GDPR Compliance for Employee Health Screening: Essential Guide

Employee health screening generates sensitive personal data — and under GDPR, mishandling this information can result in fines of up to €20 million or 4% of annual turnover.

Here's your essential guide to GDPR-compliant health screening that protects both your business and your employees' privacy rights.


Why GDPR Matters for Health Screening

Health data is classified as "special category personal data" under GDPR, requiring:

  • Explicit consent from employees
  • Heightened security measures
  • Clear data retention policies
  • Transparent processing purposes

The stakes: Non-compliance can result in:

  • Substantial financial penalties
  • Reputational damage
  • Employee trust erosion
  • Legal action from data subjects

Legal Basis for Processing Health Data

You need a valid legal basis under Article 6 AND Article 9 of GDPR:

Article 6 (General Processing):

  • Legitimate interests (most common for workplace screening)
  • Legal obligation (industry-specific requirements)
  • Vital interests (emergency health situations)

Article 9 (Special Category Data):

  • Explicit consent from the employee
  • Employment law obligations
  • Protecting vital interests (if consent impossible)
  • Occupational medicine purposes

Getting Valid Consent

Consent must be:

  • Specific — tied to particular screening activities
  • Informed — employees understand what data is collected and why
  • Freely given — no coercion or employment consequences
  • Withdrawable — employees can opt out without penalty

Example consent language:

"I consent to CheckAtWork collecting and processing my health data for the purpose of assessing my fitness for work. I understand this includes [specific tests] and that results will be shared with [specific parties]. I can withdraw this consent at any time."


Data Minimisation in Practice

Only collect what you actually need:

✅ Justified for office workers:

  • Basic health questionnaire
  • Blood pressure and BMI
  • Vision screening (if computer work)

❌ Excessive for office workers:

  • Detailed blood panels
  • Genetic testing
  • Mental health assessments (unless job-specific risk)

✅ Justified for construction workers:

  • Lung function tests
  • Hearing assessments
  • Physical capability evaluations
  • Drug and alcohol screening

Secure Data Storage Requirements

Technical measures:

  • Encryption at rest and in transit
  • Access controls and user authentication
  • Regular security updates and patches
  • Secure backup and recovery procedures

Organisational measures:

  • Staff training on data protection
  • Clear data handling procedures
  • Regular security audits
  • Incident response plans

Retention periods:

  • Keep only as long as necessary
  • Typical retention: 3-7 years post-employment
  • Some industries may require longer (aviation, nuclear)
  • Regular review and secure deletion

Employee Rights Under GDPR

Employees can request:

  • Access — copies of their health data
  • Rectification — correction of inaccurate data
  • Erasure — deletion in certain circumstances
  • Portability — transfer of data to another provider
  • Restriction — limitation of processing activities

Response timeframes:

  • 1 month for most requests
  • Extensions possible for complex requests
  • Free of charge (unless clearly excessive)

Third-Party Provider Requirements

When choosing a health screening provider, ensure:

  • They have robust GDPR policies
  • Data Processing Agreements (DPAs) are in place
  • Security certifications (ISO 27001, Cyber Essentials)
  • Clear data breach notification procedures
  • UK/EU-based data processing (post-Brexit considerations)

Key contract clauses:

  • Purpose limitation
  • Data retention periods
  • Security measures
  • Breach notification (within 72 hours)
  • Return/deletion of data upon contract termination

Cross-Border Data Transfers

UK to EU transfers:

  • UK adequacy decision covers most transfers
  • Monitor for any changes post-Brexit
  • Standard Contractual Clauses as backup

Transfers outside UK/EU:

  • Adequacy decisions (limited countries)
  • Standard Contractual Clauses
  • Binding Corporate Rules
  • Certification schemes

Breach Response Procedures

If health data is compromised:

Within 72 hours:

  • Notify ICO (or relevant EU authority)
  • Document the breach circumstances
  • Assess risk to employee rights

Without undue delay:

  • Notify affected employees if high risk
  • Provide clear information about the breach
  • Outline steps being taken to address it

Industry-Specific Considerations

Healthcare/Care Workers:

  • Enhanced screening justified
  • Professional body requirements
  • Occupational health referrals

Construction/Manufacturing:

  • Safety-critical role justifications
  • Regular re-screening requirements
  • Emergency medical information

Transport/Logistics:

  • DVLA medical standards
  • Regular fitness assessments
  • Drug and alcohol policies

Documentation Requirements

Maintain records of:

  • Legal basis for processing
  • Consent forms and dates
  • Data sharing agreements
  • Retention and deletion schedules
  • Employee training records
  • Data protection impact assessments
