Are manufacturers liable for products sold online?

Yes, manufacturers can still be liable when products are sold online. In the UK, the fact that a product is listed on a website or sold through a marketplace does not remove the manufacturer’s responsibility if the product is defective.

Liability usually depends on whether the product caused damage or injury because it was unsafe. A consumer may have a claim against the manufacturer, seller, or another party in the supply chain, depending on the facts.

What law applies in the UK?

Product liability in the UK is mainly governed by the Consumer Protection Act 1987. This law allows claims where a product is defective and causes personal injury or certain types of property damage.

A product is considered defective if it is not as safe as people are generally entitled to expect. Courts look at the product’s presentation, warnings, instructions, and the time it was supplied.

What if the product was sold through a third party?

Manufacturers are not automatically protected just because a third party sold the item. If a distributor, reseller, or online marketplace handled the sale, the manufacturer may still be liable if the defect came from the product itself.

However, the seller may also have separate legal responsibility. A consumer often has more than one possible defendant, which can be useful if the manufacturer is overseas or difficult to identify.

Do online marketplaces have responsibility too?

In some cases, yes. Online marketplaces may have obligations under consumer law, especially if they play an active role in selling, storing, or distributing the goods.

That said, the main liability often still falls on the manufacturer or the business that placed the product on the market. The exact position can depend on whether the marketplace acted only as an intermediary or as part of the supply chain.

What should consumers do if they are harmed?

Anyone injured by a defective product should keep the item, packaging, receipts, and any online listing details. These records can help show where the product came from and who supplied it.

It is also sensible to report the issue to the seller and manufacturer as soon as possible. If the injury or loss is significant, legal advice can help identify the right defendant and explain the time limits for bringing a claim.

Bottom line

Manufacturers can be liable for defective products even when those products are sold online or through third parties. The route of sale does not usually cancel out responsibility for safety.

For UK consumers, the key questions are whether the product was defective, whether it caused harm, and who sits in the supply chain. In many cases, more than one business may be legally responsible.
