Website Accessibility for Small Business: Legal Guide

Most small business owners in Surrey ask the same thing when we scope a new site: “Do I actually have to worry about accessibility, or is that just for big companies?” The short answer is yes: accessibility applies to small businesses too. And getting the basics right is easier and cheaper than most people expect. Here’s what the law says, what actually matters, and how to fix the common problems.

Key takeaways

• Yes, UK small businesses are covered. The Equality Act 2010 requires you to make “reasonable adjustments” so disabled people can use your services, and that includes your website. There’s no small-business exemption.
• The standard to aim for is WCAG 2.2 Level AA. It’s the internationally recognised benchmark and what UK courts and the public sector treat as the reference point.
• Around 1 in 5 UK adults report a disability (roughly 16 million people, per government figures), so an inaccessible site is quietly turning away real customers, not just risking a complaint.
• The biggest wins are usually simple: colour contrast, real text labels on buttons and links, keyboard navigation, and alt text on images. These fix the majority of issues most small sites have.
• Automated checkers catch about 30-40% of problems. The rest need a human to test with a keyboard and a screen reader. Automated tools are useful, but they can give false confidence on their own.
• If you sell to consumers online, the European Accessibility Act (June 2025) can reach you even as a UK business if you serve EU customers.

Do small businesses legally need an accessible website in the UK?

Yes. Under the Equality Act 2010, any business providing goods or services to the public must make “reasonable adjustments” for disabled people, and the Equality and Human Rights Commission has confirmed this extends to websites. There is no carve-out for small companies.

What “reasonable” means depends on your size and resources. A solo tradesperson is not held to the same bar as a national retailer. But “reasonable” does not mean “do nothing.” If a wheelchair user couldn’t get through your shop door, you’d fix it. A blind customer who can’t complete your contact form is the digital version of the same problem.

Two other rules matter depending on who you serve:

• Public sector bodies (and anyone building sites for them) must meet the Public Sector Bodies Accessibility Regulations 2018, which mandate WCAG 2.2 AA and a published accessibility statement.
• The European Accessibility Act came into force in June 2025. If you sell products or services online to consumers in the EU (common for e-commerce), you can fall within scope even from the UK.

For most Surrey small businesses, the practical takeaway is simple: aim for WCAG 2.2 AA. It puts you in a stronger position under the Equality Act, helps prepare you for the EAA, and future-proofs the site if you ever bid for public sector work.

What is WCAG and which level should a small business aim for?

WCAG, the Web Content Accessibility Guidelines, is the global standard for accessible websites.

For most small business sites, the level to target is 2.2 Level AA. It is what the UK public sector uses, what courts refer to, and what accessibility auditors test against. The full standard is published free by the W3C, so you can read the WCAG 2.2 success criteria yourself rather than take anyone’s word for it.

WCAG has three levels:

Level	What it means	Should you target it?
A	Bare minimum. Fixes total blockers.	Not enough on its own
AA	The practical standard. Covers contrast, navigation, forms, text sizing.	Yes, this is your target
AAA	Gold standard. Some criteria are impractical for general sites.	Only for specific pages, not site-wide

The guidelines are organised around four principles, easy to remember as POUR: content must be Perceivable, Operable, Understandable, and Robust. In plain English: people can perceive the content, operate the site in the way they need to, understand what things do, and rely on it working across browsers and assistive technology.

What are the most common accessibility mistakes on small business websites?

The same handful of problems show up on most small business sites we audit, and they’re almost all inexpensive to fix. Here are the ones worth checking first.

1. Poor colour contrast. Light grey text on white, or pale text over a photo, fails the WCAG contrast ratio of 4.5:1 for normal text. This is the single most common failure. Test it with the free WebAIM Contrast Checker before you sign off any colour scheme.

2. Images with no alt text. Screen readers announce images using their alt attribute. A product photo labelled “IMG_4821.jpg” tells a blind customer nothing. Describe what the image shows and why it’s there. Our guide to writing alt text that works for people and search engines covers how to do it well.

