One line item, two different jobs.
The $3,500 panel line on your heat pump quote might be a panel swap, or a full service upgrade with meter and service-entrance work. They cost very different money, and most quotes never say which one you're buying.
Two jobs hiding under one name
Published sources genuinely disagree on what a 100-to-200-amp upgrade costs, and the disagreement is informative. Contractor-network data puts the typical job at $1,300–$3,000, with a broader observed span of $800–$4,000. A load-calculation industry guide puts the average at roughly $3,500. Both are real numbers. They are measuring different jobs.
The lower band describes a panel-only swap: new panel and breakers at the same service size the house already has coming in. The higher figure includes service-entrance and meter work, the parts that connect your house to the utility, which many quotes labeled "panel upgrade" quietly exclude. A true full service upgrade can exceed $3,500–$4,500. When two bids for "the same job" land $2,000 apart, this is usually why: they are not the same job.
What's actually in the bill
Each line item tells you which of the two jobs you're being quoted.
| Line item | Typical cost | What it signals |
|---|---|---|
| Panel and breakers | Core of every quote | The swap itself. Present in both jobs. |
| Service entrance + meter box | $200–$650 parts, plus labor | The tell for a full service upgrade. Many panel-swap quotes exclude it. |
| Permit | $50–$500 | Required either way. A quote without it is a red flag, not a discount. |
| Inspection | $50–$200 | Required either way. |
| Utility coordination | Varies by utility | Disconnect and reconnect scheduling. Usually means service work, not just a swap. |
A complete bid itemizes all of this separately. If yours is a single number, ask for the breakdown: whether the meter box and service entrance are in scope is the whole difference between the two price bands above. How to read a quote covers the anatomy line by line.
Panel replacement vs adding a subpanel
These solve different problems, and quotes rarely say which problem you have. A subpanel adds breaker slots. If your panel is physically full but a load calculation shows you have amperage headroom, a subpanel gives new circuits somewhere to land without touching your utility service. It is a smaller job than either version of the upgrade above.
What a subpanel cannot do is create capacity. If the load calculation shows your total demand genuinely exceeds what 100-amp service delivers, redistributing circuits does not change the ceiling, and you need the service upgrade. The decision input is the load calculation, not the electrician's first instinct. Ask to see the math: space problems get subpanels, capacity problems get service upgrades, and paying for the second when you have the first is the expensive mistake this page exists to prevent.
Do you actually need the upgrade?
Often, no. Many electrification projects fit on existing 100-amp service, especially with load-management devices that keep the biggest loads from drawing at once. The panel upgrade is real for some houses, but it is also a common reflex line item, added because it makes the job simpler for the contractor rather than because the load calculation demands it.
The base rates are lower than quotes suggest. Roughly 15–20% of induction range installations trigger a panel upgrade, and the homes that do are typically pre-1990 with less than 100-amp service. If your house is newer than that with standard 100-amp or larger service, treat an unexplained panel line item as a question, not a fact. Ask for the load calculation that justifies it, and get a second bid that prices the project both with and without the upgrade.
What rebates change
In states where the federal HEAR rebate program has launched, income-eligible households can get up to $4,000 toward an electrical panel upgrade and up to $2,500 toward wiring. Households under 80% of area median income can have up to 100% of project cost covered within those caps; 80–150% AMI households get 50%. The caveats are load-bearing: HEAR is live in some states, pending or restricted in others, and some launched states, Arizona among them, only pay the panel cap when it accompanies a qualified appliance install rather than as a standalone project.
One number to ignore: the $600 federal tax credit for panel upgrades that some cost guides still cite. That credit (part of 25C) expired for equipment placed in service after December 31, 2025. Any 2026 quote or article leaning on it is working from stale information. Check what is actually live in your state with the Rebate Matcher.
Where the panel sits in an electrification plan
The panel question belongs at the planning stage, before any equipment contract is signed. If you assess capacity once, against the full list of loads you intend to add over the next decade, you make one panel decision. If you let each project discover the panel separately, you risk paying for the assessment three times and finding the limit via change order mid-install. It is the first infrastructure question in a whole-home electrification plan, and retrofit sequencing covers why order changes total cost.
This is also where the line item usually first appears: buried in a heat pump bid. Heat pump installation cost shows how electrical work fits among the five drivers that move that quote.
Panel upgrade cost questions
How much does it cost to upgrade from 100 amp to 200 amp?
Published figures split by scope. A panel-only swap typically runs $1,300–$3,000, with a broader observed span of $800–$4,000. When the job includes service-entrance and meter work, the average lands around $3,500 and can exceed $3,500–$4,500. Ask which job your quote covers before comparing prices.
Does a panel upgrade include the meter?
Often not. A new meter box runs $200–$650 in parts plus labor, and many quotes labeled as a panel upgrade exclude it. If the utility service to your house also needs to change, that is a full service upgrade, a different and more expensive job. Get the meter question answered in writing.
Can I add a subpanel instead of upgrading?
Sometimes. A subpanel solves a space problem: you have amperage to spare but no open breaker slots. It does not solve a capacity problem: if a load calculation says your total demand exceeds what 100-amp service can deliver, a subpanel just redistributes a limit you have already hit. Ask the electrician to show you the load calculation before choosing.
Do I need 200 amps for a heat pump?
Not automatically. Many electrification projects fit on 100-amp service, especially with load-management devices that prevent large loads from running at once. For context, roughly 15–20% of induction range installations trigger a panel upgrade, and those are typically pre-1990 homes with less than 100-amp service. Run the load calculation before accepting the upgrade line item.
Does insurance require a panel upgrade?
Sometimes, but for a different reason than capacity. Some insurers flag specific legacy panel brands and fuse boxes as fire risks and may decline coverage or require replacement. That is a safety replacement, not a 100-to-200-amp capacity upgrade, and it can be a like-for-like swap. Ask your insurer what exactly they flagged before assuming you need bigger service.
