The Crown Commercial Service (CCS) has initiated the procurement process for a £120 billion construction framework intended to facilitate public sector building and engineering initiatives across the UK over an eight-year period. Running from January 2027 to January 2035, this extensive construction framework will function as a central procurement mechanism for a wide array of civil engineering, defence, and healthcare infrastructure initiatives. Administered by the commercial arm of the Cabinet Office, the arrangement will be accessible to central government departments, local authorities, and NHS bodies, alongside housing organisations, devolved administrations, charities, educational institutions, and emergency services.
This upcoming arrangement will replace and expand several existing systems by integrating traditional building works, specialist sectors, and infrastructure delivery into a single construction procurement structure. The programme is categorized into seven principal lots, with multiple sub-lots organized by project value, geographical region, sector, and specialist capability.
For public sector executives and NHS bodies, dedicated segments will directly address facility development and long-term capital plans. Lot 1 focuses on general building works and associated activity across regional and national tiers, supporting projects from under £5 million to major developments exceeding £250 million. Lot 2 covers civil engineering and broader infrastructure delivery, encompassing utilities, highways, demolition tasks, and wider regional projects. Lot 3 is allocated entirely to offsite construction and modular delivery formats, targeting essential public sectors including justice, education, defence, and healthcare infrastructure.
The reliance on offsite construction demonstrates government ambitions to improve productivity, accelerate project timelines, and lower carbon emissions across major public programmes. Furthermore, additional specialized lots are designated for targeted healthcare construction projects, nuclear capabilities, defence infrastructure, and international engineering works.
Frameworks of this scale are central to how public sector organisations secure works, providing authorities with certainty regarding pricing, capability, and schedule execution for long-term investment plans. The extensive duration of the agreement is expected to provide contractors, consultants, manufacturers, and specialist suppliers with substantial workflow opportunities. At the same time, the scope of the offering is likely to intensify market competition as major contractors position themselves ahead of the 2027 start date. Supplier applications are currently being assessed by the CCS as the construction procurement phase advances.