3. Vague link and button text. Links that only say “click here” or “read more” are unhelpful out of context, because screen reader users often navigate by pulling up a list of links. Write “Download our 2025 pricing guide” instead. The same principle applies across your site, as we cover in our small business website copywriting guide.

4. Can’t use it with a keyboard. Many disabled users never touch a mouse. Try tabbing through your own site. If you can’t reach every menu, link, and form field with the Tab key, and see a visible highlight showing where you are, that needs fixing.

5. Forms without labels. Placeholder text that vanishes when you start typing isn’t a label. Every field needs a proper, persistent label that assistive tech can read.

6. Video with no captions. Auto-generated captions are a start, but they need checking. Missing captions shut out deaf and hard-of-hearing visitors entirely.

7. Skipped heading levels. Headings should nest logically (H1, then H2, then H3). Screen reader users navigate by headings the way sighted users skim. Jumping from H2 to H5 breaks that map.

How do you make a small business website accessible? A practical process

Start with the simple, high-impact fixes. Then test with real assistive technology and publish an accessibility statement. You do not need to fix everything at once. You need to make steady, documented progress, which is exactly what “reasonable adjustments” means in practice.

Here’s the process we use:

1. Run an automated scan first. Tools like WAVE, axe DevTools, or Google Lighthouse flag obvious problems in minutes and cost nothing. Fix everything they surface, but know this only catches roughly 30-40% of issues.
2. Test with a keyboard. Unplug your mouse and try to complete your main tasks: navigate the menu, read a page, fill in the contact form, check out if you sell online. Every step must work and the focus indicator must always be visible.
3. Test with a screen reader. Turn on VoiceOver (built into every Mac and iPhone) or NVDA (free on Windows) and listen to your homepage and a key page. This is where you catch the problems automated tools miss.
4. Fix the content and code issues. Add alt text, rewrite vague links, add form labels, correct heading order, and raise contrast where it fails.
5. Publish an accessibility statement. A short page saying what standard you aim for, known limitations, and how someone can contact you if they hit a barrier. This demonstrates good faith, which matters legally.

If you’d rather not work through this yourself, our website accessibility audit and fix service covers the whole process and gives you a prioritised list of what to change and why.

Accessibility overlaps heavily with things you should be doing anyway. Clean heading structure, fast pages, and mobile-friendly layouts all help. See why mobile-first website design matters and how a fast-loading business website wins. Both feed directly into an accessible, usable site.

Does accessibility actually help your business, or is it just a legal box to tick?

It helps your business, and this is where we part ways with the “compliance-only” view. Accessibility is not just a legal chore. An accessible site is a better-selling site.

Clear labels, logical structure, and readable text reduce friction for everyone, not just disabled users. A form that’s easy for a screen reader user to complete is easy for a distracted parent on a phone too. That’s why accessibility and conversion work pull in the same direction. See our guide to website conversion optimisation for small business.

There is an SEO benefit too. Alt text, proper headings, descriptive links, and clean semantic code all help search engines understand your site. The same work that helps a screen reader helps a search crawler, which is why accessibility sits alongside the basics in our small business SEO checklist.

And the market is bigger than most owners realise. With around 16 million disabled people in the UK controlling significant spending power (the so-called “purple pound,” estimated at over £270 billion a year), an inaccessible checkout is lost revenue, not just risk.

When should you build accessibility in versus retrofit it?

Build it in from the start, because retrofitting usually costs more. Fixing contrast, labels, and structure on an existing site is doable, but rebuilding a template that was never designed with accessibility in mind can mean redoing large parts of it.

If your current site is more than a few years old, was built on a cheap drag-and-drop template, or you’re already thinking about a refresh, fold accessibility into that project rather than bolting it on later. Our small business website redesign guide walks through when a redesign makes sense and what to prioritise. Doing accessibility during a planned redesign can keep extra cost low, because you are making the decisions once instead of twice.
