Check you’re on the right power plan
Not all electricity plans are created equal. Your usage might have changed since you last signed up, and the best plan for you a year ago might not be the best one now. Use Powerswitch to compare plans and providers. A few clicks could shave up to $500 off your power bills each year.*
Block out the draughts
Can you feel a breeze under the door or around the windows? That’s your heating money escaping. Seal up sneaky gaps with draught stoppers, door snakes, or weather stripping. If you have a classically Kiwi draughty house, this is one of the cheapest ways to stay warm and could cut your power bill by $100 each year.*
Switch to LED light bulbs
Still using old incandescent or halogen bulbs? LEDs use way less power and last longer. Swapping out your most-used lightbulbs can cut your lighting costs by $90 a year without sacrificing brightness.*
Clean your heat pump filter — save around $50
A clogged heat pump filter makes the system work harder (and cost more) to keep your house warm. Give it a clean each month — it’s easy, quick, and saves around $50 each year.*

Insulate to keep the heat in
A well-insulated home holds onto heat better, meaning you use less energy to stay comfortable, saving up to $340 each year.* If your house feels cold even when the heater’s on, check your insulation is 12cm deep — especially in the ceiling and underfloor. It’s one of the smartest long-term moves you can make for energy efficiency.
