The problem
UK Power Networks delivers electricity to 8.5 million homes and businesses and employs about 6,500 people. Its teams handle contracts, supplier emails, customer complaints and reports every day. The company wanted to cut the time spent on this routine work and give staff more time for tasks that need judgment.
What they built
The company gave staff Microsoft 365 Copilot, an AI assistant built into everyday office tools such as email, documents and spreadsheets. Microsoft's story describes uses in procurement, such as contract reviews, supplier emails and spending-trend reports, and in customer service, such as prioritising outstanding complaints and warmer communications. Teams also used it to build reports in SharePoint, the company's document store.
How they did it
The CEO and Executive Management Team approved a trial, and a Copilot Task Force ran it. The task force interviewed teams to understand their needs and listed close to 50 use cases. In January 2024 the company started with 300 licences, and it grew to 1,000 by the end of the pilot in December 2024.
Training was kept in small groups, and 12 Copilot Champions helped colleagues. Workshops reached more than 950 people. Support has continued since, with daily nudges and tips, lunch-and-learn sessions and competitions.
Results
Since the roll-out, the company reports 96% adoption across the business and a 480% return on investment. Microsoft's story also says freed-up staff can focus on more strategic activities and quotes a measurable impact on employee satisfaction and engagement, without giving numbers.
The sources do not say how adoption or ROI was calculated, what the licences cost, or how many hours were saved.
What to copy
Run a structured pilot: interview teams first, pick concrete use cases, train in small groups, and appoint champions. Agree how you will measure adoption and return before the pilot starts, so your numbers can be checked.
Lessons for your project
Find the use cases before widening licences. The task force held nearly 40 interviews with teams and listed close to 50 use cases, which gave staff concrete reasons to try the tool.
Start with a small first wave. The company began with 300 licences and widened to 1,000 by the end of the pilot in December 2024.
Use peer champions and small training groups. The company capped sessions at 20 to 30 people and named 12 champions to help colleagues day to day.
Keep nudging after launch. Daily tips, lunch-and-learn sessions and competitions kept the tool in front of staff.
Define the ROI calculation before you quote it. The source gives no method, so readers cannot compare the 480% with their own business case.
Caveats
- All figures come from UK Power Networks as relayed in Microsoft's own story. The 96% adoption (no denominator is given, so it may cover only licence holders) and 480% ROI are not independently verified, and neither the adoption definition nor the ROI calculation is explained.
- The second source, a trade news article, repeats the Microsoft announcement and adds no independent check of the figures.
- No licence cost, hours saved or team size is stated. The ROI cannot be reproduced from the published information.
- Microsoft calls the 2024 phase both a pilot and a roll-out of 1,000 licences, and does not say when the adoption and ROI figures were measured or whether licences went beyond 1,000 afterwards. Support activities are described as continuing.
- Microsoft's story also mentions other AI uses at the company, such as generative AI in Azure OpenAI Service for incoming email. The reported figures relate to the Copilot rollout.
