Delving into the world of business insurance can seem like a whirlwind, and that’s before you come across public liability insurance vs products liability. They sound pretty similar (and they are) but they actually cover different things.

To best protect your business against claims, it’s super important to make sure you have the right cover for your needs.

If you’ve been scratching your head trying to understand public liability vs products liability, don’t worry – we’ll be outlining the difference below with some claim examples so you can make sure you get the right insurance.

*Disclaimer – this a general guide to insurance and exact coverage, conditions and exclusions may differ per policy and insurance provider.Please always check your policy documentation and/or terms & conditions for more details.

What’s the difference between public liability and products liability insurance?

Public liability insurance and products liability insurance are similar in that they both cover compensation and legal costs in relation to claims of accidental third-party injury or property damage.

In both cases, the insurer will only respond if your business is found legally liable for the injury or damage.

Where they differ comes down to the cause or trigger of a claim:

  • Public liability insurance – covers claims arising from you/your business activities
  • Products liability insurance – covers claims caused by products you/your business manufactures, supplies or installs

Many businesses hold both types of cover because claims can arise unexpectedly from day-to-day activities or from the products they supply.

So, what exactly does each one cover?

What is public liability insurance?

Public liability (PL) insurance provides financial protection for claims where you/your business is held liable for accidental bodily injury or property damage to third parties.

Think of it as a safety net if someone gets hurt or their property is damaged because of something your business did (or didn’t do).

This type of cover helps with the legal costs and any compensation you might have to pay. Think of it as protection for those “just in case” moments – like a customer tripping over a loose cable in your shop or you accidentally damaging client equipment while visiting their office.

What can public liability cover?

Public liability insurance covers costs including:

  • Compensation payments
  • Repair costs
  • Professional fees (i.e. legal advisors etc.)
  • Medical costs

Public liability is typically operated on a ‘claims occurring’ basis. That means it will cover claims for incidents that occurred during the policy period even if your claim is made months or years after the policy end date.

It’s important to remember that if poor workmanship plays a part in causing an incident, you may not be fully covered – public liability may cover injury or damage caused by the failure, but not the cost of refitting or repairing the faulty work itself.

Public liability insurance claim examples

  • A freelancer knocks over and breaks a client’s specialist equipment while visiting their office
  • A tradesman installs a shelving unit that falls and causes injury to someone else (injury claim covered, not poor workmanship)
  • A client trips over a freelancer’s trailing laptop charger cable
  • A carpenter drills through a water pipe, causing water damage to surrounding areas (damage covered, not poor workmanship)

What is products liability insurance?

As mentioned above, products liability insurance is very similar to public liability in that it also covers accidental third-party injury or damage.

But where public liability applies to damage or injury caused by business activities, products liability instead covers claims caused by the products/goods you supply or manufacture (or their packaging). This is provided the claim arises from a defect in the product rather than the installation work itself.

What can products liability insurance cover?

Products liability insurance can also cover costs including:

  • Compensation payments
  • Repair costs for property damage
  • Legal fees to defend a claim
  • Medical costs

Products liability is also operated on a ‘claims occurring’ basis – you’ll be covered for incidents that occurred during the policy period even if your policy has since expired.

It also won’t cover poor workmanship – injury or damage caused by the product may be covered, but not the cost of refitting or repairing it if it was installed incorrectly in the first place.

Products liability insurance claim examples

  • A product has a design defect, causing injury to a customer even after following instructions
  • A toy breaks and injures a child
  • A product a contractor installs turns out to be defective and causes a fire (damage caused by product defect covered, not faulty installation/poor workmanship)
  • An installed boiler turns out to be faulty, leaking water and damaging the room it’s fitted in
