A £328 million buyer in Tees Valley, but how active?
Darlington Borough Council is a unitary authority covering about 107,000 people across 76 square miles in the North East. Our dataset holds £328.6 million in recorded spend spread over nearly 48,000 transactions, drawn from 25 source files and collected from three publishing domains including Find a Tender. That data runs from 2017 to 2026, giving you a decent window into spending patterns. On the contracts side, we've tracked 126 published contracts worth a combined £8.9 million. Tenders tell a different story: 129 published opportunities valued at £130 million. Across those transactions, we've matched 1,401 supplier records to 1,327 unique identified suppliers. For a borough council of this size, that's a broad supplier base. Darlington sits within the Tees Valley Combined Authority, so some spending may flow through TVCA frameworks rather than appearing in the council's own records.
Construction and care dominate, but nobody owns this market
Two sectors account for over half the matched spend. Construction leads at 26.9%, with £47.8 million across 111 identified suppliers. Willmott Dixon tops the supplier list at £24.4 million, and Kajima Darlington Schools sits second at £9 million. Health and social work runs close behind at 24.6%, pulling in £43.7 million from 123 suppliers. That sector features several care providers in the top ten, including Making Space, Brighter Horizon Homes, and Dimensions Personalised Support. Beyond those two, spending fragments quickly. Education takes 7%, professional services and IT each sit at 5%, and everything else falls below that. The concentration numbers back this up: an HHI of 295, which is very low, and the top five suppliers account for just 28.7% of matched spend. If you're looking at Darlington, this is a market where spending is spread widely rather than locked up with a handful of incumbents.
Where are the open tenders?
This is where the data gets interesting. Our procurement records show just 3 above-threshold contracts, all awarded directly. The median contract value among those three is £3.3 million. Zero contracts came through open competition in the records we hold. But before drawing firm conclusions, consider the context. Darlington has published 129 tenders worth £130 million on Find a Tender, which points to competitive procurement happening at the opportunity stage. The contract award data we hold simply may not capture the full picture of how those tenders resolved. With 1,327 identified suppliers across the spending records, it's clear the council works with a wide range of providers in practice. For bid managers, the tender pipeline is where you'll find the action. Those 129 published opportunities across the dataset period suggest Darlington does go to market regularly, even if the contract records we've captured are sparse.
