Web Accessibility Compliance: What Cardiff Businesses Need to Know in 2025

Most Cardiff business owners don't think about web accessibility until something goes wrong. A complaint. A social media callout. Or, in worst-case scenarios, a legal claim.

That's the wrong way to approach it. Web accessibility isn't just a technical checkbox — it's a legal obligation, a commercial opportunity, and frankly, good business practice. Done properly, an accessible website reaches more customers, ranks better on Google, and reduces the risk of reputational and legal damage.

This guide covers everything Cardiff businesses need to know: what WCAG is, what the law actually says, the most common failures we see on Welsh business websites, and how to start testing and fixing them today.

What Is WCAG and Why Does It Matter?

WCAG stands for the Web Content Accessibility Guidelines, published by the World Wide Web Consortium (W3C). These guidelines establish how digital content should be designed and coded so that people with disabilities — visual, auditory, motor, cognitive — can use it effectively.

The guidelines are organised into four principles, often summarised as POUR:

• Perceivable — information and UI components must be presentable in ways users can perceive (e.g. alt text for images, captions for video)
• Operable — interface and navigation must be operable (e.g. keyboard navigable, no seizure-triggering content)
• Understandable — information and operation must be understandable (e.g. clear language, predictable navigation)
• Robust — content must be robust enough to be interpreted by assistive technologies

WCAG has three levels: A (minimum), AA (standard), and AAA (enhanced). Most legal frameworks, including the UK's, reference WCAG 2.1 AA as the expected standard.

The Legal Obligation: What UK Law Actually Requires

Here's where many Cardiff businesses get caught out. There's a widespread assumption that accessibility law only applies to large corporations or public sector organisations. That's not entirely accurate.

The Equality Act 2010

The Equality Act 2010 is the primary piece of UK legislation relevant to web accessibility. Under the Act, businesses providing services to the public have a legal duty to make reasonable adjustments for disabled people. This includes digital services — your website.

The Act doesn't explicitly name WCAG, but case law and guidance from the Equality and Human Rights Commission (EHRC) makes it clear that failing to provide an accessible website could constitute indirect disability discrimination if it puts disabled users at a substantial disadvantage.

A reasonable adjustment, in digital terms, means ensuring your website can be used by someone who:

• Is blind and uses a screen reader
• Has low vision and needs to zoom to 200% without content breaking
• Has limited motor control and navigates by keyboard only
• Has cognitive difficulties and needs clear, simple language

If your Cardiff business serves the public — and most do — you have a legal obligation to consider these users.

Public Sector Bodies (Accessibility Regulations) 2018

If your organisation has any public-sector element — local authority partnerships, government contracts, publicly funded services — you're likely subject to the Public Sector Bodies (Accessibility) Regulations 2018, which explicitly require WCAG 2.1 AA compliance and mandate an accessibility statement on your website.

What's the Risk?

The EHRC has powers to investigate and enforce. Individual users can also bring county court claims under the Equality Act. While we haven't yet seen the wave of litigation that hit the US market under ADA, the trend is moving in that direction. For Cardiff businesses serving diverse communities, getting ahead of this is smart risk management.

The Commercial Case for Accessibility

Beyond legal compliance, there's a straightforward commercial argument for accessible website Cardiff design.

Market size: According to scope, around 14.6 million people in the UK have a disability. That's a significant slice of potential customers who may be using assistive technology to browse your site. If your website excludes them, you're losing business.

SEO uplift: Many WCAG requirements align closely with Google's technical SEO best practices. Alt text helps screen readers and Google's image indexing. Proper heading structure aids navigation and signals content hierarchy to search crawlers. Fast, clean, semantic HTML is better for everyone — including the algorithms that determine where you rank.

Better UX for everyone: Accessible design principles — clear contrast, logical structure, predictable navigation — improve the experience for all users, not just those with disabilities. An accessible website is typically a better website.

Brand reputation: In 2025, how you treat disabled users says something about your business values. Cardiff has a diverse, community-minded business culture. Accessibility is part of being a responsible local operator.

The Most Common Web Accessibility Failures We See

When we audit Cardiff business websites, the same issues come up repeatedly.

