Cost-Effective Cooling For Summer

When the summer heat strikes, running an air conditioner can send power bills through the roof. But did you know a well-insulated home can save you money while keeping you cool and comfortable?


Proper insulation doesn’t just help in winter—it’s the secret to cost-effective cooling during summer too!

How Insulation Saves You Money

Insulation minimises heat transfer, which means keeping the summer heat out and winter warmth in. This reduces the need for excess cooling and heating systems, helping you save on electricity bills every month.


Real-Life Example: A typical three-bedroom Kiwi home could save up to $600 annually on energy bills after an insulation upgrade. With the Warmer Kiwi Homes grant, the cost of insulating this home might be as low as $200—meaning the upgrade pays for itself in just a few months.

What Does Insulation Cost?

The cost of insulation varies depending on your home’s size and areas to be insulated (ceiling, walls, underfloor). Here’s a rough estimate:

  • Ceiling insulation: $3,000 - $5,000 for an average home.
  • Underfloor insulation: $2,000 - $4,000 for most homes.
  • Wall insulation (if needed): $5,000 - $15,000 depending on accessibility.

These costs can feel significant upfront, but with the Warmer Kiwi Homes grant, you may be eligible for 90-100% off insulation upgrades, drastically reducing your out-of-pocket expenses—or even making the upgrade free.

Why Insulation Is Worth It

Insulation isn’t just about cutting energy bills—it’s an investment that pays off in many ways:

  • Lower Energy Usage: Your cooling and heating systems run less frequently, significantly lowering your electricity bills.
  • Year-Round Comfort: Enjoy cooler summers and warmer winters with consistent indoor temperatures.
  • Healthier Living: Insulation reduces dampness, condensation, and mould, creating a healthier and more comfortable home environment.
  • Boosted Home Value: A well-insulated home is more appealing to buyers should you decide to sell.
  • Long-Term Savings: Well-insulated homes can reduce energy costs by 20-40%, which could save you hundreds—or even thousands—of dollars annually.
