On 12 September 2025, the EU Data Act will officially come into force, marking one of the most significant regulatory shifts in the European data economy to date.
With its focus on fairness, transparency and access, the regulation aims to democratize data generated by connected devices, while ensuring that consumers, businesses and public institutions can benefit from a more open and competitive digital environment.
But what does this mean in practical terms?
Key Rulings of the EU Data Act
1. Access to Connected Device Data: The Data Act gives users the right to access data produced by their own devices; everything from smart thermostats to industrial machines. This is a major change from the current landscape, where manufacturers typically control that data. Now, individuals and companies can decide to share this information with third parties, potentially unlocking value through better services, maintenance or insights.
2. Easier Switching Between Cloud Services: The regulation introduces obligations for data processing services to enable smooth switching between providers. By reducing vendor lock-in, it empowers businesses to shop around for the best services without being stuck in restrictive contracts. This is expected to increase competition and innovation in the cloud services market.
3. Public Sector Access in Emergencies: In exceptional situations; such as pandemics or natural disasters; public sector bodies will be allowed to access relevant private sector data. This access is tightly regulated but aims to help governments respond more effectively to crises by relying on real-time, high-quality data.
4. Safeguards for SMEs and Cross-Border Transfers: The Act protects small and medium-sized enterprises from unfair contract terms and limits the forced transfer of non-personal EU data to jurisdictions with weaker protections. This promotes a more secure and balanced digital playing field within Europe and abroad.
Business and Consumer Impact
For businesses, the Act requires rethinking data strategies, especially for those dealing in connected products or cloud services. Compliance will involve new technical and contractual standards to meet transparency and portability requirements.
For consumers, the Act promises greater control and new opportunities. Whether it’s choosing how data from your smart home is used, or switching between service providers with ease, the regulation hands more power back to the user.
Closing Thoughts
The EU Data Act is more than just another regulation; it’s a fundamental change in how data is shared, accessed and protected across Europe. By encouraging openness and trust, it sets the stage for a more competitive, secure and innovation-driven data economy.
At Dark Light, we welcome this regulation as an important step forward. It encourages companies not only to become compliant, but also to think more strategically about how accessible, usable and valuable their data truly is.
