Just a heads up for anyone else who’s also in the unlikely position to get money back from the government.
I’ve just had HMRC reject my starling bank account for a tax refund. I got a cheque instead…
After calling HMRC they manually accepted my starling account, but by that point I’d already sent the cheque to the ops team.
I suggest you call HMRC to double check they’re happy with your starling account.
