Common dual-market strategies:
- CE marking only (during transition): Simplest route. CE mark is valid for NI (permanently) and GB (until 2028/2030 deadlines). Risk: GB deadline may not be extended.
- CE + UKCA dual marking: Most robust. CE from EU Notified Body for NI, UKCA from UK Approved Body for permanent GB access. Two conformity assessments required.
- CE + UKNI from UK Approved Body: UK Approved Body issues CE + UKNI marking for NI market. Combine with separate UKCA for GB. Note: UKNI not valid in EU.
