The foliage is just dying back naturally, I doubt that there is anything wrong. Yes, time to cut the foliage off and lift the potatoes.

Some varieties don't flower anyway. Leaving them in so long I hope you don't find them slug eaten as my remaining few are. You can begin to dig them when the foliage begins to look a bit tired and starts dying back.
