Liverpool BNG advice

Biodiversity Net Gain in Liverpool

Plan your Liverpool 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 Liverpool site.

Local planning

Liverpool city, Merseyside and the wider city region

Identify the council for the actual land

Liverpool City Council is the ordinary planning authority for the city. Sefton, Knowsley, St Helens, Wirral and Halton determine applications within their own areas. A Liverpool postal address or city-region description does not establish the planning boundary.

Confirm the red-line site, access works, drainage land and relevant allocations. Check applicable neighbourhood-plan requirements and the adopted policies map before deciding the evidence route.

Use the right level of geographic guidance

Our Merseyside BNG guide covers the wider county context. The North West hub provides regional navigation. This page focuses on Liverpool City Council’s policies, submission requirements and delivery issues.

The Liverpool City Region nature recovery strategy covers six authorities, including Halton. That strategic area is wider than the five metropolitan boroughs of Merseyside. Keep those boundaries separate when describing a site or selecting offsite units.

Local planning

Adopted Liverpool policies for an ecological design response

The Liverpool Local Plan 2013–2033 was adopted on 26 January 2022. Read its written policies and maps alongside the site allocation and relevant supplementary guidance. The following references are from the adopted plan, rather than the replacement plan’s different numbering.

Adopted policies to check against the development site
PolicySubjectPractical response
GI5 — Water SpacesThe Mersey, docks, canal and other water spacesCoordinate the waterside layout with nature conservation, water quality, access and setting. Investigate effects on supporting habitat for protected birds.
GI6 — Protection of Biodiversity and GeodiversityDesignated sites, habitats, species and ecological effectsProvide an ecological appraisal where required. Address avoidance, mitigation and compensation, including effects beyond Liverpool’s boundary.
GI7 — Nature Improvement AreaThe functioning and habitat opportunities of the Nature Improvement AreaCheck the relevant focus-area evidence and explain how the proposal supports connections and appropriate habitat enhancement.
GI8 — New Planting and DesignAppropriate, sustainable planting and landscape designSpecify suitable species, space, establishment and management. Design planting around the actual growing conditions.
GI9 — Management of Existing Site VegetationExisting trees and vegetation in the design processProvide the relevant tree evidence and show retained features, constraints and protection alongside the habitat assessment.

The adopted policy text contains the operative wording and qualifications. These policies address wider ecological and design matters. A statutory BNG percentage does not replace their assessment.

Planning changes

The Local Plan 2043 is a replacement proposal

A recent consultation does not make a policy adopted

The Regulation 19 consultation ran from 10 August to 30 September 2026. The council describes this as the publication stage before independent examination. The proposed plan would replace the current policies following adoption.

Check the current plan-making page for subsequent stages. Do not cite proposed GI8 biodiversity net gain wording as though it were the adopted GI8: the adopted policy concerns planting and design.

Use local design guidance at the relevant location

The council’s supplementary guidance collection includes the Waterfront SPD and documents for regeneration areas. The Pumpfields and Limekilns SPD was adopted on 2 June 2026; the collection also covers Paddington Village and the North Docks context.

Identify the document that applies to the plot. Read its design and public-realm expectations with ecology, drainage and access requirements, rather than treating regeneration status as an ecological exemption.

Nature recovery

Use the published Liverpool City Region nature recovery strategy

The Combined Authority approved its first LNRS on 6 March 2026 and launched it on 20 March. The strategy sets regional recovery priorities across habitats including wetlands, grassland, woodland and urban areas. Use the strategy portal and Local Habitat Map together.

Distinguish existing nature sites from opportunities

The map separates core local nature sites from opportunity areas. Opportunities have a primary measure and, in many cases, a secondary measure. These identify potential habitat actions; they do not grant permission or establish a delivery agreement.

Check the actual location and relevant measure, then verify conditions on the ground. An unmapped site may still offer useful ecological improvements.

Explain strategic significance in the metric

Record which published measure supports the proposed habitat action. Assess whether the intervention matches that measure and is feasible within the site’s drainage, soil, access and management constraints.

Apply the current statutory metric instructions and explain the chosen score. Being within the city region does not automatically justify a higher value. The map also cannot replace a habitat survey or prove that a unit supplier has available stock.

