Policy Returns

At UNDERUN, we strive for 100% customer satisfaction. Are you not happy with your UNDERUN or do you need a different size? No problem. Below, you will find the exact conditions for returning or exchanging UNDERUN products.

How many days do I have to return or exchange the UNDERUN?
You can return the UNDERUN within 30 days without any problems for any reason. After this period, you can only return the UNDERUN if it broke or has lost its functionality due to production errors.

My UNDERUN used to fit, but I gained/lost weight. What should I do?
This can happen, of course! Due to losing or gaining weight, clothing and accessories can fit differently. Unfortunately, this is not included in the warranty.

I took the tags off my UNDERUN. Can I still return it?
Yes, you can! If you purchased the belt less than 30 days ago, all we need is your name and order number.

I am super-happy with your service. Can I express than somewhere?
We love to hear from satisfied customers, of course. It is also important to us that potential customers hear other people’s opinions, so that they will know what to expect. It would be very helpful to us if you left a review at: Facebook.com/underunuk/ or at: underun.co.uk.

Easy: you download the return form using the button at the bottom of this page and complete it. Send the products and the form by package delivery service, to:

Do you have a packing slip or invoice? Please include a copy.
If you are returning the products because you received something in error, we will cover the shipping costs. If not, the sender is responsible for the shipping costs. These generally vary between €2.45 and €6.95.
