## Summary

The Environment Agency invites tenders for the "UK Hydrocarbons Monitoring Network 2025-2027" contract, focusing on air quality management services across the UK. This procurement process is currently in the award stage, with Ricardo-AEA Ltd selected as the supplier. The contract aims to manage networks of air pollution monitoring sites for measuring and assessing Benzene and volatile organic compounds. Significant dates include the signing date on 25th March 2025, and the networks consist of both automatic and non-automatic elements. This initiative was carried out under a limited procurement method, which involved awarding the contract without prior publication of a call for competition due to the specific technical requirements and the absence of alternative suppliers.

This tender offers substantial opportunities for businesses specializing in environmental monitoring and air quality management services. Companies with expertise in operating and maintaining pollution monitoring equipment, conducting data collection, and analysis are ideally suited to compete. Industries that leverage advanced technological solutions for air quality assessment can benefit from associating with long-term government contracts, promoting stability and growth. The continued evolution of monitoring technology and the commitment to aligning with the UK's changing pollution climate indicates ongoing opportunities for innovation and collaboration.

## Notice
