What insurance does New Hampshire require of contractors?
#insurance- Regime
- none for chimney/GC work (no state GC/HIC credential; fuel gas fitter license for gas work)
- Liability minimum
- NONE for chimney/GC work — no state credential exists to attach it to; fuel gas fitter eligibility rules (Saf-Mec 300/305) contain no liability-insurance requirement found; whether the fuel gas fitting BUSINESS ENTITY license requires insurance is UNVERIFIED; TRAP: SEO/bond-vendor sites claim an 'RSA 332-B HIC registration with $10,000 bond' — FALSE, RSA 332-B is the NH Veterinary Practice Act (verified on gc.nh.gov); NH AG's position is contractors need no license
- Bond
- none at state level (the circulating '$10k NH HIC bond' is debunked — see liability column)
- Guaranty fund
- none — no guaranty/recovery fund of any kind
- Workers' comp threshold
- 1 employee (full or part-time) triggers coverage (RSA 281-A:5 per NH DOL FAQ); sole proprietors/partners/self-employed exempt for themselves, may elect in; corporations with only 3 corporate officers and no other employees exempt
- How to verify
- insurance: nothing to verify for chimney work; gas license lookup oplc.nh.gov/license-lookup (AUTOMATED); WC public lookup: NH DOL Workers' Compensation Insurance Coverage Verification (NCCI-fed, search by business name/FEIN, shows insurer + policy + effective date)

Before anyone goes on your roof
What should you ask a chimney company in New Hampshire?
- Is your company a member of the National Chimney Sweep Guild (NCSG)?
- Does the technician coming to my home hold an individual NCSG certification, and which one?
- Does the technician hold a National Fireplace Institute (NFI) certification — and for which fuel: wood, gas, or pellet?
- What other certifications does the technician hold (for example, CSIA), and can I check them on the issuer's own roster?
- What state or local license or registration covers this work here, and what is the number?
- Will you send a certificate of insurance, dated and naming your company, before work starts?
- Which NFPA 211 inspection level — Level 1, 2, or 3 — are you performing, and why that level?
- Will you show me what you found — photos or video of the flue — in writing?
We take no fee from any certification body, guild, or contractor, and are not paid to mention anyone named.
