A residential electrical heavy-up typically costs $2,000-$6,000, with an average near $3,800 for upgrading a 100-amp service to 200 amps. The final price depends on the panel and meter equipment, utility work, wiring condition, permits, and whether the service entrance needs replacement.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 200-amp service upgrade | $2,000 | $3,800 | $6,000 | Typical panel, meter, and service work |
| Panel replacement only | $1,200 | $2,300 | $4,000 | Existing service capacity retained |
| 200-amp upgrade with extensive repairs | $4,500 | $7,000 | $10,000+ | May include rewiring, mast, or service relocation |
What a 200-Amp Heavy-Up Usually Costs
For a straightforward upgrade from 100 amps to 200 amps, homeowners commonly pay $2,000-$6,000. That range generally covers a new main panel, meter base or socket as needed, service conductors, grounding and bonding updates, labor, and standard inspections. A 150-amp upgrade may cost $1,800-$4,500; a 400-amp service for a large home or substantial electrical load can reach $5,000-$12,000 or more.
Budget about $3,800 for a typical 200-amp project with clear access and no major code or utility complications. Older homes, overhead service masts, long conductor runs, or equipment relocation can push the quote above the usual range. Assumptions: U.S. home, standard-quality equipment, accessible panel, ordinary labor, and no extensive branch-circuit rewiring.
How Panel, Meter, and Labor Charges Add Up
Quotes vary in what they include. The breakdown below shows common line-item ranges for a 200-amp upgrade; combined amounts are not necessarily additive because contractors may package equipment and labor together.
| Quote item | Typical range | Pricing basis | What it covers |
|---|---|---|---|
| Main panel and breakers | $500-$1,500 | Per panel | Panel, standard breakers, and installation materials |
| Meter socket and service conductors | $400-$1,500 | Per service | Meter equipment and cables, depending on run and utility setup |
| Electrician labor | $800-$2,500 | Per project | Often 8-16 hours for a straightforward replacement |
| Permit and inspection | $50-$500 | Per permit | Local application and inspection fees |
| Mast, grounding, or repairs | $300-$2,000+ | Per job | Extra work for deteriorated or noncompliant service parts |
Electricians may charge roughly $75-$150 per hour, but many quote the job as a fixed price. Confirm whether the estimate includes utility coordination, inspection, breaker labeling, and disposal of old equipment.
Which Service Specs and Site Conditions Raise the Quote
Capacity is a major cost driver: a 200-amp upgrade usually requires less equipment and labor than a 400-amp service, while the utility must confirm that the larger capacity is available. A service run longer than about 50 feet, a difficult route, or an overhead mast needing repair can add several hundred to more than $2,000.
Panel location also matters. Moving equipment to another wall or outside the home can add roughly $500-$2,500, depending on conductor routing and wall repairs. Knob-and-tube wiring, undersized grounding, damaged service cables, or a crowded panel may require additional corrections. Ask the electrician to identify these as separate, priced items rather than burying them in a single allowance.
Get the capacity, service route, and included code corrections stated in writing; those details explain most large quote differences. Utility-side work may be performed or billed separately by the local utility, so ask whether the estimate includes only customer-owned equipment.
How to Lower a Heavy-Up Quote Without Cutting Capacity
Compare at least three licensed electricians using the same scope: amperage, panel brand or equivalent, meter work, grounding, permit, inspection, and utility coordination. A lower quote may exclude a new mast, permit fees, or repairs discovered after shutdown. Request separate prices for required safety work and optional upgrades.
Keeping the panel in its current location can avoid substantial rerouting costs. If the existing service entrance and meter equipment are in good condition and approved for reuse, ask whether they can remain; local code and utility rules determine whether that is allowed. Avoid adding circuits or premium monitoring features unless they solve a current need.
How Regional Rates and Utility Rules Shift Prices
Urban areas with higher wages and permit fees may run 10%-25% above a similar rural project. Rural jobs can also cost more when travel is long or the nearest contractor is far away. Coastal markets and regions with older housing stock may see higher estimates when corrosion, outdated wiring, or stricter local requirements add work.
Utility rules differ by service territory. Some utilities require a specific meter socket, disconnect arrangement, or service design, and may schedule a temporary shutoff or reconnection. The electrician should verify requirements before ordering equipment. Permit fees are commonly $50-$500, but local rates and inspection requirements vary.
Compare local quotes against identical equipment and utility scope, not just the headline total. Ask whether the utility charges for a new connection or service change, since that amount may not appear on the electrical contractor’s estimate.
How Long the Electrical Crew and Utility Work Take
A standard service upgrade often takes one electrician and an assistant about 8-16 labor hours, typically completed in one day when access is clear and equipment is available. A panel move, service mast replacement, extensive grounding work, or repairs to existing wiring may extend the job to two days or more.
Power is usually shut off during the changeover. Utility coordination can add days or weeks to the calendar, especially if a utility crew must disconnect and reconnect overhead or underground service. Confirm who books the outage and whether temporary power or a second visit would create an extra charge.
When Panel Replacement Is Cheaper Than a Full Upgrade
A panel-only replacement may cost $1,200-$4,000 when the existing service capacity, meter, and conductors can safely remain. It does not increase available amperage, so it may not resolve frequent breaker trips or support added equipment. A full heavy-up is more appropriate when a load calculation shows the existing service is insufficient or the utility and electrician require new service equipment.
For a new electric range, heat pump, workshop, or electric-vehicle charger, request a load calculation before choosing 200 amps or more. In some homes, a subpanel or managed-load device may be less expensive than a service increase, but it cannot substitute for inadequate capacity in every situation. Choose the scope based on calculated load and required repairs, not panel size alone.
Which Add-On Charges Should Appear Before Work Starts
Common extras include $300-$1,500 for a service mast, $200-$800 for grounding or bonding corrections, and $500-$2,500 for relocating the panel. Wall patching and painting may be excluded, as may trenching for underground service. Ask for a written change-order rate if concealed damage or unsafe wiring is found after the panel is opened.
Check whether disposal, permit handling, inspection corrections, and new breakers are included. Some specialty breakers cost $40-$150 each, while standard breakers may be included with the panel. A clear quote distinguishes mandatory code work from optional additions and states how any utility charges are handled.
