See where your home loses energy and estimate the savings from upgrades. Answer a few questions about insulation, windows and heating, get an efficiency score with a breakdown, and compare the payback of improvements. Planning estimates only.
See where your home wastes energy and estimate the savings from smarter insulation, heating and cooling — free.
Energy is one of the biggest ongoing costs of owning a home, and much of it leaks away invisibly. Our free home energy efficiency analyzer helps you understand where your house loses the most energy and estimate how much you could save by improving insulation, sealing gaps and upgrading heating and cooling.
Small inefficiencies add up over years. A poorly insulated roof, draughty windows or an oversized heating system quietly inflate every bill. By estimating the impact of improvements before you make them, you can prioritise the upgrades that pay back fastest instead of spending on changes that barely move the needle.
Estimate how much energy your climate control uses and where it's wasted.
See how better insulation could cut your heating and cooling bills.
Understand how draughts and gaps drive up your energy costs.
Prioritise upgrades by their likely payback.
The analyzer helps you compare where your money is going and where an upgrade would help most. Insulation, air sealing, efficient appliances and right-sized heating and cooling each play a role — and knowing their relative impact lets you plan improvements in a sensible order.
Common high-impact steps include improving insulation, sealing air leaks, upgrading to efficient appliances and right-sizing heating and cooling. The analyzer helps you estimate each one's impact.
Acting on the biggest sources of waste typically reduces bills. The tool helps you find those sources and prioritise upgrades.
