In 2025, the convergence of AI and data privacy has become one of the most critical issues in UK marketing. With the Online Safety Act 2023 now in force (Phase 1 complete, Phase 2 under way) and the newly passed Data (Use and Access) Act 2025 (DUAA) amending the UK GDPR and Data Protection Act, brands must balance innovation with integrity.
For London-based businesses in particular, understanding how AI processes customer data is not only a compliance matter but also a brand-trust imperative.
At Glanz, we guide brands to adopt AI-driven marketing strategies responsibly, prioritising transparency, data ethics, and measurable growth.
The Growing Role of AI in Local Marketing
AI is revolutionising the way UK businesses reach and engage audiences. From automated ad targeting to predictive analytics, machine learning enables campaigns to be smarter, faster and more precise. Yet this advanced data use also amplifies privacy risks.
The Information Commissioner’s Office (ICO) emphasises that processing data with AI must meet the same principles of fairness, transparency, and accountability set out in UK GDPR.
In local marketing, especially for UK brands leveraging location-based data and personalisation, ensuring compliant data use is now a strategic necessity.

Understanding the Legal Landscape
UK regulation has moved rapidly:
- The Online Safety Act mandates that search services and platforms manage risks from illegal content and protect children from harmful material. Phase 2 (child-safety) took effect from 25 July 2025.
- The DUAA, passed 19 June 2025, amends key elements of UK GDPR and the Data Protection Act.
- The ICO’s AI and Data Protection guidance is being updated in light of growing generative AI use and profiling.
For brands using AI in marketing workflows this means:
- Documenting how AI models use personal data
- Ensuring consent and transparency when making automated decisions
- Assessing profiling risks, especially if location, biometric or behaviour data is involved
- Ensuring lawful bases of processing are clearly defined
Small and medium UK brands must view this regulatory complexity not as a barrier but as a chance to build trust. A privacy-first approach can become a differentiator.
