ACP Consultants can help with habitat surveys, biodiversity metric calculations and a practical BNG delivery plan for your Lincoln site.
Local planning guidance
Who decides development applications in Lincoln?
City of Lincoln Council is the normal local planning authority for Lincoln. The jointly adopted Central Lincolnshire Local Plan also applies in West Lindsey and North Kesteven, but their district councils determine development outside the City. Lincolnshire County Council leads the shared Greater Lincolnshire LNRS and has county minerals/waste duties. Grimsby is in North East Lincolnshire Council and Yorkshire and the Humber, not within this Central Lincolnshire S61 planning jurisdiction.
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.
Which adopted biodiversity policies apply in Lincoln?
The Central Lincolnshire Local Plan was formally adopted 13 April 2023 by the joint committee representing Lincoln City, North Kesteven and West Lindsey. Its S60 Protecting Biodiversity and Geodiversity, S61 Biodiversity Opportunity and Net Gain, S63 Green Wedges and S66 Trees, Woodlands and Hedgerows establish the framework for ecological retention and enhancement. S61 requires 10% gain for qualifying development and outlines the Biodiversity Opportunity Mapping/strategic-significance framework; current national exemptions and 2026 NPPF affect how any requirements apply to exempt schemes.
| Adopted policy or document | What it covers | Practical implication for the application |
|---|---|---|
| S60 — Protecting Biodiversity and Geodiversity | Central Lincolnshire Local Plan adopted 13 April 2023 | Avoid impacts on local and nationally important habitats and species, and provide ecological assessment proportionate to actual risks. |
| S61 — Biodiversity Opportunity and Net Gain | Adopted Central Lincolnshire Plan 2023 | Apply statutory metric when eligible, relevant biodiversity opportunity mapping/LNRS measures and local Biodiversity Gain Statement. |
| S63 — Green Wedges | 2023 adopted Central Lincolnshire Plan | Check actual mapped green wedge land and character protection before selecting an urban-edge development design. |
| S66 — Trees, Woodland and Hedgerows | 2023 adopted Central Lincolnshire Plan | Consider retained tree canopy, root protection and hedgerow ecological significance alongside BNG units. |
The requirements above are separate from the later national statutory BNG condition. A project should not achieve numerical gains by damaging priority habitats, designated land or protected species. Existing trees, water bodies, wetlands, wildlife corridors and high-value grassland must be assessed under their own applicable protections.
Which proposed plans should applicants monitor?
Central Lincolnshire began a new Local Plan review and had opened a scoping consultation to 17 December 2026, alongside a renewed call for sites. This is an early emerging stage, not a replacement adopted development plan. Separately, proposed revisions to the Central Lincolnshire Local Validation Lists were consulted on in May–June 2026 but had not been adopted by 8 November. Existing adopted lists remain operative. The Central planning team published a specific October 2026 note about interaction between its 2023 plan and the newer national NPPF, rather than silently replacing the S61 plan.
A consultation or Gateway stage is not an adopted Local Plan. Therefore, the plan currently in force, any relevant made neighbourhood plan and the 2026 National Planning Policy Framework continue to guide decisions.
Local planning guidance
How does the Local Nature Recovery Strategy apply to Lincoln?
Lincolnshire County Council published the Greater Lincolnshire LNRS on 31 July 2026. It covers Lincoln City, Lincolnshire's districts and the two separate North/North East Lincolnshire unitary areas. The mapped priority actions—some of the strategy's 184 actions—inform strategic significance and habitat restoration. Central Lincolnshire's own Biodiversity Opportunity Mapping remains relevant and the authority's guidance explains how final LNRS mapping expands and clarifies it, rather than automatically replacing its adopted planning policy.
The Greater Lincolnshire Local Nature Recovery Strategy was published 31 July 2026, with Lincolnshire County Council as responsible authority. Its Local Habitat Map identifies existing important habitats and locations where specified measures can support nature recovery.
An ecologist must test whether a proposed enhancement genuinely matches the relevant mapped measure. An LNRS opportunity polygon cannot replace a field survey, create units automatically or make a habitat gain site legally registered. Download the current map and retain its source/date when justifying strategic significance.
Local planning guidance
Local habitats and site considerations
Use habitats within and connected to your site to scope surveys and retain important ecological connections.