Local ecology

Local habitat connections that can affect a Liverpool proposal

Ecological context: investigate the features relevant to the actual site
Location or networkWhat to consider
Mersey waterfront and docklandAssess waterside habitat, birds, lighting, construction disturbance, water quality and changes to access. Consider the setting and linked habitats as well as the red-line land.
River Alt and M57 corridorThe adopted plan identifies this as a Nature Improvement Area focus area partly within the city. Check local watercourses, habitat links and the effect of infrastructure on connectivity.
Netherley Brook and Ditton Brook corridorAssess water-related features, connecting vegetation and potential habitat restoration where relevant to the parcel. Coordinate drainage and future maintenance access.
Mersey Estuary focus areaScreen credible pathways to protected sites and the land used by their qualifying wildlife. BNG and Habitats Regulations evidence answer different questions.
City centre, Knowledge Quarter and urban neighbourhoodsSmall green spaces, trees, buildings and unmanaged plots can contribute to a wider network. Test green-roof, planting and drainage opportunities against realistic growing conditions.

The adopted plan identifies the Alt/M57, Netherley/Ditton Brook and Mersey Estuary focus areas. That landscape context does not establish the presence of a priority habitat or species on every nearby site. Use records and field evidence before assigning habitat types or conditions.

Planning evidence

Liverpool’s application-stage BNG evidence checklist

The council’s BNG submission guidance sets additional local requirements alongside the national information requirements. Its checklist is particularly useful for keeping the habitat maps and spreadsheet consistent. For a qualifying application, assemble the documents together.

The six items identified in Liverpool’s published submission guidance
DocumentWhat it needs to demonstrate
Biodiversity checklistIdentify applicability, habitats, ecological information and survey needs.
Draft biodiversity gain planExplain the baseline, habitat response, calculated gain, use of the statutory metric and delivery hierarchy.
Full metric spreadsheetSubmit the Excel calculation with macros disabled. The council says summary outputs alone are not accepted.
Baseline habitat planShow existing compartments with the habitat references used in the baseline calculation.
Post-intervention habitat planIdentify retained, enhanced and created habitats with references matching the relevant metric tabs.
Condition assessmentsSupply evidence for each applicable habitat parcel rather than an unsupported condition label.

The draft gain plan requested at application stage is not the approved post-permission Biodiversity Gain Plan. Keep the version, drawings and calculation date clear. Our planning evidence guidance helps organise the supporting documents.

Current national framework

Read older local guidance with the current national rules

The council webpage retains some earlier wording

Liverpool’s page still lists small-scale self-build and custom-build development among exemptions and describes an onsite-first delivery route. Those statements need to be read with the national changes effective from 6 August 2026 and their transition provisions.

For a new application, establish the actual exemption criteria and relevant submission date. Do not rely solely on an older council summary or assume a small development is exempt without checking every condition.

Explain the applicable hierarchy in the report

For non-major applications made on or after 6 August 2026, the national framework places onsite enhancement, onsite creation and registered offsite gains at the same preference level. Statutory credits remain the last option.

Earlier applications, major development and section 73 cases need the appropriate separate treatment. Record that reasoning so the council can assess the proposal against the correct version of the rules.

National requirements

Does statutory BNG apply to your development?

Qualifying planning permissions in England normally require at least 10% biodiversity gain. Start with the development type, application date, whole red-line area and habitats affected. Record the reasons and evidence if claiming an exemption.

Rules from 6 August 2026

New applications on sites of 0.2 hectares or less may be exempt, provided 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 and custom-build exemption no longer applies to new applications from that date.

Earlier applications and other exemptions

Householder development has a separate exemption. The de minimis route has specific habitat-impact thresholds. Earlier permissions and section 73 variations need their own transitional assessment. Avoid assuming that “one house” or “small site” settles the question.

Use the BNG exemption guide with the current government exemptions.

Survey and design

Choose the metric and test the layout early

Use a statutory tool and record its version

Defra’s statutory biodiversity metric workbook was updated to version 1.1.1 on 10 November 2026. Record the version used and follow the accompanying rules. Published statutory versions can remain acceptable; non-statutory Metric 4.0 is a different tool.

The Small Sites Metric has separate eligibility restrictions. Confirm suitability before selecting it. See the statutory metric guide and current government tools.

