Summary of the contracting process

The Ministry of Defence, a central government public authority located in Portsmouth, United Kingdom, is overseeing the procurement process for the contract titled "AESAS 2026 - Provision of Aircraft Engineering Support and Airfield Services at Royal Naval Air Stations Yeovilton and Culdrose". This involves aircraft maintenance services in the defence and security sector. The process had reached the award stage on 2nd April 2026, with Serco Limited selected as the supplier for a 1 + 1 year contract valued at approximately £14,879,505.20. The procurement was conducted through a direct award method due to the unique operational expertise Serco holds, deemed crucial for continuity and efficiency in ongoing operations at these air stations.

This tender represents substantial growth opportunities primarily for large-scale enterprises experienced in defence services, particularly those specialising in helicopter repair and maintenance. Although Serco Limited was chosen for its established expertise in this context, related businesses could aim to build similar competencies and align themselves with the intricate requirements of national defence contracts. Such enterprises could potentially compete in future tenders, especially if new contracts arise or extensions are required. Opportunities exist for companies that can offer innovative solutions and efficient operational models within the demanding constraints of technical and safety standards applicable in defence sectors.

Notice Title

714928467 - AESAS 2026 - Provision of Aircraft Engineering Support and Airfield Services at Royal Naval Air Stations Yeovilton and Culdrose

Notice Description

The Royal Navy, part of the UK Ministry of Defence, intends to award a 1 + 1 year contract to Serco for the Air Engineering Support and Airfield Services (AESAS). 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 7 of Schedule 5 of the Act. This justification applies because the AESAS contract concerns the supply of services by the existing supplier which are intended as an extension to existing services in circumstances where: a change in supplier would result in the contracting authority receiving services that are different from, or incompatible with, the existing services. Namely, a different supplier would lack Serco's (i) deeply embedded operational expertise and established relationships at Yeovilton and Culdrose, and (ii) suitably trained and experienced staff. And b. the difference or incompatibility would result in disproportionate technical difficulties in operation and/or maintenance. In particular, the difference in service provided by a different supplier would result in: i. unacceptable risks to performance and safety resulting from the need to rebuild critical trust and operational knowledge; ii. the contracting authority needing to invest additional resources in order to retrain staff, modify existing systems, and/or purchase additional equipment; iii. a risk to the continued readiness and support to MCT aircraft, which is critical to national defence; iv. significant adjustments to the Contractor's Quality Management System, resulting in operational inefficiencies and increased costs; v. disruption to coordination and maintenance of ground support and equipment provision at RNAS Yeovilton; and vi. increase in lead times in returning airframes to flying operations at RNAS Culdrose and reduction in overall numbers of available aircraft in the forward fleet.
