance or mitigation.
Local planning guidance
What habitats should West Yorkshire projects consider?
Clough woodlands and upland rivers
In Calderdale and Kirklees, steep wooded valleys, upland streams and moorland edges can support ecological networks, flood resilience and protected species. Restoration needs suitable soil, hydrology and landscape management.
River Aire, Calder, Wharfe and tributaries
Watercourses link the industrial valleys, towns and rural catchments. River works can require a specialist river condition assessment and the metric's watercourse module.
Former coalfield wetland and open water
Around Leeds and Wakefield, former coal workings have become wetlands, lagoons, grassland, reedbeds and woodland. These existing habitats may have significant ecological value despite the site's industrial history.
Grasslands, hedgerows, trees and urban wildlife networks
Rural farmland, older woodland, urban trees, parks and fragmented meadows can provide essential ecological connections. Some are protected or difficult to replace.
Protected species
Bats, breeding birds, amphibians, badgers, water voles and other species may require appropriate surveys or licensing. Statutory BNG exemption does not remove their separate legal protection.
Site design rule: Survey and retain important habitats before relying on replacement habitat or purchased units.
Local planning guidance
West Yorkshire BNG: seven questions before you submit
This original worksheet helps you check the correct council, LNRS, baseline and gain-delivery route. It does not calculate units or determine a statutory exemption.
| Check | Evidence to record | Why it matters |
|---|---|---|
| 1. Identify the authority | Evidence to recordRed-line site, one of five metropolitan districts, or Peak District National Park land | Why it mattersEstablish the current adopted planning policies and local validation list. |
| 2. Test national applicability | Evidence to recordSubmission date, whole site area, priority habitat, major/non-major status and relevant earlier permission | Why it mattersApply the 6 August 2026 exemptions and transitional rules correctly. |
| 3. Establish habitats | Evidence to recordUKHab parcel survey, condition, hedges, watercourses, trees and ecological constraints | Why it mattersPrepare an appropriate baseline and metric modules. |
| 4. Check protected-site impacts | Evidence to recordSouth Pennine Moors SPA/SAC, SSSI, ancient woodland, protected species or river pathway | Why it mattersIdentify HRA and separate mitigation, not just BNG units. |
| 5. Match the LNRS | Evidence to recordCurrent West Yorkshire Local Habitat Map, specific measure and proposed intervention | Why it mattersTest strategic significance without an automatic 15% uplift. |

| 7. Plan long-term care | Evidence to recordLand manager, funding, legal security, monitoring, HMMP and gain-plan timing | Why it mattersSupport habitats for the relevant long-term management period. |
Decision: Where the local policy, baseline, mapped habitat action or protected-site pathway is uncertain, obtain ecological advice before finalising the metric.
Local planning guidance
What BNG information is needed with a West Yorkshire planning application?
For development subject to mandatory BNG, the national application-stage information normally covers:
- Whether the applicant believes the statutory biodiversity gain condition applies.
- The pre-development biodiversity value, using an appropriate published statutory metric and recording its version or date.
- Any earlier baseline date and reasons, where relevant.
- Details of habitat degradation and earlier values where applicable.
- A description of any irreplaceable habitat on the site.
- A scaled habitat plan showing onsite habitats and a north point.
A council can require additional necessary, relevant and proportionate local evidence under its published application validation list.
Leeds: The council's BNG developer guide discusses baseline evidence, significant onsite enhancement, delivery and local monitoring. Apply current national exemptions and statutory metric guidance to the proposed development.
Calderdale: Its adopted July 2024 BNG SPD describes validation and determination, metric evidence, significant onsite delivery and monitoring. Review the current application category.
Kirklees: National validation requirements were updated in 2024 and the council has a 2021 technical note. Some historic thresholds and exemptions in old documents must be checked against new national rules.
Wakefield: Apply the adopted 2024 BNG SPD alongside the local validation checklist and the current statutory rules.
Bradford: Check the current adopted-policy and live planning application list rather than importing requirements from its unadopted Regulation 19 draft.
