A service upgrade looks like one job. It's actually two — one on the utility's side of the meter, one on yours — and they happen on different schedules with different invoices. Quoting only the electrician's number is how owners blow the budget by 20-30%.
The catch most cost-guide aggregators flatten: the meter base, the weatherhead, and the disconnect/reconnect fee live outside the electrician's line item. So does the AFCI cascade if the upgrade gets paired with a substantial reno. Plug your scope through the electrical rewire cost calculator before signing a quote — the calc's service-upgrade-only mode surfaces the lines the aggregators skip.

How a 200A upgrade actually breaks down
The headline number is the sum of four lines that move on different inputs. Treat it as one line and you'll quote the cheap version of the job. Here's the editorial walkthrough; the calc engine sums these explicitly with leak-flag modulation.
| Line | Side | Typical band | Anchor |
|---|---|---|---|
| Panel + main breaker | House | $300-$400 indoor / $500+ outdoor (materials) | Fixr 2026 brand-pricing tables (Square D, Eaton, GE, Siemens, Leviton) |
| Service entrance + meter base | Both | $400-$1,500 materials + labor | Driven by weatherhead height + meter relocation |
| Utility coordination | Utility | $100-$400 disconnect/reconnect fee | Local utility tariff; usually a separate invoice |
| Permit + inspection | Municipal | $250-$500 clean / $500-$1,500 strict | Inspection $125-$250 per visit (Fixr 2026) |
Bands above are SiteworkMath planning ranges informed by Fixr 2026, Inch Calculator 2026, and Nassau National Cable cost-guide data captured under verbatim quote in the persistent competitor intel. Verify against a local electrician quote and your utility's tariff schedule before locking the budget.
What forces a clean upgrade into a full rewire
The whole point of quoting service-upgrade-only is to keep the existing branch circuits in place. Three things reliably wreck that plan when the inspector walks through. The calc engine handles these with explicit scope-promotion logic; this section is the editorial version.
- Knob-and-tube wiring found in the cavity.K&T anywhere in the house — even one feed running through the attic — will not pass a partial inspection in most Chicago-metro jurisdictions. The inspector force-promotes to full rewire scope at the rough-in. If you're upgrading service on a pre-1950 home, run the K&T-replacement scope at the same time; finding it mid-project is how the $4K upgrade becomes a $20K project.
- Aluminum branch wiring (1965-1973 stock).Aluminum on the branch side won't pass termination at a new 200A panel without CPSC-compliant connector treatment (COPALUM crimp or AlumiConn) or copper-replacement scope. Plain wire-nut pigtailing is not compliant per CPSC. Quote the aluminum remediation scope before the panel; the panel install is the moment the inspector enforces it.
- NEC 210.12 AFCI cascade on substantial renovation. If the service upgrade is paired with a kitchen, bedroom, or living-room reno, NEC 210.12 cascades AFCI breakers across every circuit serving those rooms. AFCI breakers run $40-$100 each in Fixr 2026 materials; a 6-AFCI cascade is $400-$800 the service-upgrade quote rarely includes. Surface it before the bid.
How a Chicago-metro 200A upgrade actually went
A 2020 gut rehab on a bank-owned Chicago-metro single-family — 1,650 sqft single-story pre-1940 — needed the 60A fuse panel taken to 200A to support a new electric range, electric dryer, and a future EV charger. The walkthrough quote from the licensed electrician was $3,200 for panel + service entrance: defensible against the Fixr 2026 band. What the quote didn't include: the utility's disconnect/reconnect fee ($240 separate invoice), the meter-base relocation needed to comply with current weatherhead-height code on the lot ($580 in additional labor + materials), the permit ($380), and inspection at $200 per visit across two visits because the inspector required a re-look on the grounding electrode bond.
Net delivered: $4,800 against a $3,200 quote. Not a contractor screw-up — the contractor priced what they were asked to price. The owner-side budget didn't add the four lines outside the electrician's scope. The discipline I'd wire into any service upgrade now: get the electrician's quote, then add 25-40% for the lines that don't live on their invoice. Permit + utility + meter-side work is real money and never less than a few hundred dollars. The cost of being conservative on the budget is much smaller than the cost of being surprised at the meter pull.
