Website Accessibility Standards in the UK

If your business has a website, you need to know about accessibility. UK law now expects websites to be usable by everyone – including those with disabilities. But what actually counts as accessible? What does the law require, and what happens if you get it wrong? This guide demystifies UK website accessibility standards, explains your legal duties, and shows exactly how to make your site compliant, practical, and welcoming to all.

Website accessibility means designing and building your site so that people with disabilities can use it just as effectively as anyone else. This includes users who are blind or partially sighted, deaf or hard of hearing, have mobility or dexterity challenges, or experience cognitive or learning differences. Accessibility isn’t just about ticking boxes – it’s about ensuring your business is open to everyone and not excluding potential customers or clients.

In the UK, over 14 million people are disabled, according to the Office for National Statistics (ONS, 2023). That’s more than one in five of your potential customers. If your website isn’t accessible, you’re not just risking legal trouble – you’re turning away a huge portion of the market. Accessibility also improves SEO, user satisfaction, and reputation. It’s fundamentally good business sense as well as a legal requirement.

Ignoring accessibility can lead to complaints, negative press, and even legal action. The Equality Act 2010 specifically requires businesses to make ‘reasonable adjustments’ to ensure disabled people are not disadvantaged – and this extends to websites. The government also sets specific accessibility standards for public sector bodies, which influence best practice for everyone. In short: accessibility is no longer optional, and the bar is rising every year.

The primary law covering website accessibility in the UK is the Equality Act 2010. This landmark legislation replaced the Disability Discrimination Act and makes it unlawful for service providers – including most businesses – to discriminate against disabled people. The law applies whether your business is a sole trader, partnership, limited company, or charity.

You are required to make ‘reasonable adjustments’ to ensure your website is accessible. What counts as ‘reasonable’ depends on your size, resources, and the nature of your business. However, the expectation for basic accessibility is now high, and ‘I didn’t know’ is not an acceptable defence. The law is enforced by the Equality and Human Rights Commission (EHRC), and individuals can also bring claims against your business if they are unable to use your website.

If you operate in the public sector or supply goods or services to public bodies, you also need to comply with the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018. These set a higher, more specific bar: public sector sites must meet the WCAG 2.1 AA standard and publish an accessibility statement. While private businesses aren’t directly bound by these regulations, they are considered the benchmark for ‘reasonable adjustments’ under the Equality Act.

In practical terms, the UK Government and the EHRC refer to the Web Content Accessibility Guidelines (WCAG) as the de facto accessibility standard. The current required level for public sector sites is WCAG 2.1 AA, published by the World Wide Web Consortium (W3C). For private businesses, meeting WCAG 2.1 AA is considered a strong defence if your accessibility is challenged.

WCAG is a technical standard, but it boils down to making your website perceivable, operable, understandable, and robust for all users. The AA level includes requirements such as providing text alternatives for images, ensuring sufficient colour contrast, making all functionality available from a keyboard, and clear labels for forms. While WCAG 2.2 was released in late 2023, most UK guidance still references 2.1, but adopting 2.2 is increasingly recommended for futureproofing.

The UK Government Digital Service (GDS) also publishes practical guidance and checklists for meeting accessibility requirements. If you’re working with web developers, designers, or agencies, always specify 'WCAG 2.1 AA compliance' in your brief or contract. This is the recognised UK standard and the benchmark in any legal dispute.

The WCAG standard is built around four core principles: Perceivable, Operable, Understandable, and Robust – often called the ‘POUR’ principles. These are practical, not just technical, and are relevant for any small business owner looking to make their site accessible.

Perceivable means that all content must be presented in ways users can sense – for example, providing text descriptions for images so screen readers can convey the information to blind users. Operable means users must be able to navigate and use your site using a keyboard, not just a mouse. This is critical for people with mobility impairments or vision loss.

