Let me get this straight; the water came up through the drain, which would imply the soak-hole/sewer is flooded to a level above the kitchen drain hole, yet presumably the water outside isn't up to a level to seep in under the door? Odd scenario.
If this is so, then investigation into where your drain drains to is required for future reference and possible remedy.
Did a pumping station break down? Was it backflow from the council? Did the sewer system fail? Where is it? Possible compensation in the pipeline if it's the council's fault.
