General Liability Insurance Cost for Contractors (2026)
Contractors pay three to five times more than office-based businesses for the same GL limits because of on-site physical work, third-party property exposure, and subcontractor oversight. Sub-trade matters more than carrier brand.
Cost by sub-trade
Carrier rating manuals split "contractor" into dozens of class codes. The eight below cover the residential and light-commercial trades that drive most retail GL inquiries. Each range assumes one to five employees, $250K to $750K revenue, $1M / $2M limits, and a clean three-year claims record. Heavier crews, higher revenue, or multi-state work all push you toward the upper end.
| Sub-trade | Annual range | Monthly range | Risk band | Typical limit required |
|---|---|---|---|---|
| General contractor | $1,200 - $4,500 | $100 - $375 | High | $1M / $2M |
| Roofing contractor | $2,000 - $6,000 | $167 - $500 | Very High | $1M / $2M, often $2M / $4M |
| Electrician | $900 - $2,500 | $75 - $208 | Medium-High | $1M / $2M |
| Plumber | $1,000 - $2,800 | $83 - $233 | Medium-High | $1M / $2M |
| Painter | $500 - $1,200 | $42 - $100 | Medium | $1M / $2M |
| HVAC contractor | $1,200 - $3,200 | $100 - $267 | Medium-High | $1M / $2M |
| Concrete / masonry | $1,400 - $3,800 | $117 - $317 | High | $1M / $2M |
| Drywall / framing | $1,000 - $2,400 | $83 - $200 | Medium-High | $1M / $2M |
Why contractors pay more
General liability is priced on third-party exposure. Three structural features of contracting work compound that exposure compared to office or retail trades. Each is worth a paragraph because each shows up directly in the rating.
On-site, customer-adjacent work
Contractors operate inside or alongside customer property. A dropped tool that damages a hardwood floor, a ladder strike that cracks a window, a stray nail that hits a parked car. These are routine GL claim scenarios. Carriers price the frequency, and frequency is high.
Property damage severity
When a contractor causes damage, the dollar value tends to be high. A roofing leak that reaches a finished basement easily clears $50,000. A burst water line during a plumbing renovation can run six figures. The per-occurrence limit of $1M exists because losses of this size occur every year.
Subcontractor oversight
Anything your subs do can become your problem. If a sub causes injury or damage, the property owner and their insurer typically come after you first. Carriers want to see that you collect certificates of insurance from every sub and that those subs name you as an additional insured. Sites that document this rigorously qualify for better pricing.
COI requirements for contractors
A certificate of insurance (COI) is the one-page proof of coverage that GCs, project owners, and municipalities require before you can begin work. The certificate itself is free; what it requires is an active GL policy with the right limits and the right additional insured endorsements.
| Project type | Per-occurrence | Aggregate | Umbrella often required |
|---|---|---|---|
| Residential remodel (under $250K) | $1M | $2M | Rare |
| Residential new build | $1M | $2M | $1M to $2M |
| Light commercial (under $1M project) | $1M | $2M | $2M |
| Mid commercial ($1M to $10M) | $2M | $4M | $5M |
| Public / school / municipal | $2M | $4M | $10M |
Other coverages contractors need
GL alone does not protect you against your own injuries, your tools, your trucks, or claims that your professional judgement was wrong. The four common adjacent coverages and rough cost ranges:
| Coverage | What it covers | Typical small-contractor cost |
|---|---|---|
| Workers compensation | Employee injuries and lost wages | $0.75 to $7.50 per $100 of payroll, varies sharply by state and trade |
| Commercial auto | Trucks, vans, and on-the-clock driving | $1,200 to $2,400 per vehicle per year |
| Inland marine (tools) | Tools and equipment in transit or at job sites | $200 to $800 per year for $25K of tools |
| Excess / umbrella | Layer above GL, auto, and employer liability | $500 to $1,500 per million in extra limits |
How to lower contractor GL premium
Five strategies tend to produce the largest savings for established contractors. None of them involve cutting coverage or moving to a non-admitted carrier.
- Document a written safety programme and a regular toolbox-talk schedule. Carriers commonly knock 5 to 10 percent off renewals with a credible safety file.
- Raise your deductible to $1,000 or $2,500 if cash flow allows; this typically cuts premium 8 to 15 percent.
- Verify every sub carries their own GL and names you as additional insured. Carriers inspect this at audit and surcharge for uninsured subs.
- Bundle GL with workers comp and commercial auto if your carrier writes a contractor package; multi-line discounts run 10 to 20 percent.
- Confirm your class code matches the work you actually do. A handyman classified as a general contractor pays significantly more for no additional protection.