Understandable means your content and navigation should be clear and predictable – for example, using plain English, consistent layouts, and clear instructions. Robust means your site should work reliably across current and future technologies, including assistive devices like screen readers and speech recognition software. Failing on any of these principles can make your site inaccessible to a significant number of users.

• Perceivable: Text alternatives for images, captions for videos, readable fonts
• Operable: Full keyboard navigation, no time limits, clear focus indicators
• Understandable: Plain language, clear instructions, consistent navigation
• Robust: Compatible with assistive technologies and future browsers

Even well-intentioned small business sites often fall short of accessibility standards due to common, avoidable mistakes. One of the most frequent issues is missing or poor-quality alternative text (alt text) for images. Without meaningful alt text, blind users cannot understand the content or purpose of images, logos, or buttons. Another widespread problem is insufficient colour contrast, making text unreadable for users with visual impairments or colour blindness.

Many sites are built with mouse users in mind, neglecting keyboard navigation. If menus, forms, or pop-ups cannot be accessed or completed using only the keyboard, users with mobility or vision challenges are locked out. Similarly, poorly labelled form fields and buttons can leave users guessing what information is required or what will happen when they click a button. Uncaptioned videos and audio files exclude deaf or hard-of-hearing users.

Complex language, jargon, and inconsistent navigation also create barriers for users with cognitive or learning disabilities. Inaccessible PDFs, unresponsive layouts on mobile, and lack of error identification in forms can all turn away potential customers. Addressing these issues is often a matter of small, practical adjustments – but you need to know what to look for.

• Images without descriptive alt text
• Low contrast between text and background
• Menus and forms that don't work with keyboard only
• Uncaptioned video or audio content
• Confusing or inconsistent navigation structures
• Links that aren’t descriptive (e.g. 'click here')

Making your website accessible is not a one-off project but an ongoing process. However, you can make huge improvements with a structured approach. The first step is to audit your current website: use both automated tools and manual testing to identify obvious barriers. Enlist real users with disabilities if possible – their feedback is invaluable and often reveals issues you’d never spot yourself.

Next, prioritise fixes that have the biggest impact on user experience and legal compliance. Start with text alternatives for images, ensuring keyboard navigation, fixing colour contrast, and adding captions or transcripts for multimedia. Review all forms for clear labels, logical order, and accessible error messages. Make sure your website template or CMS is up to date and supports accessibility features. If you rely on third-party plugins or templates, check they’re compliant or replace them if not.

Document your actions and improvements. For public sector contracts or larger businesses, publish an accessibility statement explaining your level of conformance, known issues, and contact details for users who need help. Finally, ensure accessibility is considered in all future updates, content uploads, and design changes. Make it part of your website maintenance routine rather than a one-time fix.

If you’re building or overhauling your website, platform choice makes a huge difference. Many popular UK website builders (like Wix, Squarespace, Shopify, WordPress.com) claim to offer accessible templates – but not all are equal, and much depends on how you use them. Always check for up-to-date WCAG 2.1 AA compliance, particularly for themes and plugins. Avoid platforms that don’t support keyboard navigation, alt text, heading structure, or form labelling.

When hiring a web developer or agency, ask for specific experience with UK accessibility standards and examples of accessible sites they’ve built. Include accessibility in your project brief and contract, specifying at least WCAG 2.1 AA compliance. Don’t be afraid to ask how they test accessibility, what tools they use, and whether they include user testing with disabled people.

For content management, train staff and contributors in basic accessibility principles: using plain English, adding alt text, checking contrast, and avoiding inaccessible media. If you use PDFs or downloads, ensure they are accessible or provide alternatives. Accessibility is a team effort, not just a technical one.

• Check theme and plugin accessibility before choosing a platform
• Specify accessibility requirements in contracts and briefs
• Request evidence of accessible sites from agencies or freelancers
• Train all staff who add content on basic accessibility principles
• Test sites on multiple devices and with assistive technologies

Website accessibility is increasingly enforced in the UK. The Equality and Human Rights Commission (EHRC) can investigate businesses suspected of breaching the Equality Act. In serious cases, this can lead to legally binding agreements, court orders, or even unlimited fines. More often, businesses face complaints or legal claims from individuals who cannot access their websites.

