If you're making a transfer in GBP to a beneficiary in the UK, there's a value cap per transfer as well as daily and weekly limits. The per-transfer limit is £250k, while the daily limit is £500k combined, meaning that you cannot transfer more than £500k out of the account per 24 hours. The weekly limit is £1,000k combined. You cannot make more than 50 transfers per 24 hours and 200 transfers per 7 days.
If you attempt to make a transfer larger than those amounts, we will re-route this transfer as it exceeds our limits and instead we will allow this transfer to be completed by another of our payment processors. Please note that in such cases your transfer might take a bit longer to arrive and will appear as from Revolut Ltd in the recipient's statement rather than from you.
