Accessibility

Wattwise is designed for WCAG 2.2 AA

Energy information should remain usable with a keyboard, screen reader, zoom, high contrast, reduced motion, or a small touch screen.

What the interface supports

Pages use semantic landmarks, logical headings, visible focus, labeled controls, accessible errors and status messages, large touch targets, skip navigation, reduced-motion behavior, and text alternatives for chart summaries.

  • Full keyboard operation without traps
  • Synchronized readable values for sliders
  • Status is never communicated by color alone
  • Layouts reflow for mobile and browser zoom
  • Private and public routes retain correct heading hierarchy

Testing

Primary flows are checked with automated accessibility rules, keyboard navigation, responsive layouts, and rendered HTML assertions. Automated tools cannot replace human testing with assistive technology, so release review includes manual critical-flow checks.

Known limitations and feedback

Automated checks and Chromium coverage do not establish complete WCAG conformance. Future third-party provider interfaces can have limitations outside Wattwise control. Exported documents, complex charts, Safari, Firefox, mobile assistive technologies, and right-to-left presentation still require manual verification.

Use the Contact page to report a barrier. Include the page, task, device, browser, and assistive technology when comfortable; do not include private household information.
