General Contractor Business Interruption Insurance Cost

What rating basis does Business Interruption use for General Contractors?

Business Interruption for General Contractors is rated per $1,000 of insured income — that is the unit of exposure carriers use to scale premium against operations. The base rate per unit comes from ISO loss costs, refined by each carrier with its own experience.

Two adjustments do most of the work after the base rate: your experience modifier (which captures three years of paid claims relative to expected losses) and the schedule rating credits or debits an underwriter applies based on operational quality.

What kinds of claims do General Contractors actually file on Business Interruption?

Carriers do not price Business Interruption for General Contractors in the abstract — they price it against the loss patterns the specialty trade segment has produced over the last decade. The scenario set that drives most of the premium load includes the frequency-driven losses typical of this segment: claims that combine moderate-to-high frequency with severity tails that surprise less-experienced markets.

A single severe loss inside the prior three-year window typically lifts renewal premium 25-50% for the following cycle. Two or more inside the same window push the account toward surplus lines, where pricing is typically 1.5-3x standard market levels.

Low-end vs high-end profile: what does each look like?

The $780–$4,860/year spread on Business Interruption for General Contractors is not arbitrary. The low-end profile is structurally different from the high-end:

Low end — typically a general contractor with stable ownership, clean 3-year claims, fewer than 5 employees, conservative territory, and documentation that anticipates underwriter questions. Standard-market pricing.

High end — material claim history, larger operation, broader scope, or unusual exposures that push the carrier to either debit-price or move the account to surplus. Premium load of 1.5-3x the low-end norm is common.

Deductible math: should General Contractors raise their Business Interruption deductible?

Raising deductible is the most direct way for General Contractors to reduce Business Interruption premium without changing operations. The tradeoff: you self-insure the first dollars of every claim in exchange for a smaller annual premium.

Whether the math works depends on claim frequency. For specialty trade risks, expected claim count is the variable to model. If your three-year history shows zero claims, raising deductible is almost always net-positive economically. If you have one or more claims, the breakeven moves and a tax-advised modeling exercise is worth doing.

The Business Interruption submission package for General Contractors

To quote Business Interruption accurately on General Contractors, carriers typically require: ACORD 125 (commercial general application), ACORD 126 (general liability supplemental) where applicable, three years of loss runs, payroll details, revenue split by operation type, and a brief operations narrative.

Submissions that arrive complete are quoted in 1-3 business days. Submissions missing loss runs or payroll detail typically cycle for 5-10 days while the underwriter chases the missing information — and during that delay, the account often gets deprioritized vs cleaner submissions in the underwriter's queue.

Which carriers actually want to write Business Interruption for General Contractors?

Carrier appetite for General Contractors Business Interruption is narrower than most brokers assume. Of 50+ carriers writing commercial lines, typically only 6-10 actively pursue specialty trade risks, and the appetite shifts year to year based on each carrier's loss experience in the segment.

Targeting submissions to currently-hungry carriers makes a material difference. A submission sent to ten carriers including six that are pulling back from the segment produces six declines or high quotes that anchor the account expectation higher than necessary.

State-by-state factors that change General Contractors Business Interruption pricing

Where a general contractor operates affects Business Interruption pricing as much as how the general contractor operates. State-level factors include: rate filings approved or pending, judicial environment, NCCI vs independent rating bureau treatment, and state-specific endorsements required (or excluded) by law.

Coverage Axis sees the same specialty trade risk priced 25-45% apart between the cheapest and most expensive feasible states. The state your business is domiciled in vs the states you operate in both affect the rating math.
