To deposit GBP your Coinbase account, you have several convenient options. You can use a bank transfer via Faster Payments, which typically takes a few minutes to complete. Simply link your UK bank account to your Coinbase account, initiate the transfer from your bank, and ensure you use the unique reference code provided by Coinbase to avoid delays. Alternatively, you can deposit using a debit card for instant availability of funds, though this may incur a small fee. Always check Coinbase's support page for the latest details on fees and processing times.
