The EV Charger Quote That Takes Three Site Visits and Still Loses

The Real Problem

Dave is a registered electrician in South Auckland. Three years ago, he was doing mostly new-build rough-ins and commercial maintenance. Today, more than a third of his enquiries are EV charger installs, and he is losing money on most of them.

Not because the jobs are bad. The jobs are fine. The problem is that every EV charger quote involves a free site visit, and every site visit is different.

A typical week looks like this:

• Monday morning: text from a homeowner in Papakura. "Just got the Tesla. Can you install a wall charger?" Dave drives 45 minutes, looks at the switchboard (1998, needs an upgrade), measures the cable run from the garage to the board (22 metres, through a ceiling cavity), checks the main fuse (60A, probably fine), and quotes $2,800.
• Tuesday: homeowner says "I got another quote for $1,600, no switchboard work needed." Dave tries to explain that the other electrician didn't see the sub-board situation, but the customer has already decided. Lost job. Lost two hours.
• Wednesday: text from Manurewa. "How much for an EV charger?" Dave replies "depends on your place, happy to come have a look." No response.
• Thursday: drives to Flat Bush. Homeowner wanted "a quick quote." The garage is detached. Fifteen metres of trenching required. Customer does not want to hear this. Another no.

By Friday, Dave has done four site visits, quoted three jobs, won one. Two evenings gone, $180 in fuel, and a job worth $1,800. His actual hourly rate for the week on EV work is about $28.

The hidden cost is that every "quick quote" request from an EV owner sounds simple to the customer. They have seen a price online — "$1,200 installed" — and they want that price. They do not know their switchboard is from 1998. They do not know their main fuse is 60A. They do not know that the cable run through their attic is 25 metres, not 5.

Every site visit is Dave trying to explain why the $1,200 figure does not apply to their specific house, while they look at him like he is trying to upsell them.

Why Existing Tools Don't Solve This

Fergus and simPRO handle the scheduling and invoicing once the job is booked. They do not help qualify the enquiry.

A generic missed-call auto-text — "Thanks for calling, we'll get back to you!" — does not tell the customer what information Dave actually needs to quote. The customer thinks it is a simple question. Dave knows it is not.

A website quote form with "what kind of EV do you have?" captures the wrong variable. The make of the car does not determine the install cost. The switchboard does. The cable run does. The main fuse does. The existence of a sub-board in the garage does.

Even the bigger tools — Trademe Jobs, Builderscrack, NoCowboys — just pass the lead through. The homeowner types two lines, five electricians get notified, everyone has to do a site visit to quote, and whoever quotes lowest (usually by ignoring complications) wins. Until the complications surface mid-install.

How AI Solves This

Your OpenClaw AI assistant runs the front-end conversation — on your website, WhatsApp, or Facebook — and asks the same questions a seasoned electrician would ask on the phone, but in a way that feels natural to the homeowner.

The Conversation

Customer (Saturday 7:42pm): "Kia ora, I need an EV charger installed. Just picked up a BYD Atto 3. How much?"

AI: "Congrats on the new EV. Installation cost depends on a few things about your house. Quick questions so I can give you a realistic range:

1. Roughly how old is your home? (e.g., new build, 2000s, 1980s, pre-1970s)
2. Where do you want the charger? (attached garage, detached garage, carport, driveway)
3. Roughly how far is that from your main switchboard? (same wall, next room, across the house, outside to shed)
4. Do you know if you have a modern switchboard with RCBOs, or an older one with ceramic fuses?
5. Your address suburb? (so I can check we service the area)"

Customer: "Papakura. It's a 1980s brick and tile. Attached garage. The switchboard is in the laundry, maybe 15 metres from where I'd want the charger. Switchboard has black plastic things, not ceramic, but it looks old."

AI: "Thanks — that's really useful.

Based on what you've described, this is most likely a standard single-phase install with a short cable run through the ceiling cavity. The switchboard sounds like an MCB board from the 90s, which is usually fine for adding a 32A EV charger circuit, but your main fuse capacity matters.

A typical install for this setup: $1,600–$2,200 supply and install for a 7.4kW wall charger (Myenergi Zappi, Wallbox Pulsar, or similar), assuming:

• Main fuse is 63A or higher (most 1980s homes are 60A, which may need an upgrade — $400–$800 extra)
• No additional trenching required
• Council notification (COC) included

I can't give you an exact number without Dave checking two things on site:

1. Main fuse rating and meter box condition
2. Cable run path (there can be asbestos in 80s ceilings — we never drill without checking)

Want me to book a 30-minute site visit? Dave has Tuesday 4pm or Saturday 9am open this week."

Customer: "Saturday 9am works. What do you charge for the site visit?"

AI: "Site visit is free — Dave will give you a firm quote on the spot, in writing. If you book the install, no charge. If you decide not to proceed, still no charge. You'll get a confirmation text shortly."