Make the figures deliverable

Classify and assess existing habitats before clearance. Calculate area, hedgerow and watercourse units separately, then apply the relevant trading rules. State the evidence for condition and strategic significance instead of assuming the most favourable scores.

Test changes to access, drainage and landscaping with the ecologist. Habitat area, target condition, establishment time and maintenance access must remain credible after engineering changes. Update the plans and metric together.

Separate ecological duties

Mersey habitats and protected species need separate assessment

A metric surplus does not discharge an HRA

Where there is a credible pathway to the Mersey Estuary, Liverpool Bay or another internationally protected site, the authority must consider the relevant Habitats Regulations process. Effects can arise through disturbance, water quality or changes to use and access.

The council publishes recreational-management guidance alongside its Local Plan documents. Check the current approach for the proposal. Do not assume a standard contribution applies to every site or that buying BNG units resolves a protected-site effect.

Scope urban species work from the site features

Buildings, trees, water features and vegetation may trigger specialist surveys. Establish those needs before demolition, clearance or a fixed construction programme. A preliminary assessment may identify further seasonal work.

Use the current appropriate-assessment guidance where relevant. Keep designated-site, species and tree requirements distinct from the habitat-unit calculation, including where statutory BNG is exempt.

Off-site delivery

Habitat banks and off-site units for Liverpool development

Council proposals are not confirmed stock

Liverpool’s BNG page says it is considering four sites for potential gain-site development. It does not identify those proposals as a current stock list with named registered parcels, unit quantities and sale prices.

Treat that information as a developing council initiative. For a live project, request written details of any available scheme and verify the registration and allocation route before relying on it.

A published wider-area example: Ellesmere Port

Environment Bank publishes Ellesmere Port Habitat Bank, reference BGS-260226001, between Bridge Trafford and Mickle Trafford. It is in Cheshire West and Chester’s planning area and the Mersey Valley National Character Area.

The provider lists meadow, wetland, ponds, orchard, scrub and woodland options, subject to availability. This is a wider-area example, not a Liverpool City Council gain site or a guarantee of a favourable location multiplier.

For any proposed purchase, check compatible habitat units, location rules, registration, legal security and allocation to the development. Obtain a dated quotation and inspect the official gain-site register. Registration does not prove that units remain unsold.

Costs and responsibilities

Liverpool’s published BNG monitoring fees

The council’s BNG monitoring fee document was checked on 11 November 2026. It states the following charges where significant onsite ecological enhancements are secured. Confirm the applicable current sum and the authority’s significance assessment for the actual proposal.

Published Liverpool BNG monitoring charges
Delivery categoryPublished chargeQualification
Onsite minor application£2,729Where significant enhancements are proposed within the planning application boundary.
Onsite major application£10,308Where significant enhancements are proposed within the planning application boundary.
Habitat bank or gain siteBespoke feeAssessed case by case for a section 106 agreement with the council.

What these figures represent

These are council monitoring charges. The document says they accompany a section 106 agreement and are additional to the stated 15% fee where other non-BNG planning obligations are secured for the same application.

Do not apply that 15% to a unit purchase by assumption. Ask the council to confirm the calculation basis, legal costs, payment trigger and any updated schedule.

Keep the remaining budget separate

Allow separately for ecological surveys, metric calculations, reporting, habitat establishment, maintenance and any offsite purchase. A unit quotation should state the habitat, quantity, reservation terms and included administration.

No verified live unit price is quoted here. Government statutory credits have separate national prices and last-resort rules. Monitoring fees do not pay for the creation and management of the habitat itself.

Local evidence

A published Liverpool estate biodiversity commitment

University of Liverpool: baseline, development and procurement

The University’s Biodiversity Plan success measures include an estate habitat baseline target for July 2026, at least 10% BNG linked to estate developments, and biodiversity in competitive capital-project tenders by January 2027.

These are published institutional commitments. They are not evidence that every target has been completed, that a particular gain plan is approved or that ACP worked on the estate.

The practical lesson for a development team

Link the survey baseline to procurement and future maintenance. A habitat target can be lost between planning drawings, contractor specifications and the operating budget if responsibility is unclear.

