Switching internet providers as a business sounds riskier than it actually is. The NBN transfer process is well-defined, the steps are manageable, and when it's handled correctly, most businesses experience little to no downtime during the changeover. The concerns that keep businesses stuck with a poor provider — disruption, complexity, losing their connection — are almost always overstated. Here's the full picture of what the process actually involves.
Step 1 — Check your current contract
Before anything else, locate your current provider agreement and check two things: whether you're within a fixed-term contract period, and what the cancellation notice requirements are.
Most business NBN contracts are either month-to-month or on 12-month terms. If you're mid-contract, calculate the break fee (if any) and weigh it against what you'd save with a better plan. Many businesses are surprised to discover their current contract is already month-to-month — meaning there's no financial penalty to switching at all.
Also check whether your provider requires written notice before cancellation, and how many days in advance. Some providers require 30 days' written notice. If you're planning to switch, initiating that notice early avoids your service continuing to be billed after the transfer completes.
Step 2 — Check your connection type and upgrade eligibility
While you're reviewing your current setup, it's worth confirming what type of NBN connection your premises has — FTTP, HFC, FTTN, or FTTC. If you're on FTTN or FTTC, you may be eligible for a free upgrade to FTTP (full fibre to the premises). Switching providers is actually the ideal time to also upgrade your connection technology, because both can be coordinated as part of the same process.
A free FTTP upgrade combined with a move to a better Business NBN plan is one of the most cost-effective improvements an Adelaide business can make to its connectivity. Our FTTP upgrade page explains the process in detail — and we can check your address eligibility before you commit to anything.
Step 3 — Handle your static IP address if you have one
If your business currently uses a static IP address — for remote desktop access, VPN connections, hosted services, or IP-based security camera systems — this needs careful planning before the transfer date.
Your static IP is assigned by your current provider, and it will be released when your service transfers. You'll receive a new static IP from Caznet as part of the onboarding process, but before the switchover date you need to update any services, firewall rules, or DNS records that reference your old IP address. Failing to do this before the transfer means those systems will lose their connections.
If you're not sure whether your current setup uses a static IP, your provider can confirm this. Caznet includes static IP allocation as an add-on to any Business NBN service.
Step 4 — The transfer process
One of the most common misconceptions about switching NBN providers is that you need to contact your current provider to initiate a cancellation. You don't. The new provider submits an NBN transfer request on your behalf through NBN Co's systems, and your current provider is notified automatically as part of that process.
Once the transfer request is submitted, a transfer date is scheduled. Caznet keeps you informed throughout — you'll know the date and the expected service window well in advance, giving you time to plan accordingly. The process is entirely managed on your behalf.
Step 5 — The switchover window
Most NBN provider transfers involve a brief service interruption during a scheduled window — typically under 30 minutes. The exact duration depends on the connection type and the specific transfer circumstances, but for most business premises it's a short, predictable window rather than an extended outage.
Choose a time that minimises impact. For most Adelaide businesses, early morning before staff arrive, or late afternoon as the day winds down, works well. If you have a 4G hotspot or a mobile plan with data sharing, having that available as a temporary backup during the window is straightforward insurance — your team can keep working via mobile data for the 20–30 minutes the transfer takes.
Once the transfer is complete, your new service activates and the old service is automatically discontinued. There's nothing further to do with the outgoing provider beyond any notice period or final billing matters.
What doesn't change when you switch
Your physical NBN connection infrastructure stays exactly the same. The same cables, the same connection device on the wall — none of that changes when you switch providers. Your NBN connection type (FTTP, HFC, FTTN, etc.) remains as-is unless you've specifically arranged an upgrade as part of the process.
Your business phone numbers are also entirely separate from your internet service. Switching internet providers has no effect on any phone numbers your business uses, whether they're on a VoIP system or a separate phone service. The two services operate independently.
