Biodiversity Net Gain in Leominster
Plan your Leominster development around local habitats, planning requirements and practical biodiversity gains.
ACP Consultants can help with habitat surveys, biodiversity metric calculations and a practical BNG delivery plan for your Leominster site.
Local planning
Who decides planning applications in Leominster?
Herefordshire Council determines ordinary Leominster development. Leominster Town Council prepared and supports the made Neighbourhood Development Plan but does not determine most planning permissions. The planning boundary covers Leominster town and named parishes; nearby rural postcodes or villages may belong to other neighbourhood areas even while remaining inside Herefordshire unitary planning.
Check the actual site boundary
Leominster's town, Brierley, Ivington and Wharton areas have distinct neighbourhood-plan designations and site characteristics. Confirm the full red-line boundary, adopted neighbourhood policies, Lugg nutrient catchment, and protected watercourse zones rather than assuming every HR6 postcode has identical land designation.
Local planning
Adopted and emerging planning policy
Use the adopted development plan and the actual site boundary to establish the local policy context.
Herefordshire Local Plan Core Strategy 2011–2031 was adopted 16 October 2015. Its LD2 Biodiversity and Geodiversity, LD1 Landscape and LD3 Green Infrastructure provide operative ecology principles. LO1 Leominster and associated town growth policy address Leominster's strategic development. The Leominster Area Neighbourhood Plan was made 22 March 2019 and is part of the statutory development plan.
| Policy | Status and purpose | What to consider |
|---|---|---|
| Herefordshire Core Strategy 2011–2031 | Adopted 16 October 2015 | Use the operative county Core Strategy, actual site policies map and 2026 national BNG law. |
| LD2 Biodiversity and Geodiversity; LD3 Green Infrastructure | Adopted ecology and nature network policies | Avoid harm to designated habitats and protected species, retain/restore ecological networks, and justify feasible BNG delivery. |
| LO1 Leominster and relevant Leominster growth strategy | Adopted town settlement/urban growth policy | Check the actual town expansion/urban extension and allocation site before assuming habitat type or developer requirements. |
| Leominster Area Neighbourhood Plan | Made 22 March 2019, applies where mapped | Use LANP10 Green Infrastructure, LANP11 Open Spaces and LANP12 Greening the Town, plus site-specific settlement and housing rules. |
Under LD2, biodiversity networks, protected habitats and species need appropriate assessment independently of the 10% metric. The made Leominster plan adds LANP10, LANP11 and LANP12 for green infrastructure/open spaces/greening. An adopted neighbourhood green-space protection is not an interchangeable biodiversity offset allowance.
The replacement plan
Herefordshire stopped advancing its March 2024 Regulation 18 draft following national housing policy changes. The Council is now preparing a new Herefordshire Local Plan 2025–2045, with its current timetable under the revised 2026 plan-making system.
How to apply emerging proposals
The 2025–2045 notice and Call for Sites do not replace the 2015 Core Strategy and 2019 made Leominster Neighbourhood Plan. Planning permission for a Leominster development must be based on current adopted policy, up-to-date national BNG law and the actual application/permission status.
Nature recovery
Which Local Nature Recovery Strategy applies?
Herefordshire Council approved its Local Nature Recovery Strategy on 14 August 2026, with the final published plan released 21 August 2026. It records 37 biodiversity priorities and 100 potential measures/supporting actions, accompanied by a Local Habitat Map.
Relevant locally suitable measures might include River Lugg riparian buffer, restoring floodplain links, traditional orchards, hedgerows, meadow restoration or urban trees. Choose the exact action using the official mapped measure, site conditions and habitat survey. A restoration opportunity near Leominster does not itself guarantee an additional 15% biodiversity metric multiplier.
Local ecology
Local habitats and site considerations
Scope surveys around habitats within and connected to the site, and retain important ecological links.
River Lugg and Kenwater riparian networks
The River Lugg passes through the Leominster landscape and connects tributary channels and associated wetland areas, including the Kenwater. Land near actual waterways may need aquatic habitat condition, flood and otter/water vole or bird evidence. The river's nutrient/HRA requirements are separate from statutory BNG habitat units.
Traditional orchard, pasture, hedgerows and grassland
Rural Leominster sites can include agricultural margins, mature hedgerows, orchards and local meadow fragments. These may be priority habitats depending on the actual survey, age and structure. Never classify an applicant's field as species-rich grassland only because it lies in Herefordshire.
Barons Cross and edge-of-town redevelopment
Barons Cross Camp housing development illustrates a phased larger scheme on the town edge. Its permitted landscaping and onsite ecological evidence need to be assessed for each consent and condition; the project name alone is not a reusable statutory BNG baseline for adjacent parcels.
