60 Day Returns Policy

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

2. Contact our Customer Services Team on 02476 369890 (or e-mail info@audiovolt.co.uk). We will then send you an RMA number and returns form which needs to be completed and sent back with the returned item(s).

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 have assumed 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 72hrs 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.