Do not assume every exempt small application needs a complete metric or final HMMP at initial submission. For professional scope see our BNG assessment service and BNG habitat surveys.
Local planning guidance
Which biodiversity metric should be used?
The statutory biodiversity metric calculates habitat value before and after development, reflecting type, area or length, condition, strategic significance and delivery risks.
As at 8 November 2026, the latest government statutory metric is version 1.1.0, updated 3 November 2026.
GOV.UK states that any published statutory metric version can be used. Therefore, a council webpage referring generally to the latest tool should not be presented as overriding that national allowance. Earlier pre-statutory Biodiversity Metric 4.0 is not itself a statutory tool.
The separate Small Sites Metric is available only where the development and habitats meet its eligibility criteria. A low building count does not alone determine which tool applies.
Use the proper modules for area habitats, hedgerows and watercourses. Record the actual tool version, UKHab evidence, LNRS map action and any application-specific assumptions.
Our statutory biodiversity metric service and Small Sites Metric assessments explain the technical work.
Local planning guidance
Can West Yorkshire developments use offsite biodiversity units?
Potentially. Registered offsite units can help meet an eligible scheme's shortfall, provided they match habitat trading rules, location risk, legal security and actual allocation requirements.
For major development, the hierarchy generally prioritises appropriate onsite improvement before registered offsite units. For qualifying non-major applications made from 6 August 2026, onsite and registered offsite options can be considered at the same preference level. Statutory credits remain last.
Significant onsite and registered offsite gains generally require legally secured habitat management and monitoring for at least 30 years.
What does West Yorkshire Combined Authority do?
The Combined Authority is a recognised Responsible Body for biodiversity gain delivery. Its published LNRS guidance explains that it works with constituent councils, entering conservation covenants for some public-sector habitat banks while councils create or sell units and the Combined Authority monitors delivery.
That role is separate from determining a developer's planning application. Moreover, the existence of a programme or advertised bank does not prove any particular habitat units are registered, unallocated, legally suitable or currently available to buy.
Check the government gain-site register, specific unit type, legal allocation and price for the development. See our offsite biodiversity units guide and Habitat Management and Monitoring Plan service.
Local planning guidance
What do West Yorkshire's published nature-recovery projects show?
Local conservation and council partnership projects illustrate habitat restoration across West Yorkshire.
Calderdale and Kirklees: clough woodland restoration
West Yorkshire Combined Authority describes Landscapes for Water, a partnership restoring clough woodland along the South Pennine upland valleys.
Its areas include Ryburn and Baitings in Calderdale and Deanhead and March Haigh in Kirklees. Restoration aims to improve ecological connectivity, water quality, carbon storage and natural flood management.
These are programme aims and project descriptions. Do not describe every proposed woodland as already established or legally registered as a BNG gain site.
Leeds and Wakefield: restoring former coalfield landscapes
The RSPB's Fairburn Ings reserve illustrates the conversion of former coalfield features into open water, reedbeds, wet grassland and woodland.
Nearby St Aidan's Nature Park, on a former opencast mine site, provides another example of wetland, grassland, meadow and woodland habitat linked to mining restoration.
They demonstrate why existing post-industrial habitats can be ecologically valuable. Neither reserve is presented here as a confirmed available statutory developer offset bank.

What affects a West Yorkshire BNG quotation?
A proportionate assessment cost depends on site area, habitat types, survey effort, condition assessment, hedgerows, watercourses, protected species and the likely gain-delivery route.
| Work or payment | Why it may arise | Important difference |
|---|---|---|
| UKHab and statutory metric | Why it may ariseEstablish existing biodiversity and calculate the change | Important differenceConsultant survey scope; not a fixed council or per-unit rate. |
| Biodiversity Gain Plan and HMMP | Why it may ariseIdentify legally deliverable habitat enhancements and stewardship | Important differenceFinal gain-plan approval is normally after planning permission and before works start. |
| Registered offsite units | Why it may ariseMeet a valid habitat shortfall through registered allocated gains | Important differenceUnit types, stock, legal agreements, spatial risk and actual prices need checking. |
| South Pennine Moors HRA or other species assessment | Why it may ariseAssess protected habitat/bird impacts independently of BNG | Important differenceCannot be discharged just by buying statutory units. |
| Council legal or monitoring arrangements | Why it may ariseSecure and oversee significant gains where required | Important differenceAuthority and project-specific, not one universal West Yorkshire fee. |
For a permission subject to the BNG condition, the final Biodiversity Gain Plan is normally approved after permission and before development begins. A council may request proportionate draft habitat evidence earlier.
