Product Liability vs Public Liability Insurance: What’s the Difference?

As a business owner, navigating the world of insurance can be confusing. Two types of cover that often cause uncertainty are public liability and product liability insurance. Whilst their names sound similar, they protect your business against very different risks. Understanding the distinction is vital - having the wrong cover, or no cover at all, could leave your business financially exposed if a claim is made against you.

This guide clarifies the difference between the two. In short, public liability insurance covers claims arising from your business’s activities, such as a customer slipping on your premises. Product liability insurance, on the other hand, covers claims of injury or damage caused by a faulty product that you have sold or supplied.

What Is Public Liability Insurance?

Public liability insurance is designed to offer financial protection if a third party - such as a client, a customer, or a member of the public - claims they have been injured or that their property has been damaged because of your business operations. It can pay for the legal fees to defend your business against a claim, as well as any compensation you are required to pay if found liable.

For most businesses in the UK, public liability insurance is not a legal requirement. However, it is strongly recommended for any company that interacts with the public. Many clients, particularly government bodies and larger organisations, will require you to have a certain level of cover before they agree to work with you. It is especially important for sole traders, who are personally liable for business debts and compensation claims. For more detail, see our guide, What Is Public Liability Insurance?.

It’s important to know that this policy only covers claims made by third parties. It does not cover accidents involving you or your employees. If you have staff, you are legally required to have employers’ liability insurance to cover them. You can learn more in A Guide to Employers’ Liability Insurance.

Cover levels for public liability typically range from £1 million to £10 million. The amount your business needs will depend on the nature of your work and the level of risk involved. For many small businesses, a cover level between £2 million and £5 million is considered sufficient.

What Is Product Liability Insurance?

Product liability insurance protects your business if a product you design, manufacture, or supply causes injury, illness, or damage to property. Like public liability, it covers the associated legal costs and compensation payouts if your business is held responsible for the fault.

You can be held liable for a faulty product even if you didn’t manufacture it. For example, you could be responsible if your business’s name is on the product, if you have repaired or refurbished it, or if you have imported it from outside the European Union. For this reason, product liability insurance is highly recommended for any business that deals with physical products, even if they are given away for free as part of a promotion.

This insurance can cover unforeseeable circumstances, such as a fault that even a robust quality control system could not have detected. Policies generally operate on a “claims occurring” basis, which means you are covered for incidents that happened while the policy was active, even if the claim itself is made after the policy has expired.

Key Differences at a Glance

The fundamental difference between the two policies lies in the source of the potential claim. Public liability insurance relates to your business’s actions and premises. It covers incidents connected to the way you run your operations or deliver your services. Product liability insurance relates to the items you sell or supply, covering harm caused by a defect in those goods.

A public liability claim is triggered by an event like a customer tripping over a loose tile in your shop or a consultant spilling coffee on a client’s laptop. A product liability claim is triggered by a fault in an item you’ve supplied - for instance, a cosmetic product causing a skin reaction or an electronic gadget overheating and causing a fire. The harm can occur long after the customer has left your premises.

Real-World Scenarios

Scenario 1: A Slip in Your Shop

A customer is visiting your retail store. An employee has just mopped the floor but forgotten to put out a ‘wet floor’ sign. The customer slips, falls, and fractures their wrist. They are unable to work for several weeks and make a claim against your business for their injury and loss of earnings. In this case, your public liability insurance would respond. The injury was a direct result of your business activities - specifically, failing to maintain a safe environment - so the policy would cover your legal defence and any compensation awarded.

Scenario 2: A Faulty Product Causes Harm

You run an e-commerce business selling kitchen gadgets. A customer buys a blender that you stock. Due to a manufacturing defect, the blade detaches during use, shattering the container and cutting the customer’s hand. They require stitches and make a claim against you. This is a clear case for product liability insurance. The harm was caused by a faulty product you supplied. Even though you didn’t make the blender, as the seller you can be held liable, and your product liability policy would cover the costs.

Do I Need Both Types of Insurance?

If your business sells or supplies physical products to the public, the answer is very likely yes. Public liability insurance alone will not protect you from claims arising from faulty goods. If you have a shop, café, or office that customers visit, you need public liability cover for accidents on your premises. If you also sell products - from coffee beans to kitchenware - you need product liability cover for the risks associated with those goods.

Even online sellers working from home should consider both. A courier could trip and injure themselves while collecting a parcel from your home, triggering a public liability claim. Meanwhile, a customer anywhere in the country could be harmed by a product you’ve sold, leading to a product liability claim. For this reason, many insurers offer public and product liability insurance together as a combined policy.

How Much Does This Insurance Cost?

The cost of business insurance is specific to your company and its risks. You can get quotes directly from insurers or use a comparison service to review the market. The final premium will depend on several factors:

• Your business type: A restaurant or a business selling electronics is seen as higher risk than a bookshop.

• Business size and turnover: Higher turnover often means more customers and greater exposure to risk.

• The level of cover: A policy with a £10 million limit will cost more than one with a £2 million limit.

• Your claims history: A business with no prior claims will typically pay less.

While prices vary, some insurers publish starting figures. For public liability, Markel Direct offered cover from £5 per month as of September 2026. For product liability, which is usually bundled with public liability, Simply Business quoted prices from £5.40 per month in June 2026. A combined policy for a £5 million limit was offered by the CMTIA from £69.00 per year for policies starting in January 2026. These figures are indicative, and you will need a personalised quote to find the exact cost for your business.

Choosing the Right Cover for Your Business

Ultimately, deciding between product and public liability insurance - or taking out both - comes down to analysing your business’s unique risks. By considering how you interact with customers and what you provide them, you can ensure you have the right protection in place.
