UK public sectorAA

WCAG 2.2 standard in UK public-sector guidance

Government guidance says public-sector websites and mobile apps should meet WCAG 2.2 AA, subject to applicable legal exceptions.

Important limitation Automated testing cannot detect every accessibility failure. Absence of automated errors does not prove WCAG conformance.

Mobile web design statistics

Some UK adults are smartphone-only

Ofcom data shows why a responsive layout cannot be treated as an optional enhancement.

Online UK adults

20% rely solely on a smartphone for internet access

For this group, the mobile experience is the website experience. Navigation, forms, checkout and content all need to work comfortably on a phone.

All UK adults

6% do not have internet access at home

Digital exclusion is concentrated among older and lower-income groups, reinforcing the importance of accessible and efficient digital services.

Ecommerce UX

Cart abandonment remains a major design problem

Baymard Institute currently calculates an average cart abandonment rate of 70.22% from 50 documented ecommerce studies. It is an aggregated global benchmark, not a UK-only statistic.