See our Biodiversity Gain Plan guide and BNG costs and pricing.
How ACP helps
First, confirm the route. We consider the site boundary, council, application date and likely ecology constraints.
Next, establish the evidence. We scope UKHab surveys, condition assessments, metric inputs and any species or watercourse surveys.
Then, assess the delivery. We identify practical habitat retention, enhancement, offsite shortfalls and management information for the appropriate planning stage.
Good early advice can help avoid unsuitable habitat commitments and missing evidence. However, the planning authority decides whether permission is granted; no consultant can guarantee an approval or exact number of units before survey.

West Yorkshire Biodiversity Net Gain FAQs
Is 10% BNG mandatory everywhere in West Yorkshire?
Qualifying development normally needs at least 10% statutory BNG across England. Exemptions, priority habitats and application dates matter. Separate council planning or protected-species requirements may apply even when statutory BNG is exempt.
Which West Yorkshire councils decide planning applications?
Bradford, Calderdale, Kirklees, Leeds and Wakefield generally determine applications in their areas. Within the Peak District National Park portion of Kirklees, the National Park Authority has statutory planning responsibility.
Has the West Yorkshire Local Nature Recovery Strategy been published?
Yes. West Yorkshire Combined Authority approved it on 12 March 2026. The decision took effect on 24 March, and Defra recorded publication by 15 April 2026. It covers all five metropolitan districts.
Does the LNRS map automatically give a 15% uplift?
No. Strategic significance depends on the actual relevant mapped action, location, proposed habitat intervention and current statutory metric rules. The map does not replace UKHab surveys or guarantee biodiversity units.
Is Bradford's 2026 Local Plan now adopted?
No. Bradford's 2025–2043 Regulation 19 consultation runs from 19 October to 30 November 2026. The adopted 2017 Core Strategy and applicable saved policies remain relevant until a replacement is formally adopted.
Was the Leeds Local Plan Update adopted?
No. Leeds withdrew the former “Your City, Your Neighbourhood, Your Planet” update in January 2025. Its proposed revised G9 wording is not automatically adopted policy. A separate new Leeds Local Plan entered Gateway 1 in October 2026.
Does Calderdale have an adopted BNG SPD?
Yes. Calderdale adopted its BNG SPD on 24 July 2024. It supports Local Plan Policy GN3 and explains local application evidence, biodiversity calculation, onsite/offsite delivery and monitoring.
Does Wakefield have its own BNG policy?
Wakefield adopted its District Local Plan in January 2024, including LP51–LP53 ecology and watercourse policies. It adopted a BNG SPD in October 2024. Both need to be read alongside current statutory exemptions.
Can small sites of 0.2 hectares or less be exempt?
Eligible new applications from 6 August 2026 can be exempt where the complete site is no larger than 0.2 hectares and no onsite priority habitat is affected. Older applications and other exemption categories need their own checks.
Is South Pennine Moors SPA mitigation the same as BNG?
No. Internationally protected habitats and birds may require Habitats Regulations Assessment and separate mitigation. Achieving 10% BNG or purchasing units does not automatically resolve potential SPA/SAC effects.
Which statutory biodiversity metric should be used?
The latest government tool on 8 November 2026 was version 1.1.0, updated 3 November. GOV.UK permits any published statutory version, while the Small Sites Metric is limited to eligible schemes. Older pre-statutory Metric 4.0 is not an accepted statutory calculation tool.
What should I provide for a West Yorkshire BNG quotation?
Send the red-line plan, postcode, development description, drawings, existing ecological survey information and planning date. Mention known trees, streams, moorland or protected-site constraints.
