Is Dolmio legit?

Legit

Dolmio sauces are made by Mars, so the brand is as genuine as it gets, and questions are usually about one jar rather than the company. If a sauce is mouldy under the lid or holds something odd, the batch code and best before date on that jar tie the problem to its production run.

What we checked

  • Sold in the UK since 1986
  • Created in Australia in 1985

Watch out for

  • A jar that is fizzy, mouldy or smells off when you open it, well before its best before date.
  • Something hard or unexpected in the sauce, with the jar and its batch code already thrown away.
  • A new jar whose lid is loose or already unsealed when you get it home.

Found something odd in your Dolmio jar?

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

We help you write an effective complaint in minutes. Our AI models are trained on thousands of effective complaint letters. Then we push it through emails, social media, paper complaint letters and other tools at our disposal. And you are not alone: our helpful community is there for advice.

How do I contact Dolmio customer service?

Dolmio customer service in the UK is on 0800 952 1234, the line Dolmio gives for questions, comments and product information, or use the contact form on the Dolmio website, linked in the contact details above. Have the jar or pack in front of you: consumer care usually asks for the product name and size, the best before date and the batch code printed on the pack, and where and when you bought it. Keep the product until the matter is settled.

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

What should I do if something is wrong with my Dolmio sauce?

If a Dolmio sauce or meal smells or tastes off before the date, looks mouldy, fizzes, has a loose or damaged lid, or contains something that should not be there, stop eating it and keep the jar with what is left in it in the fridge. Photograph the jar, the best before date, the batch code and anything you found, and keep the receipt or the online order confirmation.

If anyone feels unwell after eating it, get medical advice and note the symptoms and the time. Then tell Dolmio consumer care on 0800 952 1234 or through the contact form, quoting the codes and the shop, and ask for a reference number.

Found something in the jar that should not be there? Open a case with us through our complaint process: our trained AI keeps coaching you on what to send Mars Food UK and when to push again.

Can I get a refund for a faulty jar of Dolmio?

For a faulty Dolmio product bought in the UK, the quickest route to a refund or a replacement is usually the supermarket that sold it: take the jar and the receipt back to the store, or report the item through your online grocery order. Under UK consumer law, the shop that sold a faulty item is responsible for putting it right. You can also tell Dolmio consumer care on 0800 952 1234 about the product, with the date, the batch code and the shop, and ask what Mars Food UK can offer.

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

Who makes Dolmio?

Dolmio is a brand of Mars, Incorporated, and in the UK it is sold by Mars Food UK Limited, the Mars food business based in Slough. The brand began as Alora, a 1985 test launch in Australia, and was renamed Dolmio; the UK site dates the brand to 1986. The UK range covers Bolognese and lasagne sauces, pasta and pasta bake sauces, stir-in and meatball sauces and microwaveable ready meals, and questions or complaints about any of them go to Dolmio consumer care on 0800 952 1234. Ireland, Australia and the Nordic countries have their own Dolmio sites.
