Sunderland BNG advice
Biodiversity Net Gain in Sunderland
Plan your Sunderland 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 Sunderland site.
Local planning
Adopted policies: connect each requirement to the design
Sunderland adopted its Core Strategy and Development Plan 2015–2033 on 30 January 2020. Relevant saved Unitary Development Plan policies and the adopted IAMP Area Action Plan also form part of the planning framework. The council reviewed the Core Strategy in December 2024.
| Reference | Planning issue | What the applicant should coordinate |
|---|---|---|
| NE1 | Green and blue infrastructure | Map existing connections and strengthen gaps where feasible. Coordinate habitat links with drainage, access and public open space. |
| NE2 | Biodiversity and geodiversity | Explain avoidance, mitigation and measurable enhancement. Address designated sites and species alongside the habitat calculation. |
| NE3 | Woodland, hedgerows and trees | Align ecological evidence, tree protection and landscape drawings. Examine ancient woodland and veteran-tree implications separately. |
| NE4 | Greenspace | Check the function and policy protection of existing open space before assigning it to development or habitat delivery. |
| NE10 | Heritage Coast | Check the mapped coastal context and the proposal’s effects on its natural character and interests. |
| ID2 | Planning obligations | Agree the delivery, funding and monitoring arrangements needed to make the proposal acceptable. |
Read the operative policy wording through the adopted Core Strategy gateway. The responses above are practical design prompts. A metric result alone does not answer every planning policy test.
Recent planning changes
A new Local Plan is being prepared
The 2026 process is an emerging plan
The council’s scoping consultation closed on 29 September 2026. Its Gateway 1 self-assessment was published on 30 October 2026, starting the new plan preparation period. The programme identifies a proposed further consultation in June 2027.
Use the current Local Plan programme to follow changes. Record the adopted and emerging policy positions separately when preparing an application. Proposed dates can change as the plan develops.
The IAMP replacement draft was withdrawn
The existing IAMP Area Action Plan was adopted in November 2017. Sunderland’s Cabinet resolved on 25 June 2026 to revoke the later draft replacement and associated evidence base. The councils are instead pursuing comprehensive Local Plans.
The council’s IAMP update distinguishes the adopted framework from the withdrawn draft. For an IAMP proposal, confirm the site boundary and current adopted policies before using an older consultation document.
Application guidance
Use the adopted guidance and a dated validation list
Supplementary guidance
The council’s adopted library includes the Development Management SPD, South Sunderland Growth Area SPD and Riverside Sunderland SPD. These help connect the site’s planning context with design, infrastructure and open-space decisions.
The Planning Obligations SPD was adopted on 18 September 2025. Start with the adopted SPD library so that a superseded 2020 obligations document or a consultation draft does not enter the application evidence.
What the local checklist asks for
Section 15 of the published validation checklist describes baseline and proposed habitat plans, an editable metric workbook and a BNG assessment report with condition evidence. It also addresses protected species, ecological impact assessment and HRA.
The checklist is dated 15 January 2024. Apply it alongside the current national rules, particularly the August 2026 exemption changes. Confirm any updated local requirements with the council before submission.
Nature recovery
Use the South of Tyne and Wear nature recovery strategy
Sunderland falls within the South of Tyne and Wear Local Nature Recovery Strategy, alongside Gateshead and South Tyneside. Gateshead Council is the responsible authority. Sunderland’s current nature page confirms formal adoption in September 2026.
Start with the mapped parcel
The strategy combines biodiversity priorities with a Local Habitat Map. Use the council’s LNRS gateway to reach the published strategy and NaturePlan map. Identify the measure that relates to the actual land.
For a Wear-side proposal, test water and bank connections. For a woodland or grassland proposal, examine soils, shading and adjacent habitats. A broad opportunity area still needs field evidence and a deliverable management approach.
Explain strategic significance clearly
Where the statutory metric permits, a relevant published LNRS measure can support the strategic significance entry. Retain a dated map extract, identify the proposed habitat intervention and explain how it matches that measure.
Discuss uncertain boundaries or habitat matches with the council’s ecologist. The map helps prioritise recovery; it does not establish habitat condition, grant planning permission or confirm that off-site units are available.
