Electrical panel upgrade (100A to 200A): cost & ROI
Upgrading the home's electrical panel from 100-amp to 200-amp service — increasingly necessary for modern loads like EV chargers, heat pumps, and induction cooktops. It rarely adds visible value, but an outdated or undersized panel is a red flag for inspectors and a deal-breaker for buyers planning electrification.
Worth knowing: Direct resale recovery averages roughly 53% of cost, but the real value is in what the panel enables: a home that can support an EV charger, heat pump, and modern kitchen without tripping breakers. Buyers in 2026 increasingly expect 200-amp service, and an outdated panel (especially a recalled brand like Federal Pacific) can stall or kill a sale.
“Net cost after resale” = project cost − resale value added. It's the part you don't recoup at sale, not a loss — most renovations cost more than they return, with the difference buying you the use and enjoyment of the upgrade.
What an electrical panel upgrade (100a to 200a) typically includes
- New 200-amp main breaker panel
- Circuit breaker layout and labelling
- Service entrance cable (if needed)
- Grounding and bonding
- Permit and electrical inspection
Pro tip: If you're adding an EV charger, heat pump, or any large 240V appliance, do the panel upgrade at the same time — bundling the work with one electrician saves a second mobilisation fee and permit.

Before you spend
- Get 3 written quotes from licensed local contractors before committing
- Match finishes to what's normal for your neighbourhood, not above it
- Keep a 10–15% contingency for surprises once work starts
- Avoid overcapitalising — check what comparable homes nearby actually sell for
- If you're selling soon, weigh resale timing against how long the project will take
When electrical panel upgrade (100a to 200a) still makes sense
A 53% resale recoup means electrical panel upgrade (100a to 200a) is primarily a lifestyle upgrade, not a financial play. About $1,200 of the $2,500 spend doesn't come back at resale. That's not necessarily a reason to skip it — it means the decision should be driven by how much you'll enjoy and use the improvement, not by the resale number alone. If you plan to stay in the home for several years and the project genuinely improves your daily life, the unrecouped cost is the price of that enjoyment. If you're renovating specifically to sell, the higher-ROI projects will stretch the same budget further.
