Smart meter installation: the day itself, and the one thing that can stop it

Most smart meter installations are dull, which is the correct outcome. Your retailer gives you at least four business days' notice, an installer arrives inside a named window, your power goes off for somewhere between 30 minutes and two hours, and a new meter goes on the wall. You usually do not need to be home. The part worth reading properly is the small minority of visits that stop halfway, because when that happens the cost lands on you rather than on your retailer, and almost nothing published about the rollout says so.

The outage window, in real numbers

Retailers publish different figures because the job genuinely varies. The honest answer is a range rather than a single number, and the range is wider than the "about an hour" you will often see quoted.

Published retailer guidance spans from under 30 minutes to up to two hours. Plan against the top of the range, not the bottom, and treat anything that must not lose power as your problem to solve in advance.

The thing that aborts an install, and why it costs you

This is the single most expensive surprise in the whole rollout and it is almost absent from official material, which is written from the position that the meter exchange is free. It is: the meter is free. The precondition for fitting it is not.

Things that commonly stop a visit:

• Asbestos backing board. Common in Australian homes built before the 1990s. It cannot simply be drilled into, so the panel needs replacing by someone licensed to handle it.
• A defective or overloaded switchboard, including old ceramic fuses, damaged enclosures, or no room to fit the new meter.
• Deteriorated service wiring at the point of attachment, which is a Level 2 job by definition.
• An inaccessible or unsafe location, including a box behind a locked structure or overgrown by vegetation.

We are deliberately not publishing a dollar figure for remediation, because it depends entirely on your board, your property and who does the work, and a made up range would be worse than no range. What we would say is: if your house predates the 1990s and you have never had switchboard work done, it is worth having someone look before the notice arrives rather than during a four day window with the power off and an installer waiting.

If you are in Sydney and want that looked at, get in touch and we will put you onto a Level 2 electrician rather than guessing at it ourselves.

If someone at the property is on life support

This is the one part of install day with a hard legal edge, and it needs doing early. Where premises are registered for life support, supply cannot be interrupted without the customer agreeing the date and time first. That is a stronger protection than the ordinary notice rules, and it only works if the registration already exists.

Registration goes through your retailer or your distributor and involves paperwork and usually a medical confirmation, so it is not a same week job. If anyone at the property depends on powered medical equipment and you are not certain you are registered, start that now, independently of the meter rollout.

Before the day: a five minute checklist

1. Clear access to the meter box. Unlock gates, secure the dog, cut back anything growing over it. Access failure is the most common reason a visit is wasted.
2. Shut down anything with a hard drive. Computers, home servers, NVRs. An unclean power cut is how filesystems get damaged.
3. Plan for the fridge and freezer. Two hours is usually survivable if you keep the doors shut. If you have a second freezer full of food, that is worth thinking about rather than assuming.
4. Note the date and time. Write it down. You will want it later when you compare bills either side of the swap.
5. Check for a controlled load. If your hot water runs on a separate off peak circuit, note that too, so you can confirm afterwards that it still does.

On the day

The installer is contracted through your retailer. They will identify themselves and you are entitled to ask for photo identification. They will not ask you for payment, for bank details, or for personal information beyond confirming the address. Anyone doing so is not there to change your meter, and that is worth knowing because rollouts attract that kind of attention.

Your power goes off, the old meter comes out, the new one goes in, and power comes back. Some installers will knock; many will not if the box is outside and accessible.

Afterwards: two checks, and the second is the one people miss

1. Check everything came back on. Not just the lights: check the hot water, the oven clock, the air conditioner, and anything on a separate circuit. A controlled load that did not come back is easy to miss for weeks.
2. Compare the tariff name on your next bill against your previous one. This is the check that actually protects your money. If your meter was replaced on or after 1 December 2025, the retailer that installed it cannot move you off a flat rate onto time of use or demand for two years without your explicit informed consent, in NSW, Queensland, South Australia, Tasmania and the ACT, and only while you stay with that retailer.

After two years your retailer can change your tariff structure without consent, but must give at least 30 business days' notice and show what your last 12 months would have cost under the new structure. If your meter was swapped before 1 December 2025, or you have since switched retailers, that protection may not apply. There is a full walkthrough on what to do when the bill goes up after a smart meter.

Once the new meter is in, you have interval data for the first time, and it is the only record of what your house actually costs you hour by hour. We set up a home energy dashboard that puts that data against your tariff windows, tells you whether anything changed for the worse at the swap, and automates the shifting worth automating.
