i'm the same as soldier boy. I work from home. I have a fridge and a separate freezer, which I use
I have computers running constantly and loads of electronics, so my base running costs are £150 a month for electricity. Quality of life is an important factor for me, so I use what is required. If that ends up being expensive, then so be it. I think when households are obsessed with reducing costs it has a very negative impact on mental health.
