Contract Expiry Dates: How to Find When a Council Contract Ends

Every public contract in Britain carries an expiry date, and almost every supplier ignores it. That is not a small oversight. It is the difference between finding out about a tender when it publishes, with three weeks to respond, and knowing eighteen months in advance that Kent County Council's cleaning contract ends on 30 April 2027 and Birkin Cleaning Services currently holds it.

Both of those facts are public record. This guide shows you exactly where council contract end dates live, how to read them, and what to do with the runway they give you.

Where are council contract end dates published?

When a public body awards a contract, it must publish an award notice. On Contracts Finder, the notice for every awarded contract includes a contract period: a start date and an end date. On Find a Tender, above threshold awards carry the same information inside the contract period fields of the OCDS release.

That is the whole secret. The data sits in the award notice, the document most suppliers close the moment they see someone else's name on it.

Read that table again. It is a diary of future tenders with the current winner named on each line.

When does a contract get retendered?

An end date is not automatically a tender date, and pretending otherwise will burn you. Three things can happen when a contract approaches expiry.

• Retender. The default. The buyer runs a new competition, typically publishing the notice three to nine months before expiry so the new supplier can mobilise.
• Extension. Most contracts include extension options, often written as 3+1+1: a three year base with two single year options. A buyer who is happy with the incumbent frequently extends. The original notice usually states the maximum term, so you can work out how much extension road is left.
• Insourcing or aggregation. Occasionally the service comes in house, or gets bundled into a bigger lot or framework call-off. Painful, but visible early if you are talking to the buyer.

The practical rule: treat the end date as the centre of a window, not a firm date. A contract ending April 2027 means procurement activity between roughly July 2026 and January 2027. Which is why the time to act on it is now, not next spring.

How do you find contract end dates on Contracts Finder?

Step by step, no tools required.

• Search Contracts Finder for your service keyword, then filter notice type to Awarded.
• Open each award notice and find the contract period fields, listed as start date and end date alongside the awarded value and supplier name.
• Record buyer, service, value, incumbent, and end date in a spreadsheet.
• Sort by end date. Everything inside the next eighteen months is your pipeline.
• Repeat monthly, because awards publish continuously.

Honest warning about the manual route: it does not scale. A single sector produces hundreds of award notices a year. The facilities desk alone tracked 277 awarded contracts worth £3.91 billion in the last twelve months. Reading every award notice by hand is a part time job, which is precisely why we built the Renewal Radar into every AtlasRevenue desk: it reads the contract periods for you and lists what expires inside twelve months, incumbent included, soonest first.

What should you do before a contract expires?

Runway is only worth something if you use it. Working back from an expected retender, in ninety day blocks.

Twelve to nine months before expiry

Introduce yourself to the service owner, not the procurement team. One page, three case studies, one question about how the current service is performing. You are not selling. You are becoming a name they recognise when the options appraisal starts. Our guide to pre-tender engagement covers the rules of this conversation.

Nine to six months before expiry

Watch for the signals that a retender is coming rather than an extension: soft market testing, an RFI, a market engagement notice, or budget line items in committee papers. Respond to every one. Under the Procurement Act 2023, buyers who run preliminary market engagement must publish a notice saying so, which conveniently confirms the tender for you.

Six to three months before expiry

Build the bid before the bid. Case studies matched to the specification you expect. TUPE questions drafted, because in service contracts the incumbent's staff usually transfer and TUPE pricing sinks unprepared bidders. Accreditations current. References warm.

Three months to publication

The notice lands. You are assembling, not writing. Bidders who start at the notice compete against people who started nine months earlier. Now you are one of the nine month people.

Does incumbency actually matter?

Less than folklore says. Incumbents lose retenders constantly, for boring reasons: complacent pricing, tired service, a specification rewritten around problems the buyer stopped tolerating. What incumbents genuinely have is information, the performance data and relationship you lack. Pre-expiry engagement is how you close that gap. Knowing the incumbent's name, which the award notice hands you, also tells you exactly who you are pricing against. We wrote a full method for that in how to find the incumbent supplier.

Frequently asked questions

Are contract end dates always published?

On awarded notices, overwhelmingly yes for Contracts Finder listings, and above threshold awards on Find a Tender carry contract periods in their OCDS data. Quality varies. Some notices omit or fudge the end date, and extensions exercised later do not always generate a fresh notice. Treat end dates as high quality signals, not certainties.

How far in advance should I contact a buyer before their contract ends?

Nine to twelve months is the sweet spot. Early enough to be part of the thinking, late enough that the service owner is starting to think about it. Under three months, the specification is usually locked and you are just another bidder.

What does 3+1+1 mean on a contract notice?

A three year base term with two optional one year extensions, exercised at the buyer's discretion. Maximum five years. If the notice was awarded in 2023 as 3+1+1 and the base ends in 2026, the buyer may extend to 2027 or 2028 before retendering. Factor the options into your window.

Can I ask a council when a contract will be retendered?

Yes, and you can go further: submit a Freedom of Information request for the contract end date, extension options, and current spend if the notice is unclear. Councils answer these routinely. A polite direct question to the service owner often gets the same answer faster.

Is there a tool that tracks contract expiry dates automatically?

AtlasRevenue's Renewal Radar does exactly this. Every sector desk lists awarded contracts entering their retender window inside the next twelve months, with buyer, value, incumbent, and days remaining. It is on every desk page, and the same data feeds our buyer scans.
