Care Home Air Quality Assessment
Air quality assessments for care home and residential care planning applications. We assess NO2, PM2.5 and site suitability for vulnerable occupants — with practical mitigation recommendations that planning authorities accept.
Air Quality Assessment for the Most Sensitive of Receptors
Care homes, nursing homes and residential care facilities are among the most sensitive land uses that planning authorities consider. Their residents — typically elderly people and those with chronic health conditions — are the groups most at risk from elevated concentrations of nitrogen dioxide, fine particulate matter and other traffic-related pollutants. Local planning authorities know this, and they scrutinise air quality for these applications accordingly.
A care home air quality assessment must demonstrate not just that the site meets annual average objectives, but that concentrations are appropriate for continuous occupation by vulnerable people. Where background concentrations are elevated, or where the site is close to a busy road or industrial source, the assessment needs to address both the quantitative evidence and the qualitative question of whether the location is truly suitable for the proposed use.
At Air Dust Odour, Malcolm Pounder CEnv MIAQM leads all assessments for care and healthcare uses personally. We provide technically rigorous, clearly presented reports that address the specific concerns planning officers and public health consultees raise for this type of development — and we identify practical mitigation measures where the evidence base requires them.
Our Care Home Air Quality Services
From desktop screening to detailed modelling for complex sites, we provide the right level of assessment for your planning application.
Air Quality Screening Assessment
A desktop review of DEFRA background data, local AQMA status and proximity to roads to establish baseline air quality at the proposed site. Compared against UK objectives and, where relevant, WHO Air Quality Guidelines for sensitive uses. Provides a clear statement on whether the site is likely to be acceptable for care home use without the need for further detailed assessment.
Detailed Dispersion Modelling Assessment
For sites close to major roads, within AQMAs or in areas with elevated background concentrations, a detailed assessment using ADMS-Roads or similar dispersion modelling software. Predicts actual NO2 and PM2.5/PM10 concentrations at the proposed building facade and outdoor amenity areas, calibrated against local monitoring data where available, and assessed against the full suite of relevant objectives and guidelines.
Mitigation Strategy
Where air quality concerns are identified, we provide a clear, practical mitigation strategy covering building layout and orientation, ventilation system specification (including filtration requirements), outdoor amenity space positioning, green infrastructure, and air quality monitoring conditions. All recommendations are grounded in what planning authorities expect to see for sensitive uses and what is deliverable within a care home design and construction programme.
Pre-Application & Stakeholder Support
Pre-application advice on site suitability, air quality scope and assessment methodology before you invest in a full planning application. We can prepare scoping letters, attend pre-application meetings with the LPA, and liaise with local authority environmental health officers and public health consultees on your behalf. For contentious sites, early engagement saves significant time and cost downstream.
Care & Healthcare Uses We Cover
We provide air quality assessments for the full range of residential care and healthcare land uses, from small specialist care homes to large Extra Care housing schemes and NHS facilities.
Our clients include specialist care home developers and operators, healthcare property investors, NHS trusts, planning consultants working on healthcare projects, and national housebuilders developing Extra Care schemes.
- Residential care homes
- Nursing homes

Frequently Asked Questions
Why do care home planning applications need an air quality assessment?
Care homes and residential care facilities are classified as particularly sensitive receptors for air quality purposes because their residents — typically elderly people and those with underlying health conditions — are among the groups most vulnerable to air pollution. Local planning authorities apply greater scrutiny to air quality assessments for these uses, particularly where the proposed site is close to a busy road, within an Air Quality Management Area, or in an area where background NO2 or PM2.5 concentrations are elevated.
What pollutants are assessed for care home applications?
The primary pollutants are nitrogen dioxide (NO2) and particulate matter (PM10 and PM2.5). Background concentrations are sourced from DEFRA’s PCM model and compared against UK air quality objectives (NO2 40 µg/m³ annual mean) and WHO Air Quality Guidelines. For sites close to major roads, we also assess the road traffic contribution at the building facade using dispersion modelling. Site-specific sources such as nearby industrial processes are also considered where relevant.
What mitigation can be recommended if air quality is poor at a care home site?
Mitigation measures can include building orientation and layout to maximise distance between habitable rooms and emission sources, enhanced ventilation systems with high-efficiency filtration, green infrastructure and planting buffers, outdoor amenity space positioned away from the primary emission source, and air quality monitoring conditions. We provide practical, proportionate recommendations and advise honestly on whether a site is fundamentally suitable for the proposed use — a view that planning authorities will form regardless, so it is better to understand it early.
Does a care home need an air quality assessment if it is not in an AQMA?
Yes — the absence of an AQMA does not mean that air quality is acceptable at a specific site. AQMAs are declared where annual air quality objectives are being breached, but concentrations can be approaching the objective even outside a designated area. For a sensitive use such as a care home, many local authorities will require an assessment regardless of AQMA status. The relevant question is whether the site-specific concentrations are appropriate for the intended use and the health of the people who will live there.
How long does a care home air quality assessment take?
A care home air quality screening assessment using desktop data can typically be completed within 5 to 10 working days. Where detailed dispersion modelling is required — for example, sites close to major roads or in areas with elevated background concentrations — timescales may be 3 to 4 weeks. We discuss programme requirements at the outset and work to your planning application timetable.
