In the UK we only list gambling sites that have a United Kingdom Gambling Commission (UKGC) licence. Here is some more information on what we focus on when we review an online gambling site.

Without staying aware and setting limits, a casual gambling session can easily turn into a loss of control. We recommend verifying your account and submitting the required documents before depositing to help avoid withdrawal delays. Our testing shows that cryptocurrencies such as Bitcoin, online slots Litecoin, and Ethereum generally offer the fastest withdrawals, sometimes taking as little as 15 minutes. Casinos sometimes temporarily restrict accounts while investigating unusual activity, verifying identity, reviewing responsible gambling concerns, or checking for potential violations of their terms. Confirm that your payment information is accurate, retain transaction confirmations, and contact both the casino and your payment provider if a transfer appears to be delayed or rejected.

I found that the fastest route at almost every UK casino is PayPal, as funds can arrive within hours of your request being approved. Credit cards have been banned at all UKGC-licensed sites since April 2020. Affordability checks at a £150 net loss in 30 days are a player protection requirement as well.
