For a commercial or shared site, find installers the same way you would for a home — licence verified with the issuing authority, EV work evidenced — but judge the evidence at commercial scale: comparable sites completed, whole-site design capability, and permit and utility coordination handled as part of the job. A workplace, car park or apartment building has neither one decision-maker nor one charger, and the installer’s paperwork must match the bigger job.
Key Takeaways
- Verify the licence with the issuing authority, then judge commercial evidence: comparable sites, whole-site design, coordination.
- Source candidates from utility programmes, manufacturer channels and operators of comparable sites — and verify every referral.
- Same written scope, site visit before pricing, itemised quotes compared line by line.
- Match the installer’s commissioning experience to the actual hardware: networked stations are not mounted-and-done.
Where Commercial Candidates Come From
- Your utility’s commercial programmes. Utilities run EV infrastructure programmes for sites, not just homes, and the installers active in them do this work repeatedly; the U.S. DOE’s guidance on procurement and installation for EV charging infrastructure is the neutral map of how these projects are structured.
- The charger manufacturer’s B2B channel. Makers hear which installers fit their equipment well in each region. Ask for names — then verify them like any other candidate, because a referral is a lead, not a credential.
- Operators of comparable sites nearby. The facilities manager of a similar car park or workplace can name who fitted theirs and whether they would be hired again.
- Your managing agent or facilities peers. For apartment and mixed-use buildings, the agent running comparable properties usually holds a working shortlist already.
The Evidence That Separates Qualified From Willing
| Evidence | What to ask for | Why it decides |
|---|---|---|
| Licence for commercial electrical work | The licence number, verified with the issuing authority before any pricing discussion | It is the legal floor for the work; an unverifiable licence ends the conversation |
| Comparable completed sites | Named sites of similar size and type that you may call or visit | Multi-bay design and commissioning are learned on sites, not on single home chargers |
| Whole-site design capability | Who produces the load assessment and layout for the whole site — in-house, or a named design partner | A row of chargers is one electrical system; somebody qualified must own the arithmetic |
| Permits and utility coordination | Each step named in the quote as a field: permit filing, inspection, utility application, and who owns each | On commercial jobs these steps, not the mounting, are where schedules are won and lost |
| Aftercare terms | Fault response and warranty-callback terms in writing, as fields in the contract | A public or shared charger that is down is a visible failure; the response terms are part of what you are buying |
Run the Shortlist Like a Buyer
Give every candidate the same written job description — site plan, bay count, who charges and for how long, the hardware shortlist — and require a site visit before any price. Quotes against the same scope compare line by line; phone-call quotes cannot. Red flags are the commercial versions of the home ones: a price without a site visit, no licence number on the paperwork, permit or utility steps quietly pushed onto you, and design left to “sort out during installation”. Our guide to choosing an EV charger installation company covers the company route in more depth, and the breakdown of commercial installation costs shows which lines a serious quote separates.
The Hardware Shapes the Evidence You Need
What the installer will fit decides which experience matters. A networked station such as the EV-AC03201T (floor-standing, two Type 2 connectors sharing up to 43 kW, OCPP 1.6J, RFID, IP54) needs commissioning experience with connected, access-controlled hardware — ask who configures the station, not just who mounts it. A row of EV-ACT3204PE 22 kW wallboxes (tethered Type 2 cable, RFID and app, IP66) across a car park needs the multi-bay load design above. Match installers to the equipment shortlist on our commercial charging page before scoring them.
Frequently Asked Questions
Can our usual maintenance electrician do the job?
Possibly — the licence may cover the electrical work. The gap to test is EV-specific: whole-site load design, networked-charger commissioning, permit and utility paperwork. Judge that evidence, not the familiar name.
Should the installer also supply the chargers?
Either model works. Supply-and-fit puts one name behind the whole job, which simplifies fault calls; supplying the hardware yourself keeps the equipment contract in your hands. Decide before tendering, because it changes what each quote must cover.
How many quotes should a site get?
Two or three, each after a site visit and against the same written scope. The spread between commercial quotes is mostly scope differences in disguise — the line-by-line comparison is where the value sits.
