Air Quality Modelling | FreshBreeze

Air quality modelling predicts how pollutants from a development will disperse and affect the surrounding area the technical evidence planning officers and regulators rely on. At FreshBreeze Environmental, we provide air quality modelling for developers, businesses and consultants across London, Manchester, Birmingham and the wider UK. Using industry standard dispersion models and following IAQM and DEFRA guidance, we produce clear, defensible reports that support planning applications and environmental permits.

What is air quality modelling?

Air quality modelling uses specialist software to predict pollutant concentrations at specific locations, based on emission sources such as road traffic and industrial plant. It estimates how pollutants like nitrogen dioxide (NO2) and particulate matter (PM10 and PM2.5) will spread and where they’ll settle, then compares those levels against national air quality objectives. Modelling is used when a simple screening assessment isn’t enough to show whether a development is acceptable.

When do you need air quality modelling?

Modelling is typically required for:

• New residential or commercial developments in densely populated areas
• Sites near sensitive receptors such as schools, hospitals or care homes
• Industrial operations needing an environmental permit application
• Developments likely to generate significant additional traffic or emissions
• Sites within or near an Air Quality Management Area (AQMA)

If you’re unsure whether your project needs modelling, we can advise before you commit to a full assessment.

Our air quality modelling services

Dispersion modelling

Using models such as ADMS-Roads, we assess how emissions disperse in the surrounding environment and predict pollutant concentrations at nearby homes and other sensitive receptors. This is the core of most air quality assessments for planning.

Traffic emission modelling

We quantify how vehicle emissions affect local air quality, building emission inventories from traffic data and testing different scenarios. Where impacts are identified, we recommend mitigation to reduce traffic related pollution.

Indoor air quality modelling

For occupied buildings, we assess ventilation effectiveness and identify indoor pollutant sources, helping you design healthier internal environments that meet relevant standards.

How our modelling process works

Step 1 — Initial consultation

We discuss your project, confirm what the planning authority requires, and agree the scope of modelling needed.

Step 2 — Data collection

We gather baseline air quality data, traffic inputs and details of emission sources, and identify the sensitive receptors around your site.

Step 3 — Technical modelling

We run the dispersion model to predict pollutant concentrations, test scenarios where relevant, and develop mitigation if the results call for it.

Step 4 — Reporting

You receive a clear report setting out our findings, how they compare against air quality objectives, and practical recommendations ready to submit with your application.

Costs and timeframes

The cost of air quality modelling depends on the complexity of your project. Basic modelling can usually be completed within two to four weeks, while more comprehensive assessments take four to eight weeks, often depending on how quickly traffic data is available.

Frequently asked questions

Do I need air quality modelling for my project?
If your development is near busy roads, includes significant emission sources, or sits in or near an Air Quality Management Area, modelling is often required to support your planning application. A quick screening check confirms whether it’s needed.

How long does air quality modelling take?
Most modelling projects take two to four weeks. More complex assessments, or those waiting on traffic data, can take four to eight weeks.

What software do you use for air quality modelling?
We use industry standard dispersion models such as ADMS-Roads, chosen to suit your site and the pollutants of concern, so the results are accepted by local planning authorities.

How much does air quality modelling cost?
Cost varies with the size and complexity of the scheme. Basic modelling is the most affordable option, while detailed assessments cost more. Contact us for a fixed quote for your project.
