The award notice publishes 4,232 supplier identities: 4,231 named and one section 94 placeholder covering 16 withheld Lot 1b awardees. We resolved every named supplier to a real organisation and audited the full recorded public-sector track record each one brings onto the framework: the contracts, the buyers and the values. No other public list of this framework does that.
We resolved 4,231 named identities to 4,210 organisation records and counted 61,861 confirmed contract awards across them, with framework ceilings, cancellations and anything ambiguous excluded before a single number was published.
54,785 of those awards carry an exact published value, totalling £79.35bn. Every figure is a floor: it counts only what buyers published, which is exactly why you can trust it.
| Measure | Figure |
|---|---|
| Published supplier identities | 4,232 (4,231 named; 1 placeholder covering 16 withheld Lot 1b awardees) |
| Distinct matched organisation records | 4,210 |
| Organisation records with confirmed awards | 2,514 (59.7%) |
| Confirmed organisation × canonical-procurement award participations | 61,861 |
| Participations with an exact published GBP supplier allocation | 54,785 (88.6%) |
| Exact published GBP supplier allocations | £79.35bn |
| Median participations among organisations with confirmed awards | 5 |
Read this as the framework's inheritance, not anything G-Cloud 15 has sold. An award participation means one named supplier organisation associated with one canonical awarded procurement after strict family-level exclusions. It is not necessarily a separately signed contract, and the allocated-value column is not a total-sales measure.
| Group | Share of exact allocated value | Share of award participations |
|---|---|---|
| Top 10 organisations | 26.3% | 12.1% |
| Top 50 organisations | 65.1% | 36.8% |
| Top 100 organisations | 79.8% | 47.0% |
| Top 500 organisations | 96.2% | 77.1% |
The top 50 organisation records hold 65.1% of the exact allocated value and 36.8% of confirmed award participations in the snapshot.
Use it to set expectations before you plan a G-Cloud 15 push. The catalogue is flat, the public award record is not. This is concentration in the suppliers' wider five-year record, not concentration of G-Cloud 15 revenue.
| Size | Organisations | With confirmed awards | Award participations | Valued participations | Exact allocated value |
|---|---|---|---|---|---|
| SME | 3,672 | 2,055 (56.0%) | 20,362 | 17,693 | £11.51bn |
| Large | 534 | 455 (85.2%) | 41,253 | 36,875 | £67.75bn |
| Mixed/ambiguous | 4 | 4 (100.0%) | 246 | 217 | £89.2m |
At published-identity level, 3,686 of 4,231 named entries (87.1%) are declared SMEs. Once shared identities are collapsed, the SME organisation bucket holds 14.5% of the exact allocated value.
The large-organisation bucket carries 5.9 times the exact allocated value of the SME bucket. Four organisation records have mixed or ambiguous size because their published identities disagree; keeping them separate makes the three rows reconcile to the headline.
If you are benchmarking an SME, use the SME row and the active-SME table rather than treating the whole framework as one comparable peer group.
| Lot | Organisation records | With confirmed awards | Award participations | Valued participations | Exact allocated value |
|---|---|---|---|---|---|
| 1a Cloud hosting (IaaS/PaaS) | 93 | 75 (80.6%) | 14,285 | 13,089 | £24.46bn |
| 1b Hosting above OFFICIAL | 16 withheld awardees | withheld | withheld | withheld | withheld |
| 2a Infrastructure software (iSaaS) | 311 | 233 (74.9%) | 18,151 | 16,570 | £31.87bn |
| 2b Software as a service | 2,733 | 1,759 (64.4%) | 47,518 | 41,866 | £60.92bn |
| 3 Cloud support | 2,271 | 1,338 (58.9%) | 47,024 | 42,430 | £68.98bn |
Lot rows overlap because 940 named organisation records hold more than one lot. The history is each lot cohort's wider five-year record, not value awarded through that lot.
The narrow cohort still has the higher incidence of confirmed public award evidence: 75 of 93 Lot 1a organisation records (80.6%), versus 1,338 of 2,271 on Lot 3 (58.9%).
These values must not be summed across lots or read as lot sales. An organisation's same historical participation and allocation appears in every G-Cloud 15 lot it holds.
The award notice's structured data shows a single Lot 1b supplier because all 16 awardees are withheld under section 94 and sit behind one placeholder row. The notice text states the real figure: 16. Anyone building this table by parsing the JSON will publish "1". We cannot match award history to suppliers whose names are withheld, so Lot 1b is excluded from the track-record analysis entirely.
| Lots held | Organisations | With confirmed awards | Award participations | Valued participations | Exact allocated value |
|---|---|---|---|---|---|
| 1 lot | 3,270 | 1,841 (56.3%) | 26,705 | 23,072 | £25.69bn |
| 2 lots | 733 | 502 (68.5%) | 16,802 | 14,947 | £21.42bn |
| 3 lots | 156 | 124 (79.5%) | 6,747 | 6,075 | £11.25bn |
| 4 lots | 51 | 47 (92.2%) | 11,607 | 10,691 | £20.98bn |
Read this as a correlation, not a tactic. Suppliers with broad enough offerings to qualify for four lots are mostly large integrators with long public sector histories. Applying for extra lots you cannot deliver will not move you up this table.

