G-Cloud 15 framework opens a £14bn route for UK public-sector cloud buying

The UK Government Commercial Agency has launched the G-Cloud 15 framework, a four-year public-sector buying arrangement valued at about £14 billion. It consolidates three cloud procurement frameworks into one, and the government says roughly 90% of approved suppliers are small and medium-sized enterprises, though no share of spending is reserved for them.

The £14 billion figure is an estimated value of cloud business that could flow through the framework, not a committed contract award. GCA expects around £3 billion of annual public-sector cloud spending to use the arrangement, which covers hosting, software and support services for bodies including NHS trusts and local authorities.

For suppliers, the practical distinction is material. G-Cloud is a list of pre-approved vendors that public-sector buyers can use to procure services. Being admitted provides access to opportunities, not revenue: buyers can conduct further assessment and run competitions when awarding individual call-off contracts.

What changes with the G-Cloud 15 framework?

G-Cloud 15 combines Cloud Compute 2 with Lots 1 to 3 and Lot 4 of G-Cloud 14 into a single commercial agreement. The agency says the change will give buyers one route to procure their cloud requirements, while suppliers can offer services under a revised classification system intended to improve how they appear in buyer searches.

For teams selling cloud infrastructure and adjacent services, the framework also introduces an open-framework format under the Procurement Act 2023. New suppliers and growing companies will have an 18-month window after launch to join, followed by regular opportunities during the four-year term, according to GCA. That replaces the longer wait between fixed framework iterations.

• GCA says every supplier was assessed on quality, technical capability and price.
• Individual call-off contracts can last up to 60 months.
• About 90% of suppliers on the framework are SMEs, according to GCA.
• G-Cloud 14 remains available until 28 October 2026; call-off contracts under that framework must be signed by then.

The agency, formed in April through the merger of Crown Commercial Service and Cabinet Office commercial teams, describes G-Cloud 15 as the programme’s largest revision since G-Cloud began in 2012. Public-sector purchases are scheduled to begin on 17 September, according to The Register.

The test is whether the supplier mix converts into contracts. Independent reporting has said US hyperscalers have typically been major G-Cloud winners, while a Cabinet Office digital office document warned that cloud adoption could produce concentration and vendor lock-in that weaken the government’s negotiating position. GCA’s measures reduce some entry barriers, but the launch provides no evidence yet that SME suppliers will receive a larger portion of actual spending.
