Is Knorr legit?

Legit

Knorr is a genuine kitchen brand, the stock cubes, stock pots and gravy pots found in almost every UK supermarket. The usual sore point is change: when Knorr reworks a recipe, a cube or pot you have cooked with for years can taste different.

What we checked

  • Brand dating from 1838
  • Sold in the UK since 1949

Watch out for

  • A favourite stock pot or cube that tastes different from your last pack after a recipe update.
  • A stock pot that split or leaked, where the claim needs the barcode, manufacturing code and best-before date from the pack.
  • Throwing away the packaging before noticing a fault, which leaves no codes to tie the product to a batch.

Knorr stock pot split open in the pack?

We help you write it, it gets its own public page, and you can have it sent to Knorr as a formal letter.

How do I contact Knorr customer service?

Knorr customer service in the UK is on 0800 731 1411, the consumer careline Unilever UK prints for Knorr. The Knorr UK site has no messaging form, so the other route is a letter to the postal address on the Knorr contact page, linked in the contact details above. Have the pack in front of you: consumer care usually asks for the product name and size, the barcode, the manufacturing code, the best-before date, and where and when you bought it.

Pack not as it should be? Start your complaint here too, and we push it out to Unilever UK by email, social media and printed letters.

What should I do if something is wrong with a Knorr product?

If a Knorr stock pot, stock cube, gravy pot or soup looks or smells wrong, comes in a split or unsealed pack, or contains something that should not be there, stop using it and keep the product and its packaging. Photograph the pack, the barcode, the manufacturing code, the best-before date and anything you found, and keep the receipt or the online grocery order.

If anyone feels unwell after eating it, get medical advice and note the symptoms and the time. Then call Knorr consumer care on 0800 731 1411 with the codes and the name of the shop, and ask for a reference number.

Found something in a stock pot that should not be there? Open a case through our complaint process: our trained AI keeps coaching you on what to send Unilever UK and when to push again.

Can I get a refund for a faulty Knorr product?

For a faulty Knorr product bought in the UK, the quickest route to a refund or replacement is usually the shop that sold it: take the product and the receipt back, or report the item through your online grocery order. Under UK consumer law, the retailer that sold a faulty item is responsible for putting it right. You can also tell Knorr consumer care on 0800 731 1411 about the fault, with the codes from the pack and the name of the shop, and ask what Unilever UK can offer.

Refused a refund on a pack that was faulty when you opened it? We help you write the complaint in minutes, with the photos, the pack codes and the receipt side by side.

Who owns Knorr?

Knorr is owned by Unilever, and in the UK it is sold by Unilever UK Limited. The brand began in 1838, when Carl Heinrich Knorr started his business in Heilbronn, Germany; the stock cube followed in 1912, and Knorr came to the UK and Ireland in 1949, with its first UK factory in Welwyn Garden City. Knorr joined Unilever in 2000. Questions or complaints about any Knorr product sold in the UK go to Knorr consumer care on 0800 731 1411.
