Telefonica Tech UK Ltd

Markel, a global insurance provider with over 5,000 employees, replaced its legacy helpdesk system with Dynamics 365 Customer Service, implemented by Telefónica Tech. The new solution integrates with key systems like Cisco and Calabrio, provides a 360-degree view of the customer, and handles 750 calls per day—up to 2,500 during the Covid pandemic—while migrating 7 years of historical data with zero disruption to customer service. Telefónica Tech's delivery enabled Markel to improve efficiency, gain deeper insights, and future-proof its customer service operations.

Telefónica Tech Business Applications implemented a Microsoft Power Platform solution for UK consumer champion Which?, saving 150 hours per month on administrative tasks and centralising test data for 4,600 products annually. Power Apps and Azure Data Factory automated data capture from 250-1,000 measurements per product, reducing manual errors and replacing thousands of spreadsheets with a single source of truth. The enterprise-level solution, integrated with Dataverse and a CMS, delivers real-time visibility across 150+ product categories, enabling Which? to scale its independent product testing and maintain its reputation for accuracy.

Telefónica Tech, Starlight Consulting, and Oxford University Hospitals NHS Foundation Trust co-designed and delivered the Thames Valley & Surrey Secure Data Environment (TVS SDE) on Microsoft Azure Databricks, processing over 30 billion health records from more than 25 source systems to support a population of 4.3 million. The platform enabled more than 35 live research projects and over 100 approved researchers by replacing cumbersome multi-organisation approval processes with a single robust governance framework that includes public oversight. Within six weeks, Telefónica Tech stood up the initial environment using its Data Platform Accelerator Framework for healthcare, establishing a Trusted Research Environment that keeps NHS data securely stored on-premises while allowing de-identified data access for cancer, cardiovascular, and mental health research.
