In a digital-first world, data privacy is no longer optional—it’s the law. The UK General Data Protection Regulation (UK GDPR) continues to set the standard for how organizations handle personal data. But for many businesses, especially SMEs, staying compliant can feel overwhelming.
That’s why we’ve put together this practical UK GDPR compliance checklist—to help you stay on the right side of regulation and earn your customers’ trust.
What Is the UK GDPR?
The UK GDPR governs how personal data must be processed in the United Kingdom. While it mirrors the EU GDPR in many ways, the UK version applies specifically to entities operating within the UK or processing data of UK residents.
Non-compliance can result in fines of up to £17.5 million or 4% of annual global turnover, so it pays to take it seriously.
