How Much Does It Cost to Upgrade a 100-Amp to 200-Amp Service in Florida? Signs, Permits & 2026 Pricing

Upgrading a 100-amp panel to 200-amp service in Florida typically costs somewhere from a low four figures to several thousand dollars, depending on your home, your panel location, and how much wiring the utility and inspector require. The final price hinges on things like whether your meter and service entrance need replacing, whether the work is overhead or underground, and local permit fees. Because every home is different, the only reliable number comes from an in-person quote by a licensed electrician.

How much does it cost to upgrade a 100-amp to 200-amp service in Florida?

A 100-to-200-amp upgrade in Florida usually falls in a range from a low four-figure amount to several thousand dollars, with more complex jobs costing more. The main cost drivers are the new panel, the meter and service entrance cable, permits and inspection, and any utility coordination. Expect a higher price if your service mast, grounding, or wiring needs to be brought up to current code.

Here's what tends to move the price up or down:

• Panel and breaker quality. A larger panel with more circuit slots costs more than a basic replacement.
• Overhead vs. underground service. Underground and mast work can add labor and materials.
• Meter and service entrance. If the meter base, mast, or main service cable must be replaced, costs rise.
• Grounding and bonding upgrades. Older homes often need updated grounding to meet today's code.
• Permit and inspection fees. These vary by city and county and are typically a modest share of the total.
• Access and location. A panel in a tight, hard-to-reach, or exterior weather-exposed spot takes more labor.
• Repairs found during the work. Corroded or damaged wiring, common in Florida's humid and coastal climate, may need attention.

Because these factors stack differently on every home, treat any range you read online as a starting point, not a quote.

What homeowners should know

An electrical service upgrade is a permitted, inspected job that should only be done by a licensed electrician. In Florida, utility coordination and local inspection are standard parts of the process, and doing it correctly protects your home and keeps your insurance and resale in good standing.

When should you consider upgrading from 100-amp to 200-amp service?

You should consider an upgrade when your current panel can't safely keep up with your home's electrical demand. More total amperage gives your home headroom for large modern loads without overloading the system.

Common signs it may be time:

• Breakers trip often, or you rely on a crowded, full panel with no open slots.
• You're adding major loads like an EV charger, a heat pump, a pool heater, or a large HVAC system.
• Lights dim when big appliances start up.
• Your panel is very old, shows rust or scorching, or uses an outdated design.
• An inspector, electrician, or insurer has flagged the service as undersized.

If you see burning smells, hot panel covers, or sparking, treat it as urgent and call a licensed pro right away.

Do you need a permit to upgrade electrical service in Florida?

Yes. A service upgrade in Florida requires a permit and at least one inspection, and the utility is usually involved to disconnect and reconnect power. Permit and inspection fees vary by jurisdiction but are generally a small part of the overall project cost.

Your electrician typically pulls the permit, schedules the inspection, and coordinates with the power company. Avoid any contractor who offers to skip the permit — unpermitted electrical work can create safety risks and problems when you sell or file an insurance claim.

How long does a service upgrade take?

Most residential service upgrades are completed in a single day of on-site work, though the full timeline depends on permitting and utility scheduling. Power is usually off for part of the day while the panel and service are swapped.

Plan ahead for the permit approval and any utility disconnect/reconnect appointment, which can add days to the overall schedule depending on your area.

How do you find a trustworthy electrician for this job?

Choose an electrician who is licensed, insured, and experienced with Florida service upgrades, and who provides a written, itemized quote. A good pro will inspect your panel in person, explain what code requires, and handle the permit and inspection for you.

Look for these basics:

• A valid Florida electrical license and proof of insurance.
• Verified customer reviews from real homeowners.
• A clear written estimate that lists the panel, materials, permit, and labor.
• Willingness to pull permits and schedule inspections.
• A straightforward explanation of what your home actually needs.
