UK standard bank transfer. Slower than Faster Payments but reliable.
Transfer speed: 2-3 business days
Available in: UK
Kraken supports UK GBP bank deposits where transfers can be processed over Faster Payments or BACS, depending on the setup. Gemini also supports UK bank payment methods for GBP funding, but the exact method depends on your account and their banking partner.
Expect 2 to 3 business days for BACS to credit, then trading is typically available once funds land. If it is your first transfer to that exchange, a review can add extra time even if the BACS transfer has left your bank.
Limits are account-level and set by the exchange, not the BACS system alone. Kraken and Gemini publish GBP funding limits inside your account or support docs, and higher tiers usually unlock higher caps.
Missing reference codes, sending from a joint account where the exchange profile is single-name, and sending from a business account to a personal exchange profile are the common causes. If the reference is wrong, the exchange may require manual allocation.
Faster Payments is the better day-to-day rail because it is close to real-time, while BACS is slower but can be useful when Faster Payments is not available for the recipient. If speed matters, pick an exchange and deposit option that supports Faster Payments.