A typical scenario is a user with a disability contacting you to report an accessibility barrier. If you fail to respond or refuse to fix it, they can escalate to the EHRC or take legal action in the County Court. Even if no fine is issued, you could be forced to pay compensation, legal costs, and – crucially – fix your website anyway. The reputational damage from bad publicity or negative reviews can be far greater than any fine.

Public sector bodies have faced enforcement notices and investigations from the Government Digital Service (GDS) and the Central Digital and Data Office (CDDO). Private businesses are not immune: as awareness grows, more disabled users are exercising their rights. Don’t wait for a complaint – the cost and hassle of retrofitting accessibility far outweigh doing it right the first time.

Accessibility is especially important for e-commerce sites. If someone with a disability cannot complete a purchase, you risk both legal claims and lost sales. Common barriers include inaccessible checkout forms, unclear error messages, and product images without alt text. Ensure your shopping cart, payment gateway, and all forms work with a keyboard and screen reader.

For small businesses, the key is to focus on the areas that matter most to your customers. This means prioritising your homepage, contact page, and any critical forms. If you operate in a niche (such as education, healthcare, or services for disabled people), the expectation for accessibility is even higher. For charities and community groups, meeting WCAG 2.1 AA is increasingly seen as essential, not optional.

Remember, accessibility isn’t just for new sites. If your website is more than a couple of years old, schedule a review and plan for improvements. Even simple changes, like adding captions to videos or making buttons more descriptive, can make a big difference. Accessibility should be seen as an investment in your business’s long-term success.

• Test your checkout process with a keyboard and screen reader
• Check all images and buttons have meaningful alt text
• Review form labels, error messages, and instructions
• Ensure critical pages (contact, about, products) are fully accessible
• Update and test old content, especially PDFs and downloads

Accessibility is not a set-and-forget job. Every time you add a new page, upload an image, or update your theme, you may introduce new barriers. Make accessibility part of your website update checklist. Use tools like Siteimprove, Axe, or WAVE to regularly scan your site, but always supplement with manual checks.

Train all staff who add or edit website content in basic accessibility principles. This includes writing alt text, using proper heading structure, checking colour contrast, and avoiding jargon. Many accessibility errors are introduced through content, not code – for example, uploading a PDF that isn’t tagged for screen readers, or embedding a video without captions.

Schedule a full accessibility review at least once a year, or whenever you make major changes to your site. Document your checks and improvements: this shows you are making ‘reasonable adjustments’ if challenged. If you outsource your web management, ensure your supplier is contractually responsible for accessibility, and check their work regularly.

• Include accessibility in your website update checklist
• Train staff on writing alt text, headings, and accessible content
• Regularly use both automated and manual accessibility checks
• Document all accessibility audits and improvements
• Hold web suppliers accountable for accessibility standards

There’s no need to reinvent the wheel when it comes to accessibility. The UK Government Digital Service (GDS) offers clear, practical guidance for small businesses and charities, including checklists and templates. The British Standard BS 8878 (Web Accessibility – Code of Practice) is a useful framework for managing web accessibility, especially for non-technical owners.

The Equality and Human Rights Commission (EHRC) provides legal guidance and can advise on what counts as a ‘reasonable adjustment’. For technical questions, the W3C’s WCAG quick reference guide is the gold standard. The Federation of Small Businesses (FSB) and AbilityNet offer webinars, factsheets, and low-cost audits for small businesses. Local charities and access groups may also provide user testing and feedback services.

It’s also worth joining online communities such as the UK Web Accessibility Meetup or LinkedIn groups focused on digital inclusion. If you’re unsure about your legal obligations, consult a solicitor with experience in Equality Act claims. Investing in professional advice or an audit can save you far more than the cost of a legal claim or lost business.
