G-Cloud Bid Writing Software · CCS · Digital Marketplace

G-Cloud submission help for cloud suppliers.

Getting onto G-Cloud is a compliance exercise, not a scored tender — but your service definitions still have to pass the checks, and your descriptions still have to win buyers over once you are listed. BidWriter helps you draft compliant, clear service definitions and reuse them across G-Cloud iterations and further competitions.

Draft service definitions and descriptions, store them in a reusable Bid Library, track which G-Cloud iteration you are on, and catch further-competition opportunities through integrated tender discovery.

What is G-Cloud?

G-Cloud is a Crown Commercial Service (CCS) framework that lets UK public sector organisations buy cloud-based services without running a full tender every time. Suppliers list their services on the government's Digital Marketplace — increasingly referred to as the Cloud Marketplace — and public sector buyers search, compare and buy from those listings.

The framework is refreshed periodically. Each refresh is a new numbered iteration — for example G-Cloud 14 and G-Cloud 15 — and suppliers reapply at each refresh to keep their services listed. Iterations have historically come around roughly once a year, but the exact timing is set by CCS, so always check the current guidance for the iteration you are applying to.

For a buyer, G-Cloud is a fast, pre-approved route to compliant cloud procurement. For a supplier, it is a shop window: get your services listed correctly, and public sector buyers across central government, the NHS, local authorities and beyond can find and buy them.

The three G-Cloud lots

G-Cloud is structured into three lots. You apply to whichever lots match your services and list each individual service under the right lot.

Lot 1 · IaaS / PaaS

Cloud hosting

Infrastructure and platform services — compute, storage, networking, databases and managed hosting. The underlying cloud capacity that buyers run their workloads on.

Lot 2 · SaaS

Cloud software

Software accessed over the internet — applications hosted and delivered by the supplier, with the buyer using them as a service rather than installing and running them themselves.

Lot 3 · Setup & operate

Cloud support

Services that help buyers adopt and run cloud — planning, migration, implementation, training, and ongoing support around hosting and software services.

How applying to G-Cloud differs from a normal tender

This is the single most important thing to understand. Getting onto G-Cloud is not a competitively-scored tender. There is no invitation to tender (ITT), no bidder presentations, and no quality score that ranks you against other suppliers. Instead, you apply during an open application window by agreeing the framework declarations and terms and submitting your services.

For each service you typically submit a service definition document, a pricing document, applicable terms, and a service description. Framework entry is essentially a pass/fail compliance check against the published requirements — if your submission is complete and compliant, your service is listed.

The real competition happens after you are listed. Buyers search the marketplace, compare services, and then either award a contract directly or run a further competition between a shortlist of suppliers. That further competition is where you write a proper, tailored bid response — and where good writing wins or loses you the work.

What you submit per service

For every service you list, you provide a small set of documents and text. Each is checked for completeness and compliance rather than scored for quality — but each can hold up your listing if it is wrong.

Service definition document

A clear, accurate document describing what the service is, what it does, and how it is delivered — checked for compliance, not scored for quality.

Pricing document

Your pricing in the required format. Errors and inconsistencies in the pricing document are a common reason submissions get held up.

Service description text

The marketplace-facing text buyers read when they search. Must be genuinely descriptive — CCS rejects keyword-stuffing and marketing fluff.

Terms and declarations

Applicable terms and the framework declarations you agree to as part of joining. Missing or incomplete information can fail the compliance check.

Why writing still matters when entry is pass/fail

If framework entry is just a compliance check, why does it matter how well you write? Two reasons. First, your submissions have to pass those checks — CCS expects service definitions and descriptions to be clear, accurate and genuinely descriptive, and typically rejects content that is keyword-stuffed, vague, or makes non-compliant or unsupported claims. A poorly written service definition can keep your service off the marketplace.

Second, once you are listed, your service descriptions are what buyers read when they search the marketplace. Clear, accurate, well-structured descriptions help buyers find you, understand what you do, and shortlist you. And when a buyer runs a further competition, you write a full response to their specific requirements — a genuinely competitive piece of bid writing.

Common pitfalls that hold suppliers up or weaken their listings:

  • →Keyword stuffing service descriptions to game search — typically rejected by CCS and unhelpful to buyers who actually read them.
  • →Vague or non-compliant service definitions that do not clearly describe what the service is and how it is delivered.
  • →Errors and inconsistencies in the pricing document — a frequent cause of submissions being held up or returned.
  • →Missing assured information or incomplete declarations, which can fail the framework compliance check.
  • →Treating the further competition like the framework stage — when a buyer runs one, you need a proper, tailored bid response, not just your listing.

