Underwriting Levers: What Insurers Look for and How to Improve Your Risk Profile Quickly

Commercial insurance is priced on the insurer’s expectation of future loss. Underwriters translate hundreds of data points—COPE for property, claims history, controls, and operational practices—into a single decision: price, terms, and whether they will offer coverage at all. This guide shows exactly what underwriters look for across major commercial lines, which levers you can pull fast to lower your premiums, and a 30/60/90‑day playbook that produces the strongest underwriting outcomes in the shortest time. Wherever possible the guidance is tied to U.S. industry standards and market evidence so you can act with confidence. (usi.com)

Quick summary — what this guide gives you

  • The top underwriting signals carriers read first and why they matter. (usi.com)
  • Line-by-line levers (Property, General Liability, Workers’ Comp, Commercial Auto, Cyber, Professional Liability). (www1.wsrb.com)
  • A prioritized, low-cost 30/60/90 plan you can implement immediately to show underwriting improvement.
  • Negotiation and documentation templates underwriters want to see (loss runs, safety scorecards, cyber attestations). (vouch.us)
  • Comparative decision table: time, cost, and expected premium impact for each lever.

Refer to these business-insurance essentials for related tactics and cost tradeoffs:

Part 1 — What underwriters look for (the universal signals)

Underwriters combine quantitative inputs (loss history, payroll, revenues, industry classification) with qualitative ones (safety culture, third‑party contracts, governance). Here are the most universal signals that shift pricing and capacity quickly:

  • COPE (Construction, Occupancy, Protection, Exposure) for property: construction type, occupancy and contents, fire protection and distance to hydrants/fire department, and external exposures (flood, wildfire, neighboring hazards). COPE is still the backbone of property underwriting. (usi.com)
  • Claims history (loss runs): frequency, severity, and trends over the prior 3–5 years. Underwriters treat loss runs as the single most predictive indicator of future loss and will often refuse to quote without them. (vouch.us)
  • Experience Modification Rate (EMR / mod) for Workers’ Comp: a calculated multiplier reflecting prior WC losses relative to peers; it directly scales premium. Recent NCCI plan updates and state split-point changes changed how mods are calculated and can move premiums for some employers. (ncci.com)
  • Controls and documentation: proof of safety programs, driver hiring and MVR review, preventive maintenance, cybersecurity controls (MFA, EDR, tested backups). Underwriters discount risks with verifiable, documented controls. (markel.com)
  • Financial and operational stability: revenue, payroll, years in business, contractor/vendor prequalification, and whether clients require insurance certificates. These affect both pricing and appetite.
  • Concentrations & contractual exposures: large single-client dependency, high-value subcontracting, and indemnity/hold‑harmless contracts (lower appetite or higher terms).

These signals are used differently per line—next we break down line-by-line factors and the fastest levers to improve them.

Part 2 — Line-by-line underwriting levers and how to implement them fast

Below are the top levers for each major commercial line, with practical steps you can take in days to months and examples of typical underwriting outcomes.

A. Commercial Property (Buildings, Contents, Business Interruption)

What underwriters check fast: COPE (construction, occupancy, protection, exposure), property valuations, maintenance records, prior claims related to water, fire, or wind.

Fast levers (high impact, often immediate):

  • Install or certify sprinkler/alarm systems; add monitored central station alarms for burglary. Many carriers price sprinklered properties more attractively or extend higher limits. Even retroactive inspection certificates and photos can produce immediate premium credits at renewal. (usi.com)
  • Document recent capital improvements and maintenance: new roof, electrical upgrades, HVAC service records. Underwriters reduce depreciation/age penalties when recent work is documented. (compstak.com)
  • Reduce contents exposure: move high-value stock to secure locations, schedule listed equipment, or reduce business interruption exposure by reconfiguring operations.
  • Improve public protection profile: gather ISO Public Protection Class (PPC) data and records of hydrant inspection/flow tests for submission. Underwriters use PPC to calculate fire-protection credits. (www1.wsrb.com)

Example outcome: adding a monitored alarm + documented roof replacement can move your building into a better rating tier and reduce property rate by several percentage points at renewal (varies by state/insurer). (wintersoliver.com)

B. General Liability (GL) & Products/Completed Ops

What underwriters check: operations and activities (what you do), contracts and indemnity obligations, claims history (esp. bodily injury and third‑party suits), training, and client contract obligations.

