We're currently trying to sell a house and it has been empty since November. We timed the gas to come on for about an hour in the morning and hour and a half-ish at night during the winter to keep the house warm and pipes to not burst. My DH has just told me we've had a bill for £700!!!!! After picking myself off the floor I had to ask is this normal to have such a high bill. FOR A HOUSE WHERE NOBODY LIVES ie EMPTY! Maybe this is perfectly normal. We have oil at the moment and deco don't spend that much. With actual people living in the house.
