Summary of the contracting process

The Submarine Delivery Agency, based in Bristol, United Kingdom, is progressing into the planning stage with the procurement process for the supply and support of valves and their actuators intended for submarines and potentially the Royal Navy's surface fleet. This process falls under the defence and security industry category and forms a part of the legal framework governed by the Procurement Act 2023. A key date is set for future notices till 10 July 2026, and this contract, valued at £65 million (net), is expected to commence from 1 October 2027 through to 30 September 2029.

This procurement presents significant opportunities for businesses specialising in mechanical and electrical components for military vessels, particularly those with expertise in submarine and warship parts. Companies experienced in spares, repairs, and technical support for valves and actuators, encompassing diverse functions like safety, control, and pressure reduction, are well-suited to compete in this flexible competitive procedure. Suppliers with capabilities in producing both nuclear-fuelled submarine components and surface fleet equipment may find potential to expand their portfolio through collaboration with a central government public authority such as the Submarine Delivery Agency.
