What is your return policy?
We offer a 30-day return policy, meaning you have 30 days from the date you receive your item to request a return. To qualify, the item must be unused, unworn, in its original condition with tags attached, and in its original packaging. You’ll also need your receipt or proof of purchase. To initiate a return, contact us at info@automotorparts.co.uk, and if approved, we’ll provide a return shipping label and instructions. Returns should be sent to: 125 Deansgate, Manchester, M3 2BY. Note that items sent back without prior approval won’t be accepted. For EU customers, you also have a 14-day cooling-off period to cancel or return your order for any reason, provided the item meets the same conditions.

If your order arrives defective, damaged, or isn’t what you ordered, please inspect it upon delivery and contact us immediately at info@automotorparts.co.uk. We’ll assess the situation and work quickly to resolve it—whether that means a replacement, refund, or other solution. Your satisfaction is our priority, and we’re here to make it right.
What items cannot be returned?
Some items are non-returnable, including perishable goods (e.g., food, flowers, or plants), custom or personalized products, personal care items (e.g., beauty products), hazardous materials, flammable liquids, or gases. Sale items and gift cards are also non-returnable. If you’re unsure about your specific item, feel free to reach out to us at info@automotorparts.co.uk for clarification.
