QUALITY AIR ASSESSMENTS LTD

What QUALITY AIR ASSESSMENTS LTD does

Quality Air Assessments Ltd is a UK-based air quality consulting firm founded in 2014 by Directors Bob Thomas (Chartered Scientist, CSci) and Alison Thomas. The firm delivers ambient air quality consulting, dispersion modelling, monitoring, and assessment services for development projects across England, Scotland, Wales and Northern Ireland from its registered address in Burnham-on-Sea, Somerset. Its service portfolio spans eight core offerings: air quality assessment, dust assessment, odour assessment, planning application support, air quality modelling (using ADMS-Roads and ADMS 6 dispersion software), air quality monitoring (NO2 diffusion tubes, PM10, dust deposition), environmental permit support, and Local Air Quality Management (LAQM) support for local authorities.

The company's technology stack centers on regulatory-grade atmospheric dispersion modelling using ADMS-Roads (for road traffic emissions) and ADMS 6 (for point sources including decentralised energy, biomass/CHP, industrial sources and odour), both approved by UK regulators including the Environment Agency, Scottish EPA, Natural Resources Wales and the Northern Ireland Environment Agency. Methodology follows IAQM guidance for dust and odour assessments and DMRB for road scheme impacts, with GIS integration used for emissions source placement and graphical model outputs.

The business operates as a traditional professional services consultancy with a sales-led, direct-engagement go-to-market model. Customers (developers, planners, architects, local authorities) request free no-obligation quotes via phone or email, after which fixed-fee quotations are issued with no unexpected costs. Revenue is generated entirely from per-project professional services fees across six horizontal customer segments: residential, commercial, industrial, minerals and waste, road schemes, and local authorities. The firm has no external funding, operates with a headcount of 1-10 (effectively the two directors), and has remained founder-controlled since inception.

Core offering

Air Quality Assessments Ltd is a UK-based air quality consultancy providing ambient air quality assessments, dust and odour assessments, dispersion modelling, monitoring, and planning/environmental permit application support. The firm works directly with developers, planners and architects on residential, commercial, industrial, minerals and waste, and road scheme projects to support planning and permitting compliance. Services are delivered as fixed-fee consulting engagements, leveraging regulatory-approved ADMS-Roads and ADMS 6 dispersion modelling tools.

Product overview

QUALITY AIR ASSESSMENTS LTD is a UK-based air quality consulting firm offering a suite of assessment and advisory services. The company operates as a unified consulting service rather than a software platform, providing eight distinct but complementary service offerings: Air Quality Assessment (core offering), Dust Assessment, Odour Assessment, Planning Application Support, Air Quality Modelling (using ADMS-Roads and ADMS 6 software), Air Quality Monitoring, Environmental Permit Support, and Local Air Quality Management (LAQM). These services work together to help developers, planners, and architects navigate the planning and permitting system, from initial screening assessments through to detailed Environmental Statements and permit applications.
