The cost of an air quality assessment in the UK depends on the size, location, complexity, and potential environmental impact of a proposed development. A straightforward assessment for a smaller scheme may require less data collection and modelling, while larger developments or projects in areas with existing air quality concerns may involve more detailed analysis.
Other factors can include traffic modelling, dispersion modelling, site surveys, construction-phase impacts, and mitigation requirements. When comparing consultant quotations, developers and project managers should look beyond the headline price and check what services, surveys, modelling, reporting, and revisions are included.
Local planning authority requirements can also influence the scope and cost. Choosing an experienced air quality consultancy can help ensure the assessment is proportionate, technically robust, and suitable for supporting a UK planning application.
