I typed "UK data watchdog" (for I did not know its name) and while it is true that I needed more clicks than for France, I found their enforcement page with their list of fines [0]: £18m here, £2m there...
They also had a massive budget shortfall which meant they sent out what amounted to a protection racket letters demanding £40 per year from every UK business, even though almost none of those businesses should be paying it.
All this while simultaneously investigating the ad industry, finding it is egregiously breaking the law, but then doing nothing about it.
The UK's ICO is taking an extremely broad definition of who should be paying it, but an extremely narrow definition of who it should enforce against.
I might add that the £40 it is demanding is almost 3 times the normal £15 yearly fee for running a business in the UK.
