Introduction
An air quality report is often required to support UK planning applications where a proposed development could affect local air quality or introduce new exposure for future occupants. Planning authorities rely on air quality reports to make informed decisions and to ensure proposals comply with local and national policy.
This blog explains air quality report requirements for development, what planners expect to see, and how a well-prepared report can support planning approval.
What Is an Air Quality Report?
An air quality report is a planning-led technical document that assesses air quality impacts associated with a development proposal. It interprets existing conditions and predicted impacts in a way that is relevant to planning decisions.
An air quality report typically:
- Reviews existing air quality conditions
- Assesses development-related impacts
- Considers exposure for future occupants
- Recommends mitigation where appropriate
The emphasis is on policy compliance rather than routine monitoring or testing.
When Is an Air Quality Report Required?
Local planning authorities may request an air quality report where development:
- Is located near busy roads or transport corridors
- Increases traffic movements
- Introduces new residential or other sensitive uses
- Is within or close to an Air Quality Management Area
The requirement is usually confirmed during the planning process or at pre-application stage.
What Do Planners Expect in an Air Quality Report?
Site and Development Description
An air quality report should clearly describe:
- The site location and surroundings
- The scale and nature of the proposed development
- Relevant sources of air pollution
This context helps planners understand why the report is required.
Policy Context
Planners expect the report to reference:
- Relevant national planning policy
- Local authority air quality policies
- Any site-specific planning guidance
This demonstrates that the assessment aligns with policy expectations.
Assessment Methodology
A clear air quality report explains:
- The assessment approach used
- Any assumptions made
- Why the chosen methodology is appropriate
Transparency is essential for planning review.
Assessment of Impacts
The report assesses:
- Potential changes in air quality
- Impacts on future occupants and neighbours
- Whether effects are significant in planning terms
The focus is on interpretation rather than raw data.
Mitigation Measures
Where necessary, the air quality report outlines:
- Practical mitigation measures
- Design responses to reduce impacts
- How mitigation supports acceptability
Mitigation should be proportionate and achievable.
How an Air Quality Report Supports Planning Approval
A well-prepared air quality report can:
- Reduce planning objections
- Address environmental health comments
- Avoid delays caused by further information requests
By clearly presenting conclusions, it helps decision-makers reach confident outcomes.
Keeping Reports Proportionate
Not all developments require the same level of detail. A proportionate air quality report:
- Focuses on planning relevance
- Avoids unnecessary assessment
- Provides clear conclusions
This benefits both applicants and local authorities.
Conclusion
An air quality report is a key planning document for developments where air quality is a material consideration. By meeting policy requirements and focusing on proportionate assessment, an air quality report can play a vital role in securing planning consent.
Early professional advice can help ensure the report is scoped correctly from the outset.
Frequently Asked Questions
Q1: Is an air quality report the same as air quality monitoring?
A1: No. Most air quality reports rely on existing data and assessment rather than new monitoring.
Q2: Who reviews an air quality report during planning?
A2: Planning officers and environmental health teams typically review air quality reports.
Q3: Can an air quality report be conditioned?
A3: Yes. Mitigation measures identified may be secured through planning conditions.
