Yes, William Hill withdrawal times can be instant with the CashDirect. It is a voucher-based payment system that allows customers to withdraw their winnings immediately at any William Hill shop. This means that once a customer has requested a payout using CashDirect, they can visit a William Hill shop and redeem their voucher for cash right away. However, it's important to note that CashDirect vouchers are only available in Pounds Sterling (GBP) and the method is currently available in the UK (excluding Northern Ireland) and Jersey.
