Air Quality Assessment Norwich
Chartered environmental consultants providing air quality, dust and odour assessments across Norwich and Norfolk.
Environmental Consultants in Norwich
Norwich is Norfolk's regional capital and one of the most complete medieval cities in England, with a historic core that places real constraints on road capacity and traffic management. The city is also home to a dynamic modern economy anchored by the University of East Anglia, a rapidly expanding Norwich Research Park and a significant food and drink manufacturing sector. This combination of a constrained historic street network, significant commuter flows and a thriving food economy creates a nuanced air quality picture that developers and planning consultants need to navigate carefully.
Norwich City Council has declared Air Quality Management Areas covering the inner ring road and major radial corridors including the A140 Aylsham Road, the A11 Newmarket Road and the A1074 Earlham Road. These are routes where traffic volumes and junction congestion generate nitrogen dioxide concentrations that persistently breach national objectives. Major regeneration projects — most notably the long-planned transformation of the Anglia Square site in the north of the city centre — bring significant new residential and commercial uses into close proximity with these pollution hotspots, requiring detailed assessment and careful mitigation design.
Air Dust Odour provides air quality assessments, construction dust management plans and odour impact assessments for developers, architects and planning consultants working across Norwich and the wider Norfolk area. Our Chartered Environmentalists and MIAQM members are well versed in the requirements of Norwich City Council and the Broadland and South Norfolk councils, delivering clear and technically robust reports that help planning applications succeed.

Frequently Asked Questions
Do I need an air quality assessment in Norwich?
Norwich City Council has declared Air Quality Management Areas covering the inner ring road and key junctions on the A140, A11 and A1074 corridors, where nitrogen dioxide from road traffic exceeds national objectives. Planning applications for residential, commercial or mixed-use developments within or near these AQMAs will almost always require an air quality assessment. Major regeneration schemes such as Anglia Square and the broader City Centre Area Action Plan area are subject to particular scrutiny, as new sensitive receptors are being introduced close to existing pollution sources.
What are the main air quality issues in Norwich?
Norwich's air quality challenges are concentrated on its inner ring road and the radial routes feeding into the city, particularly the A140 from the north, the A11 from the south-west and the A1074 Earlham Road. Heavy traffic volumes, bus movements and the constrained urban road network generate elevated nitrogen dioxide levels at key junctions. The city's historic street layout limits road capacity improvements, making demand management and development design the primary levers for air quality improvement.
How much does an air quality assessment cost in Norwich?
Costs depend on the type and complexity of assessment required. A screening assessment typically starts from around £500, a detailed air quality assessment with dispersion modelling from around £1,500, and a kitchen odour assessment following EMAQ+ methodology from around £800. The specific requirements of Norwich City Council, the location of the site relative to declared AQMAs and the scale of the proposed development all influence the final fee.

Do I need a dust assessment for a construction project in Norwich?
Yes. Norwich City Council expects construction dust to be managed on all but the most minor developments, and most applications involving demolition, excavation or construction activity near occupied properties will require a dust risk assessment and, for larger schemes, a Construction Environmental Management Plan. The regeneration of the Anglia Square site — a major brownfield development in a residential area — is a good example of a project where robust dust management planning is essential. We prepare assessments in accordance with IAQM guidance.
We are opening a food business in Norwich — do we need an odour assessment?
Yes. Norwich has a thriving food and drink economy, with restaurants, cafes and takeaways concentrated in the city centre, the Norwich Lanes, Golden Triangle and surrounding neighbourhoods. New or significantly altered commercial kitchen operations will typically require an odour impact assessment as part of the planning application. We prepare assessments in accordance with EMAQ+ guidance and can provide advice on appropriate extraction and filtration equipment to meet Norwich City Council's requirements.
