Fastest way to convert and withdraw yo UK GBP bank account?

I've got around £2000 in different crypto in Binance, which my plan was to convert all to USDT and then send to kraken Pro then convert to GBP and withdraw. Never done it before but just wondered how long it may take or if there's a quicker way. I've heard something about kraken holding onto funds when you try to withdraw for a few days, is that true? I need the money by Monday at the latest ideally.
