If your home still runs on 100-amp service, a fuse box, or a panel that's tripping every time the microwave and hair dryer run together, you've probably wondered what a panel upgrade costs. Here's a straight answer for Chicago homeowners — no lowball bait, no scare tactics.
Typical cost of a panel upgrade in Chicago
- Standard 100A → 200A heavy-up: $2,500–$4,500
- Upgrade requiring a new mast, meter, or grounding: $3,500–$6,000
- 400A service for large or multi-unit homes: $6,000–$12,000+
These are typical installed ranges including permits and inspection. Your exact, flat-rate price is confirmed in writing before any work begins.
What drives the price
- Amperage — 200A is standard today; 400A costs more.
- Condition of the service entrance — a new mast, weatherhead, or meter base adds cost.
- Grounding & bonding — older homes often need updated grounding to meet code.
- Panel location & access — a finished basement or tight utility room takes longer.
- Permits & ComEd coordination — required, and we handle them.
Do you actually need an upgrade?
You likely do if any of these apply:
- You have 100A service, a fuse box, or a known-problem panel brand.
- You're adding an EV charger, kitchen remodel, addition, or hot tub.
- Breakers trip often, or you rely on power strips for everything.
- You're seeing scorching, buzzing, or warm panel covers (call right away).
If your panel is healthy and your loads are modest, we'll tell you that, too. The honest answer is sometimes "you don't need this yet."
Is it worth it?
A panel upgrade is one of the highest-value electrical investments in a home: it's the foundation for EV charging, modern kitchens, and safe capacity — and it's a common ask during inspections and resale. Done right and permitted, it's a once-in-a-generation upgrade.
