Electricians in Cambridge, Massachusetts

Cambridge is in Eversource electric territory, so homeowners are Mass Save eligible. The electrical work isn't rebated on its own, but a 200A panel upgrade is generally the prerequisite for a Mass Save heat pump or heat-pump water heater — older Cambridge homes on 100A or fuse service usually can't carry the added load.

Cambridge's own climate-action goals lean hard toward electrification, so pairing the service upgrade with the Eversource/Mass Save rebate path is common. In pre-1940 homes, knob-and-tube remediation also matters for insurability, since carriers in this market frequently flag active old wiring.

Electrical work in Cambridge requires a permit under 527 CMR 12.00, the Massachusetts NEC amendments, and a licensed Journeyman or Master electrician. Permits are pulled through the Cambridge Inspectional Services Department, and a municipal wiring inspector signs off before energizing. Panel upgrades, EV circuits, meter relocations, and rewires all need permits. Cambridge has historic districts (including Old Cambridge and Avon Hill) where exterior-visible changes such as meter or service-mast relocations can trigger Historical Commission review, so flag that early.

Cambridge sits at the high end of the state on labor and access, similar to Boston. A 100A-to-200A panel upgrade typically runs $3,000–$5,500; meter relocations and mast work push higher. A Level 2 EV-charger circuit generally runs $1,200–$2,500 depending on the run to off-street parking, which is scarce here. Knob-and-tube rewiring is priced by accessibility and often lands $8,000–$20,000 for a full home. A whole-home generator with transfer switch usually runs $9,000–$16,000 installed.

Cambridge packs about 53,900 housing units into Middlesex County, with a median home age around 80 years. The mix runs from triple-deckers and worker cottages in The Port and Cambridgeport to large Victorians near Harvard and Porter Squares — much of it predating modern electrical service and still wired with knob-and-tube behind plaster.

That density and age make panel upgrades and partial rewires the most common jobs. Lot lines are tight, so EV-charger runs and meter relocations take planning, and the city's strong push toward building electrification keeps service-upgrade demand high among owners preparing for heat pumps.