Fast levers:

  • Tighten vendor/contract wording and limit indemnities: adopt a standard insurance rider and insist on limits for subcontractor indemnity. Underwriters react positively to reduced downstream exposure.
  • Implement documented safety and incident investigation processes (e.g., toolbox talks, written SOPs). Provide proof (photos, sign‑in sheets) in submission.
  • Clean up historical claims narrative: supply concise explanations for each loss on the loss run that include cause, corrective actions, and whether the risk is remediated. A transparent, remediated loss history can avoid penalty loadings. (vouch.us)

C. Workers’ Compensation (WC)

What underwriters/check raters use: payroll, class codes, EMR (experience mod), claims frequency/severity, return‑to‑work programs.

Fast levers:

  • Reinforce return‑to‑work (RTW) and light-duty programs: insurers favor formal RTW programs because they reduce indemnity duration and reserve buildup—this directly lowers your mod over time.
  • Safety focus where most claims happen: implement targeted training for top claim drivers (e.g., lifting ergonomics, ladder & fall protection) and document the training completion. OSHA’s Safety Pays tools and OSHA consultation programs can help quantify ROI and support bargaining for premium credits. (osha.gov)
  • Audit payroll and classification accuracy: misclassified payroll can produce surprise audit adjustments that raise effective premium—correcting class codes can reduce cost immediately at audit.
  • Manage medical-only claims aggressively: frequent small claims drive EMR; focusing on early intervention lowers mod faster. NCCI updates to experience rating methodology can change employer-level mods—so stay current. (ncci.com)

Example: a targeted ergonomic program and RTW plan can reduce WC claims frequency and push an EMR from 1.15 to <1.00 over 12–24 months in many trades; carriers then offer lower renewal pricing and dividend eligibility. (safetyproresources.com)

D. Commercial Auto (fleets, delivery, employee drivers)

What matters: driver hiring standards, MVRs, telematics/dashcams, maintenance records, vehicle age/mileage, FMCSA compliance if trucking.

Fast levers:

  • Implement standard driver hiring checklist + MVR review and document policy enforcement (no hire for >1 at-fault crash last 3 years, no DUI). This is one of the fastest ways to reduce rate for small fleets. (markel.com)
  • Add telematics and dashcams (forward-facing & event-triggered). Many insurers offer immediate mid-term credits or re-rating if safe telematics scores are supplied; telematics also reduces claim severity through objective evidence. (ims.tech)
  • Enforce vehicle maintenance logs and periodic roadside inspections; provide records at submission to demonstrate fleet hygiene.
  • Train drivers on distraction and fatigue policies and document completions—this reduces frequency and is meaningful to underwriters. (arrowheadgrp.com)

Example: fleets that deploy telematics and coaching often show a 10–30% reduction in collision frequency within the first year, producing measurable premium savings or lower retention at renewal. (ims.tech)

E. Cyber Liability

What underwriters check: MFA, EDR/antivirus, tested backups (immutable/offline), patch management, vendor risk, incident response plans, prior incidents.

Fast levers (very high leverage now):

  • Enforce Multi‑Factor Authentication (MFA) on email, admin, VPN and critical SaaS. MFA is a near‑universal underwriting expectation and often a threshold for quoting. (makitsol.com)
  • Deploy Endpoint Detection & Response (EDR) on all endpoints and collect deployment screenshots or vendor attestations for submission. EDR + MFA together materially improves insurability. (provenit.com)
  • Establish and test backups and restore procedures (documented RTO/RPO and recent restore test). Insurers favor immutable or offline backups; lack of tested backups is a common declination cause. (provenit.com)
  • Create an incident response plan and schedule a tabletop exercise; provide the plan and dated exercise notes with submissions. Carriers frequently give pre-breach services and credits for tested IR plans. (govinfo.gov)

Example: in 2024–2025, many carriers made MFA + EDR + tested backups minimums for standard cyber forms; firms lacking these controls face declinations or carve-outs for ransomware. Adding these controls quickly opens access to competitive markets and better pricing. (makitsol.com)

Part 3 — The underwriting pack: what carriers want with your submission (speed wins)

Underwriters are overloaded. A clean, concise submission that answers primary questions reduces time-to-bind and avoids conservative surcharges.