Separate protected-site and species requirements
Herefordshire Council requires phosphate nutrient neutrality for relevant developments in the mapped River Lugg catchment, which includes areas around Leominster. The River Lugg forms part of the River Wye SAC and is in an unfavourable condition; HRA must consider actual wastewater/drainage and development-specific impacts independently of the BNG metric.
The Council's Luston Integrated Constructed Wetland produces phosphate credits for eligible River Lugg development. Phosphate credits are not statutory biodiversity units, so applicants may need both a nutrient budget/mitigation and a separate eligible 10% BNG calculation. Confirm eligibility and obtain current quotations for the mitigation and habitat delivery required by the actual development.
Local context
What local development and regeneration examples show
Barons Cross Camp, Leominster is a documented council housing development: reserved matters application 193754 was granted permission in June 2024 for 353 dwellings, including 88 affordable homes, with planned six phases November 2025–July 2030.
The council timetable describes planned delivery across several phases. Actual development plots need their own operative permission, habitat and long-term management evidence.
Local project guidance
Does Leominster need one environmental payment or two different assessments?
The council's Luston wetland began operation in July 2023 and is designed to remove phosphorus from treated wastewater. Council monitoring records an average 68% total phosphorus concentration reduction over the 2023–24 independent monitoring period. The result measures phosphorus treatment; biodiversity units use a separate habitat calculation.
Where a Leominster development falls within the Lugg nutrient-neutrality catchment, it may require a separate budget and permitted mitigation. Under statutory BNG, qualifying development also needs habitat gains assessed with the appropriate metric.
Buyers should confirm entitlement, current available phosphate mitigation credits, terms and required HRA before spending; these credits cannot automatically be substituted for any legally registered biodiversity units.
Local project guidance
Which local green spaces matter to town developments?
The made 2019 Leominster Area Neighbourhood Plan includes LANP10 Green Infrastructure, LANP11 Open Spaces and LANP12 Greening the Town. Those are adopted local development-plan policies, not merely general amenity suggestions.
For development near protected open space, parks or settlement edges, the applicant must check the actual neighbourhood policies map, assess retained vegetation and connections, and design gains that respond to site access and management realities.
The town's strategic housing growth/Barons Cross permission should not be treated as approval to damage another mapped green space or watercourse simply because both are within Leominster.
Planning evidence
Ecological evidence for a planning application
Build the application around a consistent habitat baseline, layout and survey scope.
Local evidence and survey scope
Herefordshire Council's current BNG guidance requires an exemption statement with supporting measurements/photos where applicable, or the completed metric, detailed existing habitat plan and supporting BNG report for non-exempt cases. For relevant projects in the Lugg catchment it also requires a separate nutrient budget.
The final Biodiversity Gain Plan for an in-scope permission is ordinarily approved after planning permission but before commencement. Leominster's made neighbourhood plan, river SAC obligations and protected species can require other evidence independent of the metric; Herefordshire's private garden BNG policy is case-specific, especially for major schemes.
National application information
- Whether statutory BNG applies, with reasons for any exemption.
- The pre-development biodiversity value and completed statutory metric, with its version.
- Any relevant earlier baseline or explanation of habitat degradation.
- Details of irreplaceable habitat, where present.
- A scaled plan showing onsite habitats and the north direction.
See our habitat survey guide and BNG assessment service.
National requirements
Does statutory 10% BNG apply to this development?
Qualifying development in England normally needs at least 10% statutory Biodiversity Net Gain. For new applications from 6 August 2026, a whole red-line site of 0.2 hectares or less can be exempt if onsite priority habitat is not adversely affected. Wholly temporary development permitted for five years or less can also qualify, subject to the habitat condition. The dedicated self-build/custom-build exemption no longer applies to new applications from that date.
Application date, earlier permissions, section 73 history, development type and other exemptions affect the result. Assess the whole development site. Under the September 2026 NPPF, higher compulsory local BNG rates must relate to specific, justified and deliverable allocations; a general ambition for 20% does not establish a blanket requirement.
Metric and delivery
The metric and a deliverable habitat gain
Choose the right metric
The current government statutory biodiversity metric workbook is version 1.1.1, updated 10 November 2026. GOV.UK permits published statutory metric versions where appropriate. Record the version used with the baseline and calculation. The earlier non-statutory Metric 4.0 is not the statutory submission tool. The Small Sites Metric is available only for eligible schemes.
Support strategic significance
The Herefordshire LNRS was published 21 August 2026. For a Leominster site, the metric's strategic significance should be justified through a matching published riparian/hedgerow/grassland measure and real parcel-level habitat intervention, not by assuming its proximity to the Lugg automatically creates a High score.
Plan habitat delivery
The town's expansion and edge-of-town schemes may deliver some habitat onsite, such as retained hedgerow networks, riparian buffers and suitable grassland. They must test existing ecological constraints, the current statutory gain hierarchy, and registered offsite options for any lawful shortfall.
