Air Quality Assessment Hemel Hempstead
Chartered environmental consultants providing air quality, dust and odour assessments across Hemel Hempstead and Dacorum.
Environmental Consultants in Hemel Hempstead
Hemel Hempstead is one of the UK's original post-war New Towns and the principal settlement in Dacorum Borough. Its strategic location at the M1/M25 junction — Junction 8, where two of England's busiest motorways converge — makes it a major logistics hub, home to Maylands Industrial Estate, one of the largest business parks in the South East. This combination of intense motorway traffic and large-scale distribution activity creates complex air quality challenges for development across the town and borough.
Dacorum Borough Council has declared Air Quality Management Areas along the M1 and A41 corridors, where nitrogen dioxide concentrations exceed national objectives. Significant housing growth is planned under Dacorum's Local Plan, with substantial new residential development expected across the borough. Planning applications for sites near the AQMA or the motorway network require careful air quality assessment, and the council expects applicants to demonstrate that future residents will not be exposed to unacceptable air quality.
Air Dust Odour provides air quality assessments, dust management plans and odour impact assessments across Hemel Hempstead and Dacorum Borough. As Chartered Environmentalists and MIAQM members, we prepare assessments to the standard required by Dacorum Borough Council and routinely work with traffic data from the M1/M25 corridor.

Frequently Asked Questions
Do I need an air quality assessment in Hemel Hempstead?
Dacorum Borough Council has declared Air Quality Management Areas along the M1 and A41 corridors where nitrogen dioxide objectives are exceeded. Planning applications for residential, commercial or mixed-use development in or near an AQMA will typically require an air quality assessment. The council also expects assessment for developments that generate significant additional traffic or introduce new sensitive receptors near the motorway corridors.
What are the main air quality issues in Hemel Hempstead?
Hemel Hempstead's air quality is dominated by the M1/M25 junction at Junction 8, one of the most heavily trafficked motorway interchanges in England. Elevated nitrogen dioxide concentrations affect properties along the M1 and A41 corridors. The substantial logistics and distribution operations at Maylands Industrial Estate also contribute to HGV movements and associated air quality impacts across the town's road network.
How much does an air quality assessment cost in Hemel Hempstead?
Costs depend on the type and complexity of assessment required. Screening assessments typically start from around £500, detailed air quality assessments with dispersion modelling from around £1,500, and kitchen odour assessments from around £800. Assessments for sites near the M1/M25 AQMA may require additional traffic data. Contact us for a free tailored quote.
Do I need a dust assessment for construction in Hemel Hempstead?
Yes. Dacorum Borough Council expects a Construction Environmental Management Plan (CEMP) or dust risk assessment for most developments involving demolition, excavation or construction near sensitive receptors. Given the significant housing growth planned under the Local Plan, dust assessment is increasingly required for new residential schemes. We prepare CEMPs in accordance with IAQM guidance.
We are opening a food business in Hemel Hempstead — do we need an odour assessment?
Yes, most new or significantly altered food premises in Hemel Hempstead will require an odour impact assessment as part of the planning application. This is especially relevant for units at Maylands Industrial Estate or in the town centre. We prepare assessments in accordance with EMAQ+ guidance and can advise on appropriate extraction and filtration systems.
