Briefing note – The Data (Use and Access) Act 2025: what has changed and what should your business do?


Prepared following our Lunch & Learn session, 16 September 2026 by Rhian Burke and Jo Brianti.

The Data (Use and Access) Act 2025 (DUA Act) received Royal Assent on 19 June 2025. It does not replace UK GDPR, the Data Protection Act 2018 or PECR; instead, it makes targeted changes to the existing framework.

For most businesses, this is evolution rather than revolution. The key question is not whether you need to rebuild your data protection framework, but which changes affect what you already do.

TL;DR

What has changed?

Automated decision-making

Subject access requests

Data protection complaints

Cookies and similar technologies

PECR enforcement

International transfers

Other changes worth knowing about

Recognised Legitimate Interests

Re-use of data and scientific research

Children’s online services

Charity soft opt-in

The common thread – know your data

Almost every change discussed during the webinar comes back to the same starting point.  Before you can determine whether a change affects your business, you need to understand:

what personal data you use, why you use it, which systems hold it, who it is shared with, whether it leaves the UK and whether activities such as profiling, automated decision-making or online tracking are taking place.

A useful RoPA or data map brings that information together.

Its value goes beyond demonstrating compliance. If a SAR arrives, there is a data incident, a customer asks detailed due-diligence questions or the business wants to introduce a new AI tool, you already have somewhere to start rather than trying to reconstruct the picture from systems, spreadsheets, inboxes and people’s knowledge.

3 things to take-away

Know your data. It makes everything else easier.
