Incumbency is strong, not a lock
Grant Thornton's federal contractor survey watched incumbent recompete win rates fall from 75% to 54% in a single year. Incumbents lose to challengers who show up early, informed and specific.
BidSkim reads every UK award notice and works out when each contract comes back to market: the end date, the extension options, the incumbent who holds it and what it is worth. Then we reread each one to check it is the kind of work that genuinely returns to market, not a one-off. Right now that is 22,900+ contracts across 3,300+ public buyers due to expire within 12 months, with buyer contact details attached and ready to engage. The median is £192,000: SME-sized work, not megadeals. You see it months before the tender exists, while the terms are still being written.
The nearest recorded contract end dates in the corpus right now. Each one links to the full notice detail; the incumbent named below holds it today.
Recorded end dates from published award notices, framework agreements excluded, refreshed at least daily. An end date is a timing signal to verify and act on, not a guarantee of re-tender.
Counted from the award notices themselves, not estimated. Every figure below is a query against the corpus BidSkim reads each morning.
| Measure | Figure |
|---|---|
| Non-framework contracts expiring in the next 12 months | 22,916 |
| Public buyers holding them | 3,342 |
| Combined value, where a value is published | £44.3bn |
| Median contract value | £192,000 |
Counted on 6 August 2026 across 430,000+ UK award notices gathered from Find a Tender, Contracts Finder, Public Contracts Scotland and Sell2Wales, deduplicated across sources. Framework agreements are excluded, so these are contracts a supplier could bid for rather than routes to market.
Different markets, different methods, one direction of travel.
| Source | Figure | What it measured |
|---|---|---|
| Shipley Capture Guide | 40 to 80% | of customers have decided a preferred supplier before proposals are submitted |
| Stotles, government tender analysis | 46% | of won contracts were shaped, influenced or pursued before a formal tender was published |
| Open Contracting Partnership, Procurement Act year one | ~1 in 6 | above-threshold competitions received exactly one bid |
| 6sense, 3,500+ B2B buyers | 81% | of the time, the supplier a buyer engages first is the one that wins |
| European Court of Auditors, SR 28/2023 | 23.5% to 41.8% | growth in EU single-bid procedures between 2011 and 2021 |
Economists have measured the same effect inside procurement itself. A peer-reviewed study in Management Science found that where buyers have discretion, the firm they already know keeps winning, and a 2022 Review of Economic Studies paper on federal contracting is titled, simply, “Winning by Default”. By the day the notice goes live, the result is often already decided.
It is not a secret and it is not reserved for large companies. It is just slow to do by hand.
The UK public sector spent £249bn through procurement last financial year, and £24.7bn of it went directly to the government's own list of Strategic Suppliers. Those firms do not win by refreshing tender portals. They run capture: business development that starts 9 to 18 months before a tender is expected, tracking contract expiries, meeting buyers, answering every market engagement exercise. They also position early on the routes that shut competition out later, and win over half their contracts through frameworks, almost three times the rate SMEs manage.
Grant Thornton's federal contractor survey watched incumbent recompete win rates fall from 75% to 54% in a single year. Incumbents lose to challengers who show up early, informed and specific.
Tussell counts £41.7bn of Strategic Supplier contracts alone expiring before the end of this parliament. That is one slice of the market, and it is already larger than most sectors.
Talking to buyers early is not a grey area. It is official policy.
Section 16 of the Procurement Act 2023 spells out what preliminary market engagement is for: developing the buyer's requirements, preparing the tender documents and identifying likely contractual terms. In plain words, the suppliers in the room help decide what the tender asks for. Everyone else bids against a document they never saw coming.
The government does not merely permit this. It instructs buyers to do it. Cabinet Office guidance calls early engagement a particularly important tool for the achievement of value for money, and says publishing an engagement notice should be standard practice. Buyers listened: they published more than 600 preliminary market engagement notices a month in the Act's first year, topping 700 in February 2026, and tenders that follow early engagement attract 4.7 bids on average against 3.8 without it.
Buyers want more suppliers in early. Engagement happens months before the tender, so if the first you hear of a contract is the notice, that stage already happened without you. The full story of how the pre-tender window works is on our contract renewals page.
And what it is not.
A contract expiry tracker takes public award data and turns it into a forward-looking list: which contracts end when, who holds them now, and what they are worth. It is not a directory of live tenders. It is a view of what is coming, which is the only view early engagement can work from. Keyword alerts cannot do this job. They fire when a tender is published, which is precisely too late.
An award end date is not an opportunity.
Plenty of expiring contracts never come back to market in a form you could bid for. Some roll into a framework call-off. Some are extended without a new notice. Some services simply stop. Trackers that forward every end date fill your pipeline with dead leads and quietly train you to ignore them, and on most platforms, working out which expiries are genuinely winnable is a job left to you.
A renewal flagged 6 to 12 months out gives you what big bidders buy with headcount: time. BidSkim makes that time usable.
The incumbent, the value and the buyer, taken from the award notice rather than inferred.
The end date and the extension options, so you know whether you have six months or two years.
The pass/fail requirements that decide their bids, their spend history and their top suppliers.
Buyer contact details on 99.8% of tracked renewals. A first email you can send this morning, months before the specification is drafted.
BidSkim does not write bids. Bid-writing tools help after you decide to bid. BidSkim gets you into the conversation that decides what the bid will be. The full buyer picture is in how to research a public sector buyer.
This only works where the underlying data exists. Across the 430,000+ award notices we track, 73.2% publish a contract end date. The rest do not, and where the public record is thin, the tracker is thin too. Nobody publishes an official figure for how many expiring contracts are re-tendered rather than quietly extended; the Public Accounts Committee has criticised exactly that data gap. We would rather show you a shorter, honest list than pad it with guesses.
The same goes for the research above. Those numbers come from different markets and methods, and early engagement moves your odds rather than guaranteeing anything. What every source agrees on is direction: earlier is better, and the earliest reliable signal is the expiry of the contract you want.
