Online casino and iGaming operators in the UK face a demanding payment landscape shaped by strict regulation and elevated fraud risk. This WebPays guide explains why casino businesses need a specialised payment gateway, covering challenges like complex UKGC rules, high chargeback volumes, money laundering exposure, and heavy transaction loads that push many providers away from the sector. It walks through how casino merchants receive funds via a merchant account and gateway, then outlines what to look for in a provider: industry experience, fair pricing, responsive support, multiple payment methods, and strong security. Since UK-issued credit cards have been banned for gambling transactions since 2020, the guide highlights compliant alternatives such as debit cards, Open Banking, and e-wallets. WebPays positions itself as a UKGC-aware processing partner for casino operators.