What Just Happened

Before Dave has seen this message, the AI has:

• Captured the suburb (is it in the service area — yes, Papakura is fine)
• Flagged the likely main fuse upgrade ($400–$800) so the homeowner is not shocked by it later
• Quoted a realistic range ($1,600–$2,200 baseline) rather than a headline $1,200 that will require an awkward conversation on site
• Booked a 30-minute visit, not an hour — because half the questions have been answered already
• Documented the ceiling cavity asbestos risk (real issue in 80s/90s NZ homes) so Dave knows to bring the right gear

When Dave opens his laptop on Sunday morning, there is one line in his inbox: "EV charger install booked. Papakura. 1980s brick/tile. 15m cable run attached garage. MCB board (likely 60A main fuse — quote upgrade). Site visit Saturday 9am."

That is a qualified lead. Dave arrives on Saturday already knowing what he is quoting. The site visit confirms, it does not discover.

What the AI Knows

The AI pulls from your knowledge base:

EV-CHARGERS.md:

## Charger Types We Install
- 7kW single-phase (most common residential): $1,200–$1,700 supply
- 11kW three-phase (some newer homes / commercial): $1,800–$2,400 supply
- 22kW three-phase (commercial / fleet): $2,800+ supply

## Install Cost Drivers
- Cable run < 10m through accessible cavity: baseline
- Cable run 10–25m or through walls: +$200–$500
- Cable run > 25m or needing trenching: +$600–$1,500
- Main fuse upgrade (60A → 80A or 100A): +$400–$800
- Switchboard replacement (pre-1990 / ceramic fuses / no spare space): +$1,500–$3,000
- Asbestos ceiling — need licensed removal or bypass route

## We Do Not Quote Over Phone/Text
We give a realistic range based on the above info. Final quote is always from site visit.

COMPLIANCE.md:

## Certification
- Every EV charger install requires Certificate of Compliance (CoC) — we handle this
- Electrical Safety Certificate (ESC) issued by Dave
- Notifiable work registered with the council (included)
- Never install without a CoC — homeowner cannot insure the install

The AI never promises a specific price. It never says "it'll be $1,200." It gives ranges and flags the variables that matter.

How We Set This Up

The reason this works is not just the chatbot. It is the integration we build to connect the chatbot to the rest of your business.

Here is what BestAI does for an electrician signing up for OpenClaw:

1. We capture your quoting logic. We sit with you and write down how you actually quote EV charger jobs. Not the fluffy version on your website — the real version, the one in your head. What do you ask? What tips you off? What adds cost? What are the red flags? That becomes the knowledge base.
2. We build the calendar connection. Your Google Calendar, Fergus, simPRO, or just a Trello board — we write a custom program (API connector) that lets the AI book site visits directly into your existing system. You do not have two calendars. You do not enter anything twice.
3. We set up lead notifications the way you want them. Email summary? SMS at 7am each day? Push notification? You tell us how you want to be told about new jobs, and we configure it.
4. We integrate with your quoting tool. If you use a tool like Tradify or Fergus to send quotes, we can have the AI pre-fill a draft quote with the gathered info, ready for you to review and send.
5. We keep it current. EV charger pricing changes. New models come out. New brands appear. We update the AI's knowledge base monthly so it never quotes a discontinued product or a last-year price.

You do not need to be technical. You do not need to know what an API is. That is what we are paid for. You run your electrical business. We run the software.

The Result

• Fewer wasted site visits. Homeowners who do not want to pay for a switchboard upgrade self-select out of the conversation before you drive 45 minutes.
• Accurate expectations on arrival. The customer already knows a 1980s home with a 60A fuse will cost more than a new build. No awkward conversation on site.
• Shorter site visits. 30 minutes instead of 60, because the AI already captured cable run, switchboard type, and charger preference.
• Evening enquiries captured. Tesla deliveries happen on weekends. BYD deliveries are often Saturday mornings. The AI responds in 60 seconds, 24/7.
• Higher quote win rate. The first electrician who gives a realistic, detailed response wins the job — even if their final number is higher — because the homeowner trusts them more.

What AI Can't Do Here

• AI will not size a main fuse upgrade — that requires looking at the meter.
• AI will not issue a CoC or ESC — that is your licence and your responsibility.
• AI will not recommend a charger brand for a specific EV without checking compatibility — we train it to recommend ranges, not specific products for specific cars.
• AI will not negotiate price over chat — that is your call, not its.

Who This Is For

• Registered electricians installing EV chargers in Auckland, Wellington, Christchurch, and regional NZ
• Solo sparkies and 2–5 person teams who are losing evenings replying to "how much for an EV charger" texts
• Any electrician tired of driving to Papakura for a free site visit that turns into a $0 job because the homeowner got a cheaper quote from someone who did not factor in the switchboard
• Electricians who want to compete on quality and accuracy, not the race to the lowest headline number
