From what I’ve experienced, the biggest impact comes from rooms with large, south- or west-facing windows. I found some good guidance on https://www.tintfit.com/shop/energy-saving-insulation and here it explained which rooms get the most heat retention. In my house, the living room and kitchen benefited the most, while bedrooms saw a smaller but still noticeable difference. Starting with the areas that lose the most heat definitely makes the investment feel worthwhile.
