Digital Marketplace (G-Cloud, DOS)

The Digital Marketplace (available at digitalmarketplace.service.gov.uk) is operated by the Crown Commercial Service (CCS) and the Central Digital and Data Office. It hosts two major procurement frameworks: G-Cloud, for buying cloud hosting, software, and support services; and Digital Outcomes and Specialists (DOS), for procuring teams or individuals to deliver specific digital outcomes and projects. Together, these frameworks make the Digital Marketplace one of the most significant routes to market for technology suppliers selling to UK public sector buyers.

What is the Digital Marketplace (G-Cloud, DOS)?

G-Cloud is a framework for buying commodity cloud services (infrastructure as a service, platform as a service, software as a service, and cloud support). Suppliers apply to join the G-Cloud framework during periodic application windows, listing their specific services with defined prices. Buyers then search the marketplace catalogue and award contracts directly to listed suppliers without running a full tender competition, using the catalogue search as the basis for direct award within the framework rules.

The Digital Outcomes and Specialists (DOS) framework works differently: buyers publish specific requirements (an outcome or specialist need), and suppliers on the framework respond with proposals. The buyer then evaluates responses and selects a supplier through a defined assessment process. DOS is used for bespoke software development, data science projects, cybersecurity assessments, and similar discrete digital engagements.

Both frameworks operate under the Crown Commercial Service's framework agreement structure, which means individual call-offs are made under the procurement rules established when the framework was set up. Above-threshold framework awards are published on Contracts Finder. The frameworks are accessible to all UK public sector buyers including central government, local authorities, NHS trusts, universities, and housing associations.

Why it matters for bidders

For digital and technology suppliers, the Digital Marketplace frameworks represent a major route to UK public sector revenue. The G-Cloud catalogue approach is particularly attractive for smaller technology companies: once listed, the service can be purchased by any public sector buyer without a further procurement exercise, significantly reducing the sales cycle. The barrier to entry is the framework application process rather than individual competitive tenders.

DOS provides access to digital project work that goes through a lightweight competitive process, with shorter timelines than a full tender procedure. The framework's direct award mechanism (for small requirements) and competition mechanism (for larger ones) give buyers flexibility, which in turn means a relatively steady stream of opportunities for suppliers on the framework.

Example

A cloud software company offering a document management solution applies to join G-Cloud during an application window, listing its software as a service offering with defined pricing tiers and a clear service description. Once listed, a housing association searches the G-Cloud catalogue for document management tools, finds the company's listing, checks the price and service definition, and awards a direct call-off contract worth 45,000 GBP per year. No competitive tender was needed because the framework rules permit direct award for commodity services.

Frequently Asked Questions

How often does G-Cloud accept new applications?

G-Cloud runs periodic application windows, typically once or twice a year. Suppliers can join the framework during an open application window, and once accepted their services are listed in the catalogue for the duration of the framework (usually two to four years, with possible extensions). Suppliers should monitor Crown Commercial Service (CCS) announcements for window opening dates.

Can European suppliers outside the UK use the Digital Marketplace?

The Digital Marketplace frameworks are open to suppliers from WTO GPA signatory countries, which includes EU member states. However, the practical focus is UK-based or UK-operating suppliers. Overseas suppliers should check the framework terms and conditions and consider whether they have the UK presence and support capability that public sector buyers typically expect.

Is DOS being replaced?

The DOS framework has gone through multiple iterations (DOS, DOS2, DOS3, DOS4, DOS5, DOS6) and CCS periodically refreshes the framework. Suppliers should monitor CCS announcements for the current live framework version and any upcoming replacement frameworks, as the specific framework name and version affects which call-off rules apply.
