£82M infrastructure project completed at MOD Lyneham

Homeland January 29, 2026

The UK Government has confirmed a significant expansion of the Great British Energy solar programme, with new funding to deploy renewable energy systems across schools, NHS sites, and military facilities

The Defence Infrastructure Organisation (DIO) has announced the completion of an £82M infrastructure project at MOD Lyneham in Wiltshire, marking a significant upgrade to the UK’s technical training estate.

The project, delivered by main contractor Kier Construction Western & Wales in partnership with technical service provider Mott MacDonald, includes the construction of state-of-the-art training facilities and modern living accommodation. This development is a central component of Project CUBIT, which facilitates the relocation of the RAF No 4 School of Technical Training (4SoTT) from its previous base at MOD St Athan in South Wales. The transition ensures that the RAF’s ground engineering personnel have access to purpose-built infrastructure designed to support both Phase 2 and Phase 3 training requirements.

The newly delivered assets include three Single Living Accommodation (SLA) blocks providing a total of 168 bedspaces – comprising 96 beds for trainees and 72 for permanent staff and visiting personnel from other units. In addition to residential facilities, the site now features a dedicated technical building equipped with advanced classrooms, specialized laboratories, workshops, and administrative office spaces. This technical hub is designed to accommodate a high volume of specialist training, reflecting the Ministry of Defence’s (MOD) ongoing commitment to modernizing the learning environments for its technical cadres.

A notable feature of the MOD Lyneham project is the integration of a 2.5MVA solar farm and a comprehensive battery storage system. This renewable energy infrastructure is intended to provide the new facilities with a high degree of energy resilience and self-sufficiency, aligning with the MOD’s wider sustainability targets and its strategy to reduce operational carbon footprints across the defence estate. For businesses operating within the green energy and power management sectors, this demonstrates a growing requirement for sustainable utility solutions within major defence infrastructure tenders.

The project has also contributed to regional economic growth, creating the equivalent of 19 new jobs during the construction phase and providing upgrades to the MOD Lyneham Community Centre. While the main structural work is complete, the project is now entering a critical fit-out phase. This stage, which includes the installation of specialized training equipment and technical hardware, will continue through 2025 ahead of the facility’s scheduled opening in 2026. This timeline offers ongoing opportunities for sub-contractors and technology providers capable of delivering specialized engineering and educational tools. The successful delivery of these world-class facilities underscores the importance of long-term partnerships between the DIO and industry leaders in maintaining a robust and future-ready defence estate.
