How Much Does a 200 Amp Service Upgrade Cost With a Meter and Mast?
Last updated: August 2026
- A 200A project that involves the meter base, mast/weatherhead, service entrance conductors, or utility coordination generally has a broader scope than a panel-only replacement — a common reason quotes for what sounds like the "same" upgrade can vary widely.
- None of these components automatically need to be replaced. Existing equipment can often be reused if it's adequate for the intended service, acceptable to your utility and local authority having jurisdiction (AHJ), and in suitable condition.
For a full 100A → 200A service upgrade — the kind of project this page focuses on — our reference range is $1,300–$3,000. Estimated national reference range: This is an estimated national reference range based on early (V1) research — not a guaranteed local price. Actual costs depend on your specific project and location. See the full 100A → 200A cost guide for a complete breakdown by scope.
Panel-Only vs Broader Service Work
Not every service upgrade includes every item below — this depends on the existing installation and local requirements.
Panel-focused work typically includes
- Panel / load center
- Breakers
- Related panel work
Broader service work may include
- Meter base / socket
- Service entrance conductors
- Mast / weatherhead, for applicable overhead services
- Grounding / bonding
- Exterior disconnect, where applicable
- Utility disconnect/reconnect or coordination
- Permits / inspection
- Trenching or underground service work, where applicable
What Does the Meter Base Have to Do With a 200 Amp Upgrade?
The meter base (sometimes called a meter socket) is the enclosure that holds your utility's electric meter. It sits between the utility's service connection and your home's panel, and it has to be rated to handle the amperage you're upgrading to.
Whether your existing meter base can stay in place depends on a few things: its rated capacity, its physical condition, and whether your utility and local authority having jurisdiction (AHJ) will approve it for the new service. If it meets those, it may be reused rather than replaced — an electrician (and often your utility) can confirm this by inspecting it directly.
What Does the Service Mast/Weatherhead Have to Do With It?
For homes with overhead electrical service, the mast is the vertical pipe — usually mounted on the roof or an exterior wall — that carries the service entrance conductors up to meet the utility's overhead line. The weatherhead is the fitting at the top that keeps water out of the conductors.
Not every home has one. Homes with underground (lateral) service don't have a mast or weatherhead at all, since the service conductors run underground instead. For homes that do have an overhead mast, whether it needs to be replaced depends on its height, condition, and rating for the new capacity — it doesn't automatically need to change just because the panel is being upgraded.
Service Entrance Conductors
Service entrance conductors are the wires that carry power from the meter (or the utility connection) to your panel. For a 200A upgrade, these conductors need to be rated for the capacity being installed, in acceptable condition, and appropriately sized and routed for your specific setup.
Whether your existing conductors can be reused depends on their current rating, condition, and length — an electrician determines this by inspecting your specific installation. This page doesn't cover conductor sizing or installation steps; that's something to work through with a licensed electrician.
Why Quotes With Meter/Mast Work Can Be Higher
These are possible scope factors, not a guarantee that any one project includes all of them.
- Additional equipment
- Meter bases, masts, and related hardware add material cost beyond the panel itself.
- Additional labor
- More components in the scope generally means more time to install and terminate correctly.
- Utility coordination
- Scheduling a disconnect and reconnect with your utility company adds time that a panel-only job doesn't need.
- Permit/inspection requirements
- Permit fees and inspection scheduling vary by municipality and can add cost and time beyond labor and materials.
- Service entrance condition
- Older or deteriorated service entrance components may need extra work to bring up to standard.
- Grounding/bonding work
- Bringing grounding and bonding up to current code is a common part of a compliant service upgrade.
- Panel relocation
- Moving the panel to a new location, if needed, adds conduit, wiring runs, and labor.
- Overhead vs. underground service
- The type of service you have affects what equipment and labor are involved, and switching between them adds significant scope.
- Trenching
- If the work involves an underground run, trenching and conduit work typically add cost beyond overhead work.
- Existing conditions / code corrections
- Issues found once work begins — like undersized equipment or outdated wiring — may need to be corrected to pass inspection.
A higher quote does not automatically mean the electrician is overcharging — it may simply reflect more scope than a panel-only job. An itemized breakdown is the most reliable way to tell the difference.
How to Read Your 200 Amp Service Quote

- Is the service overhead or underground?
- Is utility coordination included?
- Are permits and inspection included?
- Are grounding/bonding updates included?
- Is an exterior disconnect included if required?
- Is panel relocation included?
- Is trenching included?
Does Every 200 Amp Upgrade Need a New Meter and Mast?
No.
Whether a project needs a new meter base, mast, or weatherhead depends on the existing equipment, your home's service configuration (overhead vs. underground), the condition of what's already there, your utility's requirements, applicable code and AHJ requirements, and the specific scope of your project. Some 200A upgrades reuse most of the existing service equipment; others require replacing several components. Utility and AHJ requirements also vary by location, so the only reliable way to know is to have an electrician evaluate your specific installation.

Frequently asked questions
How much does a 200 amp service upgrade cost with a meter and mast?
It depends on scope. ElectricQuoteCheck's existing reference range for a full 100A → 200A service upgrade is $1,300–$3,000. Meter-base, mast/weatherhead, service-entrance, utility, and other work may broaden the scope when those items need attention. Whether your project falls within that range, above it, or involves additional work depends on the existing installation and local requirements. See our cost guide for more context, or check your own quote with the calculator.
Does a 200 amp service upgrade include the meter?
It may. Many full service upgrades involve the meter base, but whether it's replaced or reused depends on its rating, condition, and what your utility requires — it's worth confirming directly with your electrician.
Do I need a new meter base for a 200 amp upgrade?
Not necessarily. If your existing meter base is rated for the new capacity, in acceptable condition, and approved by your utility, it may be reused rather than replaced.
Does a 200 amp upgrade require a new service mast?
Only if you have an overhead service and the existing mast can't support the new capacity or doesn't meet current requirements. Homes with underground service don't have a mast at all, and an adequate existing mast may not need to change.
Why is my 200 amp service upgrade quote so expensive?
It depends on what's included. Work involving the meter, mast, service entrance conductors, utility coordination, or trenching adds equipment, labor, and permitting beyond a panel-only replacement. A higher quote doesn't automatically mean you're being overcharged — it may reflect a broader scope of work.
What is included in a full 200 amp electrical service upgrade?
It varies, but can include the panel, meter base, and service entrance conductors, plus — for overhead services — the mast and weatherhead, along with permits, inspection, and utility coordination. Not every project includes every item; it depends on the existing installation and local requirements.
Is a panel upgrade the same as a service upgrade?
Not necessarily. A panel upgrade can mean just replacing the panel and breakers, while a service upgrade can also involve the meter, service entrance conductors, and related equipment that determine how much capacity actually reaches the panel.
