Every G-Cloud 15 application Nexus submitted in the first window was accepted, most of them for technology companies headquartered outside the UK. The framework did not make that easy. These are the eight obstacles that decided the outcome, and how each was cleared.
G-Cloud 15 opened for applications on 23 October 2025 and closed at 3:00pm on 30 January 2026, with Christmas in the middle. It was the first G-Cloud let under the Procurement Act 2023, with a restructured lot model, new conditions of participation and registration through the Central Digital Platform rather than the old supplier portal. For a supplier headquartered outside the UK, it was also a compressed education in how UK public procurement thinks.
Nexus ran a campaign across that window for technology suppliers, most of them international. Every application we submitted was accepted. That result was not a matter of filling in forms well. It came from clearing eight obstacles that sit between an overseas company and a live UK framework listing, several of which only become visible after the deadline has passed.
1. The account has to belong to the supplier
The Central Digital Platform account is the supplier’s government identity. It holds the declarations, receives the access codes for contract signatures, and carries every future update. Registering it under an adviser’s email address is convenient for a week and a liability for years, because the supplier then does not control its own account.
We registered every account to the client, on a shared mailbox such as tenders@ or procurement@ so that verification codes reached the right people whoever was on leave, and added ourselves as an administrator for the duration of the project. That decision looks like housekeeping. It is the difference between a listing that is an asset and one that is a dependency.
2. Beneficial ownership is a question about people, not companies
Under the Act a supplier confirms the individuals who ultimately own or control it: anyone holding 25 per cent or more of the shares or voting rights. International groups routinely answer this with the name of the parent company, which is not an answer. Where the local entity is owned by a holding company, the question moves up the structure to the individuals controlling that.
For several clients this meant a short exchange with the group’s legal team and a clear statement of who, if anyone, met the threshold. Where nobody did, the correct answer was that there was no individual beneficial owner above 25 per cent. Getting this wrong at registration surfaces later, in a live procurement, when there is no time to fix it.
3. Identifiers that UK buyers assume you already have
A D-U-N-S number, a UK-recognised company registration, a VAT position and a registered address are assumed by the platform and by buyers. Overseas suppliers often hold some and not others. We obtained D-U-N-S numbers directly from Dun and Bradstreet, populated everything available from public records first, and asked clients only to confirm rather than to research. It is faster, and it produces fewer errors than asking a busy leadership team to fill in a form.
4. The reference that unlocks revenue
The obstacle that decides most international applications is the Technical Ability Certificate. It is a signed reference from a public sector customer for a relevant contract worth at least £25,000 excluding VAT and active inside the framework’s reference window, and one is needed per lot. A supplier cannot enter a call-off contract from the framework until the customer has signed it, so an unsigned certificate blocks revenue, not just the application.
Three things made the difference. First, identifying which of each client’s existing contracts qualified, which for international suppliers often meant a public sector customer outside the UK and a careful read of the eligibility wording. Second, briefing the customer before the request arrived, because the signature request comes from the platform’s notification address and is routinely caught by mail filters. Third, having the framework authority’s offline route ready, so that where the platform email never arrived, the certificate was completed on the offline template and accepted.
5. An evidence list written for UK companies
The platform’s evidence section lists dozens of certificates, accreditations, insurance documents and policies. Most do not apply to any one supplier, and international clients tend to read the list as a set of requirements rather than a menu. We sent the full list with a plain statement that not everything was expected, and asked who was best placed to collect what did apply.
Insurance was the recurring problem. The platform offers specific levels of cover for employers’ liability, public liability, product liability and professional indemnity, and the correct entry is the one matching the cover actually held, evidenced by one current certificate showing the level and the expiry date. Selecting the general combined entries, or an aspirational level, creates a discrepancy that has to be unpicked in clarification. Policies followed the same pattern: prompt payment, social value, business continuity and, where requested, a corporate resolution plan, each drafted or adapted to the UK expectation rather than translated from a group document.
6. Lots are assigned, not guessed
G-Cloud 15 restructured the lots into cloud hosting, with a separate lot for services above OFFICIAL, infrastructure software as a service, software as a service and cloud support. Each has its own conditions of participation, including financial thresholds and, for hosting above OFFICIAL, Cyber Essentials Plus. The lot for each service was taken from the framework authority’s own message or the submitted service record, and corrected where the two disagreed, rather than inferred from a description. That discipline removed a whole category of clarification.
7. Writing for a buyer who is searching, not reading
A G-Cloud listing is found by a buyer typing what they need into a search box. The updated taxonomy and filters in G-Cloud 15 made this sharper. Service descriptions written in a supplier’s internal product language do not surface; descriptions written in the language a UK buyer uses do. Every service was written to its lot, in the buyer’s terms, with a service definition that answered scope, onboarding and offboarding, service levels, support and security before the buyer had to ask, and a pricing structure that would survive a call-off.
For international suppliers this was where the accent showed most. Case studies, security answers and social value commitments written for another market read as foreign to a UK evaluator. Rewriting them for the UK reader, without changing the substance, is a large part of what made the listings credible.
8. Time, and the holiday in the middle of it
Fourteen weeks from tender to deadline sounds generous until the December clarification deadline and the Christmas period are removed. We ran two structured sessions with each client, one on social value, policies and carbon reduction, one on service structure and commercial positioning, and did the drafting, platform work and follow-up ourselves. Nothing was submitted without the client’s sign-off, and every application went in ahead of the deadline rather than in the final hour.
What acceptance is, and what it is not
A framework listing is eligibility. It is not demand. The suppliers who have done best since the framework went live are the ones who treated acceptance as the start: a single-service brochure per listing, aligned line by line with the published description; buyer engagement ahead of any search; and bids for further competitions written to the criteria rather than the brochure. That is the work of a growth programme, and it is where a listing becomes revenue.
The next window
G-Cloud 15 operates as an open framework, designed to reopen to new suppliers during its term. The eight obstacles above do not get easier with less time. Suppliers who intend to be on the framework at the next opening are preparing the account, the beneficial ownership position, the references and the evidence now, so that the application is a submission rather than a scramble.
