Local planning guidance
Who decides development applications in Chesterfield?
Chesterfield Borough Council decides ordinary planning applications within the borough. Derbyshire County Council manages separate minerals/waste planning and leads the shared Derbyshire-and-Derby LNRS, while North East Derbyshire and Bolsover authorities determine adjoining land beyond the borough boundary. Some housing schemes marketed as Chesterfield lie outside the borough, so the planning authority must be confirmed from the red-line map and council policies map.
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 Chesterfield?
Chesterfield Borough Local Plan 2018–2035 was adopted 15 July 2020. Policy CLP15 Green Infrastructure protects and connects strategic parks, natural sites and green corridors. CLP16 Biodiversity, Geodiversity and the Ecological Network requires avoiding adverse ecological effects, protecting protected/priority sites and creating suitable habitat improvements. CLP18 Chesterfield Canal and CLP19 River Corridors are relevant to actual canalside or river sites, while strategic regeneration site policies SS3 and SS5 guide mapped areas.
| Adopted policy or document | What it covers | Practical implication for the application |
|---|---|---|
| CLP16 — Biodiversity, Geodiversity and the Ecological Network | Adopted Chesterfield Local Plan July 2020 | Protect and enhance protected sites, priority habitat, species and ecological networks; demonstrate mitigation and suitable gain. |
| CLP15 — Green Infrastructure | 2020 adopted Local Plan | Retain/connect parks, green wedges and strategic ecological routes; secure maintenance for new green infrastructure. |
| CLP18 / CLP19 — Chesterfield Canal and River Corridors | 2020 adopted Local Plan | Consider banks, hydrology, watercourse and canal heritage/ecology on relevant parcels; assess specialist watercourse metric if needed. |
| SS3 / SS5 — Waterside and Staveley/Rother Valley strategic sites | 2020 adopted Local Plan strategic allocations | For actual strategic site boundaries, integrate BNG with redevelopment, open space, blue-green corridor and flood design. |
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?
Chesterfield began preparation of a new Local Plan for 2025–2044 in 2026 under the revised plan-making system. Formal Gateway 1 began 21 September 2026, following scoping engagement in June–July; later consultation on content and evidence was timetabled for October–November 2026. The new plan is only emerging and has not replaced the adopted July 2020 CLP16 or river-corridor policies. Future planned adoption dates are provisional milestones, not planning decisions.
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 Chesterfield?
The shared Derbyshire and Derby LNRS was published September 2025 and covers Chesterfield Borough as part of Derbyshire. It identifies habitat connectivity, restoration of grassland, woodland, watercourses and nature recovery priorities across urban and rural landscapes. The Local Habitat Map should support a Chesterfield scheme only where the actual habitat intervention corresponds to a mapped measure; the county's responsible-authority role does not replace borough planning decisions.
The Derbyshire and Derby Local Nature Recovery Strategy was published September 2025, with Derbyshire 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?
Chesterfield Canal, River Rother and tributary valleys offer connected blue-green routes, including floodplain and riparian woodland/grassland. Poolsbrook Country Park and some former industrial land illustrate the potential for ecological restoration alongside recreation. Historic railway, former coal and industrial sites can host valued urban mosaic habitats. Borough planning CLP16/CLP19 requires actual field habitat condition and protected species work where a project impacts such features.
Chesterfield Borough's adopted CLP16 protects internationally, nationally and locally important habitats and species, including land meeting criteria for Local Wildlife Sites or priority habitat, even where no statutory site designation has been formally assigned. A river/canal-side proposal may affect watercourses, bats, birds or trees. Such impacts may require separate surveys and licensing; BNG metric units do not automatically resolve ecology legal duties.
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 Chesterfield development opportunities be approached?
The adopted Chesterfield Local Plan contains SS3 Chesterfield Waterside and the Potteries and SS5 Staveley and Rother Valley Corridor strategic allocations. These are useful planning contexts for mixed-use redevelopment, blue-green infrastructure and river-edge habitat design. Actual scheme proposals must be checked against approved consents, red-line boundaries, flood risk, canal and river condition; an adopted allocation is not proof a particular habitat project has been delivered.
