Bedfordshire BNG / County planning guidance

Biodiversity Net Gain in Bedfordshire

Biodiversity net gain in Bedfordshire starts with the correct council, habitat evidence and site design. Bedford Borough, Central Bedfordshire and Luton use separate local plans. This guide brings their requirements together with the published nature recovery strategy.

ACP helps developers, architects, planners and landowners scope ecological surveys, calculate biodiversity units and prepare planning evidence. Our BNG assessment service explains the habitat baseline and reporting work available for your proposal.

Bedford Borough / Central Bedfordshire / Luton

Which Bedfordshire planning authority deals with your site?

Bedfordshire does not have a county council responsible for every planning application. Instead, Bedford Borough Council, Central Bedfordshire Council and Luton Borough Council make ordinary planning decisions within their own boundaries.

The name of your nearest town is not always enough. For example, development around Luton's edge can sit within Central Bedfordshire. First, confirm the red-line site boundary using the appropriate planning authority map.

Our BNG assessment service can establish the habitat baseline and reporting scope for your site.

A practical route finder / four evidence checks

Which Bedfordshire BNG planning route should you check?

Work through these four checks to prepare a site brief for your ecologist or planning team.

1. Which of Bedfordshire's three planning authorities covers the site?

Confirm the whole red-line boundary. Bedfordshire no longer has a county council deciding ordinary planning applications.

  • Bedford Borough: adopted Local Plan 2030 and biodiversity Policies 42S and 43. The former proposed 2040 plan was withdrawn.
  • Central Bedfordshire: adopted Local Plan 2015–2035, Policies EE1 and EE2.
  • Luton: adopted Local Plan 2011–2031, Policy LLP28 and related landscape/green-space policies.

Do not choose the authority from a neighbouring town or postcode alone; use the actual boundary and planning portal.

2. Is this an ordinary application or a minerals/waste proposal?

Ordinary schemes use the correct unitary council's adopted Local Plan and current local validation list.

Relevant minerals and waste proposals follow the three-council adopted 2014 Minerals and Waste Local Plan and appropriate processing arrangements. The replacement plan's October–November 2026 scoping consultation is not an adopted plan.

Check the official joint minerals/waste plan status.

3. Is mandatory statutory BNG relevant to this application?

Check the planning application date, proposal type, total red-line area, existing priority habitats and applicable transitionals. From 6 August 2026 some qualifying developments on sites no larger than 0.2 hectares can be exempt if the works do not impact on-site priority habitat.

Check other exemptions separately. In particular, new self-build and custom-build applications no longer qualify for a blanket exemption simply because of their building method. Local biodiversity policies, protected species and site-designation rules may still apply.

Check current government exemption guidance.

4. What evidence will support this project's BNG proposal?

Read the actual council's current validation list. Assemble proportionate habitat and condition surveys, baseline and proposed habitat plans, the appropriate statutory metric and its version, relevant watercourse assessment, and BNG delivery information.

Use the published Bedfordshire Local Nature Recovery Strategy and its Local Habitat Map to review potential nature recovery measures. A map location does not automatically confirm strategic significance, available off-site units or a suitable land-management proposal.

For permissions subject to the biodiversity gain condition, an appropriate Biodiversity Gain Plan must be approved before commencement. Significant on-site and registered off-site gains normally need suitable legal securing and management for at least 30 years.

Adopted plans / current validation / emerging proposals

What biodiversity policies apply in Bedford, Central Bedfordshire and Luton?

All three authorities apply the statutory national BNG framework. However, their adopted Local Plans and validation lists are different.

Bedfordshire councils: adopted policies and application evidence
CouncilAdopted biodiversity planning policyWhat to check before applying
Bedford BoroughLocal Plan 2030, adopted 15 January 2020. Policy 42S protects biodiversity and geodiversity; Policy 43 addresses biodiversity enhancement.Revised local validation checklist from 29 September 2026, suitable habitat survey, baseline/proposed plans, metric and delivery information.
Central BedfordshireLocal Plan 2015–2035, adopted 22 July 2021. EE2 Enhancing Biodiversity and EE1 Green Infrastructure.Dedicated Planning Applications and BNG guidance: habitat baseline and proposed habitat plans, editable metric and supporting evidence.
LutonLocal Plan 2011–2031, adopted 7 November 2017. LLP28 Biodiversity and Nature Conservation, plus LLP27 open space.Council's BNG planning-application requirements: pre-development values, metric/version, earlier dates, degradation and irreplaceable habitat evidence, plus scaled plans.

