Power Automate in Practice: Top Use Cases for UK Enterprises
Power Automate is Microsoft's cloud-based workflow automation platform, included in most Microsoft 365 business licences. It connects Microsoft 365 apps — SharePoint, Teams, Outlook, Forms, and Dataverse — with hundreds of third-party services via pre-built connectors, enabling organisations to automate repetitive processes without writing code.
Where Power Automate Delivers Real Value
The use cases where Power Automate creates the most measurable impact in UK enterprises are approval workflows, document routing, notification automation, and system integration. Approval workflows — for purchase requests, HR processes, content sign-off, or contract execution — are a natural fit because Power Automate handles multi-stage approvals with conditional logic, automatic escalation, and a full audit trail, replacing email chains and shared spreadsheets.
Document routing and contract management are similarly well-suited. When a document reaches a certain status in SharePoint, Power Automate can trigger a sequence of conditions, route it for tier-one approval, escalate through multiple stages, notify the correct stakeholders at each step, and record the outcome — all without manual intervention. Integration of DocuSign and other e-signature platforms via Power Automate connectors further accelerates contract turnaround while maintaining compliance with digital signature standards.
Case Study: CalMac Ferries — Defect Management
CalMac is the UK's largest ferry operator, with more than 1,500 employees. The business needed a solution allowing vessel staff to log and manage defects across its entire fleet. ThinkShare built a defect management application using Power Apps and Power Automate, backed by a SharePoint data store.
The Defect Reporting Power App allowed vessel staff to log new defects via a conditional form that adapted to the type of defect being reported. Staff could search existing defects by vessel, apply multiple filters, and update records or submit extension requests. Power Automate handled the complex backend logic: updating records, routing notifications to the appropriate managers, and processing extension request approvals and rejections. All changes were captured in a dedicated audit table, accessible via a separate Power App for management oversight. The project ran to 70 days and is now into its second year of a support contract — demonstrating the long-term operational value of well-built Power Platform solutions.
Case Study: RigNet (Now Viasat) — Document Management System
RigNet, the world-leading networking provider for remote industrial operations, required a document management system that automated complex manual processes and tracked documents through an iterative client approval cycle. ThinkShare implemented the solution in SharePoint Online using document sets, metadata, and Power Automate to drive multi-stage approval workflows.
When a document was ready for client submission, the user triggered a Power Automate flow that validated all required metadata, routed to tier-one approval, escalated through tier-two and tier-three stages, and then delivered the document to the client. On return, tier-three users could upload the client's response, supersede previous versions, and set the document into one of five defined states — giving all stakeholders complete visibility of its position in the process. Following RigNet's acquisition by Viasat, ThinkShare also migrated the full solution to the Viasat Microsoft 365 tenant, demonstrating the portability of well-governed Power Platform implementations. The project ran to 60 days and is in its second year of a support contract.
The ROI Case for Power Automate
ThinkShare's ROI modelling for Power Automate projects consistently shows strong returns. For a team of ten employees each spending five minutes per day on a manual process that automation can eliminate, the annual time saving is approximately 216 hours. At average UK professional salary levels, that represents real financial value — before accounting for error reduction, faster cycle times, and improved compliance outcomes.
For contract management automation specifically, the reduction in turnaround time from days to hours has a direct impact on revenue cycles and client relationships. The key is identifying the right processes: high-frequency, rule-based, multi-step tasks with clear handoffs are where Power Automate delivers the fastest and most sustainable returns.
Getting Started with Power Automate
ThinkShare recommends beginning with a requirements gathering engagement to identify your highest-value automation opportunities before building anything. A well-scoped Power Automate project includes requirements gathering, flow build, testing with representative users, and project management throughout. Poorly scoped automations — built quickly without proper requirements analysis — frequently require rework and erode confidence in the platform. Contact ThinkShare at hello@thinkshare.co.uk to discuss your automation requirements and which use cases offer the fastest return in your specific context.
