How big a buyer is Wandsworth?
Wandsworth is a serious spender. Our data covers £3.9 billion in recorded spend across nearly 257,000 payment transactions, with payment data running from January 2019 and contract records spanning 2014 to 2026. For a London borough of around 330,000 people packed into 13.1 square miles, that is a hefty procurement operation. The contract data we hold captures 95 published contracts worth a combined £41.1 million, alongside 127 tenders valued at £345.8 million. That tender pipeline is worth paying attention to. It tells you there is a steady flow of upcoming work being advertised, and the gap between current contract value and tender value suggests a council actively going to market. Across the spending records we hold, the sheer volume of transactions points to a council that processes a lot of smaller payments too, not just big-ticket contracts. If you are looking at London boroughs, Wandsworth moves serious money.
Construction and care dominate, but nobody owns this market
Of the 5,557 identified suppliers in our dataset, no single company has a stranglehold. The HHI score sits at just 77, which is very low, and the top five suppliers account for only 13.6% of recorded spend. That is unusually spread out. Construction firms take the biggest slice at 18.4% of matched spend (£419 million), with Wates Construction, F M Conway, Hill Partnerships, and Willmott Dixon all featuring in the top ten. Health and social care runs close behind at 17.8% (£405 million), drawing on 715 suppliers. The top individual supplier is Winstanley and York Road Regeneration LLP at £84.6 million, which looks like a specific housing regeneration vehicle rather than a general contractor. Transport Trading Limited and Serco follow at £65.2 million and £62.1 million respectively. Professional services, education, and admin support each sit in the 7-8% range, so there is breadth across multiple sectors here.
Open competition or direct award: what does the split look like?
Based on the 27 contracts we have procurement method data for, 17 went through open tender and 10 were direct awards. That is roughly a 63/37 split in favour of competitive routes, which leans more open than you might expect. The median contract value sits at £530,112, so most of the tracked contracts are mid-range rather than massive. Of these 27 contracts, 21 were above the procurement threshold and six fell below it. The tender pipeline of 127 notices worth £345.8 million gives you a decent forward view of what is coming to market. Wandsworth sources its data through Find a Tender and its own council website, and our collection runs up to December 2025. One thing worth noting: the contract dataset is a small window into a much larger spend base. Those 257,000 payment transactions tell you the council buys from a very wide supplier base day to day, even if only a fraction appears in formal contract notices.