Local habitat evidence
Different local settings need different survey decisions
The following places provide useful scoping prompts. Their regional habitat character does not prove what occurs on an individual development site. Confirm the red line, survey access and any ecological connection before commissioning specialist work.
| Local setting | Questions for the site assessment |
|---|---|
| River Wear and adjoining land | Identify riverbank vegetation, trees, wetland connections and any affected watercourse. Coordinate ecological survey limits with drainage and engineering drawings. |
| Roker, Seaburn and the coast | Check coastal designations and potential disturbance pathways. Consider access, lighting and recreation alongside direct habitat effects. |
| Washington and its wetland connections | Examine ponds, streams, tree belts and links to surrounding habitats. Confirm the actual pathway before assuming effects on a nearby wetland. |
| Hylton Dene and wooded corridors | Identify woodland edges, mature trees, scrub and connected habitats. Resolve access, root protection and lighting before fixing the layout. |
| Houghton, Hetton and former industrial land | Survey grassland, hedgerows, disturbed substrates and habitat mosaics before clearance. Previous development does not establish a low ecological value. |
The council’s natural environment map gateway helps locate designated sites. Supplement mapping with appropriate records and current fieldwork. Survey season, land access and the proposed works determine the practical programme.
Protected sites
Address coastal protection alongside the BNG calculation
Check a real impact pathway
The Durham Coast SAC and Northumbria Coast SPA and Ramsar interests can require separate consideration. New residential development may create recreation pressures as well as direct habitat effects. Establish the applicable zone and mitigation approach with the council.
The adopted obligations guidance describes strategic recreation mitigation. A BNG exemption does not remove protected-site duties. Keep the habitat metric, protected-species evidence and any Habitats Regulations Assessment clearly connected in the submission.
Coordinate access, lighting and drainage
A layout may retain habitat yet introduce disturbance through lighting, access or surface-water discharge. Test these effects while design choices remain flexible. Confirm how any required mitigation will be delivered and maintained.
Use the Planning Obligations SPD ecology chapter and national appropriate assessment guidance for the relevant processes. Buying biodiversity units does not itself resolve a protected-site impact.
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.
Planning evidence
Build one consistent planning evidence package
Use the same habitat parcel references across plans, condition sheets, the metric and the report. This makes the assessment easier to review and reduces discrepancies when the design changes. The council’s local checklist should be checked alongside national minimum submission information.
| Stage | Documents and decisions |
|---|---|
| Before design is fixed | Confirm BNG applicability and the baseline date. Obtain habitat and condition evidence, identify constraints and agree any further surveys. |
| Planning application | Provide the required baseline information and metric. Coordinate proposed habitat plans, ecology reports, landscape drawings and the strategy for any shortfall. |
| After permission, before commencement | Where the biodiversity gain condition applies, obtain approval of the Biodiversity Gain Plan. Resolve legal security and off-site allocation evidence in time. |
| Habitat delivery and management | Set measurable habitat targets, responsibilities, monitoring dates and remedial actions. Keep the management plan consistent with the approved metric. |
Our BNG assessment guidance explains the technical package. A landscape drawing can support design coordination, but the habitat plan still needs clear classification, areas and parcel references.
Habitat banks and units
Investigate off-site delivery against a defined shortfall
A documented local habitat-bank route
Sunderland’s Biodiversity Report 2023–2026 records work with Durham Wildlife Trust on council habitat banks. It also records registration of part of Rainton Meadows for off-site delivery supporting housing at Farringdon Row in Riverside Sunderland.
This is a useful documented local delivery example. It does not establish spare units for another project. Ask for the register reference, unallocated habitat units, delivery dates and the agreement covering the land.
Check the unit type and location
Calculate the shortfall by habitat account before contacting a supplier. Area habitat, hedgerow and watercourse units have distinct rules. The applicable spatial multiplier depends on the relevant geography and metric account.
Check the national biodiversity gain-site register and obtain current supplier evidence. Our off-site units guide explains allocation, legal security and the information needed before committing to a purchase.
Costs and responsibilities
Separate council monitoring charges from delivery costs
The adopted September 2025 Planning Obligations SPD publishes BNG monitoring base rates by monitorable area and technical difficulty. Its figures are expressly labelled 2025 and subject to annual review. Confirm the current indexed charge with the council; these are not a 2026 quotation.
| Area monitored | Low difficulty | Moderate difficulty | High difficulty |
|---|---|---|---|
| 0–5 hectares | £2,582.41 | £3,095.61 | £3,654.62 |
| Over 5–15 hectares | £3,547.89 | £4,078.59 | £4,516.16 |
| Over 15–30 hectares | £6,239.23 | £7,309.24 | £9,473.90 |
Figures 5 and 6 of the adopted SPD also identify separate 2025 software and financial-obligation monitoring fees of £33.67 and £89.00. Areas above 30 hectares require a bespoke fee. Confirm the applicable additions, phasing and indexation in writing.
Budget for the work on the ground
Survey and reporting fees depend on the land, access, seasonal work and planning stage. Habitat creation, establishment, ongoing management and ecological monitoring need separate budgets. Include remedial work if target condition is not achieved.
