I was directed to that ICO cookie banner as an example of what I need to do, by an EU law firm who we're paying to guide our compliance activities. I'm not a lawyer and I can't give you legal advice.

One potential discrepancy is that we are being prepared for the e-Privacy Regulation (which is not yet in effect), while it looks like the page you linked to covers the e-Privacy Directive.
