The New Accessibility Strengthening Act and What It Means for Your Website

A Brief Summary of the Web Content Accessibility Guidelines

The Web Content Accessibility Guidelines (WCAG) define the four principles of accessibility, summarised under the acronym POUR:

Perceivable

One of the most important points defined by the WCAG is that all content on websites, mobile applications and software interfaces must be accessible to all the senses – not just visually.

To achieve this goal, you should provide text alternatives for images, videos and audio files. Sufficient contrast between text and background is also crucial for optimal perceptibility. It must also be possible to enlarge content without losing information or functions.

Operable

To ensure that all users can use the website without barriers, it should be fully keyboard accessible. The user guidance must be clearly structured so that the focus is visible at all times. In addition, the placement of flashing or flickering elements should be avoided in order to prevent health impairments such as seizures or nausea. Navigation should be consistent and predictable so that users can find their way around at all times.

Understandable

Your website should be designed according to this principle not only technically, but also in terms of content. Texts and functions must therefore be understandable and predictable. Simple language should be used and clear instructions given. Errors – for example in forms – should be clearly labelled and easy to correct.

Robust

In functional terms, the Web Content Accessibility Guidelines (WCAG) also require content to be compatible with current and future technologies. This includes correct HTML and CSS as well as semantically clean labelling. Assistive technologies must also be able to interpret the content reliably.

According to the Web Content Accessibility Guidelines, the degree of accessibility of your website can be categorised into different compliance levels: Level A fulfils the minimum requirements according to these, AA corresponds to the recommended standard and is often mandatory by law and AAA is defined as the highest level, which is usually fulfilled voluntarily – until now!

This Is What the New Accessibility Strengthening Act Says

Starting in summer 2025—specifically on June 28—the Accessibility Strengthening Act (BFSG) will come into effect. It serves to implement EU Directive 2019/882 of the European Parliament and Council dated April 17, 2019.

The aim of the BFSG is to create a unified legal framework for accessible products and services within the EU internal market. The legal basis includes not only EU Directive 2019/882 and the BFSG as a federal law but also the corresponding Accessibility Strengthening Act Regulation (BFSGV). This framework is complemented by existing regulations such as the Equal Opportunities for Persons with Disabilities Act (BGG), the General Equal Treatment Act (AGG), and the Telecommunications Act (TKG).

Who Is Affected by the Requirements of the Accessibility Strengthening Act

The legislation clearly defines who must implement the requirements of the BFSG by the end of June 2025: Primarily, it applies to private companies that offer certain digital services, such as e-commerce, e-books, online banking, and passenger transport.

Online shops and websites with sales functions, as well as mobile apps, software, and hardware with digital interfaces, are also required to comply with the BFSG regulations.

BFSG – These Are the Legal and Technical Requirements

From a technical perspective, the requirements of the international standard for accessible web content must be implemented—in line with the classification of the Web Content Accessibility Guidelines (WCAG), this corresponds to conformance level AA.

We’ve summarised these requirements for you here:

• Text alternatives
  • All non-text content (images, icons, CAPTCHA) must have text alternatives (alt texts)
• Audiovisual content
  • Videos must have subtitles (1.2.4).
  • Audio description or full text alternatives for videos must be provided (1.2.5).
• Layout & design
  • The text must have a contrast of at least 4.5:1 to the background (1.4.3)
  • Text sizes must be scalable up to 200% without loss of function (1.4.4)
  • The contrast of UI components and graphic texts must be at least 3:1 (1.4.11).
  • Likewise, content must not be displayed exclusively in different colours (1.4.1)
  • Content must also not be triggered by movement, i.e. tilting or shaking (2.5.4)
• Keyboard operability
  • All functions must be operable by keyboard (2.1.1) and users must not be irritated by keyboard traps (2.1.2)
• Time restrictions
  • Time limits must be customisable or can be switched off (2.2.1)
• Readability
  • The programming language of the document must be declared (3.1.1)
  • Language changes must also be labelled in the text (3.1.2)
• Navigation
  • Visible keyboard focus for interactive elements (2.4.7)
  • Consistent navigation across all pages (2.4.5)
  • Provide jump links/skip links (2.4.1)
  • Meaningful page titles (2.4.2)
  • Descriptive link texts (e.g. no “click here”) (2.4.4)
• Predictable behaviour
  • All components must behave predictably and consistently (3.2.3)
• Support in the event of errors
  • Form errors must be described and explained (3.3.1) and suggestions for correcting errors must be offered. It must also be possible to provide labelling and instructions for input errors (3.3.2)
• Compatibility with technologies
  • All content should be usable with screen readers and other assistance systems (4.1.2).
  • Clean, valid HTML code should be implemented (4.1.1)

The legal and regulatory basis for this is not only the German Accessibility Improvement Act (BFSG), but also the German Product Safety Act (ProdSG) for accessible end devices and the European standard DIN EN 301 549 on digital accessibility. There are also documentation obligations, such as the declaration of accessibility and a feedback function.
