What Should Be on a Switchboard Upgrade Quote?
Contents
A switchboard quote can look tidy, itemised, even professional, and still leave you wearing a few thousand dollars in extras once the sparky starts pulling covers off.
That happens a lot with EV charger jobs. Someone gets a price for the charger, gets a separate price for a switchboard upgrade, thinks they’re covered, then the real job starts. No spare ways. No RCD protection where it needs to be. Meter panel too small. Consumer mains not up to it. Network paperwork not included. Suddenly the “quote” was really just a starting point.
If you’re comparing a switchboard upgrade quote in Melbourne, especially for an EV install, this is what should be spelled out before anyone books the work.
The quote should describe the board you have now, not just the board you’ll get
A proper switchboard upgrade quote starts with the existing condition, not a vague promise to “upgrade switchboard”.
If the quote doesn’t say what was actually inspected, it’s weak. At minimum, it should note things like:
- ceramic fuses, plug-in breakers, or an older mixed board
- whether there are existing safety switches and which circuits they protect
- number of spare poles or ways available
- condition of the enclosure and meter panel
- signs of heat damage, brittle cabling, overcrowding, or non-compliant labelling
- whether the board appears capable of supporting an EV charger circuit
That matters because two homes in Northcote with the same looking front box can be completely different once opened. One might need a straightforward breaker and RCD reconfiguration. The other might need a full enclosure replacement and meter panel rebuild.

What a complete quote should actually include
This is the homeowner quote checklist most people wish they had before signing.
A decent electrical upgrade quote should list the actual scope, not just a lump sum. Look for these inclusions:
| Quote item | What it should say |
|---|---|
| Inspection findings | Existing board type, defects noted, available space, current protection status |
| New enclosure or reuse | Whether the existing enclosure stays, gets replaced, or is subject to inspection once opened |
| Main switch and breakers | Ratings, number of circuits, whether new RCBOs/RCDs are included |
| Safety switch coverage | Which final subcircuits will be RCD protected after the job |
| Neutral and earth bars | Whether upgrades or additions are included |
| Meter panel work | Whether the meter panel is being modified, replaced, or excluded |
| Labelling | Circuit identification and mandatory labels |
| Testing and verification | Insulation resistance, polarity, earth continuity, RCD trip testing, fault loop where applicable |
| Compliance paperwork | Certificate of Electrical Safety in Victoria, and whether inspection is included if required |
| Making good | What happens to holes, patching, mounting, tidy-up |
| EV charger interface | Dedicated circuit, breaker sizing, RCD/RCBO type, load management interface if needed |
| Exclusions and assumptions | Clear list, not buried in fine print |
A quote that just says “switchboard upgrade including safety switches” is not a real scope. It’s a placeholder.
The items that get left out of a switchboard quote for EV charger jobs
The most expensive surprises are usually not the charger itself. They’re the bits around the board that nobody priced properly.
With a switchboard quote for EV charger work, the common omissions are:
- Load calculation or maximum demand assessment
This is the big one. If the quote doesn’t mention load assessment, the electrician may only be pricing a hardware swap, not checking whether the home can legally and safely add a 7 kW or 11 kW charger.
- Dedicated EV circuit protection
The quote should specify breaker size, cable assumptions, and the type of RCD/RCBO arrangement required for the charger being installed.
- Space constraints in the board
If the board is full, the quote should say whether it includes extra enclosure space, a new DIN enclosure, or a complete board replacement.
- Meter panel changes
Older timber meter panels and cramped meter arrangements often need alteration to fit compliant gear neatly and safely.
- Consumer mains upgrade
If the existing mains are undersized for the proposed load, that can turn into a bigger job fast.
- Network coordination
Temporary isolation, reconnection, or distributor involvement may be separate.
- Load management hardware
If the property can’t support full charger output all the time, the quote may need dynamic load management or charger throttling hardware.
A lot of homeowners search for a switchboard quote for EV charger installation and assume the quote covers “whatever’s needed”. It often doesn’t. It covers only what the sparky was confident enough to price from a visual check.
“Subject to inspection” is fair. “We’ll sort it on the day” is not.
Unknowns are normal in switchboard work. Lazy quoting is not.
