Environmental Consultants in Portsmouth
Portsmouth is one of England's most densely populated cities and one of its most constrained, occupying Portsea Island with limited road access points and a road network that must serve both the city's residents and the operational requirements of the naval base and ferry port. Portsmouth City Council has declared Air Quality Management Areas covering the M275 motorway, the A2030 Eastern Road and key parts of the city, where the concentration of traffic on a small number of arterial routes has produced persistent nitrogen dioxide exceedances. Any development that adds measurably to traffic flows in these areas, or that places new residents or other sensitive receptors near them, will typically trigger the need for an air quality assessment.
The naval base and ferry port are defining features of Portsmouth's air quality environment. Portsmouth Continental Ferry Port handles substantial volumes of freight and passenger traffic, with ro-ro ferry and cruise ship movements generating shipping emissions that contribute to the air quality burden on Portsea Island. The Naval Base generates significant HGV and support vehicle traffic through the city centre and along the M275 corridor. These operational sources must be factored into assessments for development anywhere in the port and city centre area. Major regeneration schemes at Tipner and North Harbour, which together have the potential to deliver thousands of new homes and a significant quantum of commercial and leisure floorspace, will require detailed assessment of air quality conditions given their proximity to the M275 AQMA.
Air Dust Odour provides air quality assessments, construction dust risk assessments, CEMPs and odour impact assessments across Portsmouth and the wider Solent region. Our Chartered Environmentalists have experience of the specific demands of Portsmouth City Council and understand the layered air quality challenges that arise from the combination of traffic, naval, port and ferry operations in this unique island city.

Our Services in Portsmouth
Air Quality Assessment
Screening and detailed air quality assessments for residential, commercial and mixed-use developments across Portsmouth and Portsea Island. We have experience of M275 and A2030 AQMA assessments and of assessments for development near the ferry port and naval base corridors.
Learn more →Dust Assessment & CEMP
Construction dust risk assessments and Construction Environmental Management Plans for demolition, earthworks and construction projects across Portsmouth. The high residential density of Portsea Island means that sensitive receptors are rarely far from any construction site, making thorough dust risk assessment essential.
Learn more →Kitchen Odour Assessment
Odour impact assessments for restaurants, takeaways, cafes and commercial kitchens across Portsmouth and Southsea, prepared in accordance with EMAQ+ guidance. Portsmouth's vibrant food and drink scene means kitchen odour assessments are regularly required for new and expanding food premises.
Learn more →Odour Impact Assessment
Industrial and process odour assessments for port-related and industrial operations across the Solent, and for residential developments that must demonstrate acceptable exposure conditions near operational sources. We work to IAQM and Environment Agency guidance on odour assessment and management.

Frequently Asked Questions
Do I need an air quality assessment in Portsmouth?
Portsmouth City Council has declared Air Quality Management Areas covering the M275, the A2030 Eastern Road and parts of the city centre, where nitrogen dioxide concentrations have exceeded national objectives. As a densely populated island city with limited road capacity, Portsmouth is particularly sensitive to traffic-related air quality impacts and the council routinely requests assessment for developments that generate significant vehicle movements or are located near AQMA boundaries.
How do the naval base and ferry port affect air quality in Portsmouth?
Portsmouth Naval Base and the Continental Ferry Port together generate substantial HGV, support vehicle and shipping traffic through the city's constrained road network. Ferry and cruise ship emissions contribute to the local air quality burden on Portsea Island, and developments proposed near the port or naval base or along primary HGV routes will typically need to address these sources as part of a planning-stage air quality assessment.
How much does an air quality assessment cost in Portsmouth?
Fees depend on the type and complexity of the work 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. Given the complexity of Portsmouth's road network and the influence of port and naval operations, some assessments may require additional data collection or modelling.

Do I need a dust assessment for my construction project in Portsmouth?
Most construction projects in Portsmouth requiring planning permission will need a construction dust risk assessment and, for larger schemes, a full Construction Environmental Management Plan. The densely built-up nature of Portsea Island means that construction sites are frequently in close proximity to residential properties and other sensitive receptors, making robust dust mitigation particularly important. We prepare assessments in line with IAQM guidance and to the specific requirements of Portsmouth City Council.
What are the air quality requirements for the Tipner and North Harbour regeneration?
The Tipner and North Harbour regeneration areas represent some of the most significant development opportunities in Portsmouth, with proposals for thousands of new homes, commercial space and transport infrastructure. These schemes require detailed air quality assessments that address proximity to the M275 AQMA, potential for cumulative traffic impacts on the city's constrained road network, and the need to demonstrate acceptable air quality conditions for future residents. We have experience preparing assessments for major mixed-use regeneration schemes in comparable settings.