Essential documents and data (submit these together):

  • Currently valued loss runs (3–5 years; include notes on each loss explaining remediation). Make this the first attachment. (vouch.us)
  • COPE summary for each location: year built, roof age, sprinkler/alarm status, occupancy description, photos. (www1.wsrb.com)
  • Drivers: MVR summary, hiring date, years’ experience, training completion. (westfieldinsurance.com)
  • Workers’ comp: EMR explanation, RTW policy, light-duty job descriptions, safety meeting logs. (ncci.com)
  • Cyber: MFA screencaps, EDR console export, backup architecture & test logs, IRP and tabletop notes. (provenit.com)
  • Contracts: sample AIA/ISO subcontractor indemnity language or client contract that shifts risk (highlight onerous clauses).
  • Recent financials and years in business (for professional liability & higher-limit accounts).

Deliver these in a single PDF bundle labeled “Underwriting Pack — [Company, Expiry Date]” to reduce back-and-forth.

Part 4 — 30 / 60 / 90 day action plan (prioritized, with expected impact)

The following schedule focuses on low-cost, high-visibility items underwriters reward:

0–30 days (quick wins; minimal cost)

  • Pull currently valued loss runs from all carriers (ask for 5 years). Review and add a 2‑line remediation note per claim. (Impact: immediate underwriter confidence; reduces surcharge risk.) (vouch.us)
  • Add MFA to admin/office email and VPN; capture screenshots and export policy enforcement logs. (Impact: unlocks cyber markets; often required to obtain standard cyber forms.) (makitsol.com)
  • Create a one‑page safety scorecard summarizing TRIR/DART, training hours, RTW program, and top 3 corrective actions. Share with your broker. (Impact: immediate underwriting favorability.) (osha.gov)

31–60 days (moderate effort; measurable change)

  • Deploy basic telematics/dashcams to high‑risk vehicles and begin coaching program. Start collecting driver scorecards. (Impact: rapid reduction in auto frequency; mid-term re-rating possible.) (ims.tech)
  • Schedule and document a backup restore test (capture logs and RTO/RPO). Add to the cyber pack. (Impact: improves cyber insurability and limit eligibility.) (provenit.com)
  • Correct any misclassified payroll/class codes before renewal audit. (Impact: eliminates surprise premium increases.)

61–90 days (projects with sustained ROI)

  • Complete a formal RTW pilot and document outcomes (days away reduced, medical claim durations shortened). Submit RTW outcomes to WC underwriter. (Impact: EMR reduction over 12–24 months.) (ncci.com)
  • Install or certify sprinkler/alarm systems (or obtain third-party inspection and photo proof). (Impact: property tier improvements at renewal.) (usi.com)
  • Run a tabletop cyber incident exercise and capture minutes/corrective actions. (Impact: reduces sublimits or exclusions, increases available capacity.) (govinfo.gov)

Part 5 — Negotiation checklist for renewal or shopping

When you have multiple quotes, use this checklist to extract premium and terms improvements:

  • Submit the full underwriting pack (loss runs + remediation) to every quoting carrier. No loss runs = conservative loading. (vouch.us)
  • Ask for quantifiable credits: telematics score cred, sprinkler credit, RTW credit, group dividend history, pay‑in‑full discount. Carriers have standard credits—ask for the numeric percent and documentation requirement. (ims.tech)
  • Use bundling (BOP + Auto + WC) where offered—compare bundled pricing vs stand‑alone; bundling frequently reduces administrative loads and generates multi-policy credits. See Bundle & Save: How Combining Policies (BOP + Auto + Workers’ Comp) Cuts Total Cost.
  • Leverage competing appetite and offer carriers the right to match better terms in writing (get a "best & final" boxed offer).
  • Negotiate audit timeframes and classification audits up front—reduce chance of large mid-term premium increases.

Part 6 — Quick reference table: levers, cost, time to implement, and expected premium impact

Lever Typical cost range Time to implement Lines impacted Typical premium impact (U.S., indicative)
Add MFA (email/admin) + screenshots $0–$5/user (tools vary) 1–7 days Cyber Unlocks standard cyber markets; avoids declination (0–30% on cyber premium) (makitsol.com)
Install monitored alarm $1,000–$5,000+ 14–45 days Property, GL 5–15% property rate improvement in many cases (usi.com)
Telematics + coaching $100–$400/vehicle + coaching 7–30 days Commercial Auto 10–30% reduction in collision frequency; rate improvement upon renewal. (ims.tech)
Sprinkler system certification $0–$XXX (if existing) / installation higher 7–120 days Property Can move to sprinkler credits: single-digit to double-digit % reductions. (www1.wsrb.com)
Return-to-work program + documentation Low (policy & admin) 30–90 days Workers’ Comp EMR improvements over 12–24 months; can reduce WC premium materially (varies by claims) (ncci.com)
Loss run clean-up & explanation pack Low (internal time) 3–14 days All lines Improves quoting outcomes; avoids default loading or declination. (vouch.us)
Tested backups & restore proof $0–$5,000 (varies by infra) 7–60 days Cyber Improves capacity and reduces ransomware sublimits; may reduce premium 10–30% or avoid carve-outs. (provenit.com)

