## Summary

The recent procurement process led by the Secretary of State for Health and Social Care through the UK Health Security Agency involved the provision of custom synthesis of DNA molecules at the UKHSA Porton Down facility in Salisbury, UK. This procurement, categorised under research laboratory services, followed a limited procurement method, specifically a direct award without prior publication of a call for competition. The tender was fully awarded on 6th June 2025 to Twist Bioscience, the sole supplier, due to unique intellectual property rights and supply needs specific to their capabilities. The procurement stage is complete, and the contract has been duly signed, underlining a targeted approach tailored to the agency's precise requirements.

This tender presents a unique opportunity for businesses specialising in biotechnology and the synthesis of oligonucleotides. Companies possessing significant intellectual property and specialised expertise in custom DNA molecule synthesis might align well with such procurement needs in the future. Expansion efforts could be focused on research and development capabilities and securing intellectual property that meets specialised requirements, enabling them to engage in similar direct award contracts. While this particular contract was not open to competition due to its specific needs, understanding and positioning for niche scientific services could help businesses leverage comparable opportunities within the public sector.
