    60 Day Returns Policy

    We ask that you follow these guidelines to help us process your return as quickly and efficiently as possible:

    1. Please keep your order reference to hand. This confirms your original order and gives us the necessary details to authorise the product's return.
    2. Contact our Customer Services Team on 02476 369890 (or email info@audiovolt.co.uk). We will then send you an RMA number and a returns form, which needs to be completed and sent back with the returned item(s).
    3. If the order has been unpacked, re-package it to ensure that it is being returned in its original condition. Please make sure all items relating to the product are returned, including manuals and cables.

    Returned items must be mailed within 10 days of when the RMA number has been issued. Items received with a post date 30 days after your requested return will NOT be eligible for refund.

    Please note: our returns policy is quite straightforward, but there are a number of conditions that we ask our customers to comply with before applying:

    1. It is your responsibility to request a return. If you don't tell us you want to make a return, we don't know. Once you do tell us, we will do everything we can to action it.
    2. If you have not requested a return within 60 days of receiving an order, we will assume that you are intending to keep it, and we will not authorise a return.
    3. We always refund the payment according to how the original purchase was made and aim to do so within 72 hours of the return being received by us.
    4. Returned goods are liable for a restocking fee of 15% towards handling and repackaging if the order is not returned in its original, unopened packaging. This charge will be subject to our inspection of the returned goods.
    5. Delivery charges will not be refunded unless the delivered goods are faulty.
    6. Replacement products are dispatched immediately after the returned goods have been received and accepted by Audio Volt.
    7. Items that develop a fault within 30 days of delivery are eligible for a replacement or a refund. Delivery costs are also reimbursed for faulty items. Please contact our Customer Services Team on 02476 369890 if you believe your item has developed a fault.

    Finally, please remember that notifying us of your intention to apply for a return, saving the delivery paperwork and keeping the order in its original packaging will help both you and Audio Volt to process the return quickly.
