Web accessibility: what businesses need to know in 2026
What web accessibility means, why the legal and commercial stakes rose sharply in 2025, and what an accessible website actually requires.
Web accessibility means building a website so that people with disabilities can use it: navigable by keyboard, readable by screen readers, with sufficient colour contrast, proper text alternatives for images, and content that does not rely on sight or hearing alone. It is measured against the WCAG standard. In 2026 it is both a legal requirement for a growing number of businesses and a commercial issue that quietly affects every site, because roughly one in six people has a disability.
For years accessibility was treated as optional, a nice-to-have that agencies mentioned and clients skipped. That has changed. The legal landscape tightened significantly in 2025, and the commercial case was always stronger than most businesses realised. Here is what you actually need to know.
What accessibility actually means
Accessibility is not one feature. It is a set of practices that make a site usable by people with visual, motor, auditory, and cognitive disabilities. In practice that includes: everything operable by keyboard alone, not just a mouse; images with meaningful text alternatives so screen readers can describe them; colour contrast high enough to read with low vision; text that resizes without breaking; forms that announce their labels and errors; video with captions; and content that does not depend on colour alone to convey meaning. The standard these are measured against is WCAG, the Web Content Accessibility Guidelines, usually at level AA.
Why the stakes rose in 2025
The reason accessibility moved up the agenda is that the law changed. The European Accessibility Act came into effect in 2025, extending accessibility requirements to many private-sector businesses that sell products and services to consumers in the EU, including e-commerce, banking, and digital services. Alongside long-standing obligations in other jurisdictions, this means a large number of businesses that previously treated accessibility as optional now have a legal reason to take it seriously. The specifics vary by country, business size, and sector, so confirm your own obligations with a professional. But the direction is clear: the exemptions are shrinking.
Who has to comply
This is the part to check carefully rather than assume. Broadly, larger businesses selling to consumers, particularly in e-commerce, finance, transport, and digital services, are most likely to fall under the new requirements, with some exemptions for the smallest businesses. Public sector bodies have had obligations for longer. If you sell to consumers in the EU or run a site in a regulated sector, assume it applies and verify. If you are a tiny local business, you may be exempt from the letter of the law while still losing customers to an inaccessible site.
The commercial case beyond compliance
Even where the law does not compel you, the numbers do. Roughly one in six people lives with a disability. An inaccessible site turns those visitors away silently, the same way a step turns away a wheelchair user before they reach the door. Accessible sites also tend to be better sites for everyone: clearer structure, better contrast, faster keyboard navigation, and cleaner semantic markup that also helps SEO. Accessibility and quality pull in the same direction more often than not.
What an accessible site actually requires
- Semantic HTML, so the structure is meaningful to assistive technology, not just visually
- Full keyboard operability, with a visible focus indicator
- Text alternatives for all meaningful images
- Colour contrast that meets WCAG AA
- Labelled, error-announcing forms
- Captions for video and transcripts for audio
- No information conveyed by colour alone
- Text that reflows and resizes without breaking the layout
None of this is exotic. It is mostly a matter of building correctly from the start, which is far cheaper than retrofitting accessibility onto a site that ignored it.
Common failures
The usual offenders: images with no alt text, forms you cannot complete with a keyboard, pale grey text nobody with less than perfect vision can read, buttons that are actually unlabelled icons, pop-ups that trap keyboard focus, and video with no captions. Automated checkers catch some of this, but real accessibility needs a human to test with a keyboard and a screen reader, because a site can pass an automated scan and still be unusable.
What to do about yours
Start by finding out where you stand. Run an automated audit for the obvious issues, then have someone test the key journeys with a keyboard and a screen reader. Fix the serious barriers first, the ones that make the site impossible rather than merely awkward. If you are building or rebuilding, make accessibility a requirement from the brief rather than a final polish, because building it in is cheap and bolting it on is not. And if your business plausibly falls under the new legal requirements, treat it as the compliance issue it now is, not the optional extra it used to be.
