Air quality assessment in Hammersmith and Fulham

Hammersmith · A4 and town-centre roads

Review junctions, queuing traffic, servicing and road-facing rooms. A sheltered rear intake can have different exposure from a frontage. Coordinate the assessment with ventilation, overheating and acoustic design.

Shepherd’s Bush · White City

Match the evidence to the road and receptor setting. Phased development can place existing neighbours and early occupants beside continuing construction. Record access routes, occupied phases and nearby schools or homes.

Fulham · Sands End and the river

Consider local traffic, energy plant, commercial kitchens and construction access. Check river activity where it creates a relevant source–receptor pathway. Assess each source using its location, emissions and operating pattern.

Old Oak · planning boundary

Parts of the wider Old Oak and Park Royal area fall within OPDC’s planning boundary. Confirm the application authority and applicable development plan before using the borough checklist. Check OPDC planning information.

Diffusion tubes · a discontinued network

The report says the council’s 56-site NO₂ tube network ceased in 2023 following data-quality concerns. It lists no council tube sites for 2024 or 2025. Historical tube tables should not be counted as a current network.

Particles and ozone · different questions

All six stations report PM₁₀ and PM₂.₅; five also monitor ozone. Reported 2025 PM₂.₅ means range from 8–10 µg/m³. Keep pollutant, averaging period and assessment criterion together when interpreting any result.

Sensors · additional local detail

The 60 installed Breathe London sensors measure NO₂ and PM₂.₅. Check calibration, capture and quality status before using sensor data for assessment or model verification. Instrument count does not mean every sensor has a complete annual series.

Background · representative evidence

Compare the urban-background station with the site setting and Defra data for the assessment year. Add relevant road or plant contributions without double-counting them. Provisional live readings describe recent conditions; use suitable ratified evidence for an annual baseline.

Hammersmith · road-facing homes

For a home or sensitive use near the A4 or town-centre junctions, map occupied façades, balconies and intake heights. Compare the road setting with HF5 rather than treating its annual mean as the concentration at every floor.

Useful project outputA receptor and intake schedule aligned with noise and overheating design.

White City · phased regeneration

Check whether early residents, schools or workplaces will be occupied during later demolition and construction. Keep construction dust, construction traffic, operational emissions and Air Quality Neutral calculations identifiable.

Useful project outputA phase-by-phase receptor plan, dust controls and shared assessment assumptions.

Fulham and Sands End · plant and servicing

For mixed-use schemes, kitchens or plant changes, establish fuel, duty cycle, flue position and nearby windows. Consider delivery movements and any credible riverside source; coordinate odour treatment with fan noise and access for maintenance.

Useful project outputA coordinated plant, extract and servicing schedule on the same layout.

Old Oak · authority and cumulative scope

Confirm whether the site falls within OPDC’s planning area. Agree relevant neighbouring schemes, affected roads and construction programmes before fixing the baseline. Review ecological pathways where emissions could affect designated habitats.

Useful project outputAn authority-specific brief and an agreed list of cumulative scenarios.

Planning practice · reported council activity

The 2025 ASR describes dust-risk review, air-quality dust management conditions and NRMM auditing. It reports 581 applications reviewed for air-quality impacts. Read the planning update, pp49–52.

Machinery · prepare for later phases

The ASR sets out a major-development condition pathway towards zero-exhaust-emission machinery: at least 50% of relevant 1–560 kW NRMM by January 2028 and all by January 2030. It also describes Stage V and exemption provisions. Check the actual decision notice and current council approach for the project. Read the published condition wording, p52.

Local Plan · emerging, not adopted

The 6 July 2026 Cabinet decision approved a Regulation 19 draft for consultation. The adopted-plan gateway still identifies the February 2018 plan. Check subsequent consultation, examination and adoption notices at submission. Regulation 19 decision.

Local air-quality action · current priorities

The council’s current gateway identifies the Air Quality Action Plan 2025–2030, adopted on 16 December 2024. Its priorities include building emissions, cleaner deliveries, monitoring and protection of vulnerable residents. Keep local health ambitions distinct from statutory objectives.
