FAQs
Please read our FAQs page to find out more.
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.
How do I report a damaged or incorrect item?
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.
How does shipping work, and how long will it take?
We ship from our UK location and offer reliable options tailored to your needs:

- Other International Destinations: Standard International (3-17 business days) to select countries like the UAE, Australia, and Canada—check eligibility at checkout.
Delivery times are estimates and may vary due to location, customs (for international orders), or product specifics (e.g., bulkier items like batteries). Customs duties and taxes, where applicable, are your responsibility. Exact shipping options and times will be shown at checkout.
When will I receive my refund?
Once we receive and inspect your return, we’ll notify you if it’s approved. If approved, your refund will be processed to your original payment method within 10 business days.
