Only the relatives can try to get the settings to a more economic usage. My experience is that because relatives have no financial involvement they are just not interested!
It decreases the relatives' inheritance!
I must disagree with my learned friend, reducing heating costs will enable more money to be saved so it will INCREASE inheritance.
I should have said it affects the relatives' inheritance, so they will have a financial involvement.
That property is grossly oversized for one person.
It may be. But, fortunately we do not live in a country where the government dictates what size property you are allowed to live in.
A few years ago we (4 people) were living in a 5 bed Edwardian semi. A Vietnamese student came to live with us for a year. Her first words, as she entered our house for the first time were: "Only
four people live in this large house?!" We later found that she and her family, including grandparents lived in a two room flat with hot water once or twice a week. She spent 45 minutes in our shower for the first few nights!
