I have just seen a bit of info on the U.K gambling commission site which they have tweeted. what do you think? cracking down on the sites that want I.D before cash out.
When the gambling company is checking your identity for another reason, it can freeze your account until it has confirmed who you are. There is no time limit on how long it can do this for. However, if you have asked to withdraw funds from your account, the company must not demand that you provide additional information as a condition of releasing those funds, if they could have reasonably asked for that information earlier.