What makes biodiversity assessment locally specific?
Lincoln's River Witham, Brayford Pool and connecting urban green corridors can support riparian vegetation, wetland pockets and water-dependent species. Parks, conservation green space, older tree cover and mapped Green Wedges also influence biodiversity design. Development on former industrial or compact urban land should still survey trees, scrub, grassland and potential watercourse impacts. Floodplain and drainage design need appropriate hydrological and ecological evidence rather than a token wildlife-garden scheme.
Under adopted S60 and S66, locally designated wildlife sites, priority habitats, protected trees and potentially important hedgerows should be retained where feasible. River Witham proposals may need river condition or aquatic habitat methods. Not every city parcel is an internationally designated wetland; any Habitats Regulations or protected species requirement depends on the real site and possible effects, with legal obligations separate from area habitat units.
Protected-species licensing, statutory site impact assessment, woodland or tree protection and any relevant watercourse assessment remain separate from BNG. A development exempt from the statutory condition may still need to avoid or mitigate ecological harm.
How should Lincoln development opportunities be approached?
Lincoln's Brayford waterfront and River Witham urban public realm present useful design contexts for water, trees, green roofs and pedestrian accessibility. Nevertheless, a historic regeneration ambition is not proof of habitat-unit delivery. The adopted Central Lincolnshire plan's Lincoln area site allocations and Green Wedges must be checked at the actual parcel. Urban expansion outside the City Council boundary may instead be determined by North Kesteven or West Lindsey under the shared plan.
Why local BNG information can be needed on a legally exempt site
Central Lincolnshire’s current biodiversity guidance asks for its Biodiversity Gain Statement with all planning applications, including those which are exempt from mandatory BNG. This is an explanation of the planning route, not a legal requirement for every exempt site to purchase units. Its 2026 update also discusses additional evidence where a site falls within mapped Biodiversity Opportunity Mapping or published LNRS actions. The proposed new local validation lists were still under consideration, so applicants should use the formally adopted list and record the correct national exemption.
For a constrained scheme, first map existing vegetation, watercourses and habitats, then compare the proposed layout with avoidance and retention options. Habitat creation must suit soils, drainage, shading, public access and achievable long-term management. Do not infer biodiversity condition from the former industrial or agricultural land use.
Local planning guidance
What can applicants learn from local evidence?
The Central Lincolnshire joint planning partnership published detailed BNG supporting guidance after adopting S61 in 2023 and expanded it in August 2026 to address national exemptions, future habitat management and the published LNRS. The published guidance includes a Biodiversity Gain Statement, metric expectations and an illustrative monitoring-fee calculator. This is an actual authority implementation example—not evidence of saleable council units or a completed developer habitat project.
Local planning guidance
What BNG evidence does City of Lincoln Council expect?
For development subject to statutory BNG, the national application-stage information normally includes:
- Whether the applicant considers the biodiversity gain condition applicable, with reason if exempt.
- The pre-development biodiversity value, completed appropriate published statutory metric, and version/publication date.
- Any earlier baseline date and reasons where relevant.
- Details of habitat degradation and earlier calculations where applicable.
- Any irreplaceable habitat on the red-line site.
- A scaled map showing current onsite habitats and a north point.
Central Lincolnshire's Biodiversity Gain Statement is a local validation document for all applications, including statutory BNG-exempt categories. It helps an applicant explain the applicable exemption or evidence, but it does NOT mean every exempt householder must purchase biodiversity units. For in-scope applications, a statutory pre/post metric workbook and habitat/condition evidence may be needed. The May–June 2026 proposed validation-list revisions remained unadopted by November; use the actually adopted list and current 6 August BNG statement revision.
Additional ecology or landscape reports may be necessary and proportionate for specific impacts. Confirm the current council validation checklist and application type rather than assuming one universal report package. The final Biodiversity Gain Plan is normally approved after planning permission, before commencement, rather than being required universally with the first application.
For help commissioning evidence, see our BNG assessment service and habitat surveys.
Local planning guidance
What are the current statutory rules?
Qualifying development in England normally needs 10% statutory BNG. From 6 August 2026, a new application on a whole development site of 0.2 hectares or less can be exempt where no onsite priority habitat is adversely affected. Certain wholly temporary schemes lasting five years or less may also qualify; the former dedicated self/custom-build exemption no longer applies to new applications. Older cases and section 73 permissions require their own transitional assessment.
