Short answer: Schedule every EV charger job as five gates, not one install day: site survey, permit, utility sign off, install and inspection. A job only gets a crew date once the gate before it is cleared. Keep one or two flex slots each week for the jobs that turn into panel or service upgrades, and promise the customer the inspection date, not the install date.
Why EV charger jobs slip
The work on site is short. A standard home Level 2 install is often four to six hours, and a clean job can go from signed quote to closed permit in one to three weeks (Towery Electric install timeline). The trouble is everything around that day.
When the panel cannot carry the extra load, the job becomes a service upgrade. Now you are waiting on the power company, and those windows can run anywhere from two to eight weeks depending on the market (BellaFSM EV charger scheduling guide). A job that looked like a Tuesday morning install is suddenly a five week project with a cutover window you do not control.
Demand keeps the pressure on. In the UK, TradeMatch tracked 18,400 jobs and found a median wait of six weeks for an EV charger installer, eleven weeks at the 90th percentile, and listed the trade as "tight" on capacity (TradeMatch UK wait time index 2026).
Step 1: Qualify the job before it touches the calendar
Most surprise upgrades are visible on the first call. Capture these before you book anything:
- Charger amperage the customer wants
- Main panel size, service rating and free breaker space
- Distance from panel to the parking spot
- Home, apartment block or commercial site
If the answers point to a load problem, tag it as a likely upgrade from day one.
Step 2: Track five gates for every job
| Gate | What has to be true | Who usually owns it |
|---|---|---|
| Surveyed | Load check done, scope agreed | Estimator or lead electrician |
| Permitted | Permit issued by the local authority | Office |
| Utility cleared | Utility has approved the added load or booked the cutover | Office, with the utility |
| Installed | Charger mounted, circuit run, tested | Crew |
| Inspected | Final inspection passed, permit closed | Office and crew |
A job moves on only when the gate before it is done. That one rule stops crews turning up while the permit is still in a queue.
Step 3: Book the crew only after the paperwork clears
On clean jobs, permits often come back within a few business days, so you can pencil in a crew date early. On upgrade jobs, keep the install as a tentative block and confirm it only when the utility gives you a cutover date. Some jobs need a rough inspection before you can energize and a final after the charger is set, so put both inspection visits on the plan the day you book the job.
Step 4: Hold a flex buffer every week
Even with a good intake call, some jobs reveal a weak panel on the day. Reserve one or two flex slots each week for those, the same way an outdoor crew holds a buffer for rain. Our post on weather delays in a construction schedule shows how to size that kind of buffer.
Step 5: Review the next three weeks every Friday
Look at every open job and ask one question: which gate is it stuck at, and who is chasing it? Move ready jobs into crew slots and push the rest back early. A 3-week lookahead is the simplest way to run this review without rebuilding the whole plan.
A quick example
A three person electrical shop has 14 open EV jobs. Ten are clean installs and four need service upgrades. The ten clean jobs go into crew slots as their permits clear, two a day. The four upgrade jobs sit as tentative blocks linked to their utility approval. When one utility date comes through, that job gets its crew day and the customer gets a firm inspection week.
Where Zace fits
Zace is a project and task tracker for installation crews and the office work around them. You can set up each EV job with the five gates as milestones, link the install task to the permit and utility tasks it depends on, and assign each step to a named person with a priority. The Gantt chart shows every job side by side, so a slipped utility date is visible the moment it moves. It runs on web, Android and iOS, so the crew on site and the person chasing permits work from the same plan.
Frequently asked questions
How long does an EV charger installation take from quote to finish?
A clean home install with no panel work often takes one to three weeks from signed quote to closed permit. Jobs that need a service upgrade can take several weeks longer because of the utility wait.
When should I give the customer a firm date?
Once the permit is issued and, for upgrade jobs, the utility has confirmed the cutover. Before that, share the next milestone and when you expect it.
