1
Gather your policy documents before you start
Locate your insurance policy, confirm the exact policy number, the insurer's claims department mailing address and email, and any notice deadline stated in the policy.
π‘ Many policies require notice within 30, 60, or 90 days of the loss β check this before anything else, as a missed deadline can void your right to claim.
2
Fill in the header, date, and subject line
Enter today's date, the insurer's claims department address, and your policy number in the subject line. Use the format 'Re: Notice of Insurance Claim β Policy No. [NUMBER] β Date of Loss: [DATE]'.
π‘ If you have a dedicated claims contact from a prior interaction, address the letter to them by name rather than 'Claims Department.'
3
Confirm policyholder details match the policy exactly
Use the legal entity name and address exactly as they appear on your policy declarations page. Note a separate operating or trading name in parentheses if needed.
π‘ Pull up your declarations page side-by-side while completing this section to catch any discrepancies before you send.
4
Write a factual, chronological description of the loss
Describe the incident in the order it happened β date, time, location, what occurred, and how the damage was discovered. Use plain factual language and avoid speculation about causes.
π‘ A two- to four-sentence description is sufficient for the initial notice. Save the detailed narrative for the proof-of-loss form submitted later.
5
Itemize the estimated damages by category
List each category of loss with a preliminary dollar estimate and label the total clearly as an estimate. Include categories even if the dollar amount is still unknown β mark those as 'TBD pending assessment.'
π‘ Contact a contractor, IT vendor, or equipment supplier for a quick verbal quote before sending β it gives the insurer a workable starting figure.
6
Attach or list your supporting documentation
Include photographs, a police or incident report number, any third-party repair estimates, and a brief inventory of damaged items. List everything you are enclosing in the letter body.
π‘ Send documentation as PDF attachments if submitting by email β compressed image files in a ZIP are frequently blocked by corporate mail filters.
7
Review the reservation-of-rights clause and send
Confirm the reservation-of-rights paragraph is present, verify the contact details in the signature block, and send by a method that creates a delivery record β certified mail, registered post, or email with read-receipt.
π‘ Keep a timestamped copy of the sent letter and any delivery confirmation in a dedicated claims folder β you may need to prove timely notice if coverage is disputed.
