G-Cloud 15: What to Expect and How to Prepare Your Bid

G-Cloud 14 runs until September 2026. G-Cloud 15 — the next iteration of Crown Commercial Service's flagship cloud framework — is expected to open for applications in mid-to-late 2026. This guide covers what suppliers can expect from G-Cloud 15 and how to prepare a strong submission now, before applications open.

What Is G-Cloud 15?

G-Cloud 15 will be the fifteenth iteration of the Crown Commercial Service's framework for cloud-based technology services to UK public sector organisations. It will replace G-Cloud 14 when that framework expires in September 2026. G-Cloud 15 is expected to maintain the three-lot structure — Lot 1 Cloud Hosting, Lot 2 Cloud Software, Lot 3 Cloud Support — but CCS typically refines evaluation questions, updates technical requirements, and adjusts lot scope with each new iteration.

When Will G-Cloud 15 Open?

Based on previous G-Cloud timelines, applications are expected to open approximately 3–6 months before the G-Cloud 14 expiry in September 2026, putting the likely opening window at Q2 or Q3 2026. CCS typically publishes a Prior Information Notice (PIN) several months before applications open. Monitor the Find a Tender Service and CCS website for official announcements.

What to Expect From G-Cloud 15

Updated security requirements: Each G-Cloud iteration increases emphasis on cybersecurity. Cyber Essentials Plus and ISO 27001 are likely to become more prominent requirements on G-Cloud 15.

AI and emerging technology: CCS is increasingly interested in AI capabilities. Suppliers offering AI-powered services should prepare to describe their AI governance, data handling, and transparency practices clearly.

Sustainability: Carbon footprint data, sustainability certifications, and net-zero commitments are increasingly expected in G-Cloud submissions and likely to feature more prominently in G-Cloud 15.

Accessibility: Services used by public sector staff must comply with WCAG 2.1 AA accessibility standards. This is likely to be more prominently evaluated in G-Cloud 15 than in previous iterations.

Build case studies — collect references and quantified outcomes from public sector clients you have worked with on G-Cloud 14 or other routes

Refine service descriptions — analyse which services performed well on G-Cloud 14 and use this insight to write stronger descriptions for G-Cloud 15
Monitor CCS announcements — subscribe to CCS updates and set up monitoring for G-Cloud 15 news to be ready to submit on day one

Frequently Asked Questions

When exactly will G-Cloud 15 open?

No official date has been announced. Based on previous G-Cloud iterations, applications are expected to open in Q2 or Q3 2026, ahead of the G-Cloud 14 expiry in September 2026. Monitor the CCS website and Find a Tender Service for announcements.

Will existing G-Cloud 14 suppliers automatically transfer to G-Cloud 15?

No. Suppliers must apply for each new G-Cloud iteration. Being listed on G-Cloud 14 does not guarantee a place on G-Cloud 15.

Will G-Cloud 15 have new lots or categories?

CCS has not confirmed the G-Cloud 15 lot structure. Previous iterations maintained the three-lot structure with refinements. We will update this guide when official details are published.

How long does G-Cloud 15 last?

G-Cloud frameworks typically run for two years, potentially with a one-year extension. Based on this pattern, G-Cloud 15 would run from approximately late 2026 to late 2028.

Can new suppliers join G-Cloud 15 after it launches?

G-Cloud frameworks are closed to new applications after the initial application window. Suppliers must apply during the application period. This is different from a Dynamic Purchasing System (DPS), which remains open to new suppliers throughout its life.
