Accessibility Testing in the UK: Why Compliance and Commercial Growth Now Go Hand in Hand

For years, digital accessibility sat in a familiar box: the right thing to do, championed by a handful of committed teams, but rarely a boardroom priority. That box has quietly closed. Across the UK, accessibility has moved from a values statement to a legal and commercial reality that touches procurement decisions, product roadmaps, and marketing budgets alike.

This shift has less to do with a change in values than with two harder-edged forces converging: a rising regulatory floor, and a commercial case for reaching disabled customers that has become too large to ignore. For any business building or maintaining a digital product, accessibility testing has become less of a nice-to-have and more of a standard part of doing business responsibly and profitably.

The regulatory picture has changed

Businesses here have technically carried accessibility obligations for over a decade. The Equality Act 2010 places a duty on service providers to make reasonable adjustments for disabled customers, and that duty has increasingly been read to cover websites and digital services, not just physical premises. Public sector bodies have had explicit digital obligations since the Public Sector Bodies (Websites and Mobile Applications) Accessibility Regulations 2018, which require most public sector websites and apps to meet WCAG 2.1 AA (with the standard now evolving to WCAG 2.2, the current baseline referenced in accessibility guidance on both sides of the Channel).

What’s changed more recently, and what many organisations haven’t fully registered yet, is the European Accessibility Act (EAA). It came into force on 28 June 2025, and while it’s EU legislation, it reaches well beyond EU borders: any business selling qualifying products or services, from e-commerce platforms to banking services to transport ticketing, to consumers in the EU needs to meet its accessibility requirements. Being based outside the EU doesn’t exempt a company with an EU customer base, so “we’re not an EU business” is no longer a safe assumption.

Put together, this means most organisations with a meaningful digital presence are now operating under some combination of the Equality Act, sector-specific regulation, and, for those trading into the EU, the EAA. None of these obligations disappear because a business is small, and few come with a grace period long enough to build accessible practices from a standing start. The organisations in the strongest position are the ones treating accessibility as a continuous testing discipline now, rather than a compliance exercise triggered by a complaint or a legal letter.

The commercial case is larger than most businesses realise

Compliance risk gets attention in the boardroom, but it’s rarely the whole story, and it shouldn’t be. The more persuasive argument, for many businesses, is the customer base sitting on the other side of an inaccessible website.

According to the Family Resources Survey for 2023/24, an estimated 16.8 million people, around a quarter of the UK population, live with a disability. Collectively, disabled consumers and their households represent an estimated £274 billion in spending power. This is a figure often referred to as the Purple Pound. That’s not a niche market segment; it’s a substantial share of consumer spending that many businesses are inadvertently designing their way out of.

The cost of getting this wrong is measurable too. Research from the Click-Away Pound Survey found that 69% of disabled online shoppers will simply leave a website they find difficult to use because of their disability, and go elsewhere, usually to a competitor. AbilityNet has estimated the resulting cost to UK retailers at around £17.1 billion in lost online sales annually. Even allowing for how quickly the digital landscape moves, these figures point at a consistent pattern: inaccessible design doesn’t just risk a fine, it actively pushes paying customers toward competitors who have got the basics right.

There’s a broader audience effect worth naming as well. Accessibility improvements rarely benefit only the group they’re designed for. Captions help commuters watching video without sound as much as they help D/deaf users. Clear navigation and sensible contrast help an ageing population and anyone using a phone in bright sunlight, not just users with visual impairments. Many of the practices that make a product accessible also improve its search visibility, since accessibility guidelines and search engines both reward a well-structured, well-labelled content. Building for accessibility tends to build a better product for everyone who uses it.

Where testing comes in

None of this happens by accident, and it doesn’t happen through good intentions at the design stage alone. Accessibility is a quality attribute and it has to be tested, not assumed. A visually appealing interface can still be unusable with a screen reader. A form that looks fine to a sighted user can be impossible to complete with keyboard-only navigation. These are the kinds of gaps that structured accessibility testing, combining automated scanning with manual and assistive-technology testing, is designed to catch before customers or regulators do.

That’s the practical side of this conversation, and it’s substantial enough to deserve its own discussion: what accessibility testing involves, where automated tools fall short, and how testing fits into a healthy delivery pipeline rather than a pre-launch scramble. We’ll cover that in the next post in this series.

For now, the takeaway is simpler. The regulatory case for accessibility testing has firmed up, the commercial case was already strong and keeps growing, and the businesses treating this as an ongoing discipline today are the ones best placed to avoid both the compliance risk and the lost revenue tomorrow.
