How to request loss runs from Markel.
Markel documents different mPortal paths for workers' compensation and other policies, plus a request form. It also publishes release restrictions, so confirm the requester role before promising a prospect you can retrieve the report.
Documented report route
How to request
Agent portal
Workers' compensation: in mPortal, use Loss Runs under Quick Links and enter the end date and policy number. Other policies: open the account, go to Account Summary, then View Loss Runs. These paths are described on Markel's loss-runs page.
Online form
Markel's form asks for the policy or account number, insured, policy years, delivery preference and contact details. Its page restricts release to authorized policyholder/producer roles and states other-party release requires a broker-of-record letter. Confirm the applicable role with Markel before submitting.
Prepare your request
Use these details to organize the request, then follow the carrier's required fields and release process.
- The requested end date, WC versus other coverage, and the requester's confirmed AOR/BOR status
- Named insured and policy numbers copied exactly from the policy documents
- The exact policy periods and report valuation date requested by the receiving underwriter
- Your agency contact details and the permitted delivery recipient, confirmed with the carrier
- Any release or authorization documents the carrier specifically requires for your requester role

Common questions
Is an ordinary authorization letter enough?
Markel's page specifically refers to a broker-of-record letter and AOR/BOR restrictions. Do not assume a generic authorization letter satisfies that rule; confirm with Markel.
Which report end date should I enter?
Use the valuation date the receiving underwriter needs. Keep the selected end date with the downloaded report so your team can tell when the claims were valued.