What drives the cost — line by line
Pulling the four lines apart and looking at what moves each one. The calc engine drives these explicitly; here's the editorial walkthrough.
- Panel materials by amperage. Per Fixr 2026 brand-pricing tables, 200A indoor panels run $300-$400 in materials (Square D, Eaton, GE, Siemens, Leviton). Outdoor panels are $500+. Brand price spread is real — the same 200A capacity ranges from $80 on the Eaton low end to $2,300 on the Eaton high end depending on interrupting capacity, breaker count, and surge protection. Spec the panel before quoting; brand-tier choice is where the materials line spreads.
- Service entrance + meter base. If the existing weatherhead and meter base meet current code and amperage capacity, this line is mostly labor — pull the meter, swap the panel, reconnect. If the meter base is rotted, undersized, or installed at a non-current-code height, it has to be relocated. Relocation adds $500-$1,500 — the surprise line on older homes.
- Utility coordination.The disconnect/reconnect fee is a separate utility invoice — typically $100-$400 in the Chicago metro depending on the utility (ComEd vs. small municipals vary meaningfully). The fee buys the utility's time to physically pull and reset the meter. It's not optional, and it's never on the electrician's quote unless they explicitly say “all-in including utility fees.”
- Breakers + AFCI/GFCI cascade.AFCI breakers run $50-$100 per Fixr 2026 materials; GFCI breakers run $5-$100. (Inch Calculator's $15-$25 figure is for breaker REPLACEMENT in an existing panel, labor included — not new-install materials, so it doesn't apply on a service upgrade.) On a service-upgrade-only scope (existing branch wiring kept), the breaker count usually transfers 1:1. On any scope that includes a substantial reno, the AFCI cascade ramps the breaker line.
- Permits + inspection. Per Inch Calculator $50-$350 in clean jurisdictions; per Fixr 2026 $50-$300 panel-work permits with $300+ in strict jurisdictions; per Nassau National Cable $25-$1,000+ jurisdictional spread. Chicago-metro reality: $250-$500 for a residential service-upgrade permit in a clean jurisdiction; $500-$1,500 in strict jurisdictions with structural-reviewer requirements. Inspection itself is $125-$250 per visit per Fixr. Multiple visits are common when the inspector requires a re-look on grounding.
Where this number breaks down
The traps that put the budget on the wrong side of reality:
- EV charger or electric heat retrofit changes the math. If the upgrade is driven by a new EV charger circuit, the dedicated 240V outlet + wire run is its own scope and runs $500-$2,000 on top of the panel work. Electric-heat retrofits with multiple high-load circuits push that further. The 200A capacity is the prerequisite, not the answer; budget the load on top of the upgrade.
- Strict-jurisdiction permits double the calendar window. A clean Chicago-metro jurisdiction is 1-3 weeks of permit-and-inspection calendar time. Strict jurisdictions with structural-reviewer requirements push that to 5-10 weeks. Calendar time is a real holding cost on a flip; if the property is mid-rehab and the rest of the rehab depends on power, plan the upgrade for after demo and before drywall close.
- Meter relocation is the surprise line.On homes where the existing meter base is on a bay wall, an addition wall, or a rotted exterior, the relocation cost is $500-$1,500 outside the panel quote. Walk the meter side of the property with the electrician before signing — the relocation is the line they spot and the homeowner doesn't.
- Working-space code (NEC 110.26) on garage/basement installs. A 200A panel needs 30 inches of clear width and 36 inches of clear depth in front of it per NEC 110.26. On homes where the existing panel was installed in a closet or behind a water heater, the new 200A panel has to be relocated to comply — that's drywall + framing + plumbing work that lives outside the electrical line entirely.
Frequently asked
How much does it cost to upgrade from 100 to 200 amp service in 2026?
