Got a recent power bill? Let us read it for you

Upload your latest electricity bill (PDF or photo) and we'll fill in your power rate, daily fixed charge, retailer and usage automatically — so the audit is based on what you actually pay.
Your bill is sent to our AI partner (OpenAI) for one-off processing. We delete the original after 90 days. You can always skip this and enter the numbers manually below.

About Your Home

Who lives here?

More accurate occupancy = more accurate hot water and daytime energy estimates. Anyone home during the day uses more power.

Out 9–5 most days
Heating & lights on longer
Home from ~3pm
Home all day, more hot water

Current Systems

Got more than one? Tick all that apply — most NZ homes mix heat pump + bedroom heaters or a wood fire.

Insulation

Insulation is the cheapest and biggest win for most NZ homes — EECA estimates ceiling + underfloor insulation can cut heating bills by 30%. Not sure of your insulation? Pick your year of build and we'll fill in sensible defaults.

Frequently asked questions

Yes — completely free, no credit card, no callbacks from salespeople. Power Buddy is funded by listed installers in our directory, not by selling your details. You get a full PDF report at the end whether or not you ever request a quote.

Most homeowners finish in 5–8 minutes. You'll need rough numbers for your house size, who lives there, current heating and hot water set-up, and (optionally) your latest power bill for a more accurate estimate.

No — it's optional. If you do enter your $/month spend, the audit reconciles its bottom-up estimate with what you're actually paying, which improves the accuracy of the savings figures. Without it we use NZ-average usage for your house size, region and household.

Your annual energy use and cost, a per-room/per-system breakdown, your home's environmental impact (CO₂ and tree-equivalents), prioritised upgrades with payback estimates, available NZ government grants you may qualify for (Warmer Kiwi Homes, EECA, etc.), and a recommended upgrade order based on the NZ Energy Stack.

Only if you ask us to. After the audit you can optionally request quotes from verified installers in our directory — heat pumps, hot water, solar, insulation, EV chargers. Nothing happens automatically; you stay in control.
