They can in theory disconnect your services without a smart meter. However they never actually do cut you off because:
a) If there is somebody dependant on medical equipment at the address and they disconnect the electricity, they could be liable should they die as a result of being deprived of that equipment.
b) If they reconnect the gas supply while an appliance is on and there's nobody in the house, they could trigger a gas explosion.
