Summary of the contracting process

The Defence Science and Technology Laboratory procured works to replace and/or upgrade mechanical and electrical building infrastructure, including associated assets and systems. The requirement is classified as repair and maintenance services for building installations (CPV 50700000), although its main category is works. Delivery is at the laboratory’s site in Porton Down, Salisbury. The scope concerns building infrastructure rather than standalone equipment supply, so it is relevant to contractors able to undertake integrated mechanical and electrical replacement and upgrade works in an operational science and technology environment. The buyer is the Defence Science and Technology Laboratory, which uses its Porton Down premises for this requirement.

The procurement is complete and was awarded through a selective call-off from a framework agreement. The tender deadline was 4 May 2026 at 4pm. The contract was awarded to NG Bailey Ltd on 26 June 2026 for £15,312,571.07 including the stated GBP currency. The contract period runs from 15 June 2026 to 14 June 2029. The published evaluation basis is not described beyond the framework call-off route. The opportunity was treated as a single requirement, with no separate lots identified. The buyer recorded the procurement as unsuitable for small and medium-sized enterprises and voluntary, community or social enterprises.

This award demonstrates substantial, multi-year demand from the Defence Science and Technology Laboratory for building infrastructure mechanical and electrical replacement and upgrade works at Porton Down. A future competitor would need to deliver coordinated mechanical and electrical construction services, manage replacement and upgrade programmes across building assets and systems, and operate reliably in a defence science and technology setting. The successful supplier was a large business, indicating that the requirement favoured organisations with significant delivery capacity, established project management, and the resources to handle complex building infrastructure works. Firms considering similar work for this buyer should be able to demonstrate relevant building-services experience, dependable site delivery, and the capacity to perform through a framework call-off process.