The table is an initial comparison. Always read the actual plan and latest validation checklist for your proposal. You may also need relevant neighbourhood plan, protected-site, tree or landscape policies.

Do emerging plans change the position?

Not automatically. Bedford's Local Plan 2040 was withdrawn in October 2025. The adopted Local Plan 2030 remains the key starting point while the replacement Local Plan 2050 is prepared. Its priorities consultation closes on 23 November 2026.

Central Bedfordshire adopted its existing Local Plan in 2021. Its new Local Plan 2050 has completed initial preparation stages, with further consultation programmed from 30 November 2026.

Meanwhile, Luton's adopted 2017 Local Plan remains operative. Its successor formally entered the new plan-making process in 22 October 2026.

An emerging plan can sometimes carry planning weight, depending on its stage and contents. However, a consultation timetable is not an adoption notice. Confirm the latest position when your application is assessed.

Minerals and waste applications

The three councils share the adopted January 2014 Minerals and Waste Local Plan: Strategic Sites and Policies. Relevant schemes need the correct authority and shared application-processing route.

The replacement plan is at scoping consultation, running from 12 October to 27 November 2026. Its proposals are not adopted policy.

Check the joint minerals and waste consultation.

Habitat baseline / exemptions / statutory metric

How does statutory biodiversity net gain work in Bedfordshire?

BNG compares the biodiversity value of a site before and after development. The statutory biodiversity metric uses the habitats present and their condition, area or length, distinctiveness and other prescribed factors.

First, establish the baseline. Next, assess how the design retains, enhances or creates habitats. The calculation can then show the expected change in biodiversity units and whether a shortfall remains.

A well-prepared assessment should help shape the layout early. For instance, retaining an existing hedgerow can be more realistic than replacing it with new planting and relying on future establishment.

Where the statutory condition applies, the Biodiversity Gain Plan must be approved before development starts. Other supporting information may be required with the planning application itself.

Do all smaller developments need 10% BNG?

No. Statutory exemptions and transitional rules apply.

For qualifying applications made on or after 6 August 2026, developments on a red-line site of 0.2 hectares or less may be exempt if the proposal does not impact on-site priority habitat.

Householder applications have a separate exemption. There are also specific de minimis and temporary-development rules. However, new self-build and custom-build applications no longer have their former general exemption from 6 August 2026.

Use the current national legislation and GOV.UK guidance alongside any separate council biodiversity or ecology requirements.

An exemption from the statutory 10% condition does not remove protected-species duties, local habitat protections or other relevant planning evidence.

Which biodiversity metric should a project use?

Where mandatory BNG applies, the official Statutory Biodiversity Metric or Small Sites Metric, if eligible, provides the required calculation method.

The full Statutory Biodiversity Metric was updated to version 1.1.0 on 3 November 2026. GOV.UK allows qualifying earlier versions of the *statutory* tool, but a pre-statutory Metric 4.0 workbook is not a current statutory calculation.

The correct tool depends on your development and its ecology. In particular, eligibility for the Small Sites Metric is not the same as being exempt from mandatory BNG.

The metric separately assesses area habitats, hedgerows and watercourses. These unit categories cannot simply be added together or used to substitute for one another. Watercourses may also require additional condition assessment and catchment information.

See our Statutory Biodiversity Metric service or Small Sites Metric guidance to understand the appropriate route.

Published strategy / Local Habitat Map / habitat opportunities

Bedfordshire Local Nature Recovery Strategy and habitat map

The Bedfordshire Local Nature Recovery Strategy (LNRS) is published and adopted. It was developed under the leadership of Central Bedfordshire Council, with Bedford Borough, Luton and environmental partners.

The strategy identifies priorities and locations for restoring nature across Bedfordshire. It includes a statement of biodiversity priorities and a Local Habitat Map, as required for England's local nature recovery strategies.

The work was approved in late 2025 and listed by GOV.UK as published in January 2026.

The LNRS can help landowners, designers and ecologists consider opportunities that connect habitats. However, the mapped areas do not automatically approve a habitat proposal or guarantee extra biodiversity units.

How should the Bedfordshire habitat map be used?

  1. Locate the actual site. Confirm the red-line boundary and choose the published Bedfordshire LNRS map rather than a neighbouring county's strategy.
  2. Check the mapped information. Review existing areas important for biodiversity and any relevant mapped potential nature recovery measures.
  3. Compare the site evidence. Check whether the proposed habitat fits the actual survey findings, soils, water conditions and access.
  4. Record the reason for the metric assessment. Where strategic significance is claimed, identify the relevant published measure and explain the habitat match.
  5. Check practical delivery. A mapped opportunity still needs landowner agreement, a feasible habitat design and suitable long-term management.