| Mixed/ambiguous | 6 | 5 (83.3%) | 1,163 | 1,050 | £926.1m |
London and the South East hold 48.8% of organisation records and 68.5% of exact allocated value. Scotland, Wales and the North East together hold 7.5% of organisations and 0.9% of value.
Region is the registered-address region from the supplier identity. Six shared organisation records span conflicting regions and are kept in the mixed/ambiguous row so this table reconciles to the headline.

One row per organisation record. Shared G-Cloud 15 identities are shown together. Values are exact GBP supplier allocations only; procurement totals and framework ceilings are excluded.
The buyer count separates concentrated records from broad ones. Within this value-ranked table, Softcat has confirmed participations across 496 distinct buyers. The most frequent-buyer field identifies the buyer appearing most often in each organisation's strict evidence set; it is not a claim of exclusivity or incumbency.
SME status is self-declared when a supplier applies. Declared SMEs whose recorded public-sector value alone exceeds £75m over the window are left out of this table, because at that scale the label stops telling you anything.
| # | Organisation | Award participations | Valued | Exact allocated value | Buyers | Region |

Look at buyer breadth alongside participation count. GatenbySanderson has 299 confirmed award participations across 159 buyers; SmartSourcing Limited has 298 across 15. Those are different public-sector selling patterns, not better and worse versions of one model.

67,612 supplier evidence rows classified at canonical-procurement-family level.
A confirmed award participation is one named supplier organisation associated with one canonical awarded procurement after the whole procurement family is classified. Ordinary awards and confirmed call-offs are retained. Framework and DPS parents, cancellations and ambiguous framework families are excluded before aggregation.
The previous rule accepted any award notice naming 20 or fewer suppliers. On this snapshot it would have admitted 2,710 rows that the strict family-level method excludes. Those rows carried £17.55bn in source value fields before the stricter allocation checks, which is why supplier count cannot stand in for award type.
A framework flag alone is not enough either: genuine call-offs can carry framework metadata. The family classification distinguishes the purchasing vehicle from the transaction made under it.
| Why a value is not in the £ total | Evidence rows |
|---|---|
| No exact supplier allocation | 11,725 |
| Excluded framework/DPS parent family | 5,198 |
| Exact allocation over £250m, pending review | 80 |
| Non-GBP or unknown currency | 103 |
| Excluded cancelled family | 132 |
| Framework ceiling, not supplier spend | 380 |
| Excluded ambiguous framework family | 421 |
Reasons are evidence-level diagnostics and are not a second award-participation total.
The £ figure uses positive, exact GBP supplier allocations only. It does not split a shared procurement total, treat a framework ceiling as spend, or convert an unknown currency. Exact supplier allocations above £250m are held out pending manual review; the confirmed participation can remain in the count while its value stays outside the £ total.
You are in a catalogue with thousands of entries. The strict history above shows where comparable supplier organisations have confirmed published award evidence and which buyers recur in that evidence. Use it as a research lead, not proof of a current incumbent.
G-Cloud 15 is an open framework under section 49 of the Procurement Act 2023, so it must reopen to new suppliers between terms. The first reopening is expected around early 2028, advertised as a notice on Find a Tender.
The tables above are a historical comparison map: which organisations in your lot cohort have broad or concentrated award evidence, how exact allocated value is distributed, and which buyers recur. They do not establish current preference or total spend.
The snapshot covers all 4,231 named published identities resolved to 4,210 organisation records: lots, size, region, confirmed award participations, valued-participation count, exact published GBP supplier allocations, distinct buyers, first and last confirmed award dates, and most frequent buyer.
