Accessibility statement

Optimal Lab is committed to making this website usable by the widest possible audience, including people who rely on assistive technology, keyboard-only navigation, screen magnification, captioning, or reduced-motion settings. This statement explains the standard we aim for, where we currently fall short, and how to contact us if something on the site is preventing you from completing a task.

1. Conformance target

We design and build against the Web Content Accessibility Guidelines (WCAG) version 2.2, Level AA, published by the W3C. We treat WCAG 2.2 AA as a floor rather than a ceiling — where Level AAA is reasonably achievable for a given component we adopt it.

We align our obligations with the Equality Act 2010 (section 20 — the duty to make reasonable adjustments) and frame our roadmap around the European Accessibility Act 2025, which took effect on 28 June 2025 and applies to e-commerce services offered to consumers in the EU. Although the lab is UK-based, we intend to meet the EAA substantive requirements as a baseline for all visitors.

2. Current conformance status

This site is partially conformantwith WCAG 2.2 Level AA at the date of last review. "Partially conformant" means that some parts of the content do not yet fully conform to the standard; those parts are listed below and are in active remediation.

3. Known gaps in active remediation

The items below were identified during a structured red-team review of the site on 13 May 2026 and have committed target dates. They are listed honestly so that users relying on assistive technology can plan around them.

  • Checkout signature canvas: the consent-signature canvas at checkout is not currently operable by keyboard or screen reader. A type-to-sign alternative is being built. Target: 30 June 2026.
  • Modal focus management: the age-gate and cookie-consent dialogs do not yet trap focus or restore focus to the triggering element on close. Remediation in progress. Target: 6 June 2026.
  • Contrast tokens: a small number of secondary-text tokens in the olive palette fall below the 4.5:1 contrast ratio against their background. A palette refresh is scoped. Target: 13 June 2026.
  • Variant pickers: the product variant picker uses native radio semantics but the visual selected-state is conveyed by colour alone in one breakpoint. A non-colour indicator is being added. Target: 6 June 2026.

Each item above is tracked in our internal issue list and the target dates are commitments, not estimates. If a target slips this page will be updated within five working days with a revised date and the reason.

4. Compatibility statement

The site is designed to be compatible with the following assistive technologies in their current and immediately previous major versions:

  • NVDA (Windows)
  • JAWS (Windows)
  • VoiceOver (macOS and iOS)
  • TalkBack (Android)

It is tested against the current versions of Google Chrome, Mozilla Firefox, Apple Safari, and Microsoft Edge on both desktop and mobile. The site may not function correctly with Internet Explorer or with browsers more than two major versions behind the current release.

Where the user has enabled prefers-reduced-motion at operating system level, the site honours that setting globally — animations are either suppressed or reduced to a single non-vestibular state change.

5. How we assessed this site

The 13 May 2026 review combined two methods:

  • A 20-agent automated red-team pass over every public route, exercising keyboard traversal, ARIA roles and properties, heading order, landmark structure, form labelling, contrast measurement, and motion behaviour.
  • Manual testing by a human reviewer using NVDA on Firefox and VoiceOver on Safari, covering the registration, browse, product, cart, checkout, and account journeys.

Findings from both passes are tracked together. The gaps listed in section 3 above are the items not yet closed.

6. Feedback and contact

If you encounter an accessibility barrier on this site, or you need information from the site in an alternative format, please contact us. We treat accessibility feedback as a priority queue and aim to respond within 5 working days.

If you are not satisfied with our response you can escalate to the Equality Advisory and Support Service (EASS) at equalityadvisoryservice.com, or to the Information Commissioner's Office at ico.org.uk where the issue concerns digital service provision.

7. Review schedule

This statement was last reviewed on 13 May 2026. Substantive remediation work is ongoing through May and June 2026; this page is updated each time a listed gap closes or a target date changes. The statement is reviewed in full at least once every twelve months.
