The cost of ignoring accessibility

In the early stages, everything can appear fine. The product launches, users start interacting with it, and unless someone explicitly raises an issue, accessibilityservice×AccessibilityFind accessibility issues early, improve usability, and build products that are more inclusive, usable, and compliant.Open service→ problems can go unnoticed. Teams focus on engagementglossary×EngagementEngagement refers to how users interact with a product, content, or experience, including actions like clicks, time spent, and interactions.Open glossary term→, conversionglossary×ConversionA conversion is any action a user takes that aligns with a defined goal, such as making a purchase, signing up, or completing a task.Open glossary term→, and performance, while accessibility sits in the background. But over time, the impact starts to surface.

Part of why it stays hidden is that the people affected rarely report it as an accessibilityservice×AccessibilityFind accessibility issues early, improve usability, and build products that are more inclusive, usable, and compliant.Open service→ problem. They report that the form did not work, or that they gave up and phoned instead, or they simply do not come back. None of that arrives labelled, so it gets absorbed into general frictionglossary×FrictionFriction refers to anything that slows users down or makes it harder for them to complete a task. It can be caused by poor design, unnecessary steps, unclear messaging, or technical issues.Open glossary term→ and attributed to something else.

Analytics compound the blind spot. The users who cannot complete a journey are, by definition, missing from the completion dataglossary×DataData is raw, uninterpreted information collected and stored so it can be analysed, processed, or used to inform decisions.

A funnelglossary×FunnelA funnel represents the stages users go through from initial interaction to completing a goal, showing how many progress or drop off at each step.Open glossary term→ can look healthy precisely because the people struggling most never make it far enough to register.

The first place it often appears is in user behaviourglossary×User BehaviourUser behaviour refers to how users interact with a product, including actions, patterns, and decision-making processes.Open glossary term→. Journeys that should be straightforward show unexpected drop-offsglossary×Drop-offDrop-off refers to users leaving a journey before completing a desired action or reaching the next step.Open glossary term→. Tasks take longer to complete. Certain groups of users struggle more than others, even if that's not immediately visible in the dataglossary×DataData is raw, uninterpreted information collected and stored so it can be analysed, processed, or used to inform decisions.

Support requests increase, often framed as confusion rather than accessibility, but rooted in the same underlying issues.

The size of the group is routinely underestimated too. Around one in five people in the UK has a disability, and that figure does not include the far larger group with temporary or situational limitations: a broken wrist, a bright screen outdoors, a noisy train, an older phone. Designs that assume ideal conditions fail all of them.

Support teams usually know before anyone else. They are the ones taking the calls that start with I could not do it online. That signal exists in most organisations already, and it is rarely routed anywhere it could influence a design decision.

In sectors like healthcare, finance, and public servicesglossary×ServiceA service is a component or function that performs a specific task within a system.Open glossary term→, accessibilityservice×AccessibilityFind accessibility issues early, improve usability, and build products that are more inclusive, usable, and compliant.Open service→ isn't optional. Regulations such as WCAGglossary×WCAGWCAG is a set of guidelines for making digital content accessible to people with disabilities.Open glossary term→, Equality Act requirements, and GDS standards exist to ensure that services are usable by everyone. Failing to meet those standards can lead to formal complaints, audits, and in some cases, legal action. What makes it more challenging is that by the time legal issues arise, the cost of fixing them is significantly higher. Changes are no longer proactive. They are reactive.

Beyond legal risk, there's a financial impact. When users can't complete journeys easily, conversionglossary×ConversionA conversion is any action a user takes that aligns with a defined goal, such as making a purchase, signing up, or completing a task.Open glossary term→ suffers. When support requestsglossary×RequestA request is an action sent from a client to a server asking for data or a service.Open glossary term→ increase, operational costs rise. When accessibilityservice×AccessibilityFind accessibility issues early, improve usability, and build products that are more inclusive, usable, and compliant.Open service→ issues require rework, development time is extended. All of these factors contribute to a higher cost of delivery, even if accessibility was never seen as a priority. The cost is just absorbed elsewhere.

Procurement is where it now tends to bite first, particularly for anyone selling into the public sector or large enterprises. Accessibilityservice×AccessibilityFind accessibility issues early, improve usability, and build products that are more inclusive, usable, and compliant.Open service→ conformance is a standard question in tender documents, and being unable to answer it credibly removes you from consideration before any conversation about the product itself.

Accessibilityservice×AccessibilityFind accessibility issues early, improve usability, and build products that are more inclusive, usable, and compliant.Open service→ is closely tied to trustglossary×TrustUser confidence that a product, service, or organisation will do what it promises.Open glossary term→. If a user can't access a serviceglossary×ServiceA service is a component or function that performs a specific task within a system.Open glossary term→, it sends a clear message about who that service is designed for, and who it isn't. In some cases, that leads to frustration. In others, it leads to disengagement. Either way, it's difficult to recover from.

Organisations rarely set out to ignore accessibilityservice×AccessibilityFind accessibility issues early, improve usability, and build products that are more inclusive, usable, and compliant.Open service→. It's usually deprioritised, delayed, or misunderstood: pushed back in favour of more visible featuresglossary×FeatureA feature is a specific piece of functionality within a product that delivers value to users.

Over time, that decision compounds, and the cost becomes harder to avoid.

Ignoring accessibility doesn't make it go away. It just delays when you have to deal with it. And the longer it's left, the more it costs to fix.
