Same bank I’ve always had connected. Halifax on faster payments. As mentioned, transfers were under 30 minutes most recently. Now seems to have gone back to the “good ole days”
Mine have never been very fast (Santander), but that’s why it’s worth having some spare in FT ready to go (not like you’re getting any interest on it anyway!)
Transfers I make from my Co-Op current account don’t follow any pattern so I assume it’s making its way through in a queue. If I make a transfer during the night it’s in FT fairly soon after open but transfers during the day can take a couple of hours. I’ve never had to wait longer than (I think) 2.5 hours.
