Businesses across the UK now have less than one month to prepare for significant new legal obligations relating to data protection complaints. Whether you buy a B2B data list, manage marketing outreach, or operate as a company data list provider, these changes affect you directly.
From 19 June 2026, organisations will be legally required to manage data protection complaints under the Data (Use and Access) Act 2025. The new requirements aim to strengthen accountability, improve transparency, and ensure businesses handle privacy concerns more effectively.
For organisations involved in marketing, customer communications, lead generation, data handling, or business intelligence, this change represents an important compliance milestone.
What Will Change on 19 June 2026?
Under the new legal framework, organisations must have a clear and accessible process in place for handling data protection complaints.
From 19 June 2026, businesses will be required to:
These new obligations apply to organisations handling personal data across a wide range of sectors, including marketing agencies, recruitment firms, SaaS providers, telemarketing businesses, public sector suppliers, and B2B data companies.
Why This Matters for UK B2B Marketing and Data Businesses
Data protection compliance is no longer simply a legal requirement — it has become a key factor in maintaining customer trust and protecting business reputation. This is especially true for organisations that purchase email marketing lists, manage prospect databases, or supply B2B marketing data to third parties.
Businesses that fail to handle complaints effectively may face:
A well-structured complaints process helps organisations demonstrate accountability while improving customer confidence in how personal data is managed. For businesses operating in data-driven industries, strong governance processes are increasingly essential.
Data Protection Complaints Are Not Just About Breaches
Many organisations assume data protection complaints only relate to serious data breaches. In reality, complaints often involve everyday operational issues such as:
Staff training will therefore play a critical role in helping employees recognise and appropriately escalate data protection concerns.
Businesses should ensure their teams understand what constitutes a data protection complaint and how these complaints should be managed internally.
Key Questions Businesses Should Ask
As the compliance deadline approaches, organisations should review whether their current complaints handling process meets the upcoming legal requirements.
Important questions include:
Is the complaints process clearly visible?
Customers and contacts should be able to easily identify how to raise a data protection concern without confusion.
Are data protection complaints separated from general complaints?
Many businesses currently combine privacy-related issues within broader customer service processes. The new framework may require clearer categorisation and documentation.
Can the business evidence compliance timelines?
Organisations should be able to demonstrate:
Accurate record-keeping will become increasingly important.
Do employees understand the process?
Staff should receive guidance on recognising data protection concerns and escalating them appropriately.
The ICO Is Encouraging Businesses to Prepare Now
Emily Keaney, Deputy Commissioner for Regulatory Policy at the Information Commissioner’s Office (ICO), recently confirmed that organisations still have time to prepare before the new requirements take effect.
The ICO has specifically acknowledged that smaller organisations may not yet have formal complaints processes in place. To support businesses, practical guidance and examples have already been published to help organisations understand what they must, should, and could do to comply.
This guidance is particularly valuable for SMEs that may not have dedicated compliance teams or extensive internal legal resources.
Why Compliance Matters in B2B Marketing and Data Services
For businesses involved in B2B marketing, lead generation, and business data services, compliance standards continue to evolve rapidly. If you need to buy a B2B data list, understand B2B marketing list pricing, compare B2B prospect database pricing, or are looking to request a quote for business data, choosing a supplier with a documented compliance framework is no longer optional — it is essential. At AD Marketing, compliance remains central to our approach. As an independent company data list provider with over 30 years of UK market experience, we supply telephone-verified, GDPR and PECR compliant B2B data with full Article 14 documentation included with every order.

Taking proactive action now can help reduce compliance risks and improve organisational readiness ahead of the deadline.
Final Thoughts
The introduction of the Data (Use and Access) Act 2025 marks another important development in the UK’s evolving data protection landscape.
Businesses that implement clear, accessible, and accountable complaint handling processes before 19 June 2026 will be better prepared to meet their legal obligations while strengthening trust with customers and business contacts.
For organisations that purchase email marketing lists or rely on a B2B prospect database to drive new business, effective compliance is not simply about avoiding risk — it is about building credibility, transparency, and long-term business confidence.
