Generally we see two types of outcomes from our work:
First is the home where the family already uses the whole house and their bills are very high. After retrofit, their bills plummet. We have had homes that reduce running costs by 65%, saving over €5,000 a year.
Second is the home where the family saves money on bills by piling on extra clothes and living mainly in the kitchen because the rest of the house is so cold. After retrofit, cost savings are minimal, but now they use the entire house because it’s so comfortable and warm, and they don’t have to bother with extra clothes.
