Overview
Northern Ireland's unique position within the UK medical device regulatory landscape — why EU MDR and EU IVDR apply in NI, what this means for manufacturers, and where to find more information.
Why Northern Ireland has a different regulatory regime
Northern Ireland occupies a unique position in the UK medical device regulatory landscape. While Great Britain (England, Scotland, and Wales) operates under UK MDR 2002 and UKCA marking, Northern Ireland remains aligned with EU single market rules for goods — including medical devices.
This means:
- EU MDR 2017/745 applies to general medical devices placed on the NI market
- EU IVDR 2017/746 applies to IVD medical devices placed on the NI market
- CE marking is required for devices on the NI market
- EU Notified Bodies must be used for third-party conformity assessment for the NI market
This alignment was established by the Northern Ireland Protocol (now the Windsor Framework) as part of the UK's withdrawal from the EU, to preserve the frictionless goods flow across the Ireland/NI land border.
MHRA's dual role in Northern Ireland
MHRA acts as the competent authority for Northern Ireland — but in an EU regulatory context. For NI:
- MHRA receives and processes vigilance reports under EU MDR/IVDR rules
- MHRA participates in EU regulatory processes affecting NI
- MHRA works with EU institutions on NI-specific issues
