  • Over the last 10 years, we successfully defended over 81% of medical claims, making no compensation payments
  • Over 98% of calls to medico-legal advisers connected straight away during normal working hours
  • 80% of GMC cases the MDU advisory department assisted with that closed in 2025, did so with no sanction or adverse finding by the GMC
  • Over the last 5 years we have supported nearly 1200 members with GMC investigations
  • In 2025, our award-winning membership team answered more than 105,000 calls with over 80% answered within 20 seconds
  • Almost 700 seminars delivered to groups of doctors across the country in 2025
  • On a five-year comparison (2020 to 2024), the MPTS average outcomes were that only 26% of cases were concluded with no finding of impairment. Happily, the MDU’s solicitors’ positive outcomes were significantly better for the same period, at 52%.
