Website Accessibility Compliance UK 2025: Complete Legal & Technical Guide

Website accessibility is no longer optional for UK businesses. In 2025, the legal and ethical imperatives for accessible websites are stronger than ever. This guide provides everything UK businesses need to know about accessibility compliance, from legal requirements to practical implementation.

The UK Legal Landscape for Website Accessibility

UK websites must comply with multiple legal frameworks that mandate digital accessibility. Non-compliance can result in legal action, financial penalties, and reputational damage.

Key UK Accessibility Legislation

The Equality Act 2010

The primary legislation governing accessibility in the UK. It requires businesses to make "reasonable adjustments" to ensure disabled people can access their services, including websites and digital platforms.

• Coverage: Applies to all UK businesses providing goods, services, or facilities to the public
• Protected Characteristics: Disability (affecting approximately 14 million UK residents)
• Enforcement: Individuals can bring claims to County Courts; unlimited damages possible
• Business Size: Applies regardless of company size - even sole traders must comply

Public Sector Bodies Accessibility Regulations 2018

Stricter requirements for public sector websites and mobile apps, mandating WCAG 2.1 AA compliance and requiring accessibility statements.

• Applies to: NHS, local councils, universities, government agencies
• Deadline: September 2020 (existing sites), September 2019 (new sites)
• Monitoring: Central Digital and Data Office conducts audits
• Enforcement: Equality and Human Rights Commission can take action

Recent UK Accessibility Legal Cases

Legal precedents demonstrate serious consequences for non-accessible websites:

• Domino's Pizza (2019-2021): US Supreme Court case setting global precedent; company spent millions on legal fees
• Beyoncé Website (2019): Settled accessibility lawsuit; rebuilt entire website
• UK Retailers (2022-2024): Multiple settlements (amounts confidential) for inaccessible e-commerce sites
• Average Settlement: £5,000-£25,000 plus legal costs and remediation expenses

Understanding WCAG 2.2: The Global Standard

Web Content Accessibility Guidelines (WCAG) 2.2, published October 2023, is the current international standard for web accessibility.

WCAG Conformance Levels

Level A (Minimum)

Basic accessibility features. Does not provide comprehensive accessibility. Not sufficient for legal compliance in most cases.

Level AA (Target Standard)

Recommended target for most websites. Addresses major barriers for disabled users. Required for UK public sector sites. Generally accepted as "reasonable" for Equality Act compliance.

Level AAA (Enhanced)

Highest level of accessibility. Not typically required or expected for full site compliance. Often implemented for specific content areas (e.g., healthcare information, financial services).

WCAG 2.2 Key Principles (POUR)

1. Perceivable

Information must be presentable to users in ways they can perceive.

• Text alternatives for images (alt text)
• Captions for videos
• Audio descriptions for visual content
• Adaptable content structure
• Distinguishable visual presentation (colour contrast, resizable text)

2. Operable

Interface components must be operable by all users.

• Full keyboard accessibility
• Sufficient time to read and use content
• No content that causes seizures (flashing)
• Navigation aids and clear page structure
• Multiple input methods supported

3. Understandable

Information and operation must be understandable.

• Readable and comprehensible text
• Predictable website behavior
• Input assistance and error prevention
• Clear instructions and labels

4. Robust

Content must work with current and future technologies.

• Compatible with assistive technologies
• Valid HTML markup
• Proper use of ARIA labels
• Progressive enhancement approach

New WCAG 2.2 Success Criteria (Added 2023)

WCAG 2.2 added 9 new success criteria addressing mobile accessibility, cognitive disabilities, and low vision users:

• 2.4.11 Focus Not Obscured (Minimum) - AA: Keyboard focus indicators not hidden by other content
• 2.4.12 Focus Not Obscured (Enhanced) - AAA: No part of focus indicator hidden
• 2.4.13 Focus Appearance - AAA: Visible focus indicators meet size and contrast requirements
• 2.5.7 Dragging Movements - AA: Single pointer alternative for dragging actions
• 2.5.8 Target Size (Minimum) - AA: Touch targets at least 24x24 CSS pixels
• 3.2.6 Consistent Help - A: Help mechanisms in consistent location
• 3.3.7 Redundant Entry - A: Don't ask for same information multiple times
• 3.3.8 Accessible Authentication (Minimum) - AA: Cognitive function tests not required
• 3.3.9 Accessible Authentication (Enhanced) - AAA: No cognitive function tests at all

Practical Implementation: Making Your Website Accessible

Quick Wins: Immediate Improvements (Week 1)

1. Image Alt Text

Add descriptive alternative text to all images. This is the most fundamental accessibility requirement.

• Describe the content and function of images
• Keep descriptions concise (under 150 characters)
• Use alt="" for decorative images
• Include text visible in images

2. Colour Contrast

Ensure text has sufficient contrast against backgrounds. WCAG AA requires minimum 4.5:1 ratio for normal text, 3:1 for large text.

• Test with tools like WebAIM Contrast Checker
• Pay special attention to buttons, links, and form labels
• Don't rely on colour alone to convey information

3. Keyboard Navigation

Test your entire website using only keyboard (Tab, Enter, Arrow keys). All functionality must be accessible without a mouse.

• Visible focus indicators on all interactive elements
• Logical tab order
• Skip navigation links
• Keyboard-accessible dropdowns and modals

4. Form Labels

Associate labels with form inputs using proper HTML markup.

• Use <label> elements with for attributes
• Provide clear error messages
• Include helpful instructions
• Group related inputs with <fieldset> and <legend>

Medium-Term Improvements (Month 1-2)

1. Semantic HTML

Use proper HTML5 semantic elements for structure:

• <header>, <nav>, <main>, <footer>
• <article>, <section>, <aside>
• Heading hierarchy (h1, h2, h3) without skipping levels
• <button> for buttons, not <div> with click handlers

2. ARIA Labels

Use ARIA (Accessible Rich Internet Applications) attributes appropriately:

• aria-label for elements without visible text
• aria-describedby for additional context
• role attributes for custom widgets
• aria-live for dynamic content updates

3. Video and Audio Accessibility

• Captions for all video content (required by law)
• Audio descriptions for visual information
• Transcripts for audio content
• Accessible media player controls

4. PDF Accessibility

If providing PDFs, ensure they're accessible or provide HTML alternatives:

• Tagged PDFs with proper structure
• Alternative text for images in PDFs
• Reading order defined
• Prefer HTML content over PDFs where possible
