Electrical Panel Upgrade Cost in Arizona

Arizona has one practical detail that affects almost every panel upgrade in the state: knowing which utility serves your home determines how your electrician coordinates the job, and in the Phoenix metro that means knowing whether you're an APS or SRP customer. Arizona Public Service and the Salt River Project divide the Phoenix metro between them — APS covers the northwest valley and most of the core city; SRP covers the east valley (Mesa, Chandler, Tempe, Gilbert, much of Scottsdale). Tucson runs on Tucson Electric Power. The coordination process is essentially the same across all three, but your electrician needs to know which entity to contact before scheduling starts.

Cost-wise, Arizona sits at or slightly below the national average. A standard 100-amp to 200-amp upgrade in the Phoenix metro runs $1,800–$4,500 all-in — permits, labor, and utility coordination included. One thing worth knowing upfront: because Arizona has no statewide electrical code, permit fees vary by city — Phoenix, Scottsdale, Tempe, Mesa, Chandler, and Tucson each set their own, and your electrician includes them in the quote.

What Arizona homeowners pay

The table below reflects 2026 pricing for the most common panel upgrade scopes in Arizona. All-in costs include labor, the new panel and breakers, electrical permit fees, and utility meter coordination. They exclude meter base replacement, panel relocation, and service entrance work — those are add-ons when your electrician finds the existing infrastructure needs it.

Tucson tends to run slightly lower than the Phoenix metro across all scopes. The statewide column captures the full spread, including Flagstaff and rural Arizona markets where contractor supply is thinner and travel time can push prices higher.

The 200A→400A row deserves a note. Arizona's extreme heat load — central AC running at full capacity for five or six months a year — means a 400-amp service question comes up far more often here than in most states. A Phoenix-area home with central AC, an EV charger, a pool pump, and solar with battery storage can realistically approach a 200-amp panel's capacity. If you're adding solar and an EV charger simultaneously, your electrician will run a load calculation to determine whether 200A covers you or whether a 400A (often configured as two 200A panels sharing a 400A service entrance) is worth planning for now.

What drives your final number

Three variables account for most of the spread in Arizona panel upgrade pricing.

Which city you're in. Arizona has no statewide electrical code, so every municipality runs its own permitting office, sets its own permit fee schedule, and operates on its own inspection timeline. Phoenix's permit fees for a residential panel upgrade are typically $250–$400. Scottsdale runs higher — $400–$650 for the same scope — reflecting that city's more involved permit process. Tempe, Mesa, Chandler, and Gilbert each have their own schedules in a similar range. Your electrician will include the permit fee as a line item in the quote; it varies by address, not just by scope.

Service entrance and meter base condition. Arizona's housing stock skews newer than most of the country — a large proportion of the Phoenix metro was built after 1980, when 200-amp service was already standard. If your home was built in that era and has never had panel work, the service entrance and meter base are often in good condition and the upgrade is straightforward. Older homes in central Phoenix, Tempe, and Tucson built in the 1950s–1970s more frequently need meter base replacement or wiring upgrades to the incoming service alongside the panel swap, which adds $300–$800 to the base cost. Your electrician will assess this during the site walkthrough.

Outdoor vs. indoor panel location. Arizona panels are almost universally mounted on exterior walls — the climate makes outdoor mounting practical year-round, and there's rarely a complicated conduit run involved. Panel relocation — needed when an older panel is in an unusual spot or needs to move to meet current APS or SRP meter placement requirements — is the main variable that can add $1,500–$4,000 to a job.

APS, SRP, and TEP: utility coordination

Every panel replacement requires the utility to disconnect power at the meter before work begins and reconnect after the inspection clears. Your electrician handles both steps — you don't contact APS, SRP, or TEP directly.

APS (Arizona Public Service) covers most of the Phoenix metro west of the Valley: Phoenix, Glendale, Peoria, Surprise, Goodyear, Avondale, Buckeye, and parts of the northwest valley. APS's residential service change process is well-established: your electrician submits a service application, coordinates the meter pull timing, and schedules reconnection once the inspection has cleared. In the core Phoenix market, same-day or next-day reconnection after inspection is standard for routine 200-amp upgrades.

