Crown Commercial Service Frameworks: Supplier Guide

What is Crown Commercial Service?

Crown Commercial Service (CCS) is an executive agency of the Cabinet Office responsible for improving the government's commercial and procurement capability. Its primary function is to manage commercial agreements — framework agreements, dynamic purchasing systems, and catalogue arrangements — that public sector buyers can use to procure goods and services without running their own full procurement exercise from scratch.

CCS negotiates the terms, pricing mechanisms, and quality standards for each framework on behalf of the Crown and wider public sector. A buyer using a CCS framework benefits from pre-negotiated terms, compliance with procurement regulations, and access to a pre-vetted supplier pool. A supplier on a CCS framework gains access to thousands of potential buyers across central government, local authorities, NHS, emergency services, education, and beyond.

CCS manages several hundred commercial agreements across categories including technology, professional services, buildings, people, and corporate services. The total spend channelled through CCS agreements exceeded £30 billion in recent years, making it the single largest route to public sector procurement for many categories of supplier.

The Digital Marketplace: G-Cloud and DOS

The Digital Marketplace is the online platform through which buyers and suppliers interact with two major CCS digital frameworks: G-Cloud and Digital Outcomes & Specialists (DOS). It is operated jointly by CCS and the Government Digital Service.

G-Cloud (RM1557) is a catalogue framework for cloud-based technology services. Suppliers list their services — cloud hosting, cloud software, or cloud support — as individual service records on the marketplace. Buyers search the catalogue, compare supplier offerings, and can award contracts by direct selection without running a further competition. G-Cloud operates in iterations: each iteration is a new version of the framework with an application window, after which the catalogue is refreshed. G-Cloud 14 is the current iteration. The catalogue contains thousands of services from hundreds of suppliers — standing out requires strong, keyword-rich service descriptions and clear, transparent pricing.

Digital Outcomes & Specialists (DOS) is a further competition framework for digital outcomes and specialist resource. Unlike G-Cloud, buyers cannot simply select a supplier from a catalogue — they must run a mini-competition, publishing a requirements brief and evaluating responses from interested suppliers. DOS is well suited to outcome-based digital delivery (agile development, service design, user research) and to specialist contracting (specific technical skills for defined periods).

The Digital Marketplace application process for both frameworks is managed online. Suppliers complete service submissions or capability declarations, agree to the framework terms, and submit for assessment. CCS reviews submissions for compliance rather than running a competitive evaluation — meaning the barrier to listing is lower than for competitive frameworks, but the commercial opportunity depends on how actively buyers engage with the catalogue.

Key CCS frameworks

The following table covers a selection of the most widely used CCS frameworks. RM numbers are the authoritative identifier — always cross-reference with the CCS website as frameworks are periodically superseded.

Finding the right frameworks for your business

CCS manages a large number of frameworks and it is not realistic — or commercially sensible — to pursue every one that could theoretically accommodate your services. The right approach is to identify the two or three frameworks that represent the highest-volume route to buyers most likely to need what you offer.

Start with the CCS agreements finder on the CCS website, filtering by your category of spend. Review the scope of each framework and the lots it contains. Check the list of eligible buyers — not all frameworks are open to all public sector bodies. Look at the framework's published spend data (CCS releases annual management information reports) to understand how much activity actually flows through it.

Consider whether the framework operates as a catalogue (direct award) or mini-competition. For organisations with limited bid resource, catalogue frameworks like G-Cloud generate call-offs with low per-transaction overhead. Mini-competition frameworks require a response for each opportunity, which is more resource-intensive but allows tailored differentiation.

RevnIQ tracks which frameworks are associated with live and historical contracting activity across your target buyer types — this can help you identify the frameworks generating the highest volume of relevant call-offs rather than relying solely on framework scope descriptions.

The application process

CCS framework applications fall into two broad categories: open/rolling applications (where suppliers can apply at any time or during periodic windows) and competitive applications (where a one-time competition determines which suppliers are appointed for the framework's duration).

Open applications (G-Cloud, some DPS arrangements) require suppliers to complete a service or capability submission online, agree to the framework terms and pricing mechanisms, and pass a compliance review. CCS does not score submissions against each other — it assesses whether each submission meets the minimum requirements. Rejection typically results from incomplete information, pricing outside permitted parameters, or service descriptions that do not match the framework scope. Applications can usually be revised and resubmitted within the same window.

Competitive applications (professional services frameworks, specialist technology frameworks) are full procurement exercises. CCS publishes a Prior Information Notice (PIN) or Contract Notice, runs a competitive evaluation across selection and quality criteria, and appoints a defined number of suppliers. These applications require the same quality of response as an ITT — a weak response means exclusion from the framework for its entire duration, which may be three to four years.

For competitive frameworks, monitor the CCS pipeline publication (updated quarterly) to anticipate when frameworks in your category are due for re-procurement. Being prepared — with updated case studies, current financial information, and a strong quality response — months before the application window opens significantly improves your chances.

How call-offs work from a supplier perspective

A call-off is the individual contract placed by a buyer using a framework. The framework sets the overarching terms; the call-off applies them to the specific requirement. From a supplier's perspective, call-offs can arrive in two ways: a buyer contacts you directly (direct award frameworks), or a buyer publishes a mini-competition brief and invites responses from shortlisted framework suppliers.

On direct award frameworks, the primary commercial activity is ensuring your listing is discoverable and compelling. On G-Cloud, this means well-written service descriptions with the terminology buyers actually use in searches, clear capability statements, transparent pricing, and up-to-date case studies in your service record. Buyers doing due diligence before a direct award may also check your company's public sector track record through sources like Contracts Finder.

On mini-competition frameworks, the commercial activity is responding to briefs efficiently and compellingly. Buyers typically issue requirements via the procurement portal or the Digital Marketplace message function. Response windows are shorter than full procurement exercises — often five to fifteen working days. Having templated capability statements, rate cards, and case studies ready to deploy is essential for competitive responsiveness.

Call-off contracts are subject to the framework terms and conditions, which you agreed to at application stage. Review the call-off order form carefully — particularly the statement of work, deliverables, payment milestones, and any specific KPIs — before signing. Variations from the standard framework terms are often not permitted, but buyers sometimes try to introduce bespoke conditions that may conflict with your obligations.
