Website Accessibility Guide for Cardiff Businesses (2026)

Here's an uncomfortable truth most Cardiff business owners haven't considered: a large chunk of your potential customers may not be able to use your website properly.

We're talking about people with visual impairments who rely on screen readers. Users with motor disabilities who navigate by keyboard rather than mouse. Individuals with cognitive conditions who need clear, simple layouts. People with colour blindness who struggle with low-contrast text.

In Wales, around 21% of the population has a disability of some kind. Nationally, disabled people and their families control an estimated £274 billion in spending power — the so-called "purple pound." If your website excludes them, you're leaving money on the table and potentially breaking the law.

This guide covers everything Cardiff businesses need to know about web accessibility in 2026: what it is, what's legally required, and how to fix the most common issues quickly.

What Is Web Accessibility?

Web accessibility means designing and building websites that can be used by everyone — regardless of their abilities, disabilities, or the assistive technologies they rely on.

The international standard is WCAG 2.1 (Web Content Accessibility Guidelines), developed by the World Wide Web Consortium (W3C). It organises accessibility requirements into four principles: Perceivable, Operable, Understandable, and Robust — often shortened to POUR.

There are three compliance levels:

• Level A — Minimum requirements
• Level AA — The standard most organisations should meet
• Level AAA — Enhanced accessibility (difficult to achieve site-wide)

For most Cardiff businesses, WCAG 2.1 Level AA is the target.

The Legal Situation for Welsh and UK Businesses

Many Cardiff business owners assume accessibility is optional. It's not — at least not legally.

The Equality Act 2010

The Equality Act requires businesses providing services to the public to make "reasonable adjustments" to avoid putting disabled people at a disadvantage. The Information Commissioner's Office (ICO) and courts have interpreted this to include websites. An inaccessible website can constitute unlawful discrimination.

Public Sector Bodies Accessibility Regulations 2018

If you deliver any public-sector services or receive public funding — think Welsh Government grants, council contracts, or NHS partnerships — you're likely covered by these regulations, which require WCAG 2.1 AA compliance and a published accessibility statement.

European Accessibility Act (EAA)

From June 2025, the EAA applies across EU member states and affects any UK business with a digital presence in European markets. It covers e-commerce, banking, transport, and consumer services. With Cardiff's strong links to European trade, this matters.

The Bottom Line

Even without specific enforcement action, an inaccessible website exposes your Cardiff business to reputational risk, complaints, and potential legal challenge. The proactive choice is to fix it now.

The Most Common Accessibility Failures (And Quick Fixes)

1. Images Without Alt Text

The problem: Screen readers can't interpret images — they read aloud the alternative text attribute instead. Missing alt text means blind users hear "image" or nothing at all.

The fix: Add descriptive alt text to every meaningful image. A photo of your Cardiff showroom should say alt="Caversham Digital's Cardiff office reception area". Decorative images should have empty alt text (alt="").

Time to fix: 30 minutes for most small sites.

2. Colour Contrast Too Low

The problem: Grey text on white backgrounds, or light text on pale coloured buttons, fails WCAG 2.1 contrast ratios. This affects users with low vision, colour blindness, and anyone viewing a screen in bright sunlight.

The fix: WCAG 2.1 AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Use the WebAIM Contrast Checker to test your colour combinations before publishing.

Common culprit: Light grey body text (#999999 on white has a ratio of 2.85:1 — that fails).

3. No Keyboard Navigation

The problem: Many users — including those with motor impairments, power users, and anyone without a mouse — navigate websites using only a keyboard (Tab, Enter, arrow keys). If your menus, buttons, and forms can't be reached this way, large groups of users are locked out.

The fix: Test your site by unplugging your mouse and navigating using only the Tab key. Every interactive element should be reachable and usable. Ensure visible focus indicators (don't suppress the browser's default outline without replacing it).

4. Form Fields Without Labels

The problem: Placeholder text in input fields is not a substitute for proper labels. When a screen reader user focuses on a field, it should announce what that field is for.

The fix: Use <label> elements properly associated with their <input> via matching for and id attributes. This takes minutes per form and makes a huge difference.

5. Videos Without Captions

The problem: If your Cardiff business uses video — testimonials, product demos, how-to guides — users who are deaf or hard of hearing miss out entirely without captions.

The fix: YouTube auto-generates captions (review and correct them). For website-hosted video, use services like Rev.com or Otter.ai to generate accurate caption files (VTT format).

6. PDFs That Aren't Accessible

The problem: Scanned PDFs, brochures, and documents are often invisible to screen readers. This is a particular issue for professional services firms in Cardiff — solicitors, accountants, consultants — who rely on downloadable documents.

The fix: Where possible, replace PDF content with accessible web pages. Where PDFs are essential, use Adobe Acrobat's accessibility checker and ensure documents are properly tagged.

Free Tools to Audit Your Cardiff Website

You don't need to spend money to get started. These tools will identify most issues in minutes:

WAVE Web Accessibility Evaluator — wave.webaim.org. Run any URL through this and it'll flag errors, warnings, and structural issues visually on the page.

axe DevTools — A free browser extension (Chrome and Firefox) that runs automated accessibility checks on any page you're viewing.

WebAIM Colour Contrast Checker — webaim.org/resources/contrastchecker. Test your specific colour combinations against WCAG standards.

Lighthouse — Built into Chrome DevTools (F12 → Lighthouse → Accessibility). Gives a score and actionable recommendations.

Screen reader testing — NVDA is free for Windows; VoiceOver is built into Mac and iPhone. Spending 10 minutes navigating your own site with a screen reader is eye-opening.

How to Publish an Accessibility Statement

If your site serves the public — especially in Wales — you should publish an accessibility statement. This doesn't have to be complicated.

Your statement should cover:

• Which standard you're aiming for (WCAG 2.1 AA)
• Known limitations and what you're doing about them
• How users can request accessible versions of content
• A contact method for accessibility issues

The Welsh Government and GOV.UK both publish accessibility statement templates you can adapt.

Making Accessibility Part of Your Process

The easiest time to fix accessibility is during a new website build, not after. If you're commissioning a new Cardiff website in 2026, ask your web design agency specifically:

• Which WCAG 2.1 level do they build to as standard?
• Do they conduct keyboard and screen reader testing?
• Will they provide an accessibility report on delivery?

A good Cardiff web design agency will treat accessibility as standard practice, not an add-on. If the answer is vague, ask for another agency's quote.

The Business Case for Accessibility

Beyond legal compliance, accessible websites simply work better for everyone. They tend to have:

• Better SEO — Search engines favour well-structured, semantically correct HTML (which accessibility requires)
• Faster load times — Accessible sites tend to be leaner and better coded
• Wider reach — You're not excluding 21% of potential Welsh customers
• Better mobile experience — Keyboard navigation and clear structure help all mobile users

Accessibility isn't a niche concern for Cardiff businesses. It's basic good practice — and increasingly, it's what customers expect.
