Data Privacy Compliance: US and UK Laws and a Practical Checklist
Data privacy compliance is the practice of following the laws that govern how an organization collects, uses, stores, shares and deletes personal data. In the US, that means state privacy laws plus sector rules such as HIPAA and GLBA. In the UK, it means UK GDPR, the Data Protection Act 2018 and recent reforms.
What Is Data Privacy Compliance?
Compliance means showing, not just claiming, that you handle personal data lawfully. That includes knowing what data you hold, having a legal reason to use it, telling people how it is used, honoring their rights, keeping it secure and reporting breaches on time.
What Is Data Privacy? (Data Privacy Definition)
Data privacy is a person’s right to control how information about them is collected and used. Personal data, often called personally identifiable information (PII) in the US, includes names, contact details, ID numbers, location data, online identifiers and health or financial records.
Data Privacy vs Data Security vs Data Compliance
Privacy is about whether and how data should be used. Security is about protecting it from unauthorized access. Compliance is proving you meet the legal rules for both. A business can have strong security and still break privacy law, for example by using customer data for a purpose it never disclosed.
Why Privacy Compliance Matters for Businesses
Fines, Lawsuits and Breach Costs
Under UK GDPR, the most serious infringements can bring fines of up to £17.5 million or 4% of global annual turnover, whichever is higher. US state privacy laws are enforced mainly by attorneys general: Indiana and Kentucky law, for example, allow up to $7,500 per violation, and Rhode Island up to $10,000. California’s law also gives consumers a private right of action for certain data breaches.
Customer Trust, Contracts and Cyber Insurance
Larger customers increasingly ask suppliers to prove privacy and security controls before signing. Cyber insurers ask similar questions at renewal. Weak answers can cost contracts or raise premiums.
Core Principles Behind Every Privacy Law
Most laws share the same principles, set out in UK GDPR and mirrored in US state laws:
- Lawfulness, fairness and transparency: tell people what you do with their data
- Purpose limitation: use data only for the stated purpose
- Data minimization: collect only what you need
- Accuracy: keep data correct and up to date
- Storage limitation: delete data when no longer needed
- Security: protect data with appropriate controls
- Accountability: document decisions and be able to prove compliance
US Data Privacy Laws and Rules
CCPA and CPRA (California)
The California Consumer Privacy Act took effect on January 1, 2020, and was expanded by the California Privacy Rights Act from January 1, 2023. It gives Californians rights to know, delete, correct and opt out of the sale or sharing of their personal information. It is enforced by the California Privacy Protection Agency and the Attorney General.
Other State Privacy Laws (Virginia, Colorado, Texas and More)
Virginia’s law took effect January 1, 2023, Colorado’s July 1, 2023, and Texas’s July 1, 2024. Indiana, Kentucky and Rhode Island laws took effect on January 1, 2026, according to each state’s legislature and attorney general. Thresholds vary: Indiana and Kentucky apply to businesses processing data of 100,000 state residents, or 25,000 if more than half of revenue comes from selling data, while Rhode Island’s threshold is 35,000 residents. Check each state where you have customers.
HIPAA for Health Data
HIPAA’s Privacy, Security and Breach Notification Rules cover health providers, health plans, clearinghouses and their business associates. Breaches of unsecured health information must be reported to affected individuals without unreasonable delay and no later than 60 days after discovery.
GLBA and the FTC Safeguards Rule for Financial Data
The Gramm-Leach-Bliley Act covers financial institutions, a broad term that includes many lenders, tax preparers and some dealers. The FTC’s amended Safeguards Rule requires a written information security program, and since May 2024 covered businesses must notify the FTC of certain breaches affecting 500 or more consumers.
COPPA, the FTC Act and State Breach Notification Laws
COPPA restricts collecting data from children under 13 online. Section 5 of the FTC Act lets the FTC act against unfair or deceptive data practices. All 50 states have breach notification laws with their own deadlines and definitions.
UK Data Privacy Laws: UK GDPR and the Data Protection Act 2018
Key UK GDPR Requirements and ICO Enforcement
UK GDPR requires a lawful basis for processing, clear privacy notices, records of processing, data protection impact assessments for high-risk processing, and reporting of qualifying breaches to the ICO within 72 hours. The ICO is the regulator.