Council monitoring charges pay for the authority’s role. They do not buy biodiversity units or cover the landowner’s management work. Ask each quotation to identify the tasks, assumptions and exclusions.
Allow for the agreement and allocation
Legal work, registration, supplier units and any applicable planning contributions are separate cost categories. Establish who pays each item and when it is due. A headline unit price can omit costs that matter to the project.
No live Sunderland unit-price quotation is presented here. Obtain a dated offer for the required habitat account and location. Statutory credits are a separate national last-resort route.
Local delivery lessons
What published local delivery evidence shows
Plan approval and habitat outcomes are different stages
For 12 February 2024 to 1 January 2026, the council reports 34 permissions requiring statutory BNG and six approved gain plans. Two gain plans used on-site units alone; four combined on-site and off-site units.
These reported approvals show why a project needs a delivery route beyond the planning decision. They describe expected provision, rather than demonstrating that every habitat has already reached its target condition.
Use regeneration guidance to resolve interfaces
Riverside Sunderland and the South Sunderland Growth Area have adopted supplementary guidance. For a scheme in either area, coordinate its ecology strategy with the relevant masterplan, infrastructure and open-space proposals.
Use the adopted guidance library to establish the relevant document and boundary. Then check who controls the habitat land and how works, access and management align with neighbouring phases. These are applicant considerations, not claims of ACP involvement.
Long-term delivery
Make the habitat commitments workable for the long term
Secure the right land and responsibilities
Significant on-site gains and registered off-site gains require at least 30 years of maintenance under the statutory arrangements. Establish the responsible party, legal mechanism and applicable start date before relying on those gains.
A management company, landowner or habitat provider needs clear duties and funding. Keep access for monitoring and remedial works practical. Review obligations when land ownership or development phasing changes.
Write targets that can be inspected
Describe the intended habitat, target condition, management actions and monitoring schedule. Specify what happens if establishment fails or condition falls below the agreed target. A useful plan enables another ecologist to assess progress consistently.
Our Habitat Management and Monitoring Plan guide explains the documentation. Coordinate it with landscape and drainage maintenance so that routine operations support the ecological outcome.

Common local questions
Sunderland Biodiversity Net Gain FAQs
Which council deals with a Sunderland BNG application?
Sunderland City Council normally handles applications across Sunderland, Washington, Houghton-le-Spring and Hetton-le-Hole. Confirm the red-line boundary and any special site framework. IAMP extends across Sunderland and South Tyneside.
Which adopted policies should my assessment address?
Start with Core Strategy policies NE1, NE2 and NE3 for green infrastructure, biodiversity and trees. NE4, NE10 and ID2 may also matter. Check saved UDP policies, the policies map and any applicable IAMP framework.
Has the new Sunderland Local Plan replaced the Core Strategy?
No. The council published its Gateway 1 self-assessment on 30 October 2026. The replacement plan is being prepared. Record its emerging status separately from the adopted development plan.
Which nature recovery strategy covers Sunderland?
The South of Tyne and Wear Local Nature Recovery Strategy covers Sunderland, Gateshead and South Tyneside. Sunderland’s council page confirms adoption in September 2026. Use the published habitat map and relevant measures for the actual site.
Can a small Sunderland development be exempt from BNG?
A conditional exemption applies to applications from 6 August 2026 where the red-line area is 0.2 hectares or less. It does not apply where on-site priority habitat is adversely affected. Other exemptions and transitional rules also need checking.
Does an exemption remove the need for ecology evidence?
No. Protected species, designated sites, trees and local planning policies may still require evidence. Explain the exemption separately and scope surveys against the proposed works and the site’s actual features.
Can I buy units from a Sunderland habitat bank?
A council report records local habitat-bank work and a Rainton Meadows delivery example. Current availability must be confirmed with the provider. Check registration, unallocated unit types, spatial rules, legal security and allocation before relying on an offer.
How much is the council’s BNG monitoring fee?
The adopted September 2025 SPD publishes base rates by monitored area and technical difficulty, with additional charges and annual review. Obtain the current indexed amount from the council. These charges are separate from ecological consultancy, habitat management and unit purchases.
When must the Biodiversity Gain Plan be approved?
Where the biodiversity gain condition applies, the planning authority must approve the gain plan before development begins. Prepare the delivery evidence early so that legal agreements, habitat management and any off-site allocation do not delay commencement.
What should I send ACP for a Sunderland assessment?
Send the red-line plan, address or grid reference, proposed works and planning stage. Include any habitat surveys, tree reports, landscape plans and council correspondence. These help identify the appropriate scope and avoid duplicated work.