Waterside and Staveley: the adopted corridor policies are different
Chesterfield’s 2020 adopted plan distinguishes SS3 Chesterfield Waterside and the Potteries from SS5 Staveley and the Rother Valley Corridor. Both require applicants to work with the actual mapped strategic context, but they are not interchangeable housing schemes. CLP18 addresses the canal and CLP19 covers river corridors, so an applicant may need separate watercourse condition, bank vegetation and protected species evidence. Neither adopted site allocation proves a future habitat scheme has been delivered or registered as BNG units.
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?
Chesterfield's 2020 adopted Local Plan uses the Canal and River Rother corridors as explicit ecological and regeneration policy routes. It identifies the Chesterfield Waterside and Potteries and Staveley–Rother Valley Corridor as strategic site areas that should integrate growth with connected green infrastructure.
Local planning guidance
What BNG evidence does Chesterfield Borough 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.
Chesterfield Borough Council's BNG applicant webpage describes statutory metric and ecology evidence and later Biodiversity Gain Plan approval. Some council summaries still mention the former self-build exemption and an LNRS that was 'being prepared'; these statements predate the 6 August 2026 law and September 2025 final LNRS publication. Use the current national rules, adopted CLP16, actual council validation list and justified ecological surveys for a specific proposal.
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?
The Derbyshire/Derby LNRS and adopted Chesterfield ecological network policies identify possible habitat delivery opportunities, but neither source is a government register of saleable units. An urban Waterside scheme unable to meet full 10% onsite may investigate registered offsite gains under the current hierarchy and habitat trading rules, but availability, legal agreements, unit class and spatial risk must be verified on the actual official register.
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: Chesterfield Borough 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 Derbyshire and Derby 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 borough CLP16/CLP19, mapped river Rother/canal corridor, bats/watercourse habitat and floodplain impacts; do not infer every Chesterfield parcel contains these features. | 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 Chesterfield project budget for?
For a Chesterfield development, distinguish the statutory UKHab/metric, canal or River Rother condition, targeted protected-species work and potential tree assessments from gain-site purchase and long-term habitat management. The council has referred to BGP application fees in historic guidance, but that is not a verified current 2026 charge. Use the authority's up-to-date fee schedule before quoting an amount.
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 Chesterfield
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 Chesterfield.
Is Chesterfield planning handled by Derbyshire County Council?
No, most ordinary Chesterfield development is determined by Chesterfield Borough Council. Derbyshire County Council leads the shared LNRS and has separate minerals/waste responsibilities, while neighbouring North East Derbyshire and Bolsover councils have their own plans.
Which adopted Chesterfield policy addresses biodiversity?
The adopted Chesterfield Borough Local Plan 2018–2035 includes CLP16 Biodiversity, Geodiversity and the Ecological Network, supported by CLP15 Green Infrastructure and CLP18/CLP19 for canal and river corridors where relevant.
Is the new 2025–2044 Chesterfield Local Plan in force?
No. The council began the new process in 2026 and reached Gateway 1 on 21 September. The existing July 2020 adopted plan remains operative until a replacement is formally adopted.
Does the Chesterfield Canal automatically increase BNG units?
No. The canal is an ecological and heritage corridor, but metric unit calculations depend on mapped watercourse, adjacent habitat condition and a matching proposed intervention. Separate watercourse and species assessments may also be necessary.
Are Chesterfield Waterside and Staveley projects completed BNG case studies?
They are adopted strategic development policy areas, not automatic evidence of realised statutory biodiversity-unit delivery. Check each actual planning permission, habitat survey and legal allocation before citing a scheme as a measured case study.
Which LNRS covers Chesterfield and when was it published?
Derbyshire County Council published the Derbyshire and Derby LNRS in September 2025. Its mapped measures can guide habitat opportunities, but parcel-level UKHab and policy CLP16 remain essential.
Which adopted Chesterfield policies cover Waterside and the Staveley corridor?
The adopted 2020 Local Plan includes SS3 for Chesterfield Waterside and the Potteries, SS5 for Staveley and the Rother Valley Corridor, CLP18 for the Canal and CLP19 for River Corridors. Each applies only where the site actually intersects its policy area.
Does every Chesterfield 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 Chesterfield 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 Chesterfield?
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 Chesterfield 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.
