What the injury record means for the premium
With 1.9 cases per 100 workers the workers' compensation base rate for this class is comparatively modest, and only 79 percent of cases involved days away, restriction or transfer. Where the premium goes instead is liability: property damage and injury on client premises is the core exposure; every gc and most licences require a certificate, and that is a general-liability and professional-liability question rather than a payroll one. Expect the certificate requirements in your contracts to matter more than your loss history.
The nearest trades by injury rate are nonresidential building construction (1.9), automotive repair and maintenance (1.9), child care services (1.9); the same payroll insured in those classes would start from a similar workers' comp base.
