You would expect a UK based organization to follow the UK ICO's guidance (https://ico.org.uk/about-the-ico/news-and-events/news-and-blogs/2019/07/blog-cookies-what-does-good-look-like/ "pre-ticked boxes or any equivalents, such as sliders defaulted to ‘on’, cannot be used for non-essential cookies" and "PECR always requires consent for non-essential cookies, such as those used for the purposes of marketing and advertising.
