The Pensions Administration Standards Association (PASA) has published its 2025 edition of the Data Matching Convention (DMC) Guidance, ahead of the Citizen User Testing phase of the MoneyHelper pensions dashboard rollout by schemes and providers. Developed by PASA’s Dashboards Working Group in partnership with Lumera, the update reflects significant industry experience and developments since 2021 and addresses enhanced regulatory requirements. The guidance now provides a roadmap outlining robust frameworks for both ‘Match Made’ and ‘Possible Match’ criteria, incorporating verified data from the GOV.UK One Login service, including email addresses. Designed for administrators, connection technology providers, data controllers, and schemes with dashboard duties, it emphasises the use of multiple unique identifiers beyond National Insurance numbers, matching certainty standards, and targeted responses to prevent system overload. Additionally, it outlines procedures for monitoring matching performance, resolving discrepancies, and continuously improving data quality. PASA Chair David Fairs noted that ‘matching lies at the heart of the dashboards user experience’. This comprehensive update provides critical guidance for schemes and providers to fulfil their legal matching duties while protecting member data.