1. Images Without Alt Text

Alt text describes images for screen reader users and for Google. A product photo with no alt text is invisible to someone using a screen reader and sends an unhelpful signal to search engines. Fix: every meaningful image needs descriptive alt text; decorative images should have empty alt attributes (alt="").

2. Poor Colour Contrast

Text that doesn't have sufficient contrast against its background fails WCAG 1.4.3 (Contrast — Minimum). This affects people with low vision or colour blindness, but also anyone reading on a bright screen outdoors. WCAG AA requires a contrast ratio of at least 4.5:1 for normal text.

3. No Keyboard Navigation

Can you navigate your entire website — fill in forms, activate buttons, open menus — using only the Tab and Enter keys? Many Cardiff business sites can't. Users who rely on keyboards (including many motor-impaired users) hit dead ends at dropdowns, modals, and custom components.

4. Missing Form Labels

Form fields without properly associated labels are useless for screen reader users, who need to know what each field is for. Using placeholder text as a substitute doesn't work — it disappears when typing begins and often lacks adequate contrast.

5. Videos Without Captions

If you have video content on your website — a showreel, explainer video, testimonials — it needs captions for deaf and hard-of-hearing users. Auto-generated captions from YouTube are better than nothing but often inaccurate. Proper closed captions should be accurate and synchronised.

6. Inaccessible PDFs

Many Cardiff businesses publish PDFs — menus, brochures, price lists, terms and conditions — without considering whether they're accessible. Scanned PDFs are essentially images and provide no text for screen readers. Properly structured PDFs with tagged content can be made accessible.

7. Focus Indicators Removed

Many designers remove the default browser focus indicator (the blue outline around focused elements) because it "looks ugly". This makes keyboard navigation virtually impossible. WCAG 2.4.7 requires focus indicators to be visible.

How to Test Your Website for Accessibility

You don't need to be a technical specialist to start assessing your Cardiff website's accessibility. Here are practical approaches:

Automated Testing Tools

Start with free automated tools:

• WAVE (wave.webaim.org) — browser extension that highlights accessibility errors visually
• axe DevTools — Chrome extension from Deque, industry standard for developers
• Google Lighthouse — built into Chrome DevTools, includes an accessibility audit

Important caveat: automated tools catch roughly 30-40% of accessibility issues. They can't assess whether alt text is meaningful, whether language is clear, or whether the logical reading order makes sense. Automated testing is a starting point, not a complete audit.

Manual Testing

• Keyboard-only test: Try using your website entirely without a mouse. Can you reach everything? Is the focus order logical?
• Screen reader test: NVDA (free, Windows) or VoiceOver (built into Mac and iOS) will help you understand the experience of a visually impaired user
• Zoom test: Set your browser to 200% zoom. Does your layout break? Does text overlap?
• Colour contrast check: Use the WebAIM Contrast Checker tool to verify your text/background combinations

Involving Disabled Users

If you want to go beyond tooling, consider testing with actual disabled users. Organisations like AbilityNet and Cardiff-based disability advocacy groups can connect you with testers or provide guidance.

Making Accessibility Part of Your Cardiff Business Website

Retrofitting accessibility onto an existing website is harder than building it in from the start. If you're planning a website redesign or new build, push for accessibility to be a requirement from day one — in the brief, the design process, and the development handoff.

For existing sites, prioritise the high-impact, low-effort wins first: add alt text, fix contrast ratios, label your forms properly, and test keyboard navigation. Then work progressively through the more complex issues.

Publish an accessibility statement on your site — a page that explains your current compliance level, known issues, and how users can contact you if they encounter barriers. This demonstrates good faith and is a legal requirement for public sector organisations.

Cardiff Businesses: Where to Start

Web accessibility compliance for Cardiff businesses doesn't need to be overwhelming. Start with a WAVE audit of your homepage and key landing pages. Fix the critical errors flagged. Then engage a web professional to assess the more technical elements — keyboard navigation, ARIA implementation, semantic HTML structure.

Caversham Digital works with Cardiff and South Wales businesses to audit, remediate, and maintain accessible websites. Whether you're starting from scratch or looking to fix an existing site, we can help you meet WCAG 2.1 AA standards and turn compliance into a competitive advantage.

An accessible website is better for your customers, better for your search rankings, and better for your business. There's no good reason not to start.
