"Switched in two clicks. Saved $480 a year and finally understood why my Tawa villa was costing so much in winter."
"The heat-pump sizer told me I'd been quoted 2kW too big. Saved $1,800 on the install. Genuinely independent advice."
"Used the solar tool, got matched with a great Hamilton installer. Payback came in at 6.1 years — exactly as quoted."

Common questions, straight answers.
Yes. Comparing plans, sizing your heat pump, running an audit — all free, forever. We only earn a small fee if you book a job through one of our vetted installers. We never sell your data.
No. Power Buddy is independently owned in NZ. We don't sell electricity, so we have no incentive to push you toward any specific retailer.
Not for the comparison itself — Quick Compare and the retailer calculators only need your postcode, household size, and current retailer. The optional Free Home Audit asks for your street address so we can pull the right local climate, sun-hour and frost data for your home, and the Get Pricing Today form asks for it so vetted local installers can come out and quote. We never ask for your NHI, driver's licence, IRD number or bank details, and we never sell your data.
We use live published retailer rates and your actual usage profile (or a region-matched profile if you don't have a bill handy). Estimates are typically within 5–8% of actual.
Yes — we maintain a vetted directory of NZ installers, electricians, and solar specialists. Every installer is reviewed and certified before being listed.