Specify the required habitat outcomes, establishment method, management access and reporting obligations. This helps the ecological design survive the move from planning permission to construction and occupation.

After permission

Turn the gain strategy into secured, manageable habitat

Agree the legal and land-management route

Identify significant onsite gains early and discuss how they will be secured. Map the parcels, ownership and maintenance boundaries. For offsite delivery, verify the legal agreement and allocation evidence before finalising the gain plan.

The habitat management and monitoring plan should set out measurable targets, management tasks, monitoring, reporting and corrective action. State who funds and performs each task.

Keep the final plans and calculation aligned

Update the metric when the design changes. Check that drainage, access, utilities and planting proposals occupy the same land shown in the habitat plans, without double counting or conflicting uses.

Qualifying development must not commence before the required Biodiversity Gain Plan approval. Programme that stage, any section 106 agreement and the supply of offsite evidence alongside the construction timetable.

Your next steps

A practical Liverpool planning evidence checklist

  1. Confirm the authority and policy version

    Locate the site within Liverpool City Council’s boundary. Check adopted policies, allocations, relevant guidance and the separate emerging-plan status.

  2. Establish applicability and survey needs

    Apply the current national rules and transition provisions. Scope habitat, species and designated-site evidence before clearance.

  3. Prepare the six-part council submission

    Assemble the checklist, draft gain plan, full spreadsheet, baseline and post-intervention plans, and applicable condition assessments.

  4. Match the recovery map to feasible habitat actions

    Record the LNRS measure and justify strategic significance. Test soils, drainage, establishment and management access.

  5. Secure the delivery and budget

    Agree significant onsite gains, monitoring fees and legal responsibilities. Verify registration, compatible units and allocation for an offsite purchase.

  6. Complete the pre-commencement and management stages

    Obtain required gain-plan approval and maintain consistent plans. Implement the habitat works, management, monitoring and remedial programme.

Common local questions

Liverpool Biodiversity Net Gain FAQs

Who determines ordinary planning applications in Liverpool?

Liverpool City Council determines applications within the city boundary. Sefton, Knowsley, St Helens, Wirral and Halton have their own planning authorities. Confirm the actual land boundary rather than a postal address.

Which Liverpool Local Plan is adopted?

The Liverpool Local Plan 2013–2033 was adopted on 26 January 2022. The replacement Local Plan 2043 underwent Regulation 19 consultation in August and September 2026. Check its subsequent status before using proposed policies.

Is adopted policy GI8 the biodiversity net gain policy?

No. Adopted GI8 concerns new planting and design. Proposed policies use different numbering. In the adopted plan, GI6 addresses biodiversity and geodiversity, alongside GI7, GI8 and GI9 on related ecological and landscape matters.

What BNG documents does Liverpool request?

The published guidance identifies a biodiversity checklist, draft gain plan, full metric spreadsheet, baseline habitat plan, post-intervention habitat plan and applicable condition assessments. Match habitat references across the plans and calculation.

Can I submit only the metric summary?

Liverpool’s published guidance asks for the full Excel metric with macros disabled and says summaries are not accepted. Check the current validation requirements and submit the supporting habitat plans and condition evidence.

Which nature recovery map covers Liverpool?

The published Liverpool City Region LNRS provides a Local Habitat Map with core nature sites and opportunity areas. Check the actual measure and site conditions before applying strategic-significance rules in the metric.

What are Liverpool’s published BNG monitoring fees?

The checked council schedule lists £2,729 for minor applications and £10,308 for major applications with significant onsite enhancements. Habitat-bank agreements attract bespoke fees. Confirm the applicable current sum and other legal or monitoring charges with the council.

Does Liverpool already have four council habitat banks selling units?

The council says it is considering four potential gain sites. That statement does not establish registered stock or available units. Request current named-site details, registration and allocation evidence before relying on a purchase.

Do older council exemption lists cover the August 2026 changes?

Not necessarily. The checked Liverpool webpage retains earlier self-build and hierarchy wording. Use current national guidance and the application-date transition rules to establish the correct exemption and delivery route.

What should I send ACP for a Liverpool BNG quotation?

Send the red-line plan, site address or grid reference, proposal, planning stage, existing ecology reports and council advice. Include available landscape, drainage and lighting plans so the remaining evidence can be scoped.