The map is not a register of available biodiversity units. Equally, it does not replace UKHab survey work, protected-site assessment or the legal process for securing gains.

Chalk slopes / Greensand Ridge / river corridors / urban habitats

Habitats and ecological constraints across Bedfordshire

Bedfordshire includes several contrasting landscapes. Therefore, the most useful habitat proposals are those designed for the actual site, not chosen from a generic planting menu.

Chilterns chalk slopes and grasslands

The southern county includes parts of the Chilterns National Landscape, with chalk slopes, grassland and woodland. Retaining existing habitats may be important, while new grassland depends on appropriate soils and management.

Where relevant, protected landscape and nature conservation policies apply alongside the metric. Check actual boundaries rather than assuming a nearby village is within the designation.

Greensand Ridge woodland and heathland

The Greensand Ridge has woodland, acidic soils and heathland habitats. These can offer valuable ecological connections, but each restoration proposal needs suitable conditions.

Ancient woodland, mature trees and higher-value habitats must be assessed carefully. The intention to create a habitat elsewhere does not automatically justify losing an important existing one.

Great Ouse, Ivel, Ouzel, Flit and Lea river networks

River corridors and floodplains present habitat opportunities and important constraints. They can also affect drainage, water quality, flooding and the design of ecological corridors.

Where a project affects a watercourse, the watercourse unit module and river condition evidence may be relevant. Separate Environment Agency, drainage or other consents may still be necessary.

Marston Vale, farmland and urban sites

The Forest of Marston Vale, rural hedgerow networks and former mineral-working areas offer different habitat-restoration settings. However, existing minerals restoration obligations and statutory BNG must not be confused.

In Bedford, Kempston and Luton, older trees, green spaces, sustainable drainage and some brownfield habitats can be relevant. A small urban site may still contain important ecology.

Designated sites, protected species and ancient woodland require separate screening. For example, Chilterns Beechwoods SAC includes land in Bedfordshire. Its relevance depends on the site location and likely impacts of the proposal.

Gain hierarchy / registration / 30-year management

On-site improvements, off-site units and long-term management

The first step is to understand which habitats can be retained. A suitable design can then consider realistic improvements within the development boundary, including habitat creation or enhancement where conditions allow.

Where the statutory metric identifies a shortfall, a project may need eligible registered off-site biodiversity units. These are not the same as statutory biodiversity credits, which remain a last-resort mechanism. The unit category, trading rules, spatial factors, registration and allocation to the permission all require checking.

For qualifying non-major applications made from 6 August 2026, on-site creation or enhancement and registered off-site gains have equal priority under the revised national gain hierarchy. Other application types and earlier permissions may follow a different hierarchy. Avoidance of important habitats and compliance with other ecology obligations still matter.

Can a Bedfordshire landowner provide biodiversity units?

Potentially, but available land alone is not enough. A proposed gain site needs a credible baseline, habitat design, long-term management programme and the correct legal securing and registration.

The Bedfordshire LNRS can help identify appropriate landscape-scale opportunities. However, a mapped measure does not itself establish planning permission, habitat feasibility, registration or demand for the units.

Significant on-site and registered off-site habitat gains normally require at least 30 years of management and monitoring. The legal agreement and Habitat Management and Monitoring Plan should make the delivery duties realistic.

For more detail, see our off-site biodiversity units guidance and habitat management and monitoring plan advice.

Ten checks before submission

A practical Bedfordshire BNG submission checklist

Use this checklist to organise the evidence for your planning submission.

  • Confirm the boundary and council. Provide the accurate red-line plan and identify Bedford Borough, Central Bedfordshire or Luton.
  • Check the planning route. Record the application type and date, and whether it falls under ordinary planning or minerals/waste arrangements.
  • Assess exemptions. Check the current national statutory criteria, priority-habitat impacts and any relevant transitional provisions.
  • Review local evidence rules. Check the applicable adopted Local Plan, current validation list, ecology requirements and relevant guidance.
  • Establish the baseline. Arrange proportionate habitat mapping and condition surveys, including hedgerows and watercourses as appropriate.
  • Check other constraints. Consider protected sites and species, trees, water and flood issues, landscape policy and existing legal obligations.
  • Use the LNRS appropriately. Review mapped potential measures, note the source date and assess the genuine ecological fit.
  • Reconcile the proposed design. Check baseline and proposed habitat plans against the correct metric and its version.
  • Plan delivery. Identify the required Biodiversity Gain Plan, management and monitoring arrangements, legal security and registered off-site allocation if needed.
  • Check documents agree. Use the same site areas, habitat parcel labels and design revision in the plans, calculations and reports.

