## Summary

The Department for Environment, Food and Rural Affairs commissioned a health impact assessment of severe and prolonged poor air-quality episodes in the UK. The work is intended to quantify the likely human welfare impacts of such episodes, replacing earlier Defra analysis with the latest epidemiological evidence and improved understanding of short-term exposure effects and how air-pollution episodes develop. This is a research and development and related consultancy service. The work covers the UK and is for Defra as the central government buyer. The requirement is suited to organisations combining air-quality expertise with public-health, epidemiological and quantitative assessment skills, particularly those able to translate evidence on exposure into estimates of human welfare impacts.

The procurement is complete and was awarded through a non-competitive Defra self-service direct award under a framework, using a selective below-threshold route. Air Quality Consultants Ltd was selected for the single lot. The award was made on 26 August 2026 and the contract was signed on that date. The contract runs from 7 September 2026 to 18 December 2026. Its value is £63,037.50 excluding VAT, or £75,645 including VAT. The resulting contract is active. The process was not competitive, so the outcome reflects a direct framework award rather than an open competition. The requirement was evaluated and awarded as a research and consultancy service for the specified health-impact assessment.

For a supplier assessing future work from Defra, this award demonstrates demand for specialist analysis at the intersection of air quality, epidemiology, public health and economics or welfare assessment. A credible competitor would need to understand short-term exposure to air pollution, severe and prolonged pollution episodes, and the epidemiological evidence linking exposure to health effects. It would also need the analytical capability to model or quantify human welfare impacts and present defensible results for a central-government policy audience. Experience updating established government analysis with newer evidence and methods would be relevant, as would the capacity to deliver a focused research consultancy assignment to a defined timetable. The awarded supplier’s profile also shows that an SME can undertake this type of specialist requirement.

## Notice

Defra Self-Service Direct Award. The Department for Environment, Food and Rural Affairs is seeking to commission a health impact assessment (HIA) to quantify the likely human welfare impacts associated with a severe and prolonged poor air quality episode. This work will supersede previous analysis commissioned by Defra, incorporating the latest epidemiological evidence and advances in understanding of short-term exposure effects and air pollution episode structure.
