GDPR & Data Residency

Kantar / TNS is UK-based. The European Commission renewed its adequacy decision for the UK under GDPR in December 2025, meaning data transfers to the UK are currently treated similarly to intra-EU transfers. Adequacy decisions are time-limited and reviewed periodically, so verify the current status before relying on it for new contracts.
