Post-Brexit GDPR Compliance Made Simple with Automation

The Post-Brexit Data Landscape

When Brexit happened, UK businesses gained their own data protection regime—the UK GDPR—which sits alongside the existing GDPR for dealings with the EU. For tech SMEs, this creates a compliance landscape that's more complex than before, but not as complicated as it might seem.

The good news? Most of the practical requirements haven't changed dramatically. The even better news? Automation can handle much of the compliance burden that used to require manual processes or expensive consultants.

What Actually Changed

The Basics Remain the Same

For most business purposes, UK GDPR mirrors EU GDPR closely:

• Same fundamental principles
• Same individual rights
• Same security expectations
• Same breach notification requirements

Your existing GDPR compliance work isn't wasted—it's the foundation.

What's Different

The key changes affect:

International Data Transfers:

• UK no longer automatically part of EU data space
• Transfers between UK and EU require legal basis
• Transfers to other countries follow UK adequacy decisions (which differ from EU decisions in some cases)

Regulatory Authority:

• ICO is sole regulator for UK GDPR
• EU supervisory authorities for EU-resident data subjects
• Potential for dual reporting in some scenarios

Domestic Variations:

• UK-specific exemptions being developed
• Some divergence in enforcement interpretation
• Data Use and Access Act 2025 changes coming into effect

Why SMEs Struggle with Dual Compliance

No Dedicated Compliance Team

Unlike larger organisations, tech SMEs typically don't have:

• A Data Protection Officer (even when technically required)
• Legal counsel on retainer
• Compliance specialists
• Dedicated training programmes

Compliance becomes everyone's responsibility, which often means it's no one's priority.

Complex Customer Geography

A 20-person tech SME might serve:

• UK customers (UK GDPR applies)
• EU customers (EU GDPR applies)
• US customers (potentially CCPA and others)
• Various international clients

Each geography brings different requirements and the lines blur constantly.

Evolving Requirements

Both UK and EU data protection regimes continue to evolve:

• New regulatory guidance
• Court decisions clarifying interpretation
• Legislative amendments
• Enforcement trends shifting

Keeping up is a continuous task, not a one-time project.

Automating Your Way to Compliance

Consent Management

The most automatable aspect of data protection is consent:

What to Automate:

• Cookie consent collection and recording
• Marketing preference management
• Third-party data sharing consent
• Consent withdrawal processing

How:

• Consent management platforms (OneTrust, Cookiebot, Termly)
• Integrated preference centres in marketing tools
• Automated consent logs in CRM systems
• API-driven consent checking before communications

Benefit: You'll always know what consent you have, when you got it, and can prove it if asked.

Data Subject Requests

Under both UK and EU GDPR, individuals have rights to access, correct, delete, and port their data. These requests can be time-consuming to process manually.

What to Automate:

• Request intake through web forms
• Identity verification workflows
• Data location and extraction
• Response generation and delivery
• Audit trail documentation

How:

• Dedicated DSR platforms (DataGrail, OneTrust, TrustArc)
• Custom workflows in tools like Airtable or Notion
• Integration with data warehouses for automated extraction
• Template libraries for standard responses

Benefit: Meet the one-month response deadline consistently without manual scrambling.

Data Mapping and Inventory

Knowing what data you hold, where it lives, and how it flows is fundamental to compliance—but it's often the most neglected area.

What to Automate:

• Discovery of data across systems
• Classification of personal data types
• Data flow documentation
• Retention schedule tracking

How:

• Data discovery tools (BigID, Varonis)
• Integration platforms that track data flows (Workato, Tray.io)
• Regular automated audits
• Centralised data catalogues

Benefit: When auditors or regulators ask what data you hold on someone, you can actually answer.

Breach Detection and Response

Both regimes require breach notification within 72 hours in many cases. That's not much time for detection, assessment, and reporting.

What to Automate:

• Security monitoring and anomaly detection
• Automated incident logging
• Severity assessment workflows
• Notification triggers and templates
• Communication with affected parties

How:

• Security monitoring tools with alerting
• Incident response playbooks in IT service management tools
• Pre-approved notification templates
• Automated regulator notification preparation

Benefit: When something goes wrong, you respond systematically rather than panicking.

Practical Implementation Approach

Phase 1: Get the Basics in Order

Week 1-2:

• Implement cookie consent (if not already done)
• Create data subject request intake form
• Document your main data processing activities
• Review and update privacy notice

Tools: Cookiebot or similar (£10-50/month), web form builder, simple spreadsheet for processing records

Phase 2: Automate Core Processes

Week 3-6:

• Set up DSR workflow automation
• Integrate consent tracking with marketing tools
• Implement basic security monitoring
• Create breach response playbook

Tools: Workflow automation (Zapier, Make.com), security tool with alerting, documented procedures

Phase 3: Build Continuous Compliance

Month 2-3:

• Expand data mapping to cover more systems
• Implement retention automation
• Set up compliance dashboards
• Create regular review cadence

Tools: More sophisticated data mapping if needed, dashboard tools, calendar reminders for reviews

International Transfer Mechanisms

For tech SMEs moving data internationally, here's the practical approach:

UK-EU Transfers

Currently straightforward due to adequacy decisions:

• UK to EU: EU adequacy decision for UK in place
• EU to UK: UK adequacy decision for EU in place

Action Required: Minimal, but document your reliance on adequacy decisions.

Transfers to Other Countries

Where no adequacy decision exists (e.g., US for general purposes):

Options:

1. Standard Contractual Clauses (SCCs) - Template contracts approved by regulators
2. Binding Corporate Rules - For internal group transfers
3. Explicit consent - For specific, occasional transfers
4. Contractual necessity - If transfer is essential to deliver services

Practical Advice: Most SMEs use SCCs with US vendors. Many major platforms (AWS, Microsoft, Google) have these built into their terms.

Common Mistakes to Avoid

Over-Complicating Things

Some businesses freeze because compliance seems overwhelming:

• Perfect is the enemy of good
• Basic compliance now beats perfect compliance never
• Document what you're doing and why

Under-Investing in Basics

Others assume compliance is someone else's problem:

• Every business processing personal data has obligations
• Size doesn't exempt you from requirements
• Breaches don't care about your resource constraints

Treating Compliance as One-Time

GDPR compliance isn't a project with an end date:

• Regulations evolve
• Business processes change
• New data types emerge
• Review regularly

The Bottom Line

Post-Brexit data protection compliance is manageable for tech SMEs. The requirements aren't radically different from what came before, and automation makes ongoing compliance far more achievable than manual processes ever did.

Start with the basics, automate what you can, and build compliance into your regular operations rather than treating it as a separate burden.
