What does it cost to replace an electrical panel?

A standard panel replacement runs $1,500–$4,000 installed for most homes. A like-for-like swap of a 100- or 200-amp panel sits low-to-middle. A service upgrade (raising the amperage) is a bigger, separate job at $2,500–$6,000+.

When do I actually need a new electrical panel?

Replace when it's a known-hazardous brand (Federal Pacific/FPE Stab-Lok, Zinsco, older Sylvania), a fuse box, undersized for your needs (60–100 amp that keeps tripping or can't support an EV charger, heat pump, or addition), or showing a burning smell, scorch marks, a warm cover, or repeated trips.

Is an old electrical panel automatically a problem?

No. A reputable modern brand with 100- or 200-amp service that isn't tripping, shows no heat or corrosion, and has open slots is usually fine. Age alone is not a reason to replace a panel; a hazardous brand, a fuse box, undersizing, or signs of failure are.

What's the difference between a panel replacement and a service upgrade?

A panel replacement swaps the box and breakers at the same amperage ($1,500–$4,000). A service upgrade raises the amperage — say 100 to 200 amps — and involves the utility, a new meter base, and often a new service cable ($2,500–$6,000+). Adding an EV charger or heat pump often needs the upgrade, not just a swap.

Can I replace an electrical panel myself?

No. The service entrance stays live upstream of the main breaker, the job requires a permit and inspection, and doing it wrong risks fire, electrocution, and a failed home sale. This is a licensed-electrician job.

What does an electrical panel replacement cost — and do you need one?

Your electrical panel is the heart of the house's wiring: every circuit runs through it, and every safety device that stops a fire or a shock lives inside it. Most panels last a long time, so this isn't a routine replacement — but when a panel is undersized, obsolete, or one of a few known-hazardous models, replacing it is one of the highest-stakes upgrades a home can need. Here's how to tell whether yours is fine, and what a swap actually costs in 2026.

The short answer on cost

A standard panel replacement runs $1,500–$4,000 installed for most homes. A straightforward like-for-like swap of a 100- or 200-amp panel sits at the low-to-middle of that range. Costs climb when the job also involves a service upgrade, a new meter base, moving the panel, or bringing old wiring up to code. See our methodology for how we build these bands.

When you genuinely need a new panel

Replace the panel when it's unsafe, obsolete, or out of capacity — not just old. The clear triggers:

A known-hazardous brand: Federal Pacific (FPE Stab-Lok), Zinsco, or Sylvania panels from the 1950s–1980s have breakers documented to fail to trip. Many electricians and insurers treat these as replace-on-sight.
A fuse box: if your home still runs on screw-in fuses, it's likely 60-amp service — too little for a modern household and hard to insure.
Undersized service: 60- or 100-amp service that keeps tripping, or that can't support an addition, EV charger, heat pump, or electric range you want to add.
Warning signs of failure: a burning smell, scorch marks, a warm panel cover, breakers that trip repeatedly, or flickering lights across the house.
No room to grow: a full panel with no open slots, blocking any new circuit.

When you can leave it alone

A panel that's simply old is not automatically a problem. If yours is a reputable modern brand, has 100- or 200-amp service, isn't tripping, shows no heat or corrosion, and has open slots for future circuits, there's usually no reason to touch it. A single tripping circuit is more often a fault on that circuit than a bad panel — diagnose the branch before you condemn the box. Age alone is not a reason to replace an electrical panel; the reasons above are.

Panel replacement vs. service upgrade — they're different jobs

These two get conflated, and they price very differently:

Panel (load center) replacement: swapping the box and breakers while keeping the same amperage. This is the $1,500–$4,000 job.
Service upgrade: increasing the amperage — say 100 to 200 amps — which also involves the utility, a new meter base, and often a new service entrance cable. Expect $2,500–$6,000+, sometimes more if the utility has to upgrade the drop.

If you're adding an EV charger, a heat pump, or a big kitchen remodel, you may need the service upgrade, not just a panel swap — worth pricing together.

Why this is not a DIY project

A panel replacement means working at the service entrance, where the power upstream of the main breaker stays live even with the main off. It requires a permit and inspection almost everywhere, and doing it wrong risks fire, electrocution, and a failed home sale later. This is a licensed-electrician job, full stop. The upside of hiring it out: a permitted, inspected panel is a clean line item when you sell, not a red flag.

How this affects selling and insuring the home

A hazardous or undersized panel shows up in two expensive places: the insurance quote and the buyer's inspection. Some insurers won't write a policy on a Federal Pacific or Zinsco panel, or on 60-amp fuse service. And a buyer's inspector will flag it, giving buyers a lever to renegotiate or walk. Replacing a known-bad panel before listing removes an objection that scares buyers more than a dated kitchen — the same logic behind fixing what an inspector will flag before you list. If you're mapping out which systems in your home are aging, start with the home maintenance budget so a panel replacement is a planned expense, not a surprise.

The bottom line

Replace the panel when it's a known-hazardous model, a fuse box, undersized for your needs, or showing signs of heat and failure — budget $1,500–$4,000 for a standard swap and more if you're also upgrading service. Leave a sound, adequately-sized modern panel alone. Never DIY it. And if you're planning to sell or add a major electric load, deal with a questionable panel first, because it will surface either way.
