I don't know the British numbers, but in Germany a car travels less than 50km per day on average, that would consume about 8kWh of electricity. You can load these 8kWh in about 8 hours at 1 kW, that is less than the load of a vacuum cleaner and much less than a kitchen stove. Incandescent lightbulbs used to consume up to 100w each. So I cannot see where a grid overload would come from, if e.g. the cooking times are mostly avoided. In general, as soon as there are enough electrical cars on the road to be noticed by the utility companies, there will be incentives to preferably load at times where the grid benefits from their consumption, as late at night, or when there is a surplus of solar energy. In this function, electrical cars can rather help supporting the grid stability.
