Yes i always waited for the cash back to land into my current account before i did the next switch. There is nothing to stop you from switching within say 7 days and you will get your cash back because there is no specific term and conditions with the cash backs from any of the banks. Once you draw down your mortgage you are entitled to the cash back. I was just afraid if i moved before i received the cash back they might no give it to me and i would be chasing them for ever and they might get nowhere. However never underestimate the stupidity of the banks. They probably don't check to see if you are still with them before they release the cash back. I think maybe Blackrock on here switched before he got his money back.
