The Government Commercial Agency has launched G-Cloud 15, creating a public-sector cloud procurement framework valued at about £14bn over four years and introducing a structure intended to make it easier for new suppliers to enter during its lifetime.
The framework consolidates three previously separate procurement routes — Cloud Compute 2 and the different lots within G-Cloud 14 — into a single commercial agreement. It is expected to open for public-sector use later in August and will cover cloud requirements across organisations including NHS trusts and local authorities.
Government estimates that about £3bn of public-sector cloud expenditure will flow through G-Cloud 15 each year. Call-off contracts can run for up to 60 months, extending the potential duration of supplier relationships beyond the framework’s own four-year term.
Around 90% of suppliers admitted to the framework are small and medium-sized businesses. G-Cloud has long provided technology companies with a route into public-sector cloud procurement without requiring a completely new commercial mechanism for each buyer, although admission to a framework does not guarantee contract awards.
The latest iteration introduces an open-framework structure under the Procurement Act 2023. New and growing suppliers will be able to join during an 18-month reopening period after launch and at further intervals during the four-year term.
That change reduces one of the structural limitations of previous frameworks, where a supplier that missed the initial application period could face a lengthy wait before another opportunity to join. In fast-moving technology markets, that delay could exclude products or providers that did not exist, or were not commercially mature, at the point when a framework was first established.
Philip Orumwense, commercial director and chief procurement officer for technology at the agency, said G-Cloud 15 was “a genuine step forward for small and medium-sized businesses wanting to work with the government.”
Suppliers will also face what the agency describes as the framework’s most comprehensive assessment process to date, covering quality, technical capability, and price. Public buyers can still carry out deeper evaluations and competitions for individual requirements after suppliers have been admitted.
The combination of wider access and stronger qualification changes the competitive balance in two directions. Smaller technology companies gain more opportunities to enter the market during the framework term, while buyers receive a more structured basis for assessing suppliers before individual contracts are called off.
G-Cloud 15 also lands alongside wider changes to public procurement. Separate reforms are increasing the emphasis placed on jobs and skills in larger government contracts, while G-Cloud deals more directly with how cloud products and services are made available to public bodies.
The commercial opportunity extends beyond the £14bn headline value. Public-sector cloud procurement increasingly encompasses infrastructure, software, migration, data management, cybersecurity, managed services, specialist platforms, and the integration of systems across multiple environments.
Bringing more of those requirements into one framework could simplify the route to market, but it also increases the importance of accurate product classification, transparent pricing, and evidence that suppliers can support public-sector workloads at scale.
The reopening mechanism may prove particularly relevant as artificial intelligence, data platforms, cybersecurity services, and cloud architecture continue to develop faster than traditional procurement cycles. A four-year framework risks becoming outdated if its supplier base is fixed on the day it begins.
Allowing new businesses to join during the term creates a route for more recent products and services to reach public buyers without waiting for a replacement framework. It also means incumbent suppliers will face new competition during the agreement rather than competing only against the original cohort.
G-Cloud 15 is the first version launched since the Government Commercial Agency began operating on 1 April 2026, combining the Crown Commercial Service with several Cabinet Office commercial teams. G-Cloud 14 will remain operational until 28 October 2026, with existing call-off contracts needing to be signed before that framework expires.
The eventual distribution of the £14bn opportunity will be determined by individual buying decisions rather than framework membership. The revised structure nevertheless gives cloud suppliers a larger and more flexible route into one of the UK’s biggest institutional technology markets, while raising the standard of evidence required to compete for that spending.
