Wise has two different services, there's "Wise accounts" where you can transfer money in, hold a balance, and transfer it out again, and then there's "Wise transfers", where you (in my case) do a US domestic wire transfer to input the dollars from a US Schwab account, and in the same operation it does a UK bank transfer to output the equivalent pounds into my normal UK Natwest account. There's a nerve-wracking hour or so in-between Schwab confirming that they've hurled the money into the void, and Wise confirming that they've received it, but apart from that it appears seamless and fairly cheap.
