If you've made a transfer before and want to repeat it, you can do this automatically from 3 different places:
When you are logged in to TransferWise, click on the transfer you wish to repeat. Then choose Repeat transfer. You'll have a chance to review all the details before you confirm the transfer and pay
From the transfer page of a completed transfer. Click Repeat this transfer in the top right hand corner
From a payment confirmation page. You can access the transfer status page from the link in the email we send you when a transfer has been completed. Just click Repeat this transfer in the top right hand corner when you reach the transfer status page
This will create a transfer with exactly the same details as your previous transfer, except with the current mid-market exchange rate.
