What the buyer list tells suppliers

Seven of the top ten are central government departments or arms of the central government. The largest single buyer, HMRC, spent nearly three times what NHS England spent. For suppliers whose primary market is the NHS, the overall top buyer list needs filtering to your buyer type and category before it is commercially useful.

NHS England at £23.8 million is significant in absolute terms, but it represents NHS England's own commissioning rather than the procurement activity of individual NHS trusts. The full NHS picture on G-Cloud requires looking beyond the top ten. Individual trusts and ICBs also call off through G-Cloud, but their spend is distributed across a long tail of buying organisations that the headline figures do not capture.

For suppliers with a defence or security proposition, the Ministry of Defence, Defence Digital, and the Defence Infrastructure Organisation together spent £99.7 million, more than any other buyer grouping on the framework.

Understanding which buyer types are most active in your specific category, and at what scale, is the commercial question that determines whether a G-Cloud position generates revenue or sits dormant. Our guide to what is the G-Cloud framework and how do suppliers use it covers the mechanics of how call-offs work in more detail.

The concentration problem on the supply side

The buyer picture is concentrated. So is the supplier picture, though less so than many suppliers assume.

The top ten suppliers on G-Cloud 14 captured approximately £247 million, around 15% of total spend. Softcat led at £36.3 million, followed by AWS and Microsoft at £32.8 million each. The remaining 85% of spend went to more than 1,600 other suppliers.

A framework where the top three suppliers capture just 6% of total spend leaves the competitive dynamic more open than the headline names suggest.

What changed on G-Cloud 15

G-Cloud 15 launched in August 2026 with a £14 billion ceiling, the largest iteration in the framework's history. It operates as an open framework under the Procurement Act 2023, which means suppliers who missed the initial application window can apply again at 18 and 24 months after launch. Cyber Essentials certification is now mandatory for all lots. Evaluation scoring now explicitly weights quality and social value alongside price.

The buyer population on G-Cloud 15 will broadly mirror G-Cloud 14's. The same central government departments, NHS organisations, and wider public sector bodies. The first six months of a new framework iteration tend to see buying patterns reset as procurement teams assess the new lot structure and establish new supplier relationships. That window is the most commercially significant period for suppliers already listed.
