The UK public sector's first generative AI contracts are reaching the end of their initial terms, part of a wider wave of AI and automation deals signed since 2023. Between July 2026 and June 2028, that pipeline comes up for renewal or re-competition. Renewal is the point where an incumbent's grip loosens, so suppliers who track expiry dates can engage buyers before the tender appears.
A Stotles analysis identified 87 UK public sector AI and automation contracts, all awarded from January 2023 onwards and worth £85.9m, set to expire between July 2026 and June 2028. The money is not spread evenly, automation makes up the largest share at £51.7m, ahead of AI in customer operations at £18.2m and generative AI at £16m. Grouped under one AI umbrella, this is the wave of contracts now reaching the end of its initial terms, with the newest generative AI deals hitting renewal for the first time.
Two quarters carry most of the value. Q3 2026 and Q4 2027 together account for £36.4m, or 42% of everything expiring in the window.
Yes, the earliest ones are landing now. In Q3 2026, £11.8m of the £14.4m expiring is generative AI from the 2023 and early-2024 buying wave reaching the end of its first term. These are among the first GenAI deals the public sector signed, and they now face a decision: extend, expand, or re-procure.
Later in the window, Q2 2028 gives the next signal. GenAI value returns to £3.3m alongside £8.8m of automation, this time from the 2025 and early-2026 deployment wave hitting its first renewal. Two separate GenAI cohorts reaching renewal inside the same pipeline is one of the clearest signs yet that public sector AI is moving from first-time buying into a repeatable renewal cycle.
Renewal is the one moment an incumbent's advantage weakens. By the time a tender is published, the requirement is usually shaped, the budget tested, and the incumbent well positioned. Stotles' 2026 Supplier Benchmark found incumbent advantage among the top reasons suppliers lose public sector bids. Expiry is the earlier signal. It tells you a re-procurement is coming quarters before the notice, while there is still room to influence it.
The automation cluster in Q4 2027 shows why timing pays. Almost the entire £22m expiring that quarter is automation, much of it robotic process automation and process automation from the 2024 and 2025 wave reaching end of term together. Buyers holding contracts at that scale, across local government, the NHS and blue light, tend to open wider technology consolidation conversations at renewal. Suppliers who see it coming can be in the room early.
Map the expiry dates, then work backwards. Waiting for the notice usually means arriving after the important decisions are made. Tracking expiries lets you start account research, incumbent analysis and buyer engagement while there is still time to shape the outcome.
A practical approach:
The nearest wave lands in Q3 2026, and a pipeline of AI and automation contracts continues to expire through to June 2028, based on Stotles data.
Automation, at £51.7m of the £85.9m identified, ahead of AI in customer operations at £18.2m and generative AI at £16m.
Expiry signals that a re-procurement is coming before the tender is published. That early window is when suppliers can engage buyers and challenge an incumbent's position.
Contract expiry dates, incumbents and buyer history are traceable through published procurement data. Platforms like Stotles bring these signals into a single view.
