Data Privacy in 2025: Why Choosing a Trusted Supplier Still Matters

Data privacy is a top priority in 2025 for any business using marketing data. With rising GDPR enforcement and ongoing fallout from scandals like Cambridge Analytica, the risks of using poorly sourced or non-compliant data remain high. This is especially true for suppliers in the construction and fenestration sectors who rely on accurate B2B data to reach installers, builders, and trade professionals.

Data misuse: Still damaging in 2025

In late 2024, Meta paid over A$50 million in damages in Australia linked to Facebook data misuse. In 2025, US courts will continue to review investor lawsuits related to the scandal. The message is clear: poorly sourced or outdated data creates a serious risk. For construction suppliers and trade professionals using B2B data, this matters more than ever.

What does it mean for fenestration and construction marketing

If you rely on data to target builders, installers, or specifiers, non-compliant data could expose you to:

• ICO investigations
• Email delivery issues or blocked campaigns
• Customer complaints or opt-out disputes
• Loss of brand trust and reputational damage

How Insight Data helps protect your business

Insight Data provides fully compliant B2B marketing data tailored for the construction, glazing and fenestration industries. Our approach includes:

• Verified data collection – All records are gathered in-house with lawful, consent-based methods
• Real-time updating – Data is refreshed continually, not just quarterly or annually
• Transparent privacy policies – Written in plain English with full disclosure on usage
• Suppression screening – All contacts are checked against TPS, CTPS, and relevant opt-outs
• UK GDPR compliance – We operate under the strictest interpretation of UK and EU data law

What to ask your data supplier in 2025

Before buying any marketing list, ask:

• When was the data collected and last verified?
• What consent was given by the data subject?
• Has the data been screened against TPS/CTPS?
• Does the supplier have a record of complaints?
• What lawful basis is being used for processing?
• Is the privacy notice clear and accessible?

If your supplier avoids these questions or offers vague answers, you’re taking a risk that could cost you financially and reputationally.

Regulatory trends and legal risks in 2025

Key developments this year include:

• Increased scrutiny of “dark pattern” consent pop-ups
• Rising class actions and investor lawsuits linked to misuse
• More publishers and advertisers are introducing pay-or-consent data models

These trends show that data compliance isn’t just about legality—it’s now core to trust, reputation, and commercial viability.
