How to write an underwriting summary that gets your submission quoted

An underwriting summary is a one-page narrative you send to a carrier alongside your ACORD forms. Its job is to tell the story of the risk — who the insured is, what they do, why they're a good account, and what you're asking for. Done well, it shortens the quoting timeline, reduces carrier follow-up, and positions your submission ahead of the stack.

Most agents either skip it entirely or write something so vague it adds nothing. This guide covers exactly what to include, how to format it, and the mistakes that slow everything down.

What is an underwriting summary?

An underwriting summary (sometimes called a cover letter or submission narrative) is a brief document — typically one page — that gives an underwriter context before they dig into the ACORD forms. It answers the questions an underwriter would ask if they called you: what does this business actually do, what's their loss history story, why are they shopping, and why should we write them?

It is not a replacement for the ACORD forms. It is a companion document that frames the risk so the underwriter already has a mental model before they open the application. A good underwriting summary turns a cold file into a warm one.

What to include in an underwriting summary

1. Business description (2–4 sentences)

Start with a clear, specific description of what the insured actually does. This is the most important section. Underwriters see hundreds of submissions that say "general contractor" or "consulting firm" — yours should say exactly what work they do, for whom, where, and at what scale.

Weak: "ABC Construction is a general contractor based in California."

Strong: "ABC Construction is a licensed general contractor specializing in commercial tenant improvement projects in the Los Angeles metro area. The majority of their work is for retail and office tenants in the $200K–$800K project range. They self-perform framing and drywall and subcontract electrical, plumbing, and mechanical. Annual revenue is approximately $4.2M."

2. Operations overview

Expand on the key exposure factors relevant to the lines you're quoting. For GL this means subcontractor use, work type, geographic scope, and products/completed operations. For property it means construction type, occupancy, and protection. For workers comp it means job classifications and payroll breakdown. Tailor this section to the specific coverages in the submission.

3. Loss history narrative

Numbers alone don't tell the full story. If the insured has losses, explain them. Context matters enormously to underwriters. A $45,000 GL claim looks very different depending on whether it was a one-time slip-and-fall at a client site five years ago with no recurrence, or a pattern of property damage claims across multiple projects.

If the insured is loss-free, say so explicitly — "Clean loss history across all lines for the past five years" — rather than leaving the underwriter to assume.

4. Prior insurance history

Note the current carrier, the reason for shopping, and any coverage changes being requested. If the insured is shopping due to a non-renewal, explain the circumstances. If they're looking for broader coverage than their current policy, explain why. Underwriters want to know the reason a risk is on their desk.

5. Coverage requested

Close with a clear list of what you're asking for: lines of coverage, limits, effective date, and any special endorsements or requirements. Make it easy for the underwriter to know exactly what quote you need without hunting through the ACORD forms.

Format and length

Keep it to one page — two at most for complex risks. Use short paragraphs or bullet points. Underwriters are reading dozens of submissions a day; dense blocks of text slow them down. Use a consistent format across all your submissions so carriers learn to find information quickly in your files.

A good structure looks like this:

• Header: insured name, effective date, lines requested, your contact info
• Business description paragraph
• Operations bullet points
• Loss history (one sentence if clean, a short paragraph if not)
• Prior carrier and reason for shopping
• Coverage requested with limits

Common mistakes that slow submissions down

• Vague business descriptions — "various construction projects" tells an underwriter nothing. Be specific about work type, scope, and customer base.
• Ignoring losses — skipping context on a loss history almost guarantees a callback. Address it proactively.
• No reason for shopping — underwriters wonder why the current carrier isn't renewing. Explain it or they'll assume the worst.
• Missing coverage specifications — saying "standard limits" isn't enough. State exactly what you need.
• Too long — a four-page narrative buries the key information. One page, well written, is more effective.

How to write them faster

The challenge with underwriting summaries is that every account is different, so you're writing from scratch each time. The information you need — business description, operations, loss context — is all captured during intake. The problem is that most agents collect intake information in a way that makes it hard to turn into a clean narrative quickly.

AgencyAssist captures all the information you need for an underwriting summary during the client intake process and automatically generates the narrative for you. By the time the client submits their intake form, you already have a draft underwriting summary waiting in your dashboard — tailored to their specific risk, ready to attach to the ACORD forms.
