## Summary

The Defence Science and Technology Laboratory (DSTL), part of the UK Ministry of Defence, has completed a procurement process using a limited negotiated procedure without prior publication for the provision and maintenance of a Continuous Emissions Monitoring System (CEMS). The awarded contract is valued at £221,156.45 and will span from 1st May 2025 to 30th April 2030. Located in Salisbury, England, the procurement falls under the services category of air pollution monitoring or measurement services and was awarded to Endress+Hauser Limited, operating as the supplier. The award was made official on 15th May 2025, with the tender procurement stage considered complete.

This tender presents significant business growth opportunities for companies specialised in air pollution monitoring and related services. However, the negotiated procurement method suggests the buyer requires specific technical expertise, which must align with the technical reasons cited under the relevant Public Contracts Regulations, potentially limiting opportunities for new market entrants. This contract suits large enterprises with established expertise in emissions monitoring and existing relationships in the defence sector, particularly those capable of providing comprehensive maintenance and support services to ensure compliance with environmental standards.
