## Summary

The procurement process, initiated by the Secretary of State for Health and Social Care acting through the UK Health Security Agency, involves the direct awarding of a contract to We Care 4 Air Limited for the supply of mercaptan gas analysers. These are intended for use in mobile ambient air monitoring trailers to measure mercaptan compounds. The contract is governed by the Procurement Act 2023 and was signed on April 2, 2026, with an end date of March 31, 2027. The procurement, classified under goods in the gas-analysis apparatus category, primarily serves the public health sector in the United Kingdom and is highly specific, warranted due to technical reasons which eliminate alternative suppliers.

The direct award offers significant opportunities for We Care 4 Air Limited, a small to medium-sized enterprise based in Dunmow, as it is uniquely positioned to supply equipment compatible with existing systems involving nitrogen gas generators. This tender highlights a specialised niche for businesses that can offer technologically advanced solutions in environmental monitoring. Such businesses that provide unique, compatible instrumentation aligning with existing public infrastructures can explore further public sector growth opportunities, notably within central government contracts needing bespoke technical capabilities.

## Notice

These analysers are to be employed in the mobile ambient air monitoring trailers to measure mercaptan compounds from a range of potential pollution sources where there are key evidence gaps to support the public health risk assessments. The Mercaptan gas analysers will increase the capabilities of monitoring trailers to measure mercaptans/ sulphur-containing compounds. Any other manufactures or alternative instrument will result in incompatibility with existing equipment (nitrogen gas generators), disproportionate technical difficulties in operation and maintenance, financial efforts to revalidate and recalibrate systems
