The cost of upgrading or installing an electrical panel in Snohomish County, Washington can vary. Unfortunately, there isn’t a single number to this question. The great thing is: we can give you a general idea of the costs for installing a new electric panel.
For example Melby Electric quotes based on these 4 factors:
- The amp size you’re moving to (100A vs 200A+)
- The condition and layout of existing wiring
- Whether your service needs a true “service upgrade” (meter/main, grounding, mast)
- Local permit/inspection requirements that dictate how the work is done and signed off.
A simple like‑for‑like swap prices very differently than a 200A upgrade that adds capacity for an EV charger, heat pump, or ADU. Here are some clear pricing examples that will help you figure out the general costs.
Pricing breakdown based on type of job in Snohomish County:
- Like‑for‑like panel swap (100A or 150A, no service upgrade, minimal breaker changes): Often $2,000 – $4,000 total in most situations.
- 200A service upgrade (new panel + meter/main + grounding/bonding, typical interior clearance work): Usually between $4,500 – $7,500 when access is normal and mast/conductors are moderate length.
- Higher‑complexity 200A+ upgrade projects (panel relocation, long mast, exterior conduit rework, aluminum remediation, or bundling EV/HP circuits): $7,500-$9,000+.
- A very complex situation (panel move across the home, major rewiring cleanup, long lateral conduit replacement, roofing/patching, or ADU split metering): costs $9,000-$12,000+ on average.
Some pricing changes to consider:
- Aluminum branch remediation, panel clearance corrections, and relocation to meet NEC working space are frequent “surprise” adders that nudge projects into the top half of your band.
- The jump from a “panel swap” to a “service upgrade” is typically $2k – $4k due to meter/mast/grounding and utility coordination.
- Inflation on materials over the past 3 years (copper, breakers, meter bases) keeps the floor higher than before covid, helping explain why $4.5k is a realistic starting point for fully compliant 200A upgrades.
- Snohomish County and city inspections, plus SnoPUD/utility requirements for service equipment, often mandate grounding/bonding updates that add parts and hours even when customers think it’s “just the panel.”
What Goes Into Electrical Panel Costs
Electrical panel installation isn’t a flat number because every home’s system is different. The panel you choose, the condition of your current wiring, and even your city’s inspection requirements all play a part in the final price. It helps to think of the project as more than just swapping a box, it’s about upgrading your home’s entire electrical backbone.
Panel Size
The size of the panel is one of the biggest cost factors. A 100-amp panel is cheaper but may not handle the demands of a modern household. Upgrading to a 200-amp panel gives you more capacity for appliances, charging stations, and future add-ons, but it costs more in materials and labor. For example, a family in Snohomish who recently added a hot tub and EV charger quickly found their 100-amp panel overloaded. Their upgrade to a 200-amp service gave them the breathing room to run new appliances safely and with confidence.
Wiring Condition
Older homes may have outdated or unsafe wiring that can’t support a new panel. If your electrician needs to repair or replace wiring, that adds time and expense. In some cases, this step is essential to bring your system up to code. For instance, homes built before the 1970s sometimes have aluminum wiring or old fuse boxes. Replacing these with modern copper wiring not only supports the new panel but also prevents serious fire hazards.
Permits and Inspections
Snohomish County requires permits for panel replacements, and inspections must be completed before the job is considered finished. These fees add to the overall cost but guarantee the work meets safety standards. A permit may seem like red tape, but it ensures the work is reviewed by a certified inspector who checks that your upgrade meets current codes and is safe for long-term use.
Labor and Complexity
Not all installations are straightforward. Tight spaces, older construction, or unusual layouts can make the job more complex. Extra hours of labor naturally increase the total bill. In one case, a homeowner with a panel tucked away in a cramped basement corner saw labor costs rise because technicians needed extra time to safely re-route wiring. Situations like this are common and highlight why every project’s price can vary.
Typical vs. High-End Costs in Snohomish County
Most homeowners pay between $1,500 and $3,500 for electrical panel installation or replacement. Smaller homes with simple upgrades often fall closer to the low end. However, in cases where heavy rewiring, full service upgrades, or larger 200-amp panels are needed, the cost can climb to $4,500–$7,500. These higher numbers reflect both added materials and the extra labor required for complex jobs.
Signs You May Need a New Panel
Flickering lights, tripped breakers, or burning smells near your electrical panel are all warnings that your system might be overloaded. If you’ve added new appliances or an EV charger recently, it may also be time to consider an upgrade.
Choosing the Right Electrician
Installing a new panel is not a DIY project. It requires licensed electricians who understand Snohomish County codes and permitting. Hiring the right professional means your system will be safe, efficient, and built to last. Local companies like Melby Electric specialize in electrical panel upgrades throughout Snohomish County.
