Construction Begins on £50 Million Army Infrastructure Programme at Tidworth and Warminster

Homeland July 28, 2026

Two major construction projects on Salisbury Plain signal the continued pace of delivery under the Defence Estate Optimisation Army Programme – and the sustained infrastructure pipeline it is generating for the defence construction supply chain.

Construction has begun on new and improved military facilities at Assaye Barracks, Tidworth and Battlesbury Barracks, Warminster, representing a combined investment of approximately £50 million under the Ministry of Defence’s Defence Estate Optimisation Portfolio. The projects, delivered by Aspire Defence on behalf of the Defence Infrastructure Organisation, will modernise accommodation and operational infrastructure for three Army units as part of the wider rebasing and estate consolidation programme running across Salisbury Plain.

At Assaye Barracks in Tidworth, a £13 million investment will deliver a new Regimental Headquarters for 1 Medical Regiment, following the demolition of legacy buildings on the site. The new HQ will free up existing office and working space for The Royal Lancers, who are relocating to Tidworth from Catterick in 2027 and will also benefit from newly completed storage facilities delivered ahead of their arrival. The sequencing of the two units’ requirements – with 1 Medical Regiment’s new build enabling the accommodation of The Royal Lancers without displacing existing capability – is a practical illustration of the estate optimisation logic running across the DEO programme, which is designed to consolidate the defence footprint while improving the quality of what remains.

At Battlesbury Barracks in Warminster, a £37 million programme is modernising facilities for 2nd Battalion The Royal Yorkshire Regiment, who have relocated from Chester. Main construction is scheduled to begin this summer and will deliver a new Officers’ Mess, modern Quartermaster facilities and a gym extension, with refurbishment of the Regimental Headquarters already completed. Both projects are expected to reach completion by early 2028.

Brigadier Grant Kerr, Head of Army Infrastructure Plans, described the construction start as another important step in delivering a modernised Army estate, linking investment in high-quality infrastructure directly to the day-to-day experience of service personnel and the operational capability that infrastructure underpins. DIO Programme Manager Barry Ray highlighted the breadth of the Battlesbury and Assaye programmes as part of a £50 million commitment under the DEO Army Programme, while Aspire Defence Chief Executive Allan Thomson framed the groundbreaking as a milestone in enhancing the broader Project Allenby/Connaught estate across the Salisbury Plain garrison cluster.

The DEO programme’s wider purpose extends beyond improving individual facilities. By delivering more modern and sustainable infrastructure while releasing surplus land for alternative redevelopment, it is actively reshaping the defence estate’s footprint – reducing the built estate where operational need has changed while investing where it has grown. The Tidworth and Warminster projects sit within a Salisbury Plain investment programme that also includes the recently completed solar array at Larkhill Garrison and the 281 new service family homes at Imjin Barracks, giving the region one of the most active defence infrastructure pipelines currently running in the UK.

For the UK defence supply chain

The Defence Estate Optimisation Army Programme represents a long-running and geographically distributed source of construction and infrastructure opportunity for the supply chain. The Tidworth and Warminster projects join a growing list of active DEO sites across Salisbury Plain and beyond, with the programme’s dual mandate of new build delivery and surplus land release creating demand across a broad range of construction, engineering and facilities management disciplines. For businesses already working in defence construction or looking to enter the sector, DEO – delivered primarily through long-term partnering arrangements such as Project Allenby/Connaught – is one of the most consistent and visible pipelines in the current estate programme.
