Refund policy

BIOFIT® Return and Refund Policy

Effective 31 October 2026

At Biofit, your comfort and satisfaction matter to us. We want you to feel confident in every purchase, and we're committed to helping if something isn't quite right.

This policy explains how we can help with sizing, product quality, delivery problems and refunds. It applies to every order placed on our website, including sale items and special offers. If you have a question that isn't answered here, our Customer Support team is always happy to help at team@biofitclothing.com.

1. A note on hygiene

Because our products include underwear, we follow strict hygiene standards. For health and hygiene reasons, sealed underwear can't be returned once the seal has been opened, unless the item is faulty.

We know you sometimes need to try something on to know if it fits. That's why we offer free size swaps (see below), so you're never stuck with the wrong size. This hygiene rule doesn't affect your legal rights if a product is faulty, damaged or not as described.

2. Not quite the right fit?

Finding your perfect fit can take a little trial and error, and we're here to help. If your BIOFIT® doesn't fit the way you hoped, contact us within 30 days of delivery and we'll send you a different size free of charge.

One free size swap per order.
We'll happily help you choose the right size. You can also check our Size Guide (https://getbiofit.com/pages/size-guide) before you get in touch.
To help us process your request, we may ask for your order number and a photo of the items, and in some cases we may ask you to send the original items back.

If a size swap isn't the right solution for you, just let us know. Our team will look at your situation and do our best to find another way to help.

3. Our 180-day guarantee

We stand behind the quality of everything we make. Our 180-day guarantee covers products bought as part of our Buy 5, Get 5 Free offer (products labelled "5 Pack + 5 FREE"), including the free pairs. If one of these products develops a quality fault within 180 days of delivery, we'll replace it free of charge.

What's covered

Holes or tears caused by a product defect.
Loose, faulty or damaged stitching.
Waistband defects or failures.
Other manufacturing faults.

What's not covered

Colour fading or shrinkage.
Normal wear and tear.
Damage caused by misuse, incorrect washing or care, or anything unrelated to a product defect.

How it works

We replace the affected items only. For example, if 2 pairs from your 5 Pack + 5 FREE develop a fault, we'll replace those 2 pairs.
Each item can be replaced once under the guarantee. A replacement doesn't restart the 180-day period.
If other items from the same order develop a fault later, you can still claim for them within the original 180 days.
Please send us your order number and clear photos of the fault. In some cases we may ask you to send the faulty item back.

Our 180-day guarantee provides free replacements rather than refunds. If you're legally entitled to a refund or another remedy, that right always stays available to you (see section 8).

Bought something else from us? If any product arrives faulty or develops a fault, please contact us. We'll always look after you, and your legal rights for faulty goods still apply (see section 8).

4. Sale and offer items

Everything you buy from us is covered by this policy, including sale items and items from offers such as our Buy 5, Get 5 Free packs. Free items have no cash value, so where a refund applies it's based on the amount you actually paid.

5. Missing, wrong or damaged orders

We know how disappointing it is when an order doesn't arrive as expected. If your parcel is late, lost, damaged in transit, missing items or not what you ordered, please contact us, ideally within 5 days of delivery so we can look into it quickly.

We'll check the tracking details, work with our delivery partners and arrange a replacement or a refund. If it's been longer than 5 days, please still get in touch and we'll help.

6. Cancelling an order

If you need to cancel or change your order, contact us as soon as possible. We can usually make changes before your order is dispatched, but once it's on its way we may not be able to stop it.

If you're a UK customer, you can cancel an online order within 14 days of receiving it, without giving a reason. This doesn't apply to sealed underwear once the seal has been opened. Please contact us before sending anything back and we'll give you the return address. You'll need to cover the return postage unless the item is faulty or we sent you the wrong item. Once we receive the items, or proof that you've sent them, we'll refund you, including the original standard delivery charge.

7. Refunds

Where a refund applies, we'll send it to your original payment method. We aim to start refunds within 2–3 business days of approval, and your bank may take a few more days to show it in your account. Refunds for cancellations are always issued within the time limits set by law.

8. Your legal rights

This policy is in addition to your rights under UK consumer law, not instead of them. If a product is faulty, not as described or not of satisfactory quality, you may be entitled to a repair, replacement, price reduction or refund, and these rights can last longer than our 180-day guarantee. Nothing in this policy limits those rights. You can read more at gov.uk (https://www.gov.uk/accepting-returns-and-giving-refunds).
