For most of the trade’s history, electrical work hasn’t had much of a cybersecurity angle. Wire, panels, breakers — physical infrastructure that doesn’t care about phishing emails. That’s changed, and it’s changed specifically because of where electrical work is growing fastest: EV charger installation.
A Level 2 home charger or a commercial charging bank isn’t just a bigger breaker and an outlet anymore. It’s a network-connected device that talks to a billing system, sometimes a utility, and often a mobile app — and cybersecurity researchers have spent the last two years actively finding real, documented vulnerabilities in exactly how that communication works, published everywhere from industry security research to peer-reviewed conference papers.
This One Isn’t On You to Patch — But the Access Around It Is
To be direct about scope: the vulnerabilities researchers keep finding are almost always in charger firmware and network protocols — things the manufacturer and the charging network operator are responsible for fixing, not something an installing electrician can patch. That part isn’t your liability.
What is worth paying attention to is what installing and commissioning that equipment actually requires: getting the unit onto a client’s network, configuring it to talk to a billing or fleet-management platform, and often leaving remote access in place afterward for warranty support or troubleshooting. That’s real, sometimes persistent, access to a client’s network — the same category of vendor access that’s turned plenty of unrelated trades into an unexpected way into a client’s systems.
Why Commercial Clients Are Starting to Ask Questions They Didn’t Used To
Property developers, fleet operators, and commercial building owners installing charging infrastructure at scale have started treating that installation access the way any other vendor network access gets treated: something to vet before signing off on the work, not something to assume is fine because the electrician is licensed and insured for the electrical side of the job. Licensing was never a stand-in for network security, but it’s only recently become a question that gets asked out loud during EV and smart-building projects specifically.
The More Familiar Risk Is Still There Too
EV work is the newest wrinkle, not the only one. Panel upgrades, service calls, and commercial jobs still run on the same invoicing and progress-payment cycle every trade deals with — and a compromised inbox intercepting a payment request for a major equipment order is exactly as costly here as anywhere else. Scheduling matters differently for electrical work than for something like HVAC: the pressure usually isn’t a weather emergency, it’s a missed inspection window on a commercial project with a schedule and penalty clauses attached to it. A locked scheduling system doesn’t just cost a day of work — it can push back an entire project’s timeline.
What Actually Helps
None of this means turning an electrical contracting business into an IT shop. It means the basics are handled by someone whose job that actually is: email protection that catches the invoice-fraud attempt before it reaches the person who approves payments, monitoring for logins that don’t look like the employee who’s supposed to be using them — increasingly relevant as remote-access credentials for client installations pile up over time — and straightforward security awareness training so a convincing fake email doesn’t get the click.
