ERGO NEXT has the cheapest workers’ comp insurance for California construction businesses at $446 a month per employee, 40% below the $739 industry average, and it’s cheapest for all 45 construction trades we analyzed. biBERK is the runner-up at $637, $191 more a month per employee. For most contractors, the cheapest policy is also the practical pick. Roofing, concrete, HVAC, asbestos abatement and tree service contractors need coverage to keep their license, and buying online and downloading proof of coverage the same day can keep a crew from sitting idle. Subcontractors whose general contractor requires a waiver of subrogation can add a blanket waiver online, but ERGO NEXT doesn’t offer scheduled waivers, so if a project owner wants to be named on its own waiver, confirm a blanket waiver satisfies the contract before you buy. The table below shows the cheapest insurers for 15 common construction trades in California.

The Hartford has the cheapest workers’ comp insurance for California healthcare businesses at $87 a month per employee, 31% below the $126 industry average, and it’s cheapest for 43 of the 49 healthcare business types we analyzed. ERGO NEXT is next at $98 and is cheapest for the other six, including companion care, optometry and travel nurses. For most practices, the cheapest policy is also a strong pick, since The Hartford pairs its low rates with 24/7 claim reporting and help finding nearby doctors for injured staff. Companion care agencies are the exception, because ERGO NEXT is $9 a month cheaper per employee, but caregivers who work alone in clients’ homes may get more out of The Hartford’s around-the-clock claims help. The table below shows the cheapest insurers for 15 common healthcare business types in California.

ERGO NEXT has the cheapest workers’ comp insurance for California food and beverage businesses at $80 a month per employee, 26% below the $108 industry average, and it’s cheapest for 24 of the 26 food and beverage business types we analyzed. The Hartford is next at $95. For most restaurants and food businesses, the cheapest policy is also a strong pick, since ERGO NEXT’s pay-as-you-go billing connects to payroll providers like Square and Gusto, so your premium follows the part-time and seasonal staff you add and lose. Coffee shops are the closest call, because biBERK is cheapest by about $1 a month per employee, a gap small enough that ERGO NEXT’s higher-rated customer service can be worth it. The table below shows the cheapest insurers for 15 common food and beverage businesses in California.

ERGO NEXT’s billing connects to payroll providers like Square, which helps stores that add staff for the holidays, while The Hartford’s 24/7 claims help matters more for e-commerce businesses with warehouse staff, where rates run highest. The table below shows the cheapest insurers for 15 common retail businesses in California.

For most cleaners, the cheapest policy is also a strong pick, since ERGO NEXT lets you download a certificate of insurance in minutes when an office or property manager asks for proof of coverage before your team starts. Garbage collection is the exception, because it’s the most expensive cleaning service at $516 a month per employee with The Hartford, which is cheapest there and also offers 24/7 claim reporting. The table below shows the cheapest insurers for all 15 cleaning business types in California.

ERGO NEXT has the cheapest workers’ comp insurance for California transportation businesses at $556 a month per employee, 29% below the $784 industry average, and it’s cheapest for all 17 transportation business types we analyzed. biBERK is next at $681. Transportation is the most expensive industry for workers’ comp in California, and for most businesses the cheapest policy is also a strong pick, since ERGO NEXT pairs the lowest rates with the highest-rated customer service of the insurers we compared. If you’d rather insure your drivers and your vehicles with one company, compare biBERK, which costs $125 more a month per employee but sells commercial auto in California, while ERGO NEXT sends auto to its partner Progressive. The table below shows the cheapest insurers for 15 common transportation businesses in California.

California uses an open-rating system, meaning insurers set their own workers' compensation rates rather than charging a uniform state-mandated price. Compare quotes from at least three insurers using the same payroll, employee classifications and coverage details. As an example, Asbestos contractors can save an extra $324/mo per employee in our data if they compared rates with ERGO NEXT and biBerk (the runner-up cheapest insurer). You can also use the California Department of Insurance's rate comparison tool to identify insurers with competitive base rates for your industry.

California's Workers' Compensation Insurance Rating Bureau (WCIRB) assigns classifications that affect your insurance rates. For example, roofing employees earning less than $33 per hour fall under code 5552, while those earning at least $33 per hour qualify for code 5553, which generally has lower rates. Verify employee classifications and maintain wage records, especially if you operate in construction, where California uses separate classifications for several trades based on hourly pay.

California businesses qualify for an experience modification rating (X-Mod) when their expected losses over the applicable experience period reach at least $11,700 under the rules effective September 1, 2026. Eligibility depends on payroll and industry risk, not a fixed employee count, so many smaller businesses won't qualify. If your business does, maintaining an X-Mod below 100% through workplace safety, fewer claims and effective return-to-work programs can reduce premiums. Review your WCIRB experience rating worksheet for reporting errors to ensure you don't overpay.

Workers' compensation premiums in California are calculated in part based on payroll, with insurers conducting audits to determine the final amount owed. Update your insurer when staffing or payroll changes substantially, maintain payroll records by classification and review audit results for errors. Accurate reporting helps prevent overcharges and unexpected premium adjustments.

California insurers may offer additional savings through schedule-rating programs that recognize favorable workplace risks and safety practices. For example, California's State Compensation Insurance Fund evaluates employers' Injury and Illness Prevention Programs (IIPPs), employee training, equipment maintenance and return-to-work procedures when determining schedule-rating adjustments. Ask insurers which practices qualify for credits and whether your business meets their eligibility standards.

California's State Compensation Insurance Fund operates as a competitive insurer and the state's insurer of last resort for employers unable to obtain private workers' compensation coverage. If private insurers decline your business or offer unaffordable rates, request a State Fund quote as an alternative. The State Fund isn't guaranteed to be cheaper, but it offers an alternative pricing option and access to coverage for businesses with difficult-to-insure operations.
