5 Smart Ways to Cut Your Power Bill this Winter
Let’s face it — power bills in New Zealand can be a real budget-buster, especially in winter. But with a few smart upgrades and modern appliances, you can save a surprising amount over time. Here are 5 smart ways to cut your power bill, boost your home’s efficiency, and even add value to your property.
- Upgrade to Smart Heating and Cooling Systems
Why it works: Heating is the biggest energy user in most Kiwi homes. Smart heat pumps and thermostats allow you to heat only when and where you need to — no more blasting the whole house when you’re just using one room. Smart thermostats alone can save users between 10-12% on cooling costs per year!
Example: A smart thermostat like the Google Nest or Tado can learn your schedule and adjust the temperature automatically, so you’re not wasting power when you’re out. Some systems even let you control them remotely from your phone.
Bonus tip: If you’re using portable heaters, consider swapping them for an energy-efficient heat pump. It’ll pay off in the long run.
- Switch to LED Lighting (and Automate It)
Why it works: Traditional incandescent bulbs waste up to 90% of their energy as heat. LED lights use up to 75% less energy than incandescent bulbs.
Smart upgrade: Combine LED bulbs with smart lighting systems (like Philips Hue or TP-Link Kasa) to automate lighting schedules and turn off lights remotely. You can even set lights to turn off when no one’s in the room.
Potential savings: Households can save hundreds per year just by switching to LEDs, especially in homes with lots of lighting.
- Install Smart Plugs and Power Meters
Why it works: Some appliances keep draining electricity even when you’re not using them — this is known as “phantom load.”
What to do: Smart plugs let you cut power to devices when they’re not in use. You can schedule them to turn off at night or when you’re at work. Smart power meters, like the ones from Eve or TP-Link, can also show you which appliances are the worst offenders.
Bonus: Use the data to figure out if it’s time to replace old, inefficient devices.
- Insulate and Seal Your Home
Why it works: Heating and cooling costs skyrocket when your home isn’t properly insulated. Warm air escapes in winter, and cool air leaks out in summer.
Simple home upgrades:
- Add or top up insulation in your ceiling and underfloor (EECA even offers grants through the Warmer Kiwi Homes programme).
- Seal gaps around doors and windows with weatherstripping or draft stoppers.
- Install thermal-backed curtains or blinds.
Result: Your home stays warmer (or cooler) for longer, and your heating system doesn’t have to work as hard.
- Choose Energy-Efficient Appliances (and Check the Star Rating)
Why it works: Newer appliances are built to use less electricity — especially those with high Energy Star ratings.
Look for upgrades in:
- Fridges and freezers (they’re always on, so efficiency matters!)
- Washing machines and dryers (opt for front loaders and heat pump dryers)
- Dishwashers (many new models use less water and power per cycle)
Pro tip: Check the EECA’s Energy Rating Calculator online to compare appliances before you buy.
