Air Quality Assessment Hertford
Chartered environmental consultants providing air quality, dust and odour assessments across Hertford and East Hertfordshire District.
Environmental Consultants in Hertford
Hertford is Hertfordshire's county town, situated at the confluence of the rivers Lea, Beane, Mimram and Rib, and it occupies a strategically important position at the intersection of the A10 and A414 road corridors. These two routes together carry substantial volumes of HGV and commuter traffic — the A10 serving as the primary trunk road between London and Cambridge, and the A414 providing the key east-west link across the county. This traffic loading has contributed to elevated nitrogen dioxide concentrations in Hertford town centre and at Ware, prompting East Hertfordshire District Council to declare Air Quality Management Areas along both corridors. Hoddesdon, to the south, also experiences significant air quality pressures from the A10 and associated local road network.
Hertford sits at the southern end of the London-Stansted-Cambridge Corridor, one of the government's priority growth areas, and the district is subject to substantial housing and employment growth in its local plan. Planned allocations around the A10 and M11 corridor, including major sites near Bishop's Stortford and Sawbridgeworth, as well as significant urban extensions to Hertford and Ware themselves, will generate material increases in traffic on already pressured road corridors. The cumulative air quality effects of this growth — both on existing AQMAs and on undesignated road links — is a significant consideration for planning authorities, developers and environmental consultants working in the district.
Air Dust Odour provides air quality assessments, dust management plans and odour impact assessments for planning applications across Hertford, Ware, Hoddesdon, Bishop's Stortford and the wider East Hertfordshire District. Our Chartered Environmentalists and MIAQM members understand the requirements of East Hertfordshire District Council and prepare technically robust, clearly presented reports suitable for planning submissions of all scales. From a single dwelling close to the A10 corridor through to a large strategic housing allocation requiring Environmental Impact Assessment, we have the expertise and experience to support your project from inception to determination.

Our Services in Hertford
Air Quality Assessment
Planning-stage air quality assessments for residential, commercial and mixed-use developments in Hertford and East Hertfordshire. We assess impacts from the A10, A414 and associated local road network in line with IAQM guidance and East Hertfordshire District Council requirements, from screening assessments through to full EIA-level dispersion modelling.
Learn more →Dust Assessment & CEMP
Construction dust risk assessments and Construction Environmental Management Plans for demolition, excavation and construction projects across Hertford and the wider district. We evaluate risks from all phases of development, with particular attention to sensitive riverside and residential locations, and specify proportionate mitigation measures.
Learn more →Kitchen Odour Assessment
Odour impact assessments for restaurants, cafés, takeaways and commercial kitchens across Hertford and East Hertfordshire, prepared to the EMAQ+ methodology. We advise on extraction and abatement system requirements to support planning applications for new and altered food premises in town centre and residential-edge locations.
Learn more →Industrial Odour Assessment
Odour assessments for industrial, agricultural and waste management operations across East Hertfordshire, prepared in accordance with IAQM and Environment Agency guidance. We characterise emission sources, model dispersion and assess potential impacts on sensitive receptors to support planning and environmental permit applications.

Frequently Asked Questions
Do I need an air quality assessment in Hertford?
East Hertfordshire District Council has declared an Air Quality Management Area covering the A10 and A414 corridors and parts of Hertford town centre, where nitrogen dioxide concentrations from road traffic have historically exceeded national air quality objectives. Planning applications for residential, commercial or mixed-use development within or close to these corridors are expected to be supported by an air quality assessment, and the council's environmental health team scrutinises air quality evidence carefully given the district's position within the high-growth London-Stansted-Cambridge corridor. The scale of housing growth planned around Hertford, Ware and Hoddesdon means that cumulative air quality effects are an increasingly prominent consideration.
How does the A10 affect air quality assessments in Hertford and Ware?
The A10 is the principal north-south trunk road through East Hertfordshire, carrying a high volume of HGV and commuter traffic between London and Cambridge. It is the dominant source of elevated nitrogen dioxide concentrations along much of its route through the district, and the AQMA declarations in both Hertford and Ware reflect this. Developments proposed within approximately 200 metres of the A10 corridor are routinely screened in for detailed air quality assessment, with dispersion modelling needed to evaluate pollutant concentrations at sensitive receptors. The planned growth sites along the A10 corridor will require comprehensive cumulative air quality assessment.
Does growth along the London-Stansted-Cambridge corridor affect air quality requirements?
Yes. Hertford sits within the London-Stansted-Cambridge Corridor, one of the government's priority growth areas, and the scale of housing and employment growth planned in the district means that transport-related air quality is a significant planning consideration. Major housing allocations in East Hertfordshire require thorough traffic impact assessment and associated air quality modelling to demonstrate that development-generated traffic will not worsen conditions at existing AQMAs or create new areas of poor air quality. We provide strategic-level air quality assessment capable of addressing these cumulative and in-combination effects.
Do I need a dust assessment for construction in Hertford?
Construction dust risk assessments are required for most projects in Hertford and the wider East Hertfordshire District that involve significant demolition, excavation or earthworks, particularly for sites in proximity to the River Lea, residential areas or schools. The growth of new housing across the district means that many construction sites are in or near sensitive environments where dust control is a planning priority. We prepare assessments in line with IAQM guidance, identifying appropriate mitigation measures tailored to site conditions and the proximity of sensitive receptors.
We are opening a food business in Hertford — do we need an odour assessment?
Yes. New or materially altered commercial kitchen operations in Hertford and the wider district — including restaurants, cafés, takeaways and hot food counters — will typically require an odour impact assessment as part of the planning application where sensitive receptors such as residential properties are nearby. Hertford's compact town centre and the mixed-use character of many high street locations mean that odour from cooking operations is a recurring planning issue. We prepare kitchen odour assessments to the EMAQ+ methodology and advise on extraction and abatement system specifications.
