Contractor Insurance and Bonding Requirements in New Hampshire: What Coverage You Need
New Hampshire does not require statewide general contractor licensing, but electricians and plumbers must be licensed through the NH Office of Professional Licensure & Certification (OPLC). These professionals face strict insurance and bonding mandates—including minimum liability coverage tied to project value, mandatory surety bonds, workers’ compensation certificates for any employee, and specific endorsement requirements—to legally operate and bid on projects.
NH OPLC Licensing and Core Insurance Mandates
The NH Office of Professional Licensure & Certification (OPLC) requires all electricians and plumbers—whether sole proprietors or LLCs—to hold active state licenses before performing work. To obtain or renew an OPLC license, applicants must submit proof of general liability insurance with minimum limits: $100,000 per occurrence for projects under $50,000; $250,000 for projects between $50,000–$250,000; and $500,000 for projects exceeding $250,000. Unlike many states, NH does not mandate commercial auto or umbrella policies—but insurers often bundle them for risk mitigation. Additionally, all licensed contractors must carry a $10,000 license bond (also called a 'qualifying agent bond') filed directly with OPLC. This bond protects consumers from fraudulent or negligent acts—not project completion—and is separate from contract-specific performance bonds. Failure to maintain continuous coverage results in automatic license suspension. Contractors must also name the State of New Hampshire as an additional insured on their general liability policy when working on public projects, per RSA 330-A:17-a.
Surety Bonds: License Bond vs Performance Bond in NH
In New Hampshire, two distinct surety bonds apply to contractors: the $10,000 license bond required by OPLC for electricians and plumbers, and optional—but frequently mandated—performance and payment bonds for individual contracts. The license bond is non-project-specific, serves as a prerequisite for licensure, and remains active for the license term (biennial renewal). In contrast, performance bonds are contract-driven: NH law (RSA 447:16) requires them only for public works projects over $100,000, where the bond amount must equal 100% of the contract value. Private clients may also require performance bonds, especially for residential remodels exceeding $75,000. Payment bonds—often bundled with performance bonds—guarantee subcontractor and supplier payments. All NH surety bonds must be issued by carriers licensed in the state and filed with the appropriate authority: OPLC for license bonds, and the awarding public entity or private owner for contract bonds. Importantly, NH does not allow self-bonding or letters of credit in lieu of surety bonds—only A-rated or better sureties qualify per NH Insurance Department Bulletin 2022-03.
Workers’ Compensation and Additional Insured Endorsements
New Hampshire law (RSA 281-A:2) mandates workers’ compensation insurance for *any* employer who hires even one part-time or seasonal employee—including family members—unless formally exempted via the NH Department of Labor’s Form WC-1A (for sole proprietors with no employees). Contractors without coverage face fines up to $2,500 per violation and potential criminal penalties. Certificates of insurance must list the NH Department of Labor as certificate holder and include effective dates matching the license period. Regarding additional insured (AI) status, NH courts enforce AI endorsements strictly: blanket AI clauses are insufficient for public projects. Contractors must provide specific AI endorsements naming the project owner, general contractor, or the State of New Hampshire *by legal name and address*, with primary/non-contributory language and coverage extending to ongoing operations and completed operations. OPLC audits routinely reject certificates lacking these precise terms. For subcontractors, AI status must be verified *before* mobilization—NH RSA 447:19 prohibits payment release until valid AI documentation is submitted to the prime contractor or public agency.
General Liability Minimums by Project Size and Practical Compliance Tips
NH ties general liability minimums directly to project scope—not business revenue or number of employees. Projects under $50,000 require $100,000 per occurrence/$300,000 aggregate; $50,000–$250,000 projects require $250,000/$500,000; and projects over $250,000 demand $500,000/$1,000,000. These thresholds apply to the *total contract value*, including labor, materials, and overhead—not just the contractor’s fee. Crucially, NH allows ‘project-specific’ liability policies, but they must be bound *before work begins* and list the client as an additional insured. Many NH insurers offer modular GL policies that auto-adjust limits based on declared project values—a cost-effective option for small contractors juggling multiple jobs. Also note: NH does not require inland marine or tools coverage, but OPLC recommends it for mobile trades. Finally, always verify your insurer is licensed in NH (check NH Insurance Department’s Producer Database), and retain all COIs, bond filings, and endorsement copies for at least five years—OPLC may audit records during renewal or complaint investigations.

Do I need a license bond if I’m a sole proprietor electrician with no employees?
Yes. The $10,000 license bond is mandatory for all OPLC-licensed electricians and plumbers in NH—regardless of business structure or employee count. It’s a condition of licensure, not employment status, and must remain active for the full biennial license term.
Can I use my existing national insurance policy for NH projects, or do I need NH-specific coverage?
Your policy must be issued by an insurer licensed in New Hampshire and explicitly meet NH’s statutory limits and endorsement requirements. National policies often lack NH-specific AI language or correct bond filing protocols—verify with your carrier or use HandymenAI’s 'asesor-pyme' to audit compliance.
What happens if my general liability limit doesn’t match the project size threshold?
OPLC may suspend your license upon discovery, and public owners can reject bids or withhold payment. Private clients may terminate contracts for noncompliance. You must increase limits *before* starting work—retroactive coverage is invalid under NH Administrative Rule Env-E 202.05.
