Excess liability insurance

Excess liability insurance provides additional coverage limits in excess of your underlying liability policy.

What does excess liability insurance cover?

An excess liability insurance policy, also known as excess liability coverage, offers financial protection and higher policy limits if a claim is made that exceeds the limit of an underlying liability policy. It’s similar to having an additional insurance policy on top of your existing coverage.

For example, if you had $2 million in general liability insurance and faced a $2.75 million claim, you and your business would have to cover the $750,000 that exceeds your general liability limits.

If you had an excess liability policy of, say $1 million or more, on top of your general liability insurance, your excess liability coverage would cover that $750,000 loss with higher limits that keep you financially protected.

Many small business owners use excess liability insurance as a cost-effective way to increase the limits on their underlying coverage, for any claims that might exceed their primary insurance coverage. It's often used to boost coverage on general liability insurance or errors and omissions insurance (E&O), also called professional liability insurance.

How does excess liability insurance work?

Your existing liability insurance comes with two kinds of limits: per occurrence and aggregate.

A per-occurrence limit is the maximum amount that your insurer will pay for a single covered loss under your policy. An aggregate limit is the maximum amount that a policy will cover in any one-year period.

For example, say your commercial auto liability coverage has a $500,000 aggregate limit and a per-claim limit of $25,000 for bodily injury and property damage. If a single accident exceeded this $25,000 limit, you and your business would have to cover the additional expense.

If your business exceeded $500,000 in claims over an entire year, your commercial auto policy would still only cover $500,000.

With an excess liability policy, you would be financially protected if any claims exceeded your per-occurrence and aggregate coverage limits.

Keep in mind that an excess liability policy only applies to one underlying policy. To increase liability coverage across multiple policies, look to commercial umbrella insurance.

Who needs excess liability insurance?

Excess liability insurance protects your business from catastrophic losses and claims that exceed the coverage limits of your liability policy, thereby reducing the chance that a lawsuit could bankrupt your business.

Small business owners usually buy excess liability insurance to fulfill the terms of a lease or client contract.

Some business owners opt for excess liability coverage because they face substantial risks, such as:

  • A high degree of foot traffic
  • The handling or transportation of hazardous materials
  • The personal injury claims that could be leveled against construction, manufacturing, or similar businesses

How much does excess liability insurance cost?

Businessperson calculating the cost of excess liability insurance.

This policy costs about $480 in annual premiums for each $1 million of additional coverage. Several factors affect excess liability insurance costs, including:

  • Coverage limits
  • Location
  • Number of years operating
  • Number of employees

What other factors impact excess liability costs?

The cost of excess liability insurance can also depend on your industry and any inherent risks associated with that industry.

For example, someone who works in construction or manufacturing is likely to face more liability claims and pay higher premiums for excess liability coverage, compared to someone who does consulting work out of their own home.

What is the difference between excess liability insurance and commercial umbrella insurance?

Although the two terms are often used interchangeably, excess liability and commercial umbrella insurance mean two different things.

Excess liability insurance is an added layer of financial protection for one designated liability insurance policy, such as your general liability insurance. Your excess liability coverage would activate if you face a claim that exceeds your general liability coverage limits.

Umbrella insurance provides additional coverage for several liability policies. Your umbrella policy would kick in whenever you face a claim that exceeds the coverage limits of one of these underlying policies. It's usually applied to general liability insurance, commercial auto insurance, hired and non-owned auto insurance, and employer’s liability insurance (part of workers' compensation).

For example, if a local retail shop has a customer slip and hit their head on a shelf, it could lead to an expensive legal battle. Between the lawyer’s fees and damages, that retail store owner could owe in excess of $2.1 million, but they may only have a general liability insurance policy with a $2 million per-occurrence limit. Their umbrella coverage would help pay for expenses that exceed that policy's limit, in this case covering the additional $100,000 or more owed.
