Queensland-wide commercial switchboard project delivery
- info@commercialswitchboards.com.au
Commercial switchboard upgrade cost is driven by the board size and supply, any metering or Energex changes, site access and shutdown windows, and the condition of the existing installation, rather than one fixed price. The largest hidden cost is usually the unplanned outage when an ageing board finally fails. A site review gives an accurate figure, and this guide explains exactly what moves the number.
Every facility manager wants the same thing before approving a switchboard project: a clear idea of what it will cost and why. The honest answer is that commercial switchboard upgrade cost varies from site to site, because a board is engineered for the load, the supply and the building, not bought off a shelf. What does not vary are the factors that move the price. Understand those and you can budget accurately and compare contractors on a like-for-like basis.
Five things move the figure more than anything else.
| Cost driver | Why it matters |
|---|---|
| Board size and amperage | More current and more circuits mean more switchgear and busbar |
| Supply and metering changes | CT metering and Energex coordination add scope |
| Access and shutdown windows | After-hours or staged shutdowns on a live site add time |
| Site condition | Old cabling, asbestos backing or non-compliant work adds remediation |
| Documentation and compliance | Type-test evidence and as-built drawings to AS/NZS 61439 |
When comparing pricing, make sure each one covers the same scope:
The only way to price a switchboard upgrade properly is a site review. A specialist inspects the existing board, assesses the load and supply, checks for asbestos and non-compliant work, and confirms what Energex coordination is needed. From there you get a clear, fixed figure with no surprises mid-project.
Because switchboards are all we do, we price the full job up front, including the supply and compliance work a general electrician can miss. That means fewer variations once the project starts, and a board built right the first time.
Why can’t you give a fixed price online?
A switchboard is engineered for the site’s load and supply, so an accurate figure needs a site review. We provide a clear fixed figure after that, not a vague range.
What is the most expensive part of a switchboard upgrade?
Usually the board size and any supply or metering changes that involve Energex. Site remediation, such as asbestos or old cabling, can also add scope.
Is it cheaper to repair than upgrade?
For a localised fault on a sound board, yes. For an overloaded, non-compliant or repeatedly failing board, an upgrade is the better value over time.
Does an upgrade always involve Energex?
Where the supply or metering changes, usually yes. The coordination is handled for you as part of the project.
How do I compare contractors fairly?
Make sure each figure covers the same scope: design, AS/NZS 61439 manufacture, staged install, Energex coordination and full documentation.
How long is a pricing figure valid?
This varies with material prices, which is confirmed at the time of the site review.
