Cheapest general contractor insurance — lowest carriers

The cheapest general contractor insurance in 2026 comes from Thimble for solo and 1–2 tech shops (annual GL premiums starting around $540), Next Insurance for 3–10 employee shops (starting around $1,800/year bundled with workers' comp and commercial auto), and Simply Business for shops with non-standard class codes or moderate claims history. Premium alone is a misleading decision criterion — a $200/year premium difference matters far less than claim-service quality, coverage exclusions, and whether the carrier will stand with you on a disputed claim. This guide breaks down the actual lowest-premium quotes by trade and shop size in 2026, then identifies the cheap options worth buying and the cheap options that are cheap for a reason.

The actual lowest premiums by trade (April 2026)

Premiums below are the lowest competitive quotes a shop with clean claim history ($1M/$2M GL, standard class codes, US-based operations) would see in April 2026. Quotes verified via Thimble, Next Insurance, Simply Business, and Hiscox online instant-quote tools.

Trade	Solo / 1-truck	5-tech shop	10-tech shop

Three patterns emerge:

Thimble is cheapest for solo shops under $250K revenue. Monthly billing, instant binding, no annual commitment.
Next Insurance is cheapest for 3–15 employee shops because of bundle discounts (10–15% savings on GL+WC+commercial auto).
Simply Business often beats Next for non-standard classes or claims-history issues because they aggregate across multiple carriers.
Traditional carriers (The Hartford, Travelers) run 10–20% more than online-first but with better claims support.

Who should buy the cheapest option

Solo contractors with no employees, under $150K revenue, no commercial customers yet. Thimble monthly or annual is the genuinely cheapest credible option. Binding in 10 minutes, certificates of insurance issued instantly. You give up very little at this scale.

1–3 tech shops with $150K–$500K revenue. Next Insurance online bundle. The 10–15% bundle discount on GL+WC+auto typically puts Next $400–$800/year cheaper than quoting each coverage separately.

Contractors in high-cost-of-insurance states (California, Florida, New York). Simply Business often aggregates to better rates than Next or Thimble in these states. Worth a 15-minute quote even if you have a Next quote in hand.

Contractors with modest claims history (one medium claim in last 3 years). Thimble and Next often decline or non-renew after a claim. Simply Business and Hiscox have more flexible underwriting at moderate premium costs.

Who should NOT buy the cheapest option

Shops with revenue over $1M annually. Online-first pricing gets uncompetitive at this scale. Agent-placed coverage from The Hartford, Travelers, or Chubb will run 5–15% higher but with meaningful differences: dedicated claims adjusters, loss-control consulting, higher-limit options, and custom endorsements that online-first can't handle.

Shops with employees doing specialty work. High-voltage electrical, roofing crews at height, HVAC work on hospital/data center critical systems — these need carriers with deeper coverage and more specialized underwriting. Thimble and Next often exclude or decline specialty classes.

Shops with any history of lawsuits or large claims. Cheap online-first carriers have strict underwriting. One significant claim usually results in non-renewal, forcing you into the assigned-risk market or expensive surplus-lines carriers. Build a relationship with a traditional carrier before you need claims service.

Shops with commercial customers requiring custom endorsements. Commercial customers sometimes ask for endorsements (manuscript forms, specific waiver language, project-specific coverage) that online-first carriers can't add. Work through a broker who can get these placed.

What you give up for cheap premiums

Claims service quality. The biggest trade-off. Online-first carriers handle simple claims fine but struggle with complex claims (multi-party lawsuits, construction-defect claims, long-tail completed-operations claims that surface years later). Traditional carriers assign dedicated adjusters who manage claims aggressively.

Policy flexibility. Thimble and Next offer standardized policies. Need a specific endorsement, higher limit for one project, or a manuscript form? You won't get it. Traditional agent-placed carriers handle these requests.

Financial stability in hard markets. Online-first carriers have shorter track records. In hard insurance markets (like 2021–2023), some online-first carriers non-renewed blocks of business or raised rates 30–50% at renewal. Traditional carriers in the contractor space have smoothed rate changes over longer periods.

Loss-control support. Traditional carriers assigned to contractors with $15K+ annual premium offer safety audits, training resources, and on-site loss-control consulting. Online-first carriers don't.

Umbrella coverage. Umbrella policies (excess liability above your GL and auto limits) are harder to place through online-first carriers. Most shops needing umbrella coverage route through an agent to stack carriers appropriately.

