Certificates of insurance: what customers are really asking for

Additional insured, waiver of subrogation and primary and non-contributory, translated into what each one costs you.

Updated August 17, 2026 · 2 min read


A certificate of insurance is a one page summary proving coverage exists. It is not the policy and it grants nothing by itself. What matters is the endorsements behind the words on it.

The three requests you will see

Read the contract before you sign

The insurance requirements section is where the cost hides. A contract demanding five million dollars of auto liability, a waiver, additional insured status on a primary basis and thirty days notice of cancellation is asking for real money. Get the language to your agent during the bid, because after signing you are obligated whether or not it is affordable.

Notice of cancellation

Many contracts demand that the insurer notify the customer 30 days before cancellation. Most carriers will not agree to that language, and certificates now carry standard wording about it. If the customer insists, the fix is usually a negotiation rather than an endorsement.

Common follow-up questions

Does adding an additional insured raise my rate?

Usually a small charge, and some policies include blanket additional insured status when required by written contract, which is the cheapest way to satisfy it.

Can I just type the wording on the certificate?

No. If the endorsement is not on the policy, the certificate is inaccurate and the customer is not actually covered. That is a serious problem for both sides.

What is a blanket endorsement?

One endorsement that automatically grants additional insured or waiver status to anyone you have agreed in writing to include. It saves paperwork for businesses issuing many certificates.
