Air Quality Assessments

Air Quality assessments consider emissions, receptors and planning impacts for proposed developments.

Scope and evidence

Built around planning, development and compliance decisions.

Use this page to understand when the service is usually needed, what evidence is reviewed and what information helps us quote accurately.

  • Planning and regulator context
  • Clear deliverables and next steps
  • Linked services considered early

The assessment should distinguish between construction dust, road-traffic emissions and operational sources. Each has different data needs, receptors and mitigation options.

01

When this service is used

Used where traffic, dust, combustion emissions or sensitive receptors may affect planning acceptability, construction controls or operational compliance.

Planning and project supportUsed where development could introduce or be exposed to traffic emissions, dust, combustion sources or other air-quality constraints.
Risk and programme controlScreening the likely pathway early helps avoid unnecessary modelling while ensuring sensitive receptors and material emission changes are properly assessed.
02

What the report normally includes

  • Planning and receptor context review
  • Assessment scope based on development type
  • Air quality constraints and mitigation commentary
  • Dust or emissions considerations where relevant
  • Planning-ready conclusions and recommendations
03

What we need from you

Providing the right information at the start helps us confirm the scope, quote accurately and avoid back-and-forth once the work is underway.

  • Site address and proposed use
  • Planning reference if available
  • Transport or traffic information if available
  • Site layout and access information
  • Any local authority comments received

Air-quality scope depends on what could change because of the development

What a robust scope should cover
  • Local air-quality context and nearby sensitive receptors
  • Construction dust and earthworks risk where relevant
  • Existing and proposed traffic or operational emission sources
  • Development layout, access and receptor locations
  • Need for detailed dispersion modelling or a proportionate screening assessment
  • Mitigation and monitoring recommendations where required
What the work should leave you with
  • A clear planning conclusion on likely air-quality effects
  • Proportionate construction-dust controls
  • Identification of material traffic or operational emission issues
  • Mitigation measures linked to the actual source and receptor
Why the detail mattersA proportionate assessment avoids both extremes: overlooking a material impact or commissioning detailed modelling where screening demonstrates it is unnecessary.

Useful to know before you enquire

Traffic data can drive the scopeDevelopment flows, vehicle mix and nearby road conditions help determine whether detailed road-traffic assessment is needed.
Construction and operation are separateDust during construction and emissions once occupied are normally considered through different assessment methods.
Sensitive receptors should be mapped earlyHomes, schools, care settings and other receptors can influence survey, modelling and mitigation decisions.
Local authority comments are usefulIf the planning or environmental-health team has requested a specific assessment, send the wording so the scope addresses it directly.
FAQ

Common questions

Does every development need dispersion modelling?

No. The first step is to understand the likely change in emissions and receptor context. Detailed modelling is used where the screening evidence indicates it is warranted.

Can you assess construction dust?

Yes. Construction dust and trackout risks can be assessed separately from operational air quality, with proportionate mitigation measures for the construction phase.

What information helps with a quote?

Site plans, development description, traffic information if available, nearby receptors and any planning or environmental-health comments are particularly useful.