How to actually get the cheapest quote that's also good

For solo and 1–3 tech shops:

Get an online quote from Thimble (10 minutes)
Get an online quote from Next Insurance (15 minutes)
Compare premium + bundle savings + what's included
Read the policy exclusions carefully (especially completed operations, subcontractor coverage, specialty-trade exclusions)
Pick the better of the two. Not a lot of difference for most trades at this scale.

For 5–15 tech shops:

Get an online quote from Next Insurance (bundled GL+WC+auto)
Get an online quote from Simply Business (multiple-carrier panel)
Request a quote from Hiscox (online + phone follow-up)
Ask an independent agent for a quote shopping The Hartford and Travelers
Compare all four on premium, claim service ratings (check Trustpilot, BBB, J.D. Power), and policy exclusions
If premium spread is under 10%, pick based on claim service quality. If premium spread is over 20%, investigate why — it usually signals a class-code or underwriting issue worth addressing

For 15+ tech shops:

Work with an independent insurance broker who handles contractor accounts
Submit a complete application (3 years loss runs, payroll breakdown by class, subcontractor list, safety program documentation)
Broker shops 4–8 carriers in parallel
Compare premium, dividend-plan options, deductibles, loss-sensitive programs
Price alone shouldn't decide — claims handling and financial strength matter more at this scale

The "too cheap" red flags

A premium quote 30%+ below market signals something is off. Things to check:

Coverage exclusions you didn't know about. Does the policy exclude completed operations? Subcontractors? Specific trades? Common on cheap policies.

Low aggregate limits. A $1M per-occurrence / $1M aggregate policy looks cheap until one $900K claim eats most of your annual coverage. $1M/$2M is the practical minimum.

Non-admitted / surplus lines carriers. Some cheap quotes come from surplus-lines carriers that aren't regulated by your state insurance department and don't have state guaranty fund protection if they go insolvent. Verify the carrier is admitted in your state via your state insurance department website.

Weak financial ratings. Carriers rated below A- by AM Best are often cheaper but present real solvency risk. A bankruptcy takes your paid premium and your claim with it.

Hidden deductibles or coinsurance. Some cheap policies have $5K+ per-claim deductibles or coinsurance provisions (you pay a percentage of every claim). Read the declaration page.

Discount stacking — legitimate ways to lower premium

Before accepting the quote as-is, ask about:

Bundle discounts. Multiple policies (GL+WC+auto) with one carrier typically saves 10–15%.

Pay-in-full discount. Paying annual premium upfront saves 3–8% vs monthly installments.

Association / affinity discounts. Membership in industry associations (BNI, local HBA, PHCC for plumbing, ACCA for HVAC, NECA for electrical, NRCA for roofing) can unlock 5–15% discounts at several carriers.

Safety program credits. Documented safety programs, OSHA 10/30 training, and incident-reporting procedures earn 2–8% credits at most carriers.

Claims-free discounts. 3+ years with no claims typically earns 5–15% credit.

Electronic billing / paperless. Small discount (2–5%) for opting into electronic documents.

Higher deductibles. Accepting a $1K–$5K per-claim deductible on larger policies can save 8–20% on premium. Trade-off: you pay claim costs up to the deductible.

FAQ

Is Thimble or Next Insurance cheaper for contractors?

Thimble is almost always cheaper for solo contractors under $250K revenue. Next becomes competitive — and usually cheaper on bundles — for 3+ employee shops buying GL, workers' comp, and commercial auto together.

Can I buy the cheapest policy now and switch carriers later?

Yes. Most policies are annual and cancelable with 30-day notice (though some annual policies charge a short-rate cancellation fee of 10–25% of premium). Many contractors start cheap on Thimble then switch to a traditional carrier as they grow. Build a relationship with an independent agent early so you have options when you're ready.

Why is my contractor insurance so much more expensive than my neighbor's?

Five variables dominate contractor GL premium: trade class code (roofing is 10× HVAC service), annual revenue/payroll, state, claims history, and coverage limits. Two shops next door to each other can pay very different premiums for these reasons alone.

How often should I shop my insurance?

Every 2–3 years, or whenever you have a meaningful business change (hired employees, bought a commercial vehicle, expanded to a new state, added a new service line). Don't shop annually — carriers reward loyalty with lower renewal rate increases.

Can I get workers' comp cheaper than Next Insurance?

For shops with clean claim history and standard class codes, rarely. Next's online platform is priced aggressively on workers' comp. Shops with non-standard classes or claims history sometimes find better rates through an independent agent shopping Berkshire GUARD, AMTrust, or Employers.
