What you are actually paying for

Find the row that matches your situation. Quotes that differ wildly from each other usually differ in scope, not in price.

What moves the price

In descending order of impact. These are also the questions worth asking a contractor whose quote sits outside the range above.

1. 1

   Service size and whether the meter moves

   Replacing a panel in place is far cheaper than relocating the service point, which requires new service entrance conductors and utility coordination.

2. 2

   Overhead versus underground service

   Underground service upgrades require trenching and sometimes a new conduit run from the transformer, which can double the job.

3. 3

   Code upgrades triggered by the work

   Grounding electrode system updates, AFCI and GFCI protection on replaced circuits, and surge protection are commonly required when the panel is replaced.

4. 4

   Aluminum branch wiring or knob-and-tube

   Legacy wiring found during the upgrade must often be addressed, and remediation can exceed the panel cost itself.

5. 5

   Utility scheduling

   The power company must disconnect and reconnect the service. That appointment drives the schedule and occasionally carries its own fee.

Direct answer

Upgrading a residential electrical service panel from 100 amp to 200 amp typically costs $1,800 to $9,000 installed in 2026, with most straightforward overhead-service swaps landing near $2,500 to $4,500. Underground service, meter relocation, long feeder runs, and legacy Federal Pacific or Zinsco replacements push toward the top of the range. The largest variable is not the panel brand but whether the utility must rework the service entrance and how much concealed aluminum or knob-and-tube must be addressed when the scope expands.

What each price band actually buys

Low end

200A panel swap in existing location, overhead service, minimal circuit migration, grounding electrode verification.

Typical

New main breaker panel, labeled circuits, AFCI/GFCI where required on replaced branches, permit and inspection, utility reconnect coordination.

High end

Meter relocation, underground trench, mast and service entrance conductor replacement, or substantial legacy wiring remediation.

Labor vs materials

Typical split for this job nationally: roughly 65% labor and 35% materials. Crew size is usually 1–2 licensed electricians, across one full day plus utility appointment window.

What this price usually does not include

• Whole-house rewiring unless discovered conditions force a change order
• EV charger installation beyond providing adequate capacity
• Generator interlock or whole-home surge protection unless line-itemed
• Trench restoration landscaping after underground service upgrades
• Municipal fees for sidewalk bore or right-of-way work
• Appliance or HVAC electrical rough-in unrelated to the service upgrade

Hidden costs that show up on real jobs

Regional variation

Electrician rates vary 25–50% between high-cost metros and rural areas, while panel hardware is relatively uniform. Coastal cities with strict inspections may require more documentation and return trips. Check `/home/cost/panel-upgrade/[metro]` localized pages when live, and confirm your utility’s disconnect/reconnect schedule—week-long utility delays are common in some co-ops regardless of contractor speed.

Code upgrades this job can trigger

• Working clearances and panel height per NEC
• Grounding electrode conductor and bonding to water/gas where applicable
• AFCI protection on most habitable room branch circuits when extended
• GFCI protection on kitchens, baths, garages, and outdoors when circuits are touched
• Labeling and arc-fault or surge protection where local amendments require

Repair vs replace

Individual breaker replacement or a subpanel addition can solve localized overload without a full service upgrade when a load calculation shows spare capacity. Replace the main panel when you have Federal Pacific Stab-Lok, Zinsco, an obsolete fuse box, insufficient spaces for modern loads, or insurance requires 200A service. If you are adding large loads—EV charger, heat pump, tankless electric—run a load calculation first; sometimes load management avoids a $4,000 upgrade. Panel work is never a repair-versus-patch decision on burn marks, buzzing, or hot breakers—those require immediate professional evaluation.

Timeline and visits

In-place panel upgrades often complete in one day with power off for several hours; utility reconnect may be same day or next business day. Underground or relocation jobs can take two to five days plus utility lead time. Permit inspections are typically scheduled within a few days of completion in active jurisdictions.

Quote checklist — line items a fair bid should show

1. Service size (amps) and main breaker rating
2. Panel brand and number of spaces/circuits
3. Scope of circuit migration and labeling
4. Permit and inspection fees
5. Utility coordination and who schedules disconnect
6. Grounding electrode work included
7. Line item for meter pan or service entrance if needed
8. Warranty on workmanship and manufacturer equipment

Questions to ask before you sign

• Will you provide a load calculation showing 200A is appropriate for my planned loads?
• Who pulls the permit and schedules the utility reconnect?
• What happens if my service entrance conductors are undersized when the panel is open?
• Are AFCI/GFCI upgrades on replaced circuits included or allowance?
• Is the quote based on overhead or underground service—can you verify at the meter?
• What is the payment schedule relative to power being safely restored?

Quote red flags for this job

• Offers to upgrade without permit or inspection
• Cannot explain grounding electrode plan
• Quote assumes 200A without site visit or photos of existing equipment
• Requires full payment before utility reconnect
• Suggests double-tapping or oversized breakers to “make it work”
• No mention of AFCI/GFCI when replacing multiple branch circuits

Payment schedule norms

Many electricians take 25–33% deposit to order gear, balance at passed inspection or successful energization. Avoid paying 100% while power is still off. Larger jobs with trenching may use progress draws tied to inspection milestones.

Seasonality

Demand rises in summer when AC loads trip breakers and in winter when heat pumps and EV charging stack on older panels. Utility appointment availability can be tighter during storm restoration periods.

Can you do it yourself?

When this cannot wait

• Burning smell, scorch marks or a warm panel cover
• Breakers that trip with no identifiable load cause
• A Federal Pacific Stab-Lok or Zinsco panel
• A fuse box in a home with modern electrical demand
