Using insured subs is a no-brainer. If the sub can provide a currently valid certificate of insurance evidencing Workers’ Compensation, you won’t be charged on your own policy. I would say that about 90% of the subs used by our builder clients are insured subs. This is a much higher percentage than was the case 15 years ago. Also, you don’t want your loss record or experience modification ruined by taking a hit on a claim for an uninsured sub. If you protect your loss record by only doing business with insured subs, this will translate into savings in the long term with both a lower experience modification and more scheduled credits being applied to your policy.
