Local context / Sources, monitoring and exposure
The local context for your development
Putney High Street and Tooting
Review street-facing façades, buses, queues and servicing against a suitable monitoring record. The two corridors have different histories, and missing monitoring years should remain visible.
Wandsworth town centre and Battersea
Consider road networks, phased development and nearby occupied buildings. For a relevant riverside site, include the actual relationship with vessel activity or heliport operations rather than assuming a borough-wide effect.
Works, ventilation and plant
Connect demolition and earthworks controls to nearby homes and businesses. Keep construction access, dust monitoring, energy plant and ventilation choices consistent with the noise assessment and design drawings.
AQMA / Current designation
The whole borough is designated
Defra records a whole-borough AQMA from 1 January 2001 for annual NO₂ and daily PM₁₀. The chart shows later historical roadside NO₂ exceedances. Recent values below an objective do not automatically revoke the designation.
Defra / Newer reporting evidence
Keep the dashboard and network counts separate
Defra’s 2025 dashboard shows 62 of 62 included NO₂ records compliant. These are submitted reporting records, not a census of all instruments, tubes or local sensors.
02 / Monitoring evidence
Local measurements, clearly explained
Putney High Street · 2024
Annual NO₂, µg/m³. Annualised; 68% full-year capture.
Tooting High Street · 2024
Annual NO₂, µg/m³. 95% full-year capture.
Diffusion-tube locations
The 2024 report’s non-automatic network, separate from indicative sensors.
The monitoring network
The 2024 report and council update describe five automatic stations and 55 non-automatic monitoring sites. Reference equipment was replaced during 2024. Breathe London sensors provide additional indicative NO₂/PM₂.₅ evidence and should remain separate from the reference-station series.

Annual values and data capture
| Year | Putney High Street | Tooting High Street |
|---|---|---|
| 2018 | 68 | 53 |
| 2019 | 69 | 50 |
| 2020 | 58 | 35 |
| 2021 | 62 | 34 |
| 2022 | No valid annual result | 34 |
| 2023 | No valid annual result | 33 |
| 2024 | 37 | 31 |
| 2024 capture | 68% | 95% |
Tooting High Street fell from 50 in 2019 to 31 µg/m³ in 2024. Putney High Street’s 2024 reported mean was 37, with insufficient valid annual data in 2022 and 2023. The gap is retained rather than joined by an invented trend.
Putney’s 2024 full-year capture was 68%, requiring annualisation; Tooting achieved 95%. Tooting’s 2020–2023 values are also flagged as annualised in Table D. Compare like-for-like records and retain the report’s quality qualifications.
Street-level evidence / Diffusion tubes
Where higher roadside concentrations remain
The council’s 2024 report identifies eight tube locations above its 30 µg/m³ interim ambition. This is distinct from the national annual NO₂ objective of 40 µg/m³.
| Tube site | 2023 | 2024 |
|---|---|---|
| W4Mitcham Road | 42 | 34 |
| YR5Battersea Park Road | 42 | 37 |
| W47West Hill | 53 | 48 |
| W42Bellevue Road | 33 | 33 |
| YR2Royal Academy of Dance, York Road | 35 | 32 |
| W23West Hill | 33 | 31 |
| W24Putney McDonalds | 38 | 34 |
| NE3Queenstown Road | 32 | 31 |
Rounded, bias-adjusted monitor-location values from Table F, page 29. The network’s mean capture was 94%; the report identifies WH2 as the sole tube requiring annualisation.
West Hill W47 was the only tube location above 40 in 2024. The receptor calculation uses 47.5 µg/m³ at the monitor and predicts 33.4 at the relevant exposure point. Table F rounds the monitor result to 48. These are different locations and precision levels, not conflicting measurements.
Background / Appropriate evidence
A roadside result is not the borough background
The Battersea Park tube NE8 recorded 12 µg/m³ NO₂ in both 2023 and 2024. Compare the source setting, capture, measurement height and exposure location before transferring evidence to a proposed façade.
Use the appropriate assessment-year background maps and suitable ratified local data. Keep the additional contribution from road traffic, plant, construction or relevant river and heliport activity identifiable.
Particles and other pollutants
PM₁₀ · reference monitoring
2024 annual means were 16 at Putney High Street, 14 at Felsham Road, 17 at Thessaly Road and 20 at Tooting High Street, in µg/m³. Full-year capture was 84%, 95%, 80% and 90% respectively. Retain separate daily-objective checks.
PM₂.₅ · indicative sensors
Table J reports a 2024 mean of 8.11 µg/m³ across 15 Breathe London sites with more than 80% data. The participating network changed between years; this is not a fixed-network trend or a reference compliance result.
Scope around the proposal
Consider dust and particle emissions alongside NO₂. Include odour, combustion pollutants or ecological exposure where the activity and receptor pathway make them relevant. Keep monitoring method and benchmark explicit.
Read particle results and monitoring qualifications · Tables H–K
Turn the evidence into a site brief
Match the pollutant, measurement height, source setting and period to the question being assessed. Use ratified annual data for trends and distinguish provisional live readings. Review the relevant background maps and emissions inventory edition before choosing model inputs.
For ecological receptors, identify the habitat and exposure pathway before selecting deposition or concentration methods. Keep health objectives, habitat criteria and WHO guidelines clearly identified.