How BidWriter helps G-Cloud suppliers

BidWriter helps you write and organise your G-Cloud submissions and further-competition responses. Meeting the current CCS compliance requirements always remains your responsibility as the supplier.

Draft clear, compliant service definitions

The AI helps you draft service definitions and descriptions that are clear, accurate and genuinely descriptive — the kind of content that passes CCS compliance checks, not keyword-stuffed filler.

Reuse evidence with the Bid Library

Store your service definitions, descriptions and supporting evidence once. Refine and reuse them across G-Cloud iterations (such as G-Cloud 14 and 15) and across further-competition responses, instead of rewriting from scratch each refresh.

Track iterations with the framework manager

Keep track of which G-Cloud iteration you are on and keep an eye on renewal and refresh windows, so you do not miss the open application window when CCS introduces the next iteration.

Catch further competitions via WinAContract

Integrated tender discovery through WinAContract surfaces relevant public sector opportunities — including further-competition opportunities — so you can respond when buyers run them off the framework.

G-Cloud submission — questions answered

What is G-Cloud?

G-Cloud is a Crown Commercial Service (CCS) framework that lets UK public sector organisations buy cloud-based services without running a full tender each time. Suppliers list their services on the government's Digital Marketplace (now also referred to as the Cloud Marketplace), and public sector buyers search, compare and buy from those listings. G-Cloud is refreshed periodically — successive iterations are numbered, such as G-Cloud 14 and G-Cloud 15 — and suppliers reapply at each refresh to stay on the framework.

What are the three G-Cloud lots?

G-Cloud is structured into three lots. Lot 1, Cloud hosting, covers infrastructure and platform services (IaaS and PaaS) such as compute, storage, networking and managed hosting. Lot 2, Cloud software, covers software accessed over the internet (SaaS) — applications hosted and delivered by the supplier. Lot 3, Cloud support, covers services that help buyers set up, migrate to, or operate cloud services, such as planning, implementation, training and ongoing support. You apply to whichever lots match your services and list each service under the right lot.

How do I apply for G-Cloud 14 or 15?

You apply during an open application window, which CCS opens periodically — roughly once a year for each new iteration. Within the window you register on the relevant platform, agree the framework declarations and terms, and submit each service you want to list. For every service you typically provide a service definition document, a pricing document, applicable terms, and a service description. Entry is essentially a compliance check against the requirements rather than a scored competition. Always check the current CCS and Digital Marketplace guidance for the exact requirements and timing of the iteration you are applying to.

Is G-Cloud competitive at the framework stage?

No, not in the way a normal tender is. Getting onto G-Cloud is not a competitively-scored exercise with an invitation to tender (ITT), bidder presentations and a quality score. Framework entry is essentially pass or fail against the published requirements — if your application and per-service submissions are complete and compliant, your services are listed. The competition happens afterwards, on the marketplace, when buyers search the listings and either award a contract directly or run a further competition between shortlisted suppliers.

How are G-Cloud service definitions assessed?

At the framework stage, service definitions are checked for completeness and compliance against the requirements rather than scored for quality. CCS expects service descriptions to be clear, accurate and genuinely descriptive of the service — and typically rejects content that is keyword-stuffed, vague, or makes non-compliant or unsupported claims. So while there is no quality score for entry, a service definition that fails the compliance and assurance checks can keep your service off the marketplace.

Why does writing matter if G-Cloud entry is pass/fail?

Writing matters for two reasons. First, your submissions still have to pass the compliance and assurance checks — poorly written, vague or non-compliant service definitions and descriptions can be rejected. Second, once you are listed, your service descriptions are what buyers read when they search the marketplace; clear, accurate, well-structured descriptions help buyers find and shortlist you. And when a buyer runs a further competition, you write a proper response to their specific requirements — that is a competitive piece of writing, just like any other bid.

Can BidWriter help with G-Cloud submissions?

Yes. BidWriter helps you draft clear, compliant service definitions and service descriptions, and stores them in a reusable Bid Library so you can refine and reuse them across G-Cloud iterations (such as G-Cloud 14 and 15) and across further-competition responses. The framework manager helps you track which G-Cloud iteration you are on and keep an eye on renewal and refresh windows, and integrated tender discovery via WinAContract helps you catch further-competition opportunities. BidWriter helps you write and organise — meeting the current CCS compliance requirements remains your responsibility as the supplier.

When does the next G-Cloud application window open?

CCS opens G-Cloud application windows periodically, typically around once a year as each new iteration is introduced, but the exact dates change for each iteration and are not fixed in advance. We do not publish a specific future date here because it can change. Check the current Crown Commercial Service and Digital Marketplace guidance for the live window and requirements, and use BidWriter's framework manager to keep track of when you need to reapply.