Notes: expected premium impact varies heavily by industry, state, and carrier underwriting appetite. Use this table as a directional guide; combine levers for compounding effect.

Part 7 — Advanced tactics (when the market is tight)

  • Retrospective rating / large deductible programs: for mature loss-control operations, consider retrospective premium or large deductibles to lower base premium and align incentives—suitable for firms with solid cash reserves and claims management.
  • Captives and group self-insurance: for larger employers with predictable loss profiles, pooling risks can lower long-term costs but requires governance and capital.
  • Safety group / dividend programs: join an insurer or association safety group to access group dividends for low loss experience. Many trades have trade-association programs that accelerate premium recovery. (apps.oregon.gov)
  • Data-driven underwriting: implement telemetry and EDR logging and provide carrier-acceptable data extracts to enable behavior-based pricing (especially useful for fleets and tech companies). InsurTech platforms increasingly accept telemetry attestations to speed pricing. (insurnest.com)

Real-world example (composite, illustrative)

Company: Mid‑sized regional plumbing contractor — $3M revenue, 30 employees, 12 light trucks, property + GL + WC + Auto.

Baseline issues: EMR 1.15, 3 small WC claims in 3 years, few documented safety meetings, no telematics, property roof 12 years old.

Action plan (90 days):

  • Day 0: Pull 5-year currently valued loss runs and add remediation notes for each claim. (vouch.us)
  • 0–30 days: Begin telematics trial on 4 highest-risk trucks; implement mandatory MFA for admin email; deliver safety huddles + sign-in logs. (ims.tech)
  • 31–60 days: Launch RTW pilot; conduct backup restore test (for office data) and produce cyber pack; obtain roof inspection and schedule repair quotes. (ncci.com)
  • 61–90 days: Submit consolidated underwriting pack to three carriers; negotiate telematics and safety credits; opt for a slightly higher WC deductible to smooth cost.

Result (illustrative): within 12 months, EMR drops toward 1.00, telematics produces a measurable drop in collision frequency, and the insurer offers a 10–18% total premium reduction at renewal across Auto + WC + GL due to combined controls and documentation. (Results depend on carrier and state.) (ims.tech)

Mistakes that cost you money (and how to avoid them)

  • Waiting until the final 2 weeks before renewal to collect loss runs—this disables competitive quoting. Pull loss runs 60–120 days before renewal. (legalclarity.org)
  • Providing unverifiable statements (e.g., “we use MFA” with no proof). Always capture screenshots, policy exports, or vendor attestations for submission. (provenit.com)
  • Ignoring small recurring losses—they compound EMR and underwriter suspicion; investigate and fix root causes. (vouch.us)
  • Overlooking audit payroll/class code accuracy—classification errors lead to surprise bills. Audit proactively.

Checklist: documents & metrics to have on hand when shopping (top of broker’s request list)

  • 5-year currently valued loss runs (GL, WC, Auto, Property). (vouch.us)
  • COPE/location summary, photos, and proof of protection systems. (www1.wsrb.com)
  • EMR (experience mod) explanation & payroll split by class. (ncci.com)
  • Driver MVR summary and telematics score exports (if available). (westfieldinsurance.com)
  • Cyber screenshots (MFA logs, EDR deployment report, backup test proof, IR plan). (provenit.com)
  • Sample contracts/agreements with indemnity wording highlighted.

If you prepare this packet in advance, you shorten underwriting time, increase competitive options, and avoid conservative “rush” pricing.

Final notes and recommended next steps (for immediate ROI)

  1. Pull loss runs today (or instruct your broker) — this is the single fastest gating item for shopping and negotiating. (vouch.us)
  2. Add MFA and capture proof (screenshots, policy enforcement) — critical for cyber eligibility. (makitsol.com)
  3. Create a one‑page underwriting pack and safety scorecard for your broker to send with every quote. (Make it part of your renewal playbook.) (www1.wsrb.com)
