Inside IR35 Accessibility Contract Jobs

As a contract Accessibility, you are hired to ensure that digital products, services, and content can be used effectively by people with a wide range of disabilities, including visual, auditory, motor, and cognitive impairments. Contract engagements typically involve conducting accessibility audits against WCAG 2.1 or 2.2 standards, advising product and engineering teams on remediation, embedding accessible design practices into UX and development workflows, and supporting organisations in meeting their legal obligations under the Equality Act 2010 and the Public Sector Bodies Accessibility Regulations. Demand is particularly strong within central and local government, the NHS, financial services, and large consumer-facing digital businesses.

Successful accessibility contractors combine technical knowledge with strong communication and advocacy skills. On the technical side, experience conducting audits using assistive technologies such as JAWS, NVDA, VoiceOver, and Dragon NaturallySpeaking is essential, alongside proficiency with automated testing tools such as Axe or Lighthouse. Knowledge of HTML and ARIA is expected for roles involving hands-on remediation guidance to engineering teams. Equally important is the ability to work with designers, product managers, and content teams to embed accessible practices upstream in the design process, rather than treating accessibility as a retrofit activity. A strong portfolio of audit reports and remediation programmes is the primary differentiator in this market.

Demand for accessibility contractors has grown steadily over the past three years, driven by increasing regulatory scrutiny, public sector compliance deadlines, and growing awareness among digital product teams that accessibility failures carry legal and reputational risk. The public sector remains the most active market, with many central government and NHS digital programmes requiring dedicated accessibility resource. Demand in financial services and retail is also increasing as organisations face greater pressure from regulators and customers. Supply of genuinely experienced accessibility contractors remains thin relative to demand, supporting rate levels above the broader UX market.
