Expert air quality, dust and odour assessments across Halifax and Calderdale. Our chartered professionals support planning applications throughout the borough.
Halifax is the principal town of Calderdale Metropolitan Borough and occupies a position deep in the Calder valley — a topographical setting that makes it one of the most challenging air quality environments in West Yorkshire. Calderdale Council has declared Air Quality Management Areas covering the A629, A58 and Halifax town centre, where nitrogen dioxide concentrations have persistently exceeded the annual mean objective. The valley’s steep sides and tendency towards temperature inversions under calm, stable conditions trap traffic emissions at low level, producing pollutant concentrations that are materially higher than comparable flat-terrain urban areas and that demand careful treatment in any air quality assessment.
Halifax has experienced a significant regeneration impetus in recent years, with the award-winning restoration of The Piece Hall acting as a catalyst for new commercial, residential and mixed-use development in and around the town centre. Mill conversion schemes are proliferating across the borough, from the upper Calder valley settlements of Hebden Bridge and Todmorden to the valley-floor towns of Sowerby Bridge and Elland. These projects — typically involving extensive demolition, earthworks and construction in tightly constrained urban settings — routinely require construction dust risk assessments and CEMPs to manage impacts on adjacent residential receptors throughout the build programme.
At Air Dust Odour, we work with developers, architects and planning consultants across Halifax and the wider Calderdale borough. Our Chartered Environmentalists have specific expertise in valley-topography air quality assessment and understand Calderdale Council’s approach to air quality policy and the requirements it places on planning applications. We produce technically robust, clearly written reports that satisfy planning officers and support the delivery of your project. We also provide noise and lighting assessments where these are required alongside air quality work.

Screening and detailed air quality assessments for residential, commercial and mixed-use developments across Calderdale. Our assessments follow IAQM guidance and are tailored to Calderdale Council’s requirements, incorporating valley-topography dispersion modelling where required to accurately predict pollutant concentrations at new receptors and demonstrate compliance with air quality objectives at proposed development sites within or near the borough’s AQMAs.
Dust risk assessments and Construction Environmental Management Plans for demolition, earthworks and construction across the borough. With Halifax’s dense stock of stone-built mill buildings undergoing conversion and the tight urban grain of most development sites, a robust dust assessment and CEMP are essential to managing impacts on adjacent residential properties and satisfying Calderdale Council’s planning conditions.
Odour impact assessments for industrial, food, waste and agricultural operations across Calderdale. We assess odour emissions and receptor exposure using IAQM guidance and, where required, quantitative dispersion modelling, accounting for the valley topography that can concentrate and transport odours in unexpected directions under drainage-wind conditions. We advise on appropriate abatement technology and odour management plan content to support planning applications.
Kitchen odour risk assessments following the EMAQ+ methodology for restaurants, takeaways, cafes and commercial kitchens across Halifax and Calderdale. The borough’s active food and hospitality sector, particularly in Halifax town centre and the visitor destinations of Hebden Bridge and Todmorden, means kitchen odour assessments are regularly required by Calderdale Council for new or expanded commercial catering operations.
We provide air quality, dust and odour assessment services across Calderdale and the surrounding West Yorkshire area.
If your development is within or adjacent to one of Calderdale Council's Air Quality Management Areas, or introduces new sensitive receptors near a busy road, an air quality assessment is very likely to be required. Calderdale's AQMAs cover the A629, A58 and Halifax town centre, where nitrogen dioxide concentrations have consistently exceeded the annual mean objective. Residential, commercial and mixed-use developments near these corridors will typically require a detailed air quality assessment as part of the planning submission.
Halifax sits in the Calder valley, one of the deepest and most confined river valleys in West Yorkshire, and this topography is the single most important factor shaping air quality across the borough. Under calm, stable conditions, cold air drains into the valley floor creating temperature inversions that trap traffic emissions at low level and drive nitrogen dioxide concentrations well above those seen in flat urban areas with comparable traffic volumes. Dispersion modelling for Halifax developments must account explicitly for these valley meteorological conditions, and Calderdale Council will scrutinise closely any assessment that uses generic flat-terrain meteorology without site-specific justification.
The successful regeneration of The Piece Hall has transformed Halifax town centre and stimulated a significant pipeline of new residential, commercial and mixed-use development in and around the AQMA. Developers bringing forward schemes in the town centre should expect Calderdale Council to require air quality assessments that address exposure of new occupants to existing pollution, the traffic generation impacts of the proposed development, and appropriate mitigation such as mechanical ventilation with filtration for residential units in the most polluted locations. The cumulative effect of multiple new schemes increasing traffic in a constrained valley-floor network is a material consideration for the authority.
Halifax and the wider Calderdale borough have an exceptionally dense legacy of stone-built textile mills, many of which are being converted to residential, commercial and mixed-use uses. These projects frequently involve extensive internal demolition, structural alteration and external works in tightly constrained urban settings where residential neighbours are often directly adjacent. Calderdale Council will routinely require a construction dust risk assessment and CEMP for mill conversion schemes to demonstrate that neighbouring properties will be protected from dust nuisance and that appropriate controls are in place throughout the build programme.
A screening assessment can typically be completed within 5 to 10 working days. Detailed assessments incorporating valley-topography dispersion modelling generally take 2 to 4 weeks, depending on project complexity and traffic data availability. Where baseline air quality monitoring is required, this can add 3 to 6 months to the programme. We are well versed in Calderdale Council’s requirements and can work to tight planning application deadlines where needed.
