I’m Joe from Smarta Switch in Brisbane, and this is one of the first questions almost everyone asks: “If I switch, how long does it take, and will my power go off?” Short answers: usually within one billing cycle, and no, your power never goes off. Here’s the full picture so you know exactly what happens and when.
We’re paid by the energy retailer when you switch, never by you.
The most important thing first: switching is admin, not a physical job
When you switch retailers, nothing physical changes. No one comes to your site. No wires are touched. Your meter stays exactly where it is, the same poles and wires (your network, Energex in South East Queensland) keep delivering the power. The only thing that changes is which company bills you for the energy flowing through that meter.
That’s why there’s never an interruption to supply. You won’t lose power for a second. You’ll often barely notice the day it happens, except that your next bill comes from the new retailer at the new rate.
The real timeline, step by step
Here’s what actually happens, and roughly how long each part takes.
1. Comparison and decision, 1 to 2 days
You send your last bill, the quotes come back, you pick a retailer. With a broker this is the part that saves you the most time, because the comparing and normalising is done for you. (How quotes get compared, line by line.) Doing it yourself, expect to spend a few hours gathering and comparing quotes.
2. Sign-up and Letter of Authority, same day
You sign the new contract and, if you’re using a broker, a Letter of Authority so they can act for you and pull your meter data. This is usually a few minutes. (What an LoA does and, importantly, doesn’t authorise.)
3. Cooling-off period, up to 10 business days
Most business energy contracts come with a cooling-off period, often around 10 business days, during which you can change your mind without penalty. The switch typically won’t be actioned until this passes (or you waive it). It’s a protection, not a delay to worry about.
4. The transfer, lands on your next meter read
This is the bit people misunderstand. The actual transfer to your new retailer happens at your next scheduled meter read, not on a random date. Depending on where you are in your billing cycle, that’s anywhere from a few days to a couple of months away. For most sites the whole thing completes within one billing cycle.
If you have a smart or interval meter (common on commercial sites), the read can happen remotely and the transfer is often quicker. Older basic meters wait for the next physical read.
5. First bill from the new retailer, your following cycle
Your old retailer sends a final bill up to the transfer date. Your new retailer picks up from there. Your first new-rate bill arrives at the end of the next cycle. That’s when the savings actually show up in the bank.
So what’s the honest end-to-end number?
- Paperwork done: within a day or two of deciding.
- Switch legally locked in: after the cooling-off period, around 10 business days.
- Transfer complete: on your next meter read, typically inside one billing cycle.
- Savings visible on a bill: your first full cycle on the new plan.
Call it a few weeks end to end for a typical small commercial site, most of which is just waiting for the next meter read. The hands-on effort from you is well under an hour.
The one thing that can hold it up: your contract end date
The transfer is rarely the slow part. Timing it around your existing contract is. If you’re still locked into a fixed term, switching early can trigger an exit fee, so the smart play is usually to line the switch up for when your current deal ends.
That’s why the best time to start is 30 to 90 days before your contract expires, early enough to compare calmly and switch cleanly, late enough to quote against current market rates. (The 90-day renewal checklist walks through this.) Leave it too late and you risk rolling onto an expensive out-of-contract rate while the switch processes.
Special cases that change the timeline
- Solar or a battery on site. The switch itself is the same, but you’ll want the new feed-in terms sorted up front. (Switching with solar or a battery, explained.)
- Multiple sites. A multi-site or C&I switch runs to a tender timeline rather than a single sign-up, longer to set up, bigger to win. (How multi-site contracts work.)
- Outstanding debt or a disputed bill. A retailer can object to a transfer if there’s unpaid debt on the account. Clear it first and the switch runs clean.
- You’re mid-cooling-off on a previous switch. You can’t be transferring two ways at once. Let one settle.
What to do this week
- Find your contract end date. It’s the single biggest factor in timing, and it tells you whether to move now or diary it.
- Dig out your last full bill so a comparison can be run against your real usage.
- Start early. Even if your contract has months left, getting the comparison done now means you’re ready to switch the moment it makes sense, with zero scramble.
- Upload your bill on this page or email hello@smartaswitch.com.au. I’ll run the comparison, flag any exit-fee timing, and if it’s worth switching, handle the whole transfer so the only thing you do is sign one form. No cost, no commitment, because we’re paid by the energy retailer when you switch, never by you.
Switching sounds like a hassle. It mostly isn’t, it’s a form, a wait for the next meter read, and a cheaper bill at the end. The hard part is just deciding to look.
