Important Safety Warning: Beware of fake customer service numbers on search engines. Only use official channels. Scammers frequently buy ads to promote fraudulent phone numbers. Aldi staff will never ask for your account PIN or ask you to move money to a “safe account” over the phone.
Level 1: Customer Support (Initial Complaint)
-
How to complain: You can raise a complaint via their online contact forms or by calling their dedicated customer service routing number. If your complaint is regarding an in-store purchase, you can also speak directly to the Store Manager at your local Aldi.
-
General Enquiries & Complaints: 0800 042 0800

Source Verification Note: Aldi Help & Contact Portal
-
Availability: The customer service phone lines are generally open Monday to Saturday from 8:00 AM to 8:00 PM, and Sunday from 10:00 AM to 4:00 PM (UK Time).
-
Timeline: Aldi aims to resolve initial retail complaints within 7 to 14 working days.
Level 2: Formal Corporate Escalation (Notice of Dispute)
-
Who to contact: If standard customer service cannot resolve the issue, you must formally escalate it in writing. Send a letter detailing your receipt/order number, a timeline of the issue, and your desired resolution. You must explicitly request a “Deadlock Letter” if they refuse your proposed resolution.
-
General Retail Complaints Address: Customer Service Department, Aldi Stores Limited, Holly Lane, Atherstone, Warwickshire, CV9 2SQ
-
Timeline: Under UK consumer law guidelines, Aldi has a maximum of 8 weeks to issue a final resolution or a Deadlock Letter.
Level 3: Regulatory Authority (The Financial Route)
- Authority: Your Bank
- The Reality: There is no statutory retail ombudsman for Aldi. If they refuse to refund you for faulty Specialbuys, expired food, or a Click & Collect issue, you must contact your bank and claim a breach of contract under Section 75 of the Consumer Credit Act (for credit cards) or request a Chargeback (for debit cards).
- Timeline (CRITICAL): You do not need to wait 8 weeks to initiate a Chargeback if Aldi has already explicitly refused your refund in writing (e.g., via email or a formal letter).
Level 4: Legal Action (Final Step)
-
Pre-Litigation: Before commencing legal proceedings, UK legal protocols require you to send a formal “Letter Before Action” (LBA). You must address it to their exact corporate legal entity: Aldi Stores Limited.
-
Legal Address: Legal Department, Aldi Stores Limited, Holly Lane, Atherstone, Warwickshire, CV9 2SQ
-
Court: If the LBA fails and your bank refuses a chargeback, you can file a lawsuit. For financial claims up to £10,000 in England and Wales, you can use the Money Claim Online (MCOL) portal to enter the Small Claims Track.
