G-Cloud 15 is the latest framework agreement under the Procurement Act 2023, allowing UK public sector buyers to buy cloud hosting, software, and support services from pre-approved suppliers through a streamlined digital marketplace. G-Cloud is only reviewed every couple of years, so if you miss the G-Cloud 15 deadline, you’ll be waiting until at least 2027 for your next chance to become listed on a marketplace that has facilitated over £20 billion of public sector spend.
Replacing G-Cloud 14, this version introduces a refreshed lot structure, clearer guidance, and updated requirements designed to keep pace with emerging technologies and modern cloud delivery models.
What is a ‘lot’?
A “lot” is a formal category within a public sector framework that groups similar types of services together, helping buyers and suppliers understand where specific offerings sit.
How do lots interact with G-Cloud 15?
Lots act as the core organising structure of the G-Cloud framework.
Each one has:
- A defined scope (e.g., cloud hosting, SaaS, cloud support)
- Its own entry requirements
- Specific evaluation and compliance criteria
Suppliers choose the lot – or multiple lots – that best reflect the services they wish to make available to public sector buyers.
What does choosing a ‘lot’ mean for a supplier?
For a supplier, choosing a ‘lot’ means deciding which category best aligns with their offering, ensuring their services appear in the right place when public sector buyers search.
What are the lots in G-Cloud 15?
G-Cloud 15 is structured into the following 5 lots:
- Lot 1a: Cloud hosting IaaS/PaaS
- Lot 1b: Above Official security hosting
- Lot 2a: Infrastructure SaaS
- Lot 2b: General SaaS
- Lot 3: Cloud support
