Agree with you.
The thing for me is, it's always at the point of withdrawal. I just cannot see the logic as to I hit a threshold for a withdrawal. The closed loop system is in place. If it has only cost me £100. Regardless of the amount won it should be paid back to the card the money has come from in the first place.
There are two primary scenarios here:
The first, where
deposits trigger the check - you
should be alerted at the first opportunity (i.e. shortly after depositing), but some operators abuse the CDD process and wait until withdrawal (which could be weeks or months later, and the player is unknowingly anti-freerolling themselves because subsequent winnings
require a completed CDD).
Under UKGC rules, withdrawals are not supposed to be delayed if the operator could have reasonably asked for the information earlier. This predictably causes a lot of tension because the operator is in the wrong, but the UKGC are ignoring the problem.
Saying that, if you are a higher roller (e.g. £1k+ a month for a given site) then you are likely to be reviewed (including financial documentation) for responsible gambling, CDD/AML or both.

The second, where
withdrawals trigger the check (as in your case) - this is the common one where people misquote the UKGC rule above.
The handling of these cases varies wildly - some will just be a manual review (e.g. 12-48 hours instead of instant), some will ask for additional identification documents, some will start asking for additional financial information (which raises question marks - this is a
withdrawal trigger) and some will absolutely take the piss - as you sadly discovered above.
Annoyingly, the UKGC have ignored the problems here too - and operators have frequently asked for too much information, either as a faux-reversal tactic, or because they are afraid of being snagged for AML failures. The incoming rule changes should help here - but UKGC need to start enforcing action against operators abusing this process for their own benefit.
For what it's worth, with the previous changes to UKGC guidelines regarding identity documentation, it is possible to complete a withdrawal CDD (for the first time) without any additional documents. Namely because they need to verify your identity - which they have done previously - and your deposits are not sufficient to cause an AML check.