The 29 September 2026 NPPF, policies N1(2) and N2(3), restricts mandatory local BNG requirements above the statutory level to specific, justified and deliverable allocations. A general aspiration to improve biodiversity should not be misrepresented as an adopted blanket 20% requirement.
The latest government statutory metric, as at 10 November 2026, is v1.1.1, updated 10 November 2026. GOV.UK permits any published statutory metric version where appropriate; pre-statutory Metric 4.0 is not an accepted mandatory tool. An eligible smaller scheme may instead use the separate Small Sites Metric.
For decision criteria, see our BNG exemptions guide and statutory biodiversity metric service.
Local planning guidance
What if suitable biodiversity gains cannot be delivered onsite?
Central Lincolnshire's guidance currently states that its own local council listing has no gain sites approved/secured for listing at the time of its update. This does not prove no registered units exist anywhere within Lincolnshire or on the government's register. A genuine Lincoln application needing offsite units must check registered gain-site type, allocated available stock, trading rules and current legal agreement; local council lists and LNRS potential measures alone are not legal unit supply.
For major development, appropriate onsite creation/enhancement normally has priority under the national gain hierarchy. For qualifying non-major applications made from 6 August 2026, onsite and registered offsite gains may be considered at an equivalent hierarchy level. Statutory biodiversity credits remain the last resort.
Any proposed offsite units must meet habitat-trading, spatial-risk, legal agreement, government gain-site registration and allocation rules. A local supplier's brochure, LNRS opportunity map or projected bank cannot demonstrate current saleable units. Significant onsite and registered offsite gains generally require at least 30 years of secure habitat management.
Our offsite biodiversity units guide and Habitat Management and Monitoring Plan service explain the respective stages.
Your site checklist
Seven checks before commissioning a BNG calculation
Use these seven checks to prepare a proportionate brief for your site assessment and planning submission.
| Check | Site evidence | Why it matters |
|---|---|---|
| Planning authority | Confirm the red-line boundary and the actual decision-maker: City of Lincoln Council; check any separately identified planning geography. | Select the correct adopted plan, map and application validation list. |
| BNG applicability | Record the application date, whole site hectares, onsite priority habitats, development type and any earlier or section 73 permission. | Test the legally correct exemption, transition and delivery hierarchy. |
| Surveyed habitat | Obtain UKHab parcels, habitat conditions, hedgerows, watercourses, trees, photographs and protected-species evidence. | Determine survey scope, habitat condition and appropriate statutory metric modules. |
| Published LNRS | Check the Greater Lincolnshire Local Nature Recovery Strategy current Local Habitat Map and the exact matching habitat measure, not just an opportunity colour. | Justify the proposed measure against the published LNRS map and site location. |
| Protected sites | Check mapped green wedge S63 and trees/hedgerows S66, River Witham/watercourse features, and Central Lincolnshire local Biodiversity Opportunity Mapping and published Greater Lincolnshire LNRS measure at site. | Identify HRA, protected species, watercourse or other separate safeguards. |
| Gain-delivery route | Test viable onsite habitat, current habitat trading, genuine government-registered off-site allocation and significant enhancement management. | Check actual habitat trading, registered allocations, spatial risk and feasible habitat creation. |
| Application and stewardship | Use the appropriate council's application documents and prepare final gain-plan and long-term management at the right stage. | Align initial evidence, postpermission gain-plan approval and long-term stewardship. |

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.
What should a Lincoln project budget for?
Central Lincolnshire publishes a BNG monitoring-fee calculator/overview for significant gains, including an update from 6 August 2026. Charges depend on the actual monitoring and legal obligations, rather than a universal Lincoln price for units. Keep potential local monitoring costs distinct from statutory application charges, the ecological survey/metric work, registered offsite units, and any tree or river condition assessment.
Keep the costs of UKHab and condition surveys, the statutory metric, targeted protected-species work, registered offsite biodiversity units, legal obligations, and long-term habitat monitoring separate. These are not interchangeable fees. No generic market price can replace an actual quotation, and a council fee documented for a protected-site scheme is not the price of statutory BNG units.
