How this checklist is scored
Each of the 20 checklist items is worth 5 points, split evenly across four categories: lighting, appliances, insulation, and water heating. Consequently, your final score out of 100 shows not just how efficient your home is overall, but which specific category needs the most attention.
What your score means
A score of 80 or above means your home is already highly efficient, with only minor tweaks left to make. A score between 60 and 79 is good but leaves meaningful savings on the table. However, a score below 60 usually means you are overpaying on your electricity bill every single month, and below 40 signals significant, easily fixable waste.
Where to start if your score is low
Begin with the category that scored lowest, since that is where the fastest savings usually come from. Switching remaining bulbs to LED and cleaning AC filters are typically the cheapest fixes with the quickest payback. Additionally, if electricity costs are your biggest concern, use our Solar Panel Savings Calculator to see if rooftop solar makes sense for your home, and check your overall footprint with our Carbon Footprint Calculator.
Frequently Asked Questions
How accurate is this home energy audit checklist?
It is a self-assessment based on common efficiency practices recognised across lighting, appliances, insulation, and water heating. Therefore, it is a strong starting point for identifying waste, though a professional energy audit can measure actual consumption more precisely.
What is a good home energy efficiency score?
A score of 80 or higher out of 100 indicates a highly efficient home. Scores between 60 and 79 are good but improvable, while anything below 60 usually points to noticeable, fixable energy waste.
Which category usually offers the biggest quick win?
Lighting and appliances typically offer the fastest, cheapest wins, since switching to LED bulbs and unplugging idle electronics costs very little. In contrast, insulation and solar water heating deliver bigger savings but need more upfront investment.
How often should I redo this energy audit?
Once every six to twelve months is enough for most households, or right after any major appliance purchase, renovation, or house move. As a result, you can track whether your efficiency improvements are actually holding up over time.
