How does the Square Mile spend nearly a billion pounds?
The City of London Corporation is unlike any other council. It covers just 1.2 square miles and has a resident population under 11,000, but it functions as the local authority for one of the world's busiest financial districts. Our data covers £921 million in recorded spend across 90,315 transactions from 2023 to 2026, drawn from 36 source files. That is a staggering amount of purchasing for such a small geographic footprint, but it makes sense when you consider the Corporation's dual role managing both local services and the Square Mile's infrastructure. We've also tracked 144 tenders worth a combined £984 million. The spending records come from cityoflondon.gov.uk and Find a Tender, collected through to November 2025. For a body with fewer than 11,000 residents, the per-capita spend figure would look absurd. But the Corporation is not really a population-serving council in the usual sense, and the data reflects that.
Construction dominates, but who's actually getting paid?
Across the 5,270 suppliers we've matched to company records, the top five account for 51.5% of recorded spend. The Freud Museum London sits at number one with £213 million, followed closely by Mace Limited at £204 million. That top-two concentration is striking. But the broader market is unconcentrated, with an HHI of 759 and 2,992 identified suppliers in total. Construction is the largest sector by spend at £373 million, or 30.9% of the total, spread across 157 suppliers. Education follows at 18.3%, though that figure is heavily driven by a single supplier. Wholesale and retail trade and admin services each sit around 9%. If you're in professional or technical services, that sector has the highest supplier count at 477 firms but takes just 3.9% of spend, which tells you the average contract value is relatively modest. Health and social work accounts for 5.4%, with Preventx Limited pulling in £53 million of that.
What does the tender pipeline look like?
Our dataset includes 76 contracts and 144 tenders for the City of London Corporation. The contract records we hold don't include procurement method breakdowns, so we can't tell you what proportion went through open competition versus direct award. That is a gap in the published data rather than a gap in our coverage. What we can say is that the tender pipeline is active. At £984 million across 144 published opportunities, the average tender value sits around £6.8 million, which points to a council that packages work into sizeable lots. Given the construction-heavy spending profile, many of those larger tenders likely relate to capital projects and infrastructure in the Square Mile. The Corporation publishes through both its own site and Find a Tender, which means opportunities are visible through standard procurement channels. With nearly 3,000 suppliers already in the mix, competition for work here appears broad based on what the data shows.
