Upgrading an Electrical Panel Cost

How Much Does Upgrading an Electrical Panel Cost?

low costLow: $800-$1,200average costMedium: $1,500-$3,000high costHigh: $2,000-$4,000

Power from the electrical company's line flows through a home's outside meter and into the electrical service panel, which controls the flow of electricity into the house. Total electrical usage cannot exceed the panel's capacity, which can be 100, 150, 200 or 400 amps. Homes may also have sub-panels that are located elsewhere, which are smaller versions of the main panel and wired through it.

Typical costs:

  • Typically it costs $800-$1,200 to have a qualified electrician upgrade an existing panel to 100 amps, or $1,500-$2,500 if a new panel is needed.
  • Expect to pay $1,300-$3,000 to upgrade to 200 amps, or $2,000-$4,000 to go to 400 amps.
  • Installing a new sub-panel runs $500-$1,000.

What should be included:
  • Electrical panels in an older home might have a lower capacity, but 100 amps is the current minimum required, while 150 amps is common. Many new homes are being built at 400 amps, which usually is achieved by using a 400-amp meter and two 200-amp panels.
  •[1] describes and illustrates a typical main electrical panel, while[2] provides a detailed glossary of electrical terms, which helps in understanding exactly what is included in a quote or required in a specific situation.
  • This is not a do-it-yourself project; major wiring changes should be done by a licensed electrical contractor. Check with your local planning department for any local restrictions or requirements; generally a permit is needed. Permit costs vary widely nationwide.
  • If needed, the upgrading process can include repairing old wiring, adding a copper grounding pole, and removing and replacing the old panel.
Shopping for upgrading an electrical panel:
  • Get estimates from several companies or contractors. Make sure the electrical contractor is properly bonded and insured, as well as licensed in your state.
  • Referrals to electrical contractors are available from the National Electrical Contractors Association[3] .

I had to replace my electrical panel in an emergency situation. This contractor took a $10K advance without looking into what needs to be fixed and then submitted an invoice of $20K after fixing it. I need to know what he did (and didn't do) and if he is over-charging me.

100 to 200Amp service change
Amount: $800.00
Posted by: Old sparkey in BillericA, MA.Posted: April 24th, 2017 06:04PM
Amps: 200Electrician: Tom
For you people getting a service change. A heads up the material on a simple one is about 800$ our cost. We charge on the difficulty on the outside and if your existing panel is loaded up and how many circuits. The arc fault breakers are expensive about 45$ our cost and required in all circuits except garage and bathrooms.
So a good price ball park is 2300-2800$ depending plus I he permit . Do not allow anyone to do a service change without a license!! Good luck

After searching websites such as Craigslist Long Island & Angies List we spoke to a few of our neighbors at a local event who had all used the same company thru word of mouth. Daly Brothers upgraded our panel with permit for $1800.00. They were extremely professional and in and out in the same day. Their work was clean and the organized and labeled our entire panel which was never done previously. They are a General Contracting Company who handle all aspects of home improvements and specialize in electrical work. They were recommended and we will definetly be using them again on any future upgrades or home improvements! 5 stars ⭐️⭐️⭐️⭐️⭐️

I wanted my breaker box upgraded to 200 amps. I was referred to Leroy from a family member. I was quoted two other prices from other electricians and he wasn't the highest but not the lowest either. I decided to go with him as I was advised and could not be happier. He was professional, on time, neat, and even did some other work that was not originally quoted. I referred him to a friend that needed electrical work done and she's very satisfied as well.

Replacing electrical panel
Amount: $3,700.00
Posted by: Evelyn M. in Richmond, TX.Posted: March 5th, 2015 04:03AM
Amps: 240Electrician: Universal
We had an electrical problem with a faulty wire from the pool breaker to the pump. The electrician came out and noted out Electrical panel was not up to code. It was 25 years old and had aluminum wiring into the panel. It showed signs of arc'ing--he said. I called my dad who spend over 40 years in the industry and he told me to change it out. The total bill was $5100 but the remainder was to run a new pool conduit and not related to the electrical panel replacement. It came with a 10 year warranty. Replaced March, 2015. This site only has "2014" loaded.

The full service also included a new door bell installation, and two dead outlets being repaired. The electrician at the outside box did great work. The company sent two less experienced persons to do the inside outlet repairs and door bell work. Those two were not good at all. They did not test theirs repairs and had to be called back into the house from the truck. I did get a lifetime service contract on the whole package- but I think the work was overpriced by about $1,000.

Panel Upgrades
Amount: $2,000.00
Posted by: DSiggy60 in Union, ME.Posted: August 2nd, 2013 03:08AM
Just a note on panel upgrades. For a majority of the states electrical code panels (2011 National Electrical Code), when upgrading a panel, a majority of breakers must be replaced with the Arc-Fault type. this may increase the past cost of the job by as much as $50 a breaker.

John(the owner) did a very neat and clean 200 amp service upgrade for me at my home in richboro, pa. My existing panel was way to small and my outside service cable was cracked and dry rotted. I am a realtor and I have recommended and used him on numerous service upgrades and panel changes. The best part is that he always answers the phone personally and does the work himself.