A complete submission explains how the proposed gain can be delivered. A percentage in a spreadsheet does not by itself demonstrate that habitat creation or long-term management is realistic.

Scope the work / assess habitats / prepare delivery evidence

How ACP can support biodiversity net gain projects in Bedfordshire

1. Clarify requirements and survey scope

We review the location, development proposal, planning stage and information already available. This helps identify the likely ecological surveys, evidence gaps and BNG reporting requirements.

2. Assess habitats and test the design

Where instructed, the assessment can include habitat baseline mapping, condition surveys and the applicable statutory metric. We can then work with the design team to consider how retention, planting and other habitat proposals affect the calculation.

3. Prepare evidence for delivery

Depending on the agreed scope, we can help prepare the BNG report, Biodiversity Gain Plan information, or habitat management and monitoring advice. Any off-site arrangement, legal securing or third-party work must be confirmed as part of the project.

Send your red-line plan, a description of the works and any planning correspondence. We can recommend a proportionate next step. For coordinated submission evidence, see our BNG report for planning and Biodiversity Gain Plan guidance.

Local planning questions / practical answers

Bedfordshire biodiversity net gain FAQs

Which councils deal with planning applications in Bedfordshire?

The three unitary planning authorities are Bedford Borough Council, Central Bedfordshire Council and Luton Borough Council. Each has its own adopted policies and validation requirements. Relevant minerals and waste proposals use a separate joint policy framework.

Is there a Bedfordshire County Council that approves BNG applications?

No. Bedfordshire County Council ceased operating in 2009. For ordinary development, use the unitary council covering your actual red-line site. Central Bedfordshire leads the countywide Local Nature Recovery Strategy but does not decide all three councils' planning applications.

Has Bedfordshire's Local Nature Recovery Strategy been published?

Yes. The strategy was approved in December 2025 and subsequently published. GOV.UK recorded it as published by January 2026. It covers Bedford Borough, Central Bedfordshire and Luton, with a Local Habitat Map and priorities for nature recovery.

Does an LNRS map location guarantee biodiversity units?

No. The map identifies important habitat areas and potential nature recovery measures. Any proposed habitat must match the strategy and site ecology before the metric's strategic significance can be justified. The map is not an off-site gain register or an automatic metric uplift.

Is Bedford's Local Plan 2040 now adopted?

No. The proposed Bedford Local Plan 2040 was withdrawn in October 2025. The adopted Local Plan 2030 remains the main current framework, while the council prepares a new Local Plan 2050. Check the latest plan status before applying.

Which policy is relevant in Central Bedfordshire?

The Central Bedfordshire Local Plan 2015–2035 was adopted in July 2021. EE2 Enhancing Biodiversity and EE1 Green Infrastructure are important starting points, alongside the council's current application-stage BNG guidance.

Does Luton have separate biodiversity policies?

Yes. The adopted Luton Local Plan includes LLP28 Biodiversity and Nature Conservation and other relevant green infrastructure, landscape and open-space policies. Luton also has its own BNG validation information and is preparing a successor Local Plan.

Does every small Bedfordshire development need 10% BNG?

No. Exemptions and transitional rules apply. For qualifying applications made from 6 August 2026, a red-line site of 0.2 hectares or less may be exempt where no on-site priority habitat is impacted. Check the proposal type, date and any separate local biodiversity requirements.

Are new self-build homes exempt from biodiversity net gain?

Not simply because they are self-build. The former general self-build and custom-build exemption was removed for new applications made from 6 August 2026. Earlier applications can raise transitional questions. Check the current national guidance for the application date.

Can I use the Small Sites Metric for a minor development?

Only if the scheme meets the tool's eligibility requirements. A minor planning application is not automatically suitable for the simplified metric, and eligibility is different from statutory exemption. More complex habitats or watercourse impacts may require the full statutory metric.

Is the replacement Bedfordshire minerals and waste plan in force?

No. The replacement plan was at scoping consultation in October and November 2026. The adopted 2014 joint Minerals and Waste Local Plan remains relevant until lawfully replaced. Confirm the responsible authority and local application requirements for the specific scheme.

When does a Biodiversity Gain Plan need approval?

For a permission subject to the statutory biodiversity gain condition, the plan normally needs approval before development begins. Supporting biodiversity statements, surveys and metric evidence may still be needed earlier for planning validation. Phased or nationally significant schemes have distinct procedural requirements.
