UK Data Law Changed in June. Here's What Your Business Needs to Do Now.

Published on July 13, 2026 by MARS

The Short Answer

  • UK data law changed on 19 June 2026 under the Data (Use and Access) Act 2025
  • Every business with a website now needs updated compliance documents
  • There are no exemptions, regardless of size
  • A mandatory complaints procedure is already a legal requirement
  • Maximum fines for marketing breaches increased from £500,000 to £17.5 million
  • MARS offers a fixed-fee compliance update at £450, delivered within five working days

Most businesses missed it. On 19 June 2026, new legal requirements came into force under the Data (Use and Access) Act 2025, and most business owners have no idea it happened. That's not a criticism. It's a busy law with a quiet rollout. But the consequences of doing nothing are real, and worth understanding.

What Actually Changed


The Data (Use and Access) Act 2025 is the most significant update to UK data protection law since GDPR came in eight years ago. It doesn't replace UK GDPR. It amends it, in ways that directly affect how businesses handle personal data.

1. You now need a formal complaints process

From 19 June 2026, every organisation that processes personal data is legally required to have a data protection complaints procedure in place. There is no exemption, regardless of size. That means a written policy, a way for people to submit complaints, and a 30-day acknowledgement requirement. If you don't have this, you're already out of compliance.

2. Your privacy policy is probably out of date

Privacy notices need to be updated to reflect the new complaints right. If your policy was written before this year and hasn't been reviewed, it almost certainly doesn't include what it now needs to.

3. Marketing fines just got much larger

The maximum fine for breaches of PECR, the regulation that covers email marketing and cookies, has increased from £500,000 to £17.5 million. If you send marketing emails or use cookies on your website, this is the environment you're now operating in.

What You Need to Have in Place


At a minimum, UK businesses now need:

  • An updated website privacy policy reflecting the DUAA changes
  • A data protection complaints policy
  • A complaints acknowledgement process with a 30-day response requirement
  • A subject access request procedure updated for the new rules
  • A marketing compliance review if you send emails or run ads

Most businesses already have some version of these documents. The issue is that existing documents were written under the old rules and haven't been updated.

How I Can Help


I offer a fixed-fee DUAA Compliance Update at £450.

The service covers a full review of your existing privacy policy and compliance documents, updates based on solicitor-drafted DUAA templates, a ready-to-publish privacy policy tailored to your business, a data protection complaints policy and acknowledgement template, and a plain-English summary of what changed and why. Everything delivered within five working days.

These documents are based on professionally drafted legal templates. I'm not a solicitor and this isn't legal advice. For the vast majority of businesses, this service covers exactly what you need. If your situation is more complex, I'll tell you upfront.

Frequently Asked Questions


Does this apply to me if I'm a sole trader?

Yes. The legal requirement applies to every organisation that processes personal data, including sole traders and partnerships. If you have a contact form, a mailing list, or a booking system on your website, this applies to you.

I already have a privacy policy. Do I still need to update it?

Almost certainly yes. Privacy policies written before 2026 won't include the new complaints right or reflect the updated legal position under the DUAA. The question isn't whether you have a policy, it's whether it reflects current law.

What if I already have GDPR documents in place?

Having documents in place is a good start. The issue is that documents written under the old rules don't reflect what the law now requires. An update is faster and cheaper than starting from scratch, which is exactly what this service covers.

Is this legal advice?

No. MARS is a digital marketing consultancy, not a law firm. The documents I provide are based on solicitor-drafted templates and reflect current UK data protection law. If your business has complex data processing needs, I'll tell you and point you toward the right specialist.


The deadline has passed. The longer this sits, the longer your business is operating without the documentation the law now requires. If you'd like to get this sorted, visit the link below and I'll come back to you within one working day.
