Self-Insured Retention (SIR)

A self-insured retention (SIR) functions similarly to a deductible in that you pay a portion of each claim, but there are critical differences. With a deductible, the insurance carrier typically handles the claim from the start and then bills you for the deductible amount. With an SIR, you are responsible for managing and paying the claim yourself until the retention amount is exhausted — only then does the carrier step in.

For tree service companies, SIRs most commonly appear on umbrella or excess liability policies, and sometimes on E&S market GL policies. A $10,000 SIR means you handle and pay for every claim up to $10,000. If the claim exceeds that threshold, the carrier takes over. This structure gives you control over small claims (and keeps them off your loss history with the carrier) but requires you to have the financial resources and claims-handling capability to manage claims independently up to the SIR.

The key practical difference from a deductible: defense costs. Under most policies with a deductible, the carrier provides a defense attorney from the start, and the deductible applies only to the indemnity payment. Under many SIR structures, you are also responsible for defense costs within the SIR. Hiring an attorney to respond to a demand letter or defend a small lawsuit can quickly consume a $10,000 or $25,000 SIR before any settlement payment is made.

SIRs are a risk-financing tool best suited for larger tree service operations with strong cash reserves and the administrative capacity to handle small claims in-house. For smaller operations, a traditional deductible structure is usually more appropriate because the carrier handles claims administration from dollar one.
