How to choose an EV charger installer in Missouri
Hire a licensed electrician (NEC 625)
A Level 2 charger is a 240V branch circuit, so the work must be done by an electrician licensed in Missouri and follow NEC Article 625, which governs electric-vehicle supply equipment. Confirm they carry liability insurance and a labor warranty on the install, not just the manufacturer's warranty on the charger itself.
Check your panel can handle the new 240V circuit
A good installer runs a load calculation before quoting. A Level 2 charger typically needs a dedicated 40–60A double-pole breaker, and an older or fully-loaded panel may need a subpanel or a service upgrade. Ask whether your panel has the spare capacity or whether the quote includes panel work: it's the single biggest cost variable.
Confirm the permit, inspection & hardwired vs. plug-in
A reputable contractor pulls the electrical permit and schedules the Missouri inspection: skipping it can void insurance and fail at resale. Decide between a hardwired charger (cleaner, supports higher amperage, often required outdoors) and a NEMA 14-50 outlet (plug-in, portable). Both are valid; make sure the quote states which you're getting.
What to know before hiring in Missouri
The largest utilities serving Missouri homes are Union Electric (1,095,619 residential customers, 12.6¢/kWh), Evergy Missouri West (305,583 residential customers, 12.6¢/kWh) and Evergy Metro (273,860 residential customers, 13.7¢/kWh). Your utility sets the rate your charging costs, and it is also who an installer files interconnection or service paperwork with, so name it when you ask for quotes.
Check the license before you sign
Missouri licenses electrical contractors at the city or county level rather than statewide; the Missouri Division of Professional Registration, Office of Statewide Electrical Contractors is the starting point. Cities and counties license electricians; the optional Statewide Electrical Contractor license must be honored everywhere in the state.

The charger side of the install
Most electricians will install a charger you supply, and the circuit follows the charger: a 48 A hardwired unit needs a 60 A circuit, a 40 A plug-in unit a 14-50 on a 50 A circuit. Choose it before the quote so the quote matches. Most non-Tesla EVs built before 2025 have a J1772 port; a NACS car takes the wall charger's NACS version. The portable unit plugs into an existing 14-50 outlet on a 50 A circuit with no install. It is J1772-only.
