Service entrance, meter equipment and utility coordination for homes that need more than a new panel.
An electrical service upgrade in Bothell, WA replaces or enlarges the equipment that carries power from the electric utility into a home, usually to add capacity or renew aging parts. That pathway includes the service entrance conductors, the meter equipment, and the main disconnect, and it is distinct from the breaker panel inside the house.
Bothell spans King and Snohomish counties, so the utility at the other end of your service depends on the address, and service changes usually involve the utility's own requirements and scheduling. This page sorts out what the project covers, what belongs to your electrical contractor, and what belongs to the utility.
A service upgrade is easiest to understand one component at a time.
The electrical service is the pathway that brings power from the utility into the building, ending at the main disconnect. Downstream of it, the electrical panel divides that power into individual circuits. A panel upgrade renews the panel alone, while a service upgrade renews the pathway and its capacity.
Main service equipment is the collective term for the hardware at the head of that pathway: the meter socket, the main disconnect that can shut off all power, and any combination unit housing both. During an upgrade, this equipment is sized to match the new capacity and to satisfy code requirements.
Service entrance conductors are the large cables running between the utility's connection point and the main disconnect. On overhead services they travel from the weatherhead, the fitting where overhead conductors enter, down to the meter; on underground services they rise from a buried lateral. Their size sets how much current the service can safely carry.
The meter and the socket that holds it are where the utility measures usage. Meter equipment sits at a boundary: the utility typically owns and seals its meter, while the socket, conduit, and conductors around it are generally part of the customer-side installation. Ownership details get confirmed during planning.
Service capacity, expressed in amps, describes how much power the service can deliver at one time. Capacity depends on the whole chain: the conductors, meter equipment, main disconnect, and panel all need ratings that support it. Many older homes were built around smaller loads, so their services reflect an earlier era.
Capacity limits rarely announce themselves with a single symptom.
Remodeled kitchens, home offices, and well-equipped garages each add modest demand on their own. Together, that demand climbs. When breakers trip as several appliances run at once, the limitation may sit with the service rather than any single circuit, and an assessment can tell the difference.
Some homes still run on services sized for lighter loads than the household now places on them, leaving little headroom above the original design. Warning signs include a shortage of breaker space and a main breaker that looks small next to modern demands. A load calculation compares the existing rating with how the home lives today.
Finishing a basement, adding living space, or rebuilding a kitchen usually adds circuits beyond what the existing panel was designed to hold. When a remodel's electrical scope outgrows the panel and the service behind it, upgrading the service keeps the finished space from straining original equipment.
A Level 2 charger, the 240-volt charging unit many homeowners install, draws a continuous load, and the National Electrical Code recognizes EV charging equipment as exactly that. Some services absorb a charger with load management, which lets it share capacity with other household loads; others need service capacity first. Our EV charger installation in Bothell page covers that decision.
Converting a gas furnace or water heater to a heat pump moves that workload onto the electrical service. Add an electric range, a dryer, and an EV charger, and the combined demand can approach what an older service was built to deliver. Electrification planning often starts at the service.
Every project is scoped case by case. Some items belong to the homeowner side of the meter, while others fall to the utility or need utility coordination before work can proceed, and that split is identified before quoting rather than after.
This common capacity upgrade replaces an older 100 amp service with a 200 amp service, giving a home room for modern loads. Scope typically includes new service entrance conductors, meter equipment, and a main disconnect rated for the higher capacity, plus the panel work behind it, which our 100 amp to 200 amp panel upgrade page covers in detail.
Overhead service reaches the home from a utility pole, entering through the weatherhead above the meter. House-side scope can include a new mast or riser, the weatherhead, and new conductors. The overhead line from the pole to the home belongs to the utility, so that portion is scheduled through them.
Underground service arrives through a buried lateral instead of an overhead drop. Contractor scope can include the conduit run, conductors, and the connection at the meter, while the utility typically handles its portion of the lateral. Trenching depth and routing follow the utility's standards, confirmed before any digging starts.
Some projects replace aging or damaged meter equipment and service entrance conductors without changing capacity. Because the utility seals and relies on its meter, this work is coordinated so the meter can be removed and reset on the utility's schedule, with power safely off during the swap.
Bothell spans King and Snohomish counties, so the electric utility behind an electrical service upgrade in Bothell, WA depends on the address: many homes are Puget Sound Energy customers, while addresses on the Snohomish County side may be served by Snohomish County PUD. Confirming the provider comes first, because a service change usually involves the utility's own requirements and scheduling rather than the electrical permit alone. A utility may review the planned configuration, disconnect and reconnect power, pull and reset its meter, or schedule line-side work, and those steps run on the utility's timeline. Homeowners never have to guess which provider applies; we confirm it by address during the assessment. Projects get sequenced around that process so the home spends as little time without power as the utility's steps allow. Permits remain electrical permits through Washington L&I for Bothell addresses, as the City of Bothell Permit Center lays out, and utility coordination runs alongside that permit process rather than replacing it.
