This guide will uncover insurance costs for Connecticut contractors across popular policies like general liability, workers’ compensation, bonds, equipment coverage, and more. We’ll explore the key variables impacting your premiums, provide benchmarking data for small, medium and large contractors, and suggest strategies to secure favorable rates. 

Understanding typical contractor insurance expenses in Connecticut allows you to evaluate policies suitable for your business. While your exact premiums depend on your unique attributes, this data offers helpful context to inform smart insurance decisions.

Connecticut contractors must have the appropriate insurance coverage to operate in the state. Contractor insurance policies typically include general liability insurance for contractors to protect against third-party claims and workers’ compensation coverage for contractors to cover employee injuries on the job.

Key Factors Influencing Insurance Costs for Contractors

Here are some key factors that can influence insurance costs for contractors:

Type of work – The type of contracting work being done (construction, plumbing, electrical, etc.) impacts risk and therefore insurance rates. Higher risk work typically has higher insurance premiums. Roofing, demolition, grading, and exterior work tend to have elevated risk.

Years in business – Contractors who are new to the business often pay higher premiums until they establish a track record over 3-5 years. Insurance companies view experience as an indicator of lower risk. New business policies may be required.

Claims history – Prior claims made by a contractor will often result in increased premiums, especially if the claims were frequent or costly. Too many claims can make a contractor uninsurable. A clean claims history helps lower rates.

Coverage limits – Higher levels of coverage for things like general liability or workers’ compensation mean higher premiums. Contractors must weigh the cost vs the amount of protection needed for their business. Minimum limits are required.

Number of employees – More employees on payroll increases the risk exposure for things like workers’ comp. Rates will be higher as a result. A minimum # of employees may be required for workers’ comp.

Safety record – Contractors with poor safety records or OSHA violations can expect to pay higher premiums. Proactive safety reduces risk. Experience Mods are used to measure safety.

Business size – Larger contracting firms often get better rates based on economies of scale and broader risk distribution. Smaller firms pay more.

Insurance provider – Rates can vary significantly between insurance companies. Competitive bidding is wise. AM Best ratings determine financial strength.

The key is to maintain excellent records, safety practices, qualifications, and choose appropriate coverages to help minimize insurance costs. Controlling risk lowers premiums.

$2.5 million$25,000 – $125,000

General liability policies commonly exclude coverage for pollution, asbestos, prior work, contractual liability, and professional services. Higher limits, lower deductibles, and expanded coverage increase premiums.

Key factors that influence general liability insurance costs for Connecticut contractors:

Type of work – Certain types of contracting work like roofing, plumbing, and electrical work are seen as higher risk and thus have higher premiums. More hazardous work leads to higher liability costs.

Revenues – Contractors with higher annual revenues have greater exposure and will generally pay more for liability coverage. Revenue is used as a proxy for business size and risk level.

Claims history – Contractors with past claims filed against them will see increased premiums, especially if claims were frequent or costly. Too many claims can mean no coverage.

Experience – Newer contractors are viewed as higher risk and will pay more until they establish a solid track record, usually at least 5 years in business. More experience means lower rates.

Risk transfer – Requiring subs to carry GL insurance and clients to sign liability waivers lowers the contractor’s liability risk and premiums.

Policy limits – Higher liability limits mean higher premiums, but lower limits may expose you to personal liability if claims exceed limits. Minimum $1M per occurrence limits are typical. 

Deductibles – Choosing a higher deductible, the amount you pay on a claim before insurance kicks in, can significantly reduce premiums.

Insurance company – Premiums can vary amongst insurers based on financial strength, service, and pricing. It pays to shop around.

$150,00010% – 20%
$500,0008% – 15%
$1 million6% – 12%
$2.5 million4% – 10%

At a 10% rate, a contractor with a $500,000 payroll would pay $50,000 annually for workers’ compensation insurance. Payroll, job type, claims history, company size, and other factors determine final rates.

Workers’ compensation policies have no deductibles. Coverage is compulsory for employers in CT. Exclusions may apply to owner family members, some subcontractors, and out of state employees.

Key factors that influence workers’ compensation insurance costs for Connecticut contractors:

Payroll – Payroll directly impacts premiums. Higher payroll equals higher premiums. Accurate payroll audits are performed.

Job classification – The type of work performed is classified by risk level. Carpentry has lower rates than roofing for example. Office work is lower risk than construction.

Experience rating – Your claims history results in an experience rating (mod factor) that can lower or raise premiums. High claims lead to higher rates.

Industry trends – Premium rates for the construction industry as a whole influence costs. Frequency and severity of claims impact rates.

Safety record – Good safety and low injury rates can qualify contractors for premium discounts. Poor safety leads to increased premiums.

Subcontractors – Using uninsured subcontractors increases premiums. Requiring subs to carry WC lowers contractor risk and costs. 

State laws – CT benefit levels, discounts, and other regulations impact local premiums and costs. State rate mandates affect pricing.

Deductibles – Higher deductibles lower WC premiums but increase your per claim costs. Often not advantageous due to high benefit levels. 

Insurance company – Premiums can vary based on insurer reputation, stability, service, and pricing. A financially strong carrier may offer lower pricing.