Most homeowners land in the $1,800-$4,500 band per Fixr 2026 cost-guide pricing for a typical 100A→200A upgrade on a 1,500-2,500 sqft home. Inch Calculator and Nassau National Cable both anchor a tighter $1,500-$3,000 range for the panel + service-entrance work, with utility coordination + permit + inspection adding $300-$1,500 on top depending on jurisdiction. The number that moves the band is whether the meter base needs to be moved or replaced — meter relocation is the surprise line that cost-guide aggregators flatten.
Is 200 amp service enough for a modern house?
200A is the default for new residential construction and the realistic minimum for any home with electric heat, an EV charger, a hot tub, electric range + electric water heater, or a finished basement carrying its own dedicated circuits. 100A is fine for older homes running gas heat, gas range, gas water heater, no EV — typical pre-1990 single-family stock without high-amperage retrofits. The specific question is whether your largest combined load fits inside 100A with NEC's load-calc safety factor; if not, you're upgrading regardless of comfort. 400A service shows up on luxury residential and small multi-unit, not standard single-family.
Do I need a permit to upgrade my electrical service?
Yes — service-entrance and panel work is permit-required in every jurisdiction I've worked in across the Chicago metro and Michigan. Per Fixr 2026, panel-work permits run $50-$300 in clean jurisdictions and $300-$1,000+ in strict jurisdictions with structural-reviewer requirements. Chicago-metro permit fee schedules typically land $250-$500 for a residential service upgrade; the inspection itself is $125-$250 per visit. The utility company also charges a separate disconnect/reconnect fee on the meter side (usually $100-$400), which sits outside the electrician's quote and is the most-missed line on DIY budgets.
How long does a 200 amp service upgrade take?
The labor portion is typically 1-2 days for the electrician — pull the meter, swap the panel, reconnect branch circuits, terminate the new service entrance. The calendar window is the harder number: utility coordination for the meter pull + reconnect adds 1-3 weeks in clean Chicago-metro jurisdictions, and 5-10 weeks in strict jurisdictions where the inspector requires multiple rough-in visits. Schedule the upgrade for a season the household can lose power overnight if the utility's reconnect window slips. The labor day count and the calendar day count are different numbers; budget the calendar one.
Can I upgrade my own electrical service?
In most jurisdictions, owner-occupants can pull their own residential electrical permit on a primary residence. Service-entrance work is the part of residential electrical I'd push back hardest on owner-installed: the meter-side coordination with the utility requires a specific scope of work agreement, and the inspector who passes the new service has to sign off on grounding (NEC 250), service-entrance termination (NEC 230), working space (NEC 110.26), and panel installation (NEC 408) all at once. For investor-flips and rental properties, almost no jurisdiction allows owner-installed service work — licensed electrician required. Realistic owner-installed path is the panel swap on an already-correct service, not the service upgrade itself.
Will a 200 amp upgrade trigger a full rewire?
Not by itself — a service-upgrade-only scope keeps the existing branch circuits in place and changes only the utility-side amperage + the panel + main breaker. Three things flip a clean panel-and-service swap into a partial or full rewire at the inspector's walk-through: knob-and-tube wiring found anywhere in the cavity (forces full rewire in most Chicago-metro jurisdictions), aluminum branch wiring (forces COPALUM remediation or copper-replacement scope), and substantial renovation triggering NEC 210.12 AFCI cascade on bedroom + living-room circuits. If any of those are in play, get the rewire scope quoted at the same time as the service upgrade — discovering them mid-project is how the budget breaks.
What I'd do next
- Run the service-upgrade scope through the calc
Service-upgrade-only mode keeps the branch wiring in place and surfaces the four lines (panel + service entrance + utility + permit) plus any leak-flag promotion from K&T or aluminum.
- Compare against a full or partial rewire
If the inspector force-promotes scope at rough-in, you're in rewire territory — see how the four scope modes compare before the bid.
- Wire the upgrade into a full gut-rehab budget
Service upgrade is one line of fourteen on a gut rehab. Use this if the upgrade is part of a larger scope decision.
Also in this cluster
Once the service-upgrade scope is locked, the next decision is whether existing branch wiring will pass termination at the new panel — that's where K&T or aluminum forces scope creep. Run the rewire calc alongside this one if either is a possibility on the property.