No electrician can promise every detail before opening an old board. That’s real life. Covers come off and you find doubled-up neutrals, damaged insulation, asbestos backing nearby, or a meter panel that’s had three decades of add-ons.
What matters is how those unknowns are handled in the quote.
A good quote will do one of these two things:
- Price a defined scope with stated assumptions
Example: price includes replacement of existing domestic switchboard enclosure up to X modules, replacement of main switch, installation of RCBO protection to nominated circuits, testing, labelling, and certification. Excludes consumer mains upgrade if existing mains are found undersized.
- Split fixed items from provisional items
Example: fixed price for standard board upgrade, provisional allowance for meter panel rectification or additional circuit separation if required after inspection.
That’s reasonable. What you don’t want is a cheap headline figure with half the job left floating.
Before pricing is locked in, insist the electrician checks:
- the board with cover removed, if safe and practical
- available pole space
- main switch rating
- whether there are existing RCDs and what they protect
- cable entry space and enclosure condition
- likely EV charger size and charging method
- whether the home has major electric loads like induction cooking, ducted air con, heat pump hot water, or pool equipment
If the board hasn’t been properly inspected, the quote is a guess with better formatting.
The quotes that look complete, but still leave you exposed
Some quotes look detailed because they list parts. That doesn’t mean they cover the job.
These are the traps that catch people:
“New switchboard with safety switches”
That sounds complete. It isn’t. It doesn’t tell you:
- whether all required circuits will be RCD protected
- whether old breakers are being reused
- whether the enclosure is new or existing
- whether the meter panel is included
- whether testing and certification are included
“Includes EV-ready switchboard”
That phrase means nothing unless the quote defines it. EV-ready could mean:
- one spare breaker space
- a dedicated circuit provision
- actual load capacity for a charger
- load management compatibility
Those are not the same thing.
“Excludes defects not visible at time of quote”
Fair enough in principle, but it can be abused. If the electrician never opened the board, nearly everything becomes a hidden defect later.
“Upgrade to current standards”
Current standards is too broad. A quote should say what compliance work is included, what is being left as existing, and whether the price is for a basic upgrade or a full rework of the affected board area.
If the board is tight for space, the quote needs to say exactly what happens next
Limited space is where switchboard jobs blow out.
A proper quote should state one of the following:
- existing enclosure has sufficient space for new protective devices and EV circuit
- existing enclosure is to be replaced with a larger enclosure
- meter panel requires modification or replacement
- adjacent equipment will be relocated
- additional sub-enclosure will be installed for EV protection devices
If none of that is mentioned, and your existing board is already packed, expect a variation.
Here’s what that usually looks like in older Melbourne homes, especially in suburbs like Preston and Northcote:
| Existing condition | What the quote should clarify |
|---|---|
| Full board, no spare ways | New enclosure size and module capacity |
| Old timber meter panel | Whether replacement or rectification is included |
| Mixed old and new devices | Whether all protective devices are being standardised |
| Surface-mounted gear added over time | Whether relocation and cable extension are included |
| No room for EV protection gear | Whether a separate enclosure will be installed |
This is also the point to ask about future-proofing. If you’re already replacing the board, adding a bit of extra capacity now is usually cheaper than reworking it again in two years.
For EV charger quotes, load calculation is not optional
If your switchboard quote for EV charger work does not mention load, maximum demand, or load management, slow down.
An EV charger is not just another GPO. A typical single-phase home charger at 32A is a serious continuous load. If the house already has reverse-cycle air con, an electric oven, induction cooktop, and heat pump hot water, the board and supply need to be assessed properly.
The wording you want to see is along the lines of:
- maximum demand assessment included
- load calculation to confirm charger size suitability
- charger output subject to site load capacity
- dynamic load management included or available if required
- quote is for switchboard hardware upgrade only and does not include supply capacity assessment
That last one is especially important. If the quote says, in effect, “basic switchboard upgrade only”, then it may not be a full compliance pathway for the EV charger. It may only be making room in the board.
That doesn’t make it wrong. It just means you need to know what you’re actually buying.
A proper switchboard quote for EV charger work should also say whether the charger is being set to:
- full rated output
- reduced output
- load-managed output
- future-ready only, with charger circuit provision but no charger installed yet
If you’re comparing a switchboard quote for EV charger jobs, compare the charging outcome, not just the switchboard price.
