Muller customer service in the UK and Ireland works through web forms on the Müller website rather than a published phone line or email address. The contact page, linked in the contact details above, splits into Müller Yogurt & Desserts, for the yogurt and chilled dessert brands, and Müller Milk & Ingredients, for fresh milk and dairy ingredients, and each has one form for enquiries and another for complaints. Have the pot or carton with you: the complaint route asks for the brand, the product, the best-before date, the code on the lid and the store where you bought it.

Pot not right? Start your complaint here at the same time, and we push it out to Müller by email, social media and printed letters.

If a Müller yogurt, rice pot or dessert tastes sour or fizzy, looks mouldy, arrived split, or has something in it that should not be there, stop eating it and keep the pot with what is left inside, in the fridge. Photograph the product, anything you found, the best-before date and the lid code, and keep the receipt.

If anyone feels unwell after eating it, get medical advice and note the symptoms and the time. Report it to Müller Yogurt & Desserts through the complaints option on its contact page, with the codes and the store name, and ask for a reference. For a refund, the shop that sold it is usually the quickest route, under its own return policy.

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