The 4 principles of digital accessibility

Since 28 June 2025, the European Accessibility Act (EAA) requires webshops, apps, banks and streaming services across the EU to comply with WCAG 2.1 level AA. The European Commission uses WCAG 2.2 AA as its reference standard. Every feature is tested against these fundamental pillars.

Perceivable

Information and UI components must be perceivable to all users, regardless of their sensory abilities.

Operable

Interface components and navigation must be operable through a range of input methods.

Understandable

Information and UI operation must be understandable to users with different abilities.

Robust

Content must be robust enough to be interpreted reliably by a wide variety of user agents and assistive technologies.

Accessible apps for every sector

In the Netherlands, at least 1 in 8 people aged over 12 has a moderate to severe impairment in sight, hearing or mobility (CBS). Within the EU, 17% fewer people with a disability use the internet compared with people without one (Surfshark/Eurostat). Accessibility is not a luxury but a legal and social necessity.

Government & public services

Legally mandated accessibility for government services. Full WCAG 2.1 AA compliance with a focus on universal access.

DigiD integration Form accessibility Multi-language support Emergency alerts

Healthcare & wellbeing
