What the WebAIM Million 2025 Report Tells Us About Website Accessibility

The WebAIM Million 2025 Report is one of the most thorough reports on the accessibility of websites across the internet. Each year, it analyses the homepages of the top 1 million websites to assess how well they meet the Web Content Accessibility Guidelines (WCAG). The 2025 edition is now live and the results are once again sobering.

While this report doesn’t focus solely on the public sector, the findings highlight a widespread failure to meet even the basic accessibility standards. For senior leaders in public bodies and managers of private sector businesses alike, the message is the same. Accessibility is still being overlooked across the board.

Key Findings from the WebAIM Million 2025 Report

Across the top 1 million homepages tested, WebAIM found:

  • 94.8% had at least one WCAG 2 failure
  • The average page had 51 errors
  • 79.1% of pages included low contrast text
  • 55.5% of images lacked meaningful alt text
  • Over one-third had empty links or buttons

These aren’t edge cases. These are widespread, recurring accessibility problems found on some of the world’s most visited websites.

Why Website Accessibility Matters for Public and Private Sectors

The WebAIM Million doesn’t distinguish between sectors, but in the UK, public sector organisations are legally required to meet WCAG 2.1 AA standards (and now 2.2). For these organisations, the stakes are clear, legal compliance, inclusive service delivery and public trust.

But for private businesses, the pressure is increasing too. As accessibility becomes more visible and user expectations rise, businesses that ignore it risk excluding users, damaging brand perception and falling behind competitors that take it seriously. Whatever the audience, from residents and patients to tenants and customers, inaccessible websites fail to meet the needs of everyone.

Our Take: Accessibility Is Still an Afterthought, Until It’s Not

In our experience, accessibility tends to be considered too late in the process. It’s seen as an extra, not a foundation. That mindset creates risk and adds cost later down the line. Many of the issues raised in the WebAIM Million 2025 Report, such as low contrast, missing alt text and poor link structures, are straightforward to avoid when accessibility is part of the brief from day one.

We’ve seen first-hand how accessibility can be delivered without compromise. When we worked with NHS East London Foundation Trust on their QI microsite, accessibility wasn’t just a tick-box, it was a requirement. The result is a site that’s clear, navigable and compliant, without sacrificing design or usability.

Website Accessibility for Public and Private Sector Teams

If you’re commissioning a new website or updating your current one, the WebAIM Million should be a wake-up call. It shows just how far off the mark most websites are and gives you a benchmark to aim higher.

For public sector organisations, accessibility is not optional. WCAG compliance is a regulatory requirement and digital inclusion is part of your public duty.

For private sector teams, it’s an opportunity to lead. Accessible websites work better for everyone. They’re more usable, more inclusive and often perform better across SEO and mobile too.