A final Biodiversity Gain Plan for qualifying permission normally comes after consent and before commencement. Significant gains need realistic legal stewardship and a suitable habitat management/monitoring plan, often for at least 30 years.
Read our Biodiversity Gain Plan guide and BNG cost categories.
Practical assessment steps for Lincoln
First — establish the planning context. Supply the development boundary, proposals, expected application date and known planning authority. Identify current adopted policy, national BNG applicability, LNRS territory and any important constraints.
Next — survey and calculate. Scope UKHab, habitat condition, area/hedgerow/watercourse modules and, where justified, protected-species or Habitats Regulations work. Record metric version and survey assumptions transparently.
Then — plan realistic delivery. Seek habitat retention and appropriate onsite design. Assess any registered offsite shortfall and long-term management needs, without promising units or planning permission before a defensible assessment.

Frequently asked questions
These answers cover common planning, habitat and delivery questions for projects in Lincoln.
Does Lincoln City use the Central Lincolnshire Local Plan?
Yes. City of Lincoln Council determines city applications, while the Central Lincolnshire Local Plan adopted 13 April 2023 provides the shared statutory planning policies with North Kesteven and West Lindsey. Those districts remain separate planning authorities.
Which adopted Lincoln policy requires biodiversity improvements?
Policy S61 Biodiversity Opportunity and Net Gain is the specific adopted 2023 local BNG policy. S60 protects biodiversity/geodiversity and S66 covers trees, woodland and hedgerows, with S63 relating to mapped Green Wedges.
Is a Biodiversity Gain Statement needed for a statutory-exempt application?
Central Lincolnshire's published supporting documents say its local Biodiversity Gain Statement applies to all applications, including statutory-exempt categories. It is an information declaration; it does not automatically impose the statutory 10% gain condition on exempt development.
Has the new 2026 Central Lincolnshire validation list been adopted?
Not by this review date. The consultation on proposed validation-list updates closed 7 June 2026, and the planning team said the currently adopted lists remained in force until replacements were adopted. Verify any later formal adoption.
Does the Greater Lincolnshire LNRS replace S61 biodiversity opportunity mapping?
No. The shared LNRS published July 2026 adds mapped measures and helps strategic significance. Central Lincolnshire's guidance says it expands and clarifies its Biodiversity Opportunity Mapping rather than automatically removing it.
Are offsite biodiversity units available from Lincoln Council's published list?
The Central Lincolnshire webpage currently says it has no local gain sites approved or secured for its own listing. That is not proof the national register has no relevant sites or units. Real availability and legal allocation need a project-specific register check.
Must the proposed 2026 Central Lincolnshire validation checklist be used already?
Not automatically. The council consulted on revised local validation lists in May and June 2026 but said that the existing adopted lists remained operative until replacements were adopted. Check the latest formal adoption for the actual application category.
Is a local monitoring fee the same as the price of an offsite biodiversity unit?
No. Central Lincolnshire publishes a monitoring fee overview and calculator for the council's work on significant gains. A registered offsite unit purchase is a separate commercial/legal transaction, with its own habitat type, allocation and spatial-risk assessment.
Does every Lincoln development need 10% Biodiversity Net Gain?
No. Qualifying development normally needs 10%, but the legal exemptions and transitions are important. New applications from 6 August 2026 can qualify for the conditional exemption on a site of 0.2 hectares or less where no onsite priority habitat is adversely affected. Protected species and habitats can require separate evidence.
Can a small site in Lincoln use the Small Sites Metric?
Only if the development and habitats meet the government's Small Sites Metric eligibility rules. Site area or number of dwellings alone does not decide this. The main statutory metric may be required instead, particularly where sensitive habitats or other exclusions apply.
When is the final Biodiversity Gain Plan approved in Lincoln?
For eligible permissions the final Biodiversity Gain Plan is normally submitted and approved after planning permission and before development starts. The original application needs the national baseline information plus any necessary and proportionate evidence required under the correct authority's current validation list.
Can I purchase off-site biodiversity units for a Lincoln project?
Potentially, provided the units meet the relevant habitat-trading, registration, legal allocation and spatial-risk rules. Availability, unit classes and prices have to be checked for the actual scheme. A supplier's website or nature-recovery map is not proof of available allocated units.