Data (Use and Access) Act 2025 Changes
The Data (Use and Access) Act 2025 received Royal Assent on June 19, 2025, and is now fully in force. Most data protection changes started on February 5, 2026, including simpler rules in some areas, new ICO investigation powers, and PECR fines raised to the UK GDPR level of £17.5 million or 4% of global turnover. Since June 19, 2026, every organization must offer a way to make data protection complaints, acknowledge them within 30 days and respond without undue delay.
Working With EU Customers (EU GDPR)
If you offer goods or services to people in the EU or monitor their behavior, EU GDPR can apply too, even without an EU office. UK and EU rules are close but now differ in places, so check both.
Which Privacy Law Applies to Your Business?
Ask four questions:
- Where are your customers or users? Each state, the UK and the EU have their own rules.
- What data do you hold? Health, financial, children’s and biometric data trigger extra laws.
- How much data? US state laws use resident and revenue thresholds.
- What sector are you in? Healthcare, finance and education have specific rules.
Breach notification laws, the FTC Act and UK GDPR apply regardless of size.
How to Meet Data Privacy Compliance: A Step-by-Step Checklist
Map and Classify the Personal Data You Hold
List what personal data you collect, where it is stored, who can access it and who you share it with. You cannot protect or disclose what you have not mapped.
Set a Lawful Basis, Notices and Consent
Record the legal reason for each use, publish a clear privacy notice and collect consent where required, such as for marketing cookies.
Handle Data Subject and Consumer Rights Requests
Set up a process to verify identity and respond to access, deletion, correction and opt-out requests within legal deadlines. Add a complaints route for UK requirements.
Secure Data With Access Controls, Encryption and DLP
Limit access by role, enforce MFA, encrypt sensitive data and monitor for leaks.
Manage Vendors and Cross-Border Transfers
Sign data processing agreements, check vendors’ security and use approved transfer mechanisms for international data flows.
Prepare for Breach Notification
Write an incident plan with US state, HIPAA, FTC and ICO deadlines, and rehearse it.
Train Staff and Audit Regularly
Train staff on handling personal data and review compliance at least yearly.
Privacy Frameworks and Tools (NIST Privacy Framework, ISO 27701)
The NIST Privacy Framework gives a voluntary structure for managing privacy risk and pairs with the NIST Cybersecurity Framework. ISO/IEC 27701 extends an ISO 27001 security management system to privacy and can be certified. Privacy management software helps with data mapping, consent and request handling.
Data Privacy Compliance in Short: Key Takeaways
Data privacy compliance comes down to knowing your data, using it only for stated purposes, respecting people’s rights, securing it and reporting problems quickly. Laws keep changing: three US states added laws in 2026, and UK reforms are now in force. To review where your business stands, contact Cyber Security Solutions Ltd through our contact page.
FAQs
The US has no single national privacy law. Key rules include broad state privacy laws such as California's CCPA/CPRA, Virginia, Colorado and Texas, plus sector laws: HIPAA for health data, GLBA for financial data and COPPA for children's data. The FTC Act and all 50 state breach notification laws also apply.
It can. UK GDPR applies to organizations outside the UK that offer goods or services to people in the UK or monitor their behavior there. A US online store selling to UK customers may need to comply and appoint a UK representative. Check the ICO's guidance on territorial scope for your situation.
There is no broad federal privacy law covering all businesses. Instead, federal laws cover specific sectors and data types, such as HIPAA, GLBA and COPPA, while the FTC polices unfair or deceptive practices. States have filled the gap with their own broad privacy laws, which differ in thresholds and details.
Consequences include regulator investigations, fines, enforcement orders, lawsuits in some cases and reputational damage. UK GDPR fines can reach £17.5 million or 4% of global turnover. US state attorneys general can seek civil penalties per violation. Customers and partners may also end contracts if privacy failures come to light.
Yes, though which laws apply varies. UK GDPR applies to almost every business handling personal data, regardless of size. Many US state laws apply only above set thresholds, but breach notification laws, HIPAA, GLBA and the FTC Act can apply to small businesses. Basic data mapping and security are always worthwhile.
The terms overlap. In the US, "data privacy" usually describes rights and rules about how personal data is used. In the UK and EU, "data protection" is the legal term covering those same rules, including security duties. Both aim to keep personal data used fairly, lawfully and safely.
