From the audit of their public home page on 23/10/2026, worst first. Each links to what it means and how it is fixed.

• high
  Insufficient color contrast ratio

  Low contrast text is difficult or impossible to read for users with low vision, color blindness, or in bright ambient lighting.

• high
  Missing landmark elements

  Duplicate IDs cause label elements, aria-labelledby, aria-describedby, and fragment link targets to associate with the wrong element.

• medium
  Excessive DOM size

  A large DOM tree directly impacts Interaction to Next Paint (INP), a Core Web Vital.

• medium
  Form inputs missing associated labels

  Unlabelled form fields are unusable for screen reader users, who represent a significant portion of potential customers.

  Form inputs missing autocomplete attribute

  WCAG 1.3.5 requires input purpose to be programmatically determined for inputs collecting user information.
