For business
What you’d save a year, what the fix costs, how fast it pays back — and whether it’s yours to fix or your landlord’s. One guide covers every site you run in that industry.
Every energy use in a café, priced. What you'd save a year, what the fix costs, how fast it pays back — and whether it's yours to fix or your landlord's.
Roughly half a building's energy sits inside your tenancy. This prices every bit of it — what you'd save, what it costs, how fast it pays back, and who controls it.

Rent is fixed. Wages are fixed. Suppliers put their prices up and you wear it.
Your energy bill is different — it’s full of decisions, and most small businesses have never had anyone look at theirs properly.
The guides on this page cover what you can do yourself. If you’d rather someone did it for you, that’s what the rest of this page is.
Free · no obligation
Send a recent bill. You’ll get a straight answer on three things:
No cost. No obligation. No sales call unless you ask for one.
If there’s nothing worth doing, we’ll tell you that — it’s the most common answer we give households on our free tool, and businesses get the same treatment.

Not sure what to send? A PDF of your most recent electricity bill is enough. If you have interval data or a second site, mention it and we’ll ask for what we need.
A back-audit of 12–24 months of your bills, looking for the errors that quietly cost real money: wrong tariff assignments, meter and multiplier errors, discounts that silently expired.
Here’s exactly how it works:
Nothing to pay up front. Nothing to pay if we find nothing. Nothing to pay if the retailer won’t settle.
You only ever pay out of money you wouldn’t otherwise have had.
Forty percent sounds like a lot until you notice what it’s forty percent of: money that was gone. The alternative isn’t a cheaper consultant — it’s never seeing it at all.
This is you if: your bills have never been checked by anyone except the retailer who sent them.
We review your rates and tariff against how you actually operate — your real hours, your real load — find the plan that genuinely fits, and request the changes with your retailer so it actually happens.
This is you if: you’re on whatever plan you signed years ago, or you’ve rolled over onto a rate nobody re-checked.
Your site, your equipment, your hours, your interval data — turned into a prioritised, costed plan, with every payback computed on your numbers rather than a reference site’s.
This is you if: you want the full picture and a plan you can work through in order.
Energy managed like any other business input — monitoring, budgets, exception alerts and a clear annual plan, so the savings stick and the next opportunity doesn’t wait for the next crisis.
This is you if: you’ve fixed things before and watched them drift back.
Everything except Bill Recovery is quoted after the free bill check, once we know what we’re dealing with.
Plenty of “energy advice” in Australia is lead generation — free assessments that somehow always conclude you need the thing the assessor sells. We don’t sell hardware, we don’t take referral fees, and we’re not paid to reach any particular answer. The only person paying us is you, which is the only way the advice can be worth anything.
It’s the line we lead the whole business with, and you can check it: our published guides mark the upgrades that don’t pay back, with the working shown. A solar quote that doesn’t stack up gets told it doesn’t stack up.
Most consultants hand you a proposal and ask you to trust the numbers. We publish ours. The hour-by-hour models behind our EV and battery articles are free to download, with every assumption and source listed, specifically so you can pull them apart. When our own review found errors in one, we fixed it and said so in public.
That’s the standard the paid work is held to as well.

The same approach used to strip millions in energy costs out of large organisations, sized down for a business like yours. A café’s bill has fewer zeros than a factory’s; the discipline that finds the money is identical.
You deal with him directly — there’s no account manager between you and the person doing the work.
No — we don’t sell or install anything, and take no commissions. If solar stacks up for your site we’ll say so and tell you what to ask installers for. If it doesn’t, we’ll say that instead, which happens plenty.
The bill health check is free. Bill recovery is 40% of whatever we recover for you, and nothing if we recover nothing. Everything else is quoted after the free check, once we know what we’re actually dealing with — quoting before that would be guessing.
Then you pay nothing. We’ll tell you your bills are clean, which is genuinely useful to know, and you’re free to get on with your day.
Then you owe us nothing. We carry that risk, not you — that’s the whole point of working on contingency.
Not at present — we’re not currently registered for GST, so none is added to our fees. If that changes we’ll confirm it in writing before it affects anything you’ve agreed to.
Not for the free check. A letter of authority is only needed if we find something worth disputing and you want us to take it to your retailer — and we’ll explain exactly what it covers before you sign it.
The bill check is quick. Recovery depends on how fast your retailer moves, which is not something anyone can promise. The bigger pieces depend on how many sites and how much data exists — we’ll tell you the honest timeline before you commit, not after.
The guides cover five markets, but the paid work is Australian only for now — tariffs, rebates and market rules are country-specific, and we’re not going to pretend otherwise.
Send a recent bill. We’ll tell you whether there’s money on the table — and if there isn’t, we’ll tell you that too.