Cost in Bothell is built from scope, not from a flat rate, and the main factors are predictable. Service amperage matters, because raising capacity calls for larger conductors and equipment rated to the new level. Overhead versus underground configuration changes the labor involved, since underground work can add trenching and conduit routing. Meter equipment, service entrance wiring, and main panel replacement each carry their own scope. Utility-related work affects both cost and schedule when the utility's side of the service needs attention. Grounding updates often accompany an older service being brought to current requirements, and the permit and inspection belong in every complete quote. An electrical service upgrade in Bothell, WA gets priced from the assessment, after the utility's role is identified.
| Typical electrical service upgrade in Bothell | Range* |
|---|---|
| 100 amp to 200 amp upgrade, panel and meter stay in place, overhead service | $4,000-$7,000 |
| Full service upgrade including meter and service entrance work | $8,000-$16,000 |
| Panel relocation or meter and mast work | $10,000-$20,000 |
Published Puget Sound ranges put a full 100 amp to 200 amp service upgrade between $8,000 and $16,000, with straightforward upgrades that leave the panel and meter in place running $4,000 to $7,000, and panel relocation or meter-and-mast work reaching $10,000 to $20,000. Utility charges and the state permit fee are separate line items we show plainly. The written estimate after the assessment, once the utility's role is known, is the definitive number.
Service calls often mix two different questions: what the panel needs and what the service itself needs. Before quoting, we separate panel-level work from true service work, meaning the conductors, meter equipment, main disconnect, and the utility connection. The quote then covers what the home actually requires, nothing gets replaced for the sake of it, and utility-owned items stay out of the price where they do not belong.
Every service upgrade is permitted and inspected through Washington L&I's electrical permit and inspection process, whose inspectors use the 2023 National Electrical Code. Nothing about our licensing is a claim you must take on faith: Washington L&I's VerifySALI contractor lookup records our licensed, bonded and insured Washington electrical contractor status. Permits are filed online through L&I's system, and the required inspection is scheduled as part of the project, not left for the homeowner to chase.
A service project runs on two schedules: the contractor's and the utility's. We keep you informed about both, from what the utility requires to when its crew is expected and what happens inside your home each day. Calls are answered 24 hours a day, so a question about the power, or an urgent electrical concern during the project, never waits until morning.
Pricing follows the scope found during the assessment: target amperage, overhead or underground configuration, meter equipment, service entrance wiring, whether the main panel is replaced, and any utility-related work. Full service upgrades with meter and service entrance work typically run $8,000 to $16,000 in this corridor, while straightforward upgrades that keep the panel and meter in place run less. Because those variables differ from house to house, quotes come from an on-site evaluation rather than a general number.
A panel upgrade replaces the breaker panel that divides power into circuits. By contrast, a service upgrade renews the pathway that brings power from the utility into the home: service entrance conductors, meter equipment, and the main disconnect. Many projects involve both, and each side is scoped separately so you only pay for what is needed.
Not every home does. A load calculation weighs existing and planned demand, including appliances, heat pumps, and EV charging, against the current service rating. Homes with large electrification plans often land on 200 amps, while others run comfortably on less. The calculation drives the answer, not a rule of thumb.
Usually, yes. Service changes typically involve the utility's own requirements, which can include reviewing the planned configuration, disconnecting and reconnecting power, and handling its meter and line-side equipment. Those requirements and schedules differ between utilities, so we identify your provider by address and coordinate the utility's steps as part of the project.
The utility typically handles its own meter equipment, while the electrical contractor handles the service side: the meter socket, service entrance conductors, and main disconnect. Exactly which parts each party owns and performs is confirmed during planning, and the meter is removed and reset on the utility's schedule while the work proceeds.
Often, yes. Some services have enough headroom for a Level 2 charger, and load management devices can let a charger share capacity with the rest of the home. Our article on EV charger load management explains how that works, and an assessment shows whether your home needs that step or a service upgrade first.
The on-site electrical work is usually the shortest part of the project. Planning, permitting, and especially the utility's scheduling for disconnects, meter handling, and reconnection shape the overall timeline, and timing varies by utility and by project. After the assessment, we lay out the expected sequence before work begins.
If the service feels undersized for the way your household lives, or a renovation and new loads are on the horizon, an assessment is the place to start. We will evaluate the existing equipment, confirm your utility's role, and lay out the project step by step.
