£0 remaining for a fridge freezer

This couple, who work in the care sector on low incomes, rent their private house and the cost is high. They have had unplanned twins and only receive Child Benefit. They work shifts so one can always care for the twins. If they had a fridge freezer, they could shop more economically and batch cook food for when they come in from work. We can provide a second-hand appliance with your help. Thank you.
