£2.4 billion and counting: how big a buyer is Islington?

For a borough covering just 5.8 square miles, Islington moves serious money. Our data shows £2.4 billion in recorded spend across 293,884 transactions, drawn from 52 source files spanning 2003 to 2026. That is a deep dataset. We have tracked 5,079 published contracts worth a combined £8.9 million in stated contract value, plus 242 tenders valued at £364 million. The gap between those two figures is worth noting. Contract values in the published records look low relative to what the payment data shows is actually flowing through, though the reasons behind that discrepancy are not clear from the data alone. The transaction volume shows Islington has a long purchasing history in the data we hold, with nearly 294,000 individual payment records giving a detailed view of where the council directs its spending over time.

Admin services and real estate dominate, but competition is wide open

Four of the top five suppliers by recorded spend sit in administrative and support services. Matrix SCM, Mears, Transform Islington, and Specialist Recruitment Services account for a combined £645 million between them. Partners for Improvement in Islington leads the pack at £260 million, classified under real estate. Together, admin services (28.2% of matched spend) and real estate (12.9%) make up over 40% of what we have tracked. Health and social work follows at 11.6%, with construction close behind at 10.5%. Despite those large names at the top, the market is not concentrated. An HHI of 267 is classified as unconcentrated, and the top five suppliers account for only 31.9% of spend. Across the 12,298 supplier records we have matched, there are 5,365 identified suppliers operating across 22 sectors.

How does Islington actually buy things?

We have tracked two contracts with procurement method data, both direct awards sitting above threshold. The median contract value across those records is £4.4 million. That is a small sample, so it may not be representative of the council's broader procurement approach. The tender record is more extensive. With 242 tenders worth £364 million on record, there is clearly procurement activity happening beyond what the contract-level records capture. Islington is also a member of two purchasing consortiums: Procure Plus Holdings and the South East Consortium. Both consortiums may provide additional procurement routes. The tender feed provides the most detailed view of procurement activity on record for this council. The payment transaction data, with nearly 294,000 records, gives the fullest picture of where money actually goes across the borough's supplier base.