SRP (Salt River Project) serves the east valley: Mesa, Chandler, Tempe, Gilbert, most of Scottsdale, and parts of north Phoenix. SRP's coordination process works the same way — your electrician submits the service order, SRP disconnects on work day, and reconnects after inspection. SRP is generally reliable on same-day reconnection for residential panel upgrades once the inspection passes.

TEP (Tucson Electric Power) serves Tucson and the surrounding Pima County area. Smaller portions of southern Arizona are served by UniSource Energy Services. TEP's residential service change process mirrors APS and SRP: your electrician coordinates directly, and same-day reconnection after inspection is the norm.

Your electrician will schedule the full sequence — permit, utility disconnect, inspection, reconnection — and give you an expected timeline when they book the job. In most Phoenix metro cities that runs one day on-site and one to two weeks start to finish.

Permits and inspections

Every panel replacement in Arizona requires an electrical permit. Your electrician applies for it, coordinates the inspection, and adds the permit fee to your invoice. You don't interact with the permitting office.

Permit fees vary by city: $250–$400 in Phoenix, $400–$650 in Scottsdale, $200–$400 in Tucson. Turnaround is typically a few business days in major markets, with same-day or next-day inspection scheduling once the permit is issued.

Rebates and incentives in 2026

Arizona's rebate picture for panel upgrades is straightforward: one active program for income-qualifying homeowners, and no direct panel rebate for the general market.

Efficiency Arizona HEAR Program — available, income-qualified. Arizona's HEAR program, run by Efficiency Arizona, covers up to $4,000 toward a panel upgrade as a point-of-sale discount — no tax filing, the amount comes off your total at installation. Households below 80% of area median income qualify for full coverage; 80–150% AMI qualifies for 50%.

25C federal tax credit — expired. The 25C Energy Efficient Home Improvement Credit expired December 31, 2025. It is not available for 2026 installations.

APS and SRP rebates. Neither APS nor SRP offers a rebate for panel upgrades. APS ended its residential equipment rebate programs entirely on January 1, 2026 — there's no appliance rebate to stack alongside a panel upgrade for APS customers. SRP has no panel-specific rebate program either. If rebates are a factor in your decision, the Efficiency Arizona HEAR program above is the relevant option.

How to evaluate quotes

Get three written quotes. In Arizona, electrical contractor pricing varies more than most homeowners expect — partly because the Phoenix metro has contractors across a wide range of sizes and business models, and partly because scope items like meter base replacement, service entrance work, and surge protective devices are sometimes included and sometimes listed as add-ons. If one quote comes in noticeably lower, ask your electrician to walk through what's included — the difference is usually scope, not margin.

A complete quote for an Arizona panel upgrade should clearly state: the new panel amperage and brand, labor hours, the permit fee (or confirmation it's added at actual cost), utility service coordination (APS, SRP, or TEP), a whole-home surge protective device, and any grounding system or service entrance updates identified during the site walk. If a quote doesn't itemize these components, ask your electrician for a written breakdown.

One question worth raising upfront — particularly in older Phoenix-area homes built before 1980 — is what happens if the electrician finds aluminum branch wiring once work begins. Aluminum branch wiring was common in construction through the early 1970s and requires specific connector types at every outlet and fixture to pass inspection when a panel is replaced. A thorough electrician will flag any indication of aluminum branch wiring during the initial assessment; budget for that conversation if your home is from that era.

On licensing: in Arizona, electrical contractors are licensed through the Registrar of Contractors (ROC), not a separate electrical board. For residential panel work, your electrician holds an R-11 or CR-11 license from the ROC. Their license number is a normal thing to ask for in the first conversation.

For the full picture on what to ask before hiring, see the electrician hiring guide. For national cost benchmarks and a full breakdown of what drives panel upgrade pricing, the main cost guide has the detail. If you're still deciding between 200A and 400A service, the 100 vs 200 vs 400-amp comparison walks through the load calculation without the cost data. If an EV charger is part of the reason you're upgrading, the Arizona EV charger panel upgrade guide covers whether you actually need a full panel upgrade before you commit. For what the upgrade process looks like step by step — permits, utility coordination, and timeline — see the Arizona 200-amp upgrade guide.
