Home › Commercial Insurance › General Liability
Third-party injury, property damage, and the certificate your client is waiting for before they sign anything.
The foundational coverage
General liability insurance covers injuries and property damage your business causes to others, plus the legal defence either one triggers. For most Delaware County businesses it is the first commercial policy they buy, usually because a client, landlord, or general contractor demanded proof of it.
That demand is not bureaucracy. The party asking wants to know that if your work injures someone or wrecks something, an insurer with real limits stands behind you, because otherwise their own policy inherits your accident. The certificate is how business gets done, and being unable to produce one quickly is how contracts get lost.
Standard limits run $1 million per occurrence with a $2 million annual aggregate, which is what most contracts specify and most carriers quote by default. The occurrence limit caps any single claim; the aggregate caps the policy year as a whole, and a busy year of small claims can erode it faster than owners expect.
What is covered
Four coverage parts, plus the paperwork machinery that makes contracts work.
A customer slips in your shop, a passerby is hurt by your work: medical costs, settlements, and judgments up to your limit.
The floor your crew gouges, the server your ladder takes out. Damage your operations cause to property that is not yours.
Claims arriving after the job is done or the product is sold, when the defect surfaces months later.
Libel, slander, and advertising missteps, a quieter coverage part that defends reputation claims.
Attorney fees and court costs for covered claims, paid by the carrier even when the claim is meritless.
The proof-of-coverage documents contracts demand, with additional insured endorsements when the contract names them.
Cost
Published small-business averages run from about $45 to $123 a month, with the spread explained by who was measured. Premiums scale on your trade, revenue or payroll, claims history, and limits, so a desk-based consultancy and a roofing crew live at opposite ends of the range.
The sources and their assumptions: Insureon reports a $45 monthly average across its small-business customers, with most choosing $1 million per occurrence and $2 million aggregate limits. Progressive Commercial reports $79 a month for its new customers. MoneyGeek’s 2026 report puts businesses with one to four employees at $123 a month for the same standard limits.

The paperwork that wins work
A certificate of insurance is a one-page snapshot proving your coverage exists, its limits, and its dates. An additional insured endorsement goes further, extending your policy’s protection to the client or landlord named on it. Contracts commonly require both, and the wording matters.
Two practical warnings from years of doing this. First, read what the contract actually demands before signing: primary and noncontractual wording, waiver of subrogation, and specific endorsement forms are all real requirements that your policy either supports or does not. Second, certificate speed is a business capability. When the GC wants the certificate before Friday’s mobilisation, the agency that issues it the same hour is part of your bid.
A certificate is also not the same thing as coverage. It reflects the policy on the day it was issued, nothing more, which is why sophisticated clients ask to be listed as certificate holders: it gets them notified if the policy lapses mid-contract. Expect that request, and treat it as a sign you are dealing with someone careful.

GL is broad but bounded, and the boundaries each have their own policy.
Why independent
Commercial liability pricing is class-code driven, and carriers rate the same class differently on purpose: each is chasing the trades it wants and surcharging the ones it does not. That means the quote you get from one carrier says as much about their appetite as about your business, and only a comparison exposes which is which.
We run the comparison, watch the certificate requirements in your contracts, and keep the account moving when appetite shifts at renewal. Most GL clients start from our business insurance in Drexel Hill, PA overview, add workers comp insurance in Delaware County the day they hire, and fold GL into a business owners policy in Pennsylvania once property enters the picture, because the bundle usually beats the parts.
