Find the incumbent supplier on a UK public contract

Which portal depends on when the procurement began. Procurements started on or after 24 February 2025 run under the Procurement Act 2023 and publish every notice, above and below threshold, on Find a Tender, now the central digital platform. Procurements begun before that date stay on Contracts Finder, where the Awarded contract filter under Procurement stage narrows the search to awards. For any contract more than a year or two old, Contracts Finder is where the incumbent was named.

Search by the authority's name plus the service, or by CPV code. The contract award notice names the winning supplier and the contract value. Record the procurement reference: it is the identifier that links the award to every later notice on the same contract.

Scottish, Welsh and Northern Irish buyers publish on their own portals — Public Contracts Scotland, Sell2Wales and eTendersNI. Scottish procurement runs under its own regime rather than the Procurement Act 2023, so a Scottish council's awards are on Public Contracts Scotland and nowhere else.

Under the Procurement Act 2023 each contract generates a sequence of notices, and each one tells you something different about the incumbent.

The latest notice wins. A contract details, change or termination notice takes precedence over the award notice that preceded it, so search the procurement reference for later notices before treating an award as current.

Most councils, NHS trusts and central departments publish a contract register: a spreadsheet of every live contract with supplier, value, start and end dates, extension options and procurement reference. English local authorities must publish one for every contract over £5,000 under the Local Government Transparency Code 2015. It usually sits under the transparency or procurement pages of the authority's website, and a search for the authority's name with "contract register" finds it faster than navigating.

The register is often the quickest route to the current holder, because it reflects extensions and framework call-offs that never produced a standalone notice. It is also often stale, so treat its dates as a lead to confirm against the notice trail, not as the answer.

Central government departments publish every payment over £25,000, and English local authorities every payment over £500, as monthly or quarterly CSV files on their own websites and on data.gov.uk. Filter for the service area or cost centre and look for a vendor receiving payments of a similar size every month or quarter. The recurring payee is usually the incumbent, and the payment size gives a rough annual value.

Spend data catches contracts bought under a framework call-off or a direct award that left a thin notice trail, and it is the only public source that shows a relationship is live rather than merely awarded.

If the record is still unclear, a request under the Freedom of Information Act 2000 obliges the authority to respond within 20 working days. Ask for a record that already exists rather than for a judgement, because a request for an existing document is harder to refuse and faster to answer.

Commercially sensitive detail such as pricing can be withheld under section 43 of the Act, but the supplier's name, the dates and the headline value rarely are, and an authority cannot withhold a whole register because part of it is sensitive.

The supplier named at award is not always the incumbent. Contracts get extended, novated to a different legal entity after a merger, or terminated early, and each of those leaves the original award notice looking current when it is not.

A framework supplier is not the incumbent either. A framework award appoints several suppliers; the buyer relationship is created by the call-off. Under the Procurement Act 2023 each call-off gets its own contract award and contract details notices, which name the framework and how the call-off was awarded. Search for the call-off, not the framework.

Example: a Crown Commercial Service framework has eight appointed suppliers. Department X buys through it, and Company Y wins the call-off. Company Y is the incumbent for Department X's requirement. The other seven have no relationship with that buyer at all.

Whichever source answered the question, capture the same fields, so that lookups across buyers can be compared and the recompete date can be forecast rather than guessed.

Incumbency is not the same as safety. Repeated short extensions rather than a clean recompete, performance concerns in the authority's committee papers and board minutes, National Audit Office findings, a poor result on a contract performance notice, or FOI responses about the contract all mean the requirement is in play.

An incumbent with a long, clean tenure, a satisfied buyer and no adverse findings is expensive to displace. That is a legitimate no-bid, and knowing it early saves the cost of a full response. The purpose of incumbent research is not to find a reason to bid. It is to spend bid capacity on the contests you can win.
