I walked away from the site on first visit due to "accept all" being the only option. Nipped back just to check after seeing your post while checking replies to my earlier comment, and wondering if the site is deliberately treating the UK differently. It turns out only-accept-all is the default and if the geolocation lookup fails (apparently that service is blocked by my pihole, it works if on mobile without home VPN) no reject option is present.
A bit of bad design there, not failing safe, if there intention is to be compliant with stricter laws, because a failure in an external dependency makes the site less compliant.