Key takeaway: The right quote does not just tell you what hardware is being changed, it tells you whether the home will legally and safely support the charger you actually want to use.
The separate costs homeowners don’t realise sit outside the switchboard price
Some of the most annoying costs are not in the board itself. They sit around the job.
These can include:
- temporary power disconnection and reconnection
- distributor or network provider coordination
- service fuse or service line work
- metering provider attendance, where relevant
- after-hours shutdown requirements
- defects that trigger supply-side work outside the electrician’s scope
In Victoria, whether this is needed depends on the setup and the extent of the work. Sometimes the electrician can isolate and complete the job as part of normal domestic work. Sometimes the supply arrangement means external coordination is needed.
Your quote should say clearly:
- whether temporary disconnection is included
- whether network or metering charges are excluded
- whether supply-side defects are outside scope
- whether any permits, inspections, or certificates are included
For that side of the job, this guide helps: What Permits, Inspections or Certificates Are Needed?
And yes, certification matters. In Victoria, switchboard work should end with the right paperwork, not just a new row of breakers and a handshake.
Future-proofing is cheap on paper, expensive later
If you’re touching the switchboard now, ask one blunt question: will I have to redo this board for solar, a battery, or a second EV?
A proper quote should clarify whether the upgrade allows for:
- spare capacity in the enclosure
- spare breaker ways
- busbar or DIN space for future devices
- compatibility with solar inverter connections
- battery isolator and protection space
- a second EV charger or load management expansion
This doesn’t mean paying for gear you don’t need yet. It means the quote should tell you whether the board being installed is a minimum-compliance board for today, or a sensible board for the next five to ten years.
That’s especially relevant in renovations and investment properties. Landlords often install one charger provision now, then get stung later when a tenant wants a second EV bay or the owner adds solar. The original quote looked cheap because it was built to the absolute minimum.

A practical checklist before you accept any quote
If you only do one thing, send this checklist back to the electrician and ask them to confirm each point in writing.
- What exactly was inspected before quoting?
- Is the quote based on the existing enclosure being reused or replaced?
- Are RCBOs/RCDs included, and which circuits will be protected?
- Is testing, labelling, and certification included?
- Does the quote include maximum demand or load assessment for the EV charger?
- If the board is full, what enclosure or meter panel changes are included?
- Are consumer mains excluded, included, or subject to inspection?
- Are temporary disconnection, network coordination, or metering charges included?
- Is the quote for a full EV-ready compliant setup, or only a basic switchboard hardware upgrade?
- How much spare capacity will remain for solar, battery, or another charger?
If the answers come back vague, the quote is vague.
What switchboard upgrade cost should tell you, and what it won’t
Price matters, but the spread in switchboard upgrade cost usually comes from scope, not greed.
A cheaper quote may exclude:
- enclosure replacement
- meter panel works
- full RCD coverage
- load calculations
- certification or inspection coordination
- future capacity
- rectification of defects found once opened
A higher quote may genuinely include all of that. Or it may just be high. The only way to know is to compare line by line.
This is why fixed quotes matter. If a sparky offers upfront pricing, no call-out fee, and is clear about assumptions and exclusions before starting, you’re in a much safer spot than with a bargain number scribbled over text. Good switchboard work should also come with the basics you’d expect, licensed and insured, local, and willing to make it right if the work’s not right.
If your board also needs modern Safety Switches & RCDs as part of the upgrade, that should be called out plainly in the scope, not treated like an optional extra discovered halfway through.
The next step
Pull out the quote you’ve got, or the two you’re comparing, and mark it up against the 10-point checklist above. If the quote doesn’t mention load assessment, enclosure space, testing, certification, exclusions, and network-related costs, send it back and ask for those points to be confirmed in writing before you approve anything.
If you want a sparky to sort the whole thing properly, Pender Electrical handles Switchboard Upgrades and EV charger related board assessments with fixed quotes before work starts, no call-out fee, and clear scope so you’re not guessing what’s included. If you’re in Melbourne, book a quote and get it priced properly before the charger install turns into a variation fight.