Local requirements / Policy, guidance and validation
Wandsworth planning evidence: the current documents
Local Plan 2023: LP14
LP14 covers air quality, pollution and development impacts. Apply it with SI 1, at least Neutral development, exposure protection and construction/operational mitigation. Check the actual source and receptor relationships before selecting the assessment detail.
Local Validation Checklist: July 2026
Page 8 calls for an AQA for major/large-scale applications and those with potential air-quality impacts. It asks for both the proposal’s effects and existing pollution’s effects on new sensitive uses. Its old AQAP citation should be read with the current 2023–2028 plan.
Planning Obligations SPD 2025
The adopted SPD’s air-quality section addresses major AQAs and some minor schemes within or next to focus areas. It prioritises on-site solutions; an off-site contribution is an exceptional route requiring equivalent benefits, not a default substitute for design mitigation.
Older air-quality flowchart
The July 2020 guidance remains useful for organising construction and operational questions. Cross-check its policy and method references against LP14, the July 2026 checklist and the adopted 2023 London Neutral/Positive guidance.
Keep the assessment documents distinct
The impact assessment considers pollution and exposure. Air Quality Neutral compares development emissions with the applicable benchmarks. Air Quality Positive records opportunities to improve air quality through design. A construction dust assessment and management plan address the works themselves.
02 / Practical approach
Connect mitigation to delivery
Identify each measure, the drawing or specification it relies on, and the stage at which it needs to be in place. A construction dust plan should connect work activities with controls and inspections.
Operational measures should remain consistent with the energy and ventilation design. This gives the planning team a clear evidence trail when responding to conditions or design changes.
Illustrative project brief
A major application includes a dust-management plan and an evolving energy strategy. A mitigation schedule can identify the commitments that belong in each document and keep later revisions consistent.

Answer five questions to organise the assessment brief. Choose “Not sure yet” where information is missing; those points remain visible in your results.
Answers stay in this page. The planner organises evidence; it does not certify compliance or decide planning requirements.
04 / A clear assessment package
From the brief to the planning evidence
01 / Scope
Define the question
Bring together the local requirement, proposal, sources and receptors. Identify missing information before detailed work begins.
02 / Assess
Use consistent inputs
Align the baseline, traffic, plant and programme. Explain assumptions and compare relevant scenarios.
03 / Respond
Connect findings to design
Record mitigation and the drawings or specifications it relies on. Review material changes as the project develops.
Our London Neutral and Positive evidence planner helps organise the wider policy workstreams. For construction, use the London assessment and monitoring guidance alongside the site-specific brief.
Where extract, fan noise or sensitive neighbours are involved, coordinate the noise assessment and odour assessment with the same plans. The main air quality service page explains the broader assessment and monitoring services.
On the horizon / Status checked 19 October 2026
What is changing in Wandsworth?
The Local Plan partial review was adopted on 4 March 2026. It changed specified housing policies, not LP14. The AQAP remains the 2023–2028 plan, with revised measures linked by the council. Keep changes to monitoring equipment and new annual reports under review.
Council update and policy status
At regional and national level, track adopted guidance separately from consultations. Use the London air quality hub and main air quality guide for the wider framework, then check the edition relevant to the application date.

Local project questions
Wandsworth air quality questions
Which validation checklist is current?
The council’s application gateway links the July 2026 checklist. Its air-quality entry is on page 8 and includes major schemes and other proposals with potential impacts.
Did the 2026 partial review replace LP14?
No. The adopted partial review changed specified housing policies. LP14 remains part of the 2023 plan framework.
Why is there a gap in the Putney chart?
Table D reports insufficient valid annual data for 2022 and 2023. Joining those years would suggest evidence that is not available.
Is Putney’s 2024 value a complete-year measurement?
Its full-year capture was 68%. The council annualised the reported mean. That qualification matters when comparing years and selecting a model-verification dataset.
Are diffusion tubes and fine particles covered?
Yes. The report describes 55 non-automatic sites, separate PM₁₀ results and indicative PM₂.₅ sensor evidence. Check the pollutant and instrument type before using a result.
Can an off-site payment replace on-site mitigation?
The adopted SPD treats off-site measures as exceptional where suitable on-site provision is not feasible and equivalent benefits can be demonstrated.
Does the council’s WHO ambition change the legal objective?
No. The action plan’s health-based targets and national objectives have different purposes. State which benchmark, averaging period and date each comparison uses.
Should heliport or river activity be assessed everywhere?
No. Include those sources where proximity, operations and the exposure pathway make them relevant to the actual site. A borough location alone does not establish a material impact.