Luston phosphate mitigation credits cannot be entered as registered offsite biodiversity habitat units. Legal registration, habitat type, allocation and spatial risk require separate verification.
Secure long-term management
For major development, the gain hierarchy normally prioritises suitable onsite creation or enhancement. For eligible non-major new applications from 6 August 2026, onsite and registered offsite gains can sit at the same hierarchy level. Statutory credits remain the last option. Significant onsite gains and registered offsite gains need legally secured management for at least 30 years.
Plan the habitat management and monitoring and Biodiversity Gain Plan together. Check registered offsite unit requirements where a shortfall remains.
Project planning
Costs and programme for a Leominster project
Separate the required work
Budget appropriate UKHab/condition and species surveys, and for relevant mapped Lugg development add a separate nutrient budget/HRA, possible phosphate mitigation, and watercourse/floodplain evidence.
Budget phosphate mitigation separately from biodiversity units, where both are required. Survey, BGP/HMMP, registered offsite units and legal monitoring are distinct categories.
Plan the assessment in stages
Confirm the site boundary, development type and relevant Lugg catchment position at the start. Coordinate habitat surveys with nutrient and river evidence where required. Then agree the delivery route, legal responsibilities and ongoing management budget.
Your site checklist
Seven checks before submitting a Leominster BNG assessment
Record the evidence for the full site before commissioning surveys or submitting the application.
| Check | What to collect | Decision supported |
|---|---|---|
| 1. Confirm the decision-maker | Leominster's town, Brierley, Ivington and Wharton areas have distinct neighbourhood-plan designations and site characteristics. Confirm the full red-line boundary, adopted neighbourhood policies, Lugg nutrient catchment, and protected watercourse zones rather than assuming every HR6 postcode has identical land designation. | 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 | Herefordshire LNRS approved 14 August and final published 21 August 2026 — 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 | River Lugg SAC/Wye catchment phosphate neutrality, riverbank/floodplain, Lugg/Kenwater ecology, historic buildings and bats, hedgerows and traditional orchards, made neighbourhood green spaces. | 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. |

Leominster Biodiversity Net Gain FAQs
Answers to common planning, survey and habitat-delivery questions for projects in Leominster.
Who decides planning applications in Leominster?
Herefordshire Council is the unitary planning authority. Leominster Town Council's made neighbourhood plan is relevant but the town council does not issue most planning permissions.
Which biodiversity policies apply in Leominster?
The Herefordshire Core Strategy 2015 includes LD2 biodiversity and LD3 green infrastructure. The made Leominster Neighbourhood Plan adds LANP10 green infrastructure, LANP11 open spaces and LANP12 greening the town where mapped.
When was Leominster's Neighbourhood Plan adopted?
It was made on 22 March 2019 and now forms part of the statutory Herefordshire Development Plan for land in the designated neighbourhood area.
Is a new Herefordshire Local Plan already adopted?
No. The 2024 Regulation 18 draft was discontinued and a new 2025–2045 plan is preparing under the new system. The adopted 2015 Core Strategy and 2019 neighbourhood plan remain operative.
What LNRS covers Leominster?
Herefordshire Council published its LNRS on 21 August 2026, including 37 priorities, 100 measures and a mapped nature recovery strategy. Proposed habitat must match a suitable measure before strategic significance is claimed.
Does every Leominster development require phosphate credits?
No. Nutrient neutrality applies to qualifying development in the mapped River Lugg catchment where water-quality/Habitats Regulations effects arise. Eligibility and mitigation depend on the site and proposal.
Can Luston phosphate credits also meet statutory 10% BNG?
No. Luston supplies nutrient-mitigation phosphate credits for eligible developments, not necessarily registered biodiversity habitat units. Statutory BNG uses a separate metric and gain-site allocation rules.
What is the Barons Cross Camp housing development?
Herefordshire Council reports a June 2024 permission for 353 dwellings including 88 affordable homes, with phases planned into 2030. Check the specific phase, its ecological conditions and long-term management requirements.
Can a Leominster field be assumed to be species-rich grassland?
No. Hedgerows, orchards, farmland and grassland vary parcel by parcel. A proper UKHab baseline and condition survey is needed to classify a development site.
Are eligible sites below 0.2 hectares exempt from BNG?
New qualifying applications from 6 August 2026 can be exempt when the whole development site is 0.2 hectares or less and onsite priority habitat is not adversely affected. Other transitions apply.
Can a Leominster project buy offsite biodiversity units?
Yes if suitable units are legally registered and allocated under habitat trading/spatial risk rules. Confirm the actual unit type, availability and allocation in the government gain-site register.
What information should I send ACP for a Leominster quotation?
Send the site postcode, red-line plan, development drawings, available ecology reports and planning timetable. Highlight nearby Lugg/Kenwater watercourses, hedgerows, nutrient catchment and any existing permission.
