Ok, so 4 hours - about the same timeframe as my business transfers arrived in.
It certainly seems that Faster Payments have some kind of lag, from my limited experience.
Revolut team members - could you confirm if this is the case? Is the limit self-imposed (i.e you are running some kind of fraud checks and/or manually confirming), or is it technical - e.g you are updating balances, say, every few hours?
Would appreciate knowing the details, as I believe there’s a wider expectation now that UK -> UK bank transfers will be near enough instant.
