Electrical panel upgrade costs: a guide with dated price bands
We do residential electrical work only. This guide is about homes.
This guide shows what public sources say an electrical panel upgrade can cost at a home. Every price band has a named source and a date. These bands are not a quote. We price your home after a site visit.
What drives the cost of a panel upgrade
Two homes can need very different work. These are the main reasons.
- Panel only, or the whole service. Some homes need only a new panel of the same size. Others need a bigger service. That can mean new wires, a new meter base or a new service mast. The mast is the pipe on the outside of your house that holds the wires from the utility.
- Size. A larger service costs more. The state fee table has one fee for up to 200 amps and another for 201 to 600 amps.
- Your wiring and where the panel sits. Old wiring, a crowded panel or a hard-to-reach spot adds work. Moving a panel adds more.
- New electric loads. A heat pump, an EV charger, an electric range or an addition can change the size you need.
- Your utility. For work on the weatherhead, meter base or panel, Puget Sound Energy turns off the power so the work can be done safely. PSE says there is a cost for that disconnect and reconnect service, and the cost depends on labor and crew. Other utilities may have their own fees. The national survey below also asks about utility costs that are passed on to the customer.
- Fees. The state sets inspection fees for electrical work. Its fee table is WAC 296-46B-906. Your city or county sets its own permit fees.
Price bands from public data
These bands come from a national survey. They are national numbers, not local ones. We copied the numbers as printed. We did not scale, round or adjust them. Prices checked on October 30, 2026. These bands are not a quote.
Each band shows the middle half of the answers. A quarter of the answers were lower, and a quarter were higher.

How to read these bands
Do not add the bands together. The three bands come from different sets of answers. Prices in Skagit, Snohomish, Island and Whatcom Counties can be higher or lower than a national survey shows.

Questions people ask
Is this a quote?
No. These bands are not a quote. They are public numbers with a source and a date. A quote comes only after we see your home.
Why are the bands national?
We did not find a public survey of panel prices for our counties. We did not scale the national numbers to fit. Prices where you live can be higher or lower.
Why are the bands so wide?
Homes differ in panel size, wiring, where the panel sits and how much the utility must do. The people in the survey also gave answers that were far apart.
Do I need a bigger service for a heat pump or an EV charger?
Not always. It depends on the total load in your home and on what you have now. The site visit is how we find out.
What do the state fees cover?
The state fee table sets the fee for electrical inspections where the state does them. It is not the price of the work. You can read it at WAC 296-46B-906.
Does this guide cover other kinds of buildings?
No. This guide is about homes. We do residential electrical work only.
