- Costs vary with tariff, model, settings, load size, and household habits
Tips to Reduce Fridge-Freezer Running Costs
Set the fridge temperature to 3-5°C and the freezer to -18°C — colder than necessary wastes energy. Keep the fridge reasonably full as the thermal mass helps maintain temperature. Ensure the door seals are clean and intact.
