## Summary

The Ministry of Defence (MOD), a central government public authority based in Portsmouth, UK, is overseeing the procurement process for the "Air Purification Maintenance - UKTN" contract. This contract involves the relocation and maintenance of air purification equipment and falls under the industry category of works, specifically targeting purification-plant repair and maintenance. The procurement process is in the award stage, with a direct award method applied. The contract, valued at a gross amount of £1.4 million, was awarded to CMS2. Key dates include the contract period commencing on 1 September 2025 until 1 February 2026, with the option to extend by up to two months until 31 March 2026. A standstill period is set to end on 8 September 2025.

This procurement opportunity offers significant business growth potential, particularly for companies specialising in technical and maintenance services for purification systems. The requirement for the Original Equipment Manufacturer (OEM), CMS2, suggests that other businesses with expertise in air purification technology, intellectual property rights, and technical specifications could find similar projects of interest. The limited competition due to technical and intellectual property restrictions underscores the opportunity for specialised firms to establish or reinforce their presence in essential government contracts, potentially leading to long-term partnerships and increased market visibility.

### Procurement Information

The Royal Navy, part of the UK Ministry of Defence, intends to award a 5 month contract with a value of PS1.4million to CMS2 for the Air Purification Equipment Maintenance. As a covered procurement, this procurement falls to be regulated under the provisions of the Procurement Act 2023. In the circumstances, the authority may award this public contract directly in accordance with section 41 of the Procurement Act 2023. The applicable direct award justification is that set out in paragraph 5 and 6 of Schedule 5 of the Act. This justification applies because the Air Purification contract concerns the supply of services where CMS2: a) Are the Original Equipment Manufacturer (OEM) for the equipment installed at HMS SULTAN and asserts a claim of intellectual property rights; they are the only organisation that hold the information required to define the written scheme of examination or to conduct the maintenance, and b) an absence of competition for technical reasons, only a particular supplier can supply the goods, services or works required c) There are no reasonable alternatives as a result of this. CMS2 and therefore are the only contractor able to determine the maintenance requirement (the written scheme of examination), and the maintenance specification, and are therefore the only company able to undertake for the maintenance.
