Focus not obscured (minimum)
When someone tabs through the page, the focused element must not be hidden behind a sticky header, cookie bar or chat widget.
In practice: Sticky practice headers and live chat bubbles are the usual culprits on GP websites.
Dragging movements
Anything that works by dragging needs a single-pointer alternative.
In practice: Affects carousels and map controls used on 'find us' pages.
Target size (minimum)
Interactive targets need to be large enough to hit reliably, with spacing between them.
In practice: Matters on appointment and prescription buttons used on small phones.
Consistent help
Help mechanisms — contact details, chat, help links — should appear in the same relative place on every page.
In practice: Put the reception phone number in a consistent position sitewide.
Redundant entry
Do not make people re-enter information they have already given in the same process.
In practice: Applies to multi-step registration and feedback forms.
Accessible authentication (minimum)
Do not require a cognitive test such as remembering a puzzle to log in.
In practice: Relevant where a patient area or online form sits behind a login.
