If your home has ceramic fuses, a board older than 25 years, or you're planning to add a heat pump or EV charger, you almost certainly need a switchboard upgrade. The fastest correct next step is to book a licensed inspection and request an itemised quote.
What to check before you call:
- Ceramic or rewirable fuses instead of circuit breakers
- Circuits that trip frequently under normal load
- Visible rust, corrosion, or a burning smell near the board
- No RCD (residual current device) protection on circuits
- Board age considered old and possibly needing replacement
Planning figure: On-site work typically takes several hours, with power disconnection during part of that time.
All switchboard work is notifiable electrical work in New Zealand. Only an EWRB-registered electrician can legally complete it and issue the required Certificate of Compliance (CoC). DIY is not a legal option.

When should you upgrade, and does it make sense to bundle?
Timing a switchboard upgrade alongside a kitchen or bathroom renovation, or before installing a heat pump or EV charger, reduces total cost and avoids a second site visit. Without adequate board capacity, electricians cannot add high-load circuits, and renovation projects stall. Doing the upgrade first removes that bottleneck.
Older boards often need full replacement rather than a simple upgrade, because modern RCDs may not fit the old enclosure. At that point, full replacement is the better investment. If you're already coordinating trades for a renovation project, adding the switchboard to the same scope is straightforward.
What drives the cost of a switchboard replacement?
Standard residential upgrades in New Zealand typically range in the lower thousands of NZD, with complex jobs costing more. The main cost drivers are:
- Board size and circuit count: more circuits mean more breakers and RCDs
- Full replacement vs. upgrade: older boards usually require a new enclosure
- Surge protection: an optional but recommended addition
- Asbestos remediation: pre-1980s boards may contain asbestos, requiring professional removal before work starts
- Access and location: awkward board placement adds labour time
Always request an itemised quote that separates materials, labour, RCD protection, and inspection fees.
How does a compliant upgrade affect your insurance?
Many insurers require evidence of compliant electrical installations to maintain cover. A current CoC confirms your switchboard meets NZ electrical standards and is the document your insurer may ask for after a claim or at renewal. Keep it with your property paperwork. An outdated board can complicate both insurance claims and property sales.
How do you choose a licensed electrician in New Zealand?
Verify EWRB registration before signing anything. Ask for a fixed written quote, confirm the electrician will arrange the independent inspection, and check that a CoC will be issued on completion. Red flags include verbal-only quotes, no mention of a CoC, or any suggestion that the work does not need to be notified. For guidance on vetted Auckland electricians, check that they hold current EWRB registration and carry liability insurance.
What does the full project timeline look like?
- Initial assessment: electrician reviews board condition, capacity, and RCD status
- Itemised quote: fixed price covering materials, labour, and inspection
- Scheduling: network company notified; disconnection window confirmed
- On-site work: completed in one working day for most residential jobs; new enclosure, breakers, RCDs, surge protection, labelling, and safety testing
- Independent inspection and CoC: issued before the electrician leaves; handed to you with all documentation
From first contact to CoC handover, most straightforward jobs are completed within one to two weeks, depending on scheduling.
Financing and payment options for switchboard upgrades
Most licensed electricians offer standard invoice terms. Some contractors provide payment plans for larger jobs, particularly when the switchboard upgrade is part of a broader renovation scope. It is worth asking at the quote stage. If the upgrade is bundled with kitchen, bathroom, or other renovation work, a single managed contract can spread the cost across the full project. Check whether your bank offers a personal loan or home-improvement credit facility, as switchboard work is a permanent improvement to the property.
Sortedhomesolutions manages your switchboard upgrade end-to-end
Coordinating a switchboard upgrade means managing an EWRB-registered electrician, network company disconnection, an independent inspection, and CoC handover. Sortedhomesolutions handles all of that under one contract, with a single point of contact from assessment through to documentation.
The process is straightforward: Sortedhomesolutions conducts an initial load review and assessment, provides a fixed itemised quote, coordinates the network disconnection window, and schedules a licensed electrician to complete the work. If asbestos remediation or additional trades are needed, those are managed within the same project scope. You receive the CoC and all handover paperwork on the day the job is completed. Bundling the upgrade with a kitchen, bathroom, or other renovation is handled within the same managed contract, which is where the real cost saving comes in.

Key takeaways
A switchboard upgrade in New Zealand requires an EWRB-registered electrician, produces a Certificate of Compliance, and is best timed alongside major renovations or high-load appliance installs to reduce cost and disruption.
| Point | Details |

| Legal requirement | All switchboard work is notifiable; only an EWRB-registered electrician can complete and certify it. |
| On-site timing | Several hours on site; power is typically disconnected during part of that time. |
| Typical cost range | Standard residential upgrades run $1,500–$3,000 NZD; complex jobs reach $3,000–$5,000. |
| Bundle for savings | Aligning the upgrade with renovations or heat pump/EV charger installs reduces site visits and total cost. |
