Data privacy has always been a critical issue for businesses handling personal information. But in 2025, it’s more important than ever to understand how UK laws have developed and what’s on the horizon.
From the introduction of the General Data Protection Regulation (GDPR) in 2018 to ongoing updates to the Privacy and Electronic Communications Regulations (PECR), the rules continue to evolve to keep pace with technology and changing consumer expectations.
A quick history of UK data privacy laws
While the UK had data protection rules before GDPR, it was the EU-wide regulation that marked the biggest change in how organisations collect, process, and store personal data. GDPR was adopted into UK law via the Data Protection Act 2018, and after Brexit, the UK retained its own version, often referred to as “UK GDPR”.
PECR regulations, on the other hand, have been around since 2003. They focus on privacy in electronic communications, covering marketing emails, cookies, and other online tracking technologies. Unlike GDPR, which is broad in scope, PECR targets the way businesses communicate with customers digitally.
Key changes in recent years
Since 2018, GDPR compliance in the UK has remained a central focus for regulators, but there have been several important updates:
- Increased enforcement: The Information Commissioner’s Office (ICO) has stepped up fines for breaches, with penalties in the millions for serious violations.
- Evolving guidance: New recommendations clarify how to handle data in emerging areas like AI, automated decision-making, and profiling.
- Alignment with technology trends: Changes to consent rules and transparency requirements have been influenced by developments in online advertising and tracking.
For PECR regulations, recent years have seen greater emphasis on cookie consent, particularly following high-profile enforcement actions against non-compliant websites.
What’s new for 2025
While the core principles of GDPR and PECR remain, 2025 brings some noteworthy developments:
- Stricter rules on AI data processing: The UK is introducing clearer guidelines on using personal data for AI training and decision-making.
- Updated cookie consent requirements: Businesses must ensure consent mechanisms are explicit, accessible, and easy to withdraw.
- Stronger protections for children’s data: Building on the Age Appropriate Design Code, there is an increased focus on safeguarding under-18s online.
These updates aim to strike a balance between innovation and privacy, ensuring that businesses can use data responsibly while protecting individual rights.
The overlap between GDPR and PECR
While they’re separate regulations, GDPR compliance in the UK and PECR regulations often work together. For example:
- If you send marketing emails, PECR governs the method of communication (e.g., opt-in requirements), while GDPR governs how you store and process the personal data involved.
- Both require transparency: you must tell people what you’re doing with their data, why, and how they can object or opt out.
Ignoring one can undermine compliance with the other, so businesses must take a holistic approach to privacy.
Steps for businesses to stay compliant in 2025
- Review your data mapping: Know exactly what personal data you collect, where it’s stored, and who has access to it.
- Update privacy notices: Reflect any changes in law or business practice in your public-facing policies.
- Audit your marketing practices: Ensure email, SMS, and digital campaigns meet both PECR regulations and GDPR requirements.
- Train your staff: Everyone handling personal data should understand the basics of compliance.
- Monitor legal updates: Privacy law is a moving target, so staying informed is key.
Why compliance is worth the effort
Beyond avoiding fines, GDPR compliance in the UK and adherence to PECR regulations help build trust with customers. In an age where consumers are increasingly concerned about how their data is used, demonstrating that you take privacy seriously can be a competitive advantage.
It’s also worth noting that non-compliance can harm your marketing performance: for example, poorly obtained consent can lead to higher spam complaints, lower engagement, and reputational damage.
Take regulation seriously
In 2025, UK data privacy laws are continuing to adapt to new technology and shifting public expectations. For businesses, this means staying vigilant, understanding the nuances of both GDPR compliance in the UK and PECR regulations, and embedding privacy best practices into every part of your operations.
By doing so, you not only reduce legal risk but also strengthen relationships with the people whose data you hold, turning compliance from a box-ticking exercise into a key part of your brand’s reputation.
