Microsoft details Kier Group's Copilot rollout across an 11,000-employee contractor

Kier Group builds schools, prisons and large water and nuclear projects from a base in Salford, England, and most of its workforce is not sitting at a desk. That shapes what a Copilot deployment can be. Microsoft’s account, published on 2 September 2026, describes a programme that began two years ago at the top of the company rather than on the sites, and a training format built around admitting you do not know the answer.

The company ran what it calls prompt-a-thons: small peer groups in which one team answered questions unaided while another answered the same questions with Copilot. Louisa Finlay, the chief operating officer, says some leaders held back because the technology was new and their diaries were full, and that she is content to be the person who asks the obvious question when a senior colleague would rather not. A separate exercise had Copilot read back six months of a leader’s mail, meeting documents and collaboration, name the film character it matched, then offer strengths, blind spots and advice for the year ahead.

The numbers

Kier employs roughly 11,000 people. About 40 percent of colleagues have Microsoft 365 Copilot; the remainder have Teams Premium, which adds AI features to Teams chat and meetings. Finlay works with Copilot inside Outlook, Excel, Teams and PowerPoint, using it to prioritise mail, run research and start a first draft of a job description.

What is still being built

The agent work is described as early. One agent is meant to gather and organise safety data so that the people supervising it can act on risk areas; another is being trained on Kier’s own safety standards and linked to site photographs, equipment records and the drone video the firm collects across its portfolio. Drones, Finlay says, reduce the need to work at height or near certain machinery. IT is building an agent to shorten response times while keeping a quick route to a human, with data held on Azure, and facilities management is next, predicting when parts such as pumps or lifts need servicing.

Finlay’s framing for all of it is “Human at the Helm”. She also argues the trade still needs graduates and apprentices who learn from the ground up and supervise the routine work an assistant now handles, which is the honest version of the productivity claim: the tool compresses the paperwork around a job, not the judgement of the person doing it.
