Safety inspections and service plans: steady work for electrical contractors

Generator maintenance, commercial inspections and smoke detector checks come back every year. Here's how electricians build repeat revenue.

Emergency calls pay the bills, but they're unpredictable. The electrical companies that grow steadily have something else: a base of customers who need them on a schedule.

Work that comes back every year

  • Standby generator maintenance and load testing.
  • Commercial emergency lighting and exit sign inspections.
  • Smoke and CO detector checks for landlords and property managers.
  • Infrared scans of commercial panels.
  • EV charger checkups for fleet customers.

Record what you install

Every generator, panel and charger you install is a future service call. Write down the brand, model, serial number and install date, and set a reminder for its next service.

Property managers love electricians who remind them before the inspection is due. It makes their job easier, and they'll send you every building they manage.

Start with your installs

Offer a yearly maintenance visit to every customer you install a generator for. In a year, you'll have a list of customers who already expect your call.
