We at Nestly Home want to make sure that all of our trade customers have a simple and reliable wholesale experience. We are sure that our products and packaging are of high quality, but we know that sometimes things need to be sent back. That's why we've made a clear and simple Returns Policy that puts your business first.

Return Window

You have 14 calendar days from the day you get your order to start a return. Please call our customer care staff with your order number, item information, and reason for return to start the return process. We may not accept returns requested after this time. 

Conditions for Eligible Returns

We will take back items for the following reasons:

• Items that were damaged when they got to you
• Items that were sent to the wrong address
• Extra or undesired stock (if not used and still in the original packing)

All returns must be in resalable condition and have their original packing. We won't accept returns for items that show indications of use, have been damaged by mishandling, or are missing parts.

Things That Can't Be Returned

Our return policy does not cover some items, such as;

• Items that were made to order or are on clearance or end-of-line stock
• Items that were opened for hygiene reasons
• Items that were returned beyond the 14-day timeframe

If your item fits into one of these groups, please talk to our customer service staff to see what other options you have. 

Claims and Damaged Goods

You have to tell us about the problem within 48 hours after delivery if your order is damaged. Please send clear pictures of the damage to both the package and the product itself. This lets us file a claim with our shipping partners and quickly start the process of getting a new item or a refund.

If you don't report damages within this time limit, your claim may be denied because courier policies require strict respect for reporting dates.

How to Return

To return something, just do these easy things:

1. Contact Us: Within 14 days of delivery, email or call our customer support staff.
2. Return Authorisation: We will give you a Return Authorisation Number (RAN) and instructions on how to send it back.
3. "Pack and Send": Put the things back in their original packaging and include your RAN and original invoice.
4. Shipment: The buyer is responsible for paying for the return shipment unless the item was damaged or sent back by mistake.
5. Inspection: Items will be looked at within 3–5 business days of being received.
6. Refund/Replacement: If approved, a refund will be sent or a new item will be provided.

Fees for Restocking

If you return something for a reason other than damage or an error (for example, if you have too much stock or change your mind), you may have to pay a restocking fee of up to 15%. This helps us pay for the costs of handling, inspecting, and repackaging.

Money Back

The same way you paid for your order is how approved refunds are handled. After acceptance, refunds usually show up in your account within 5–7 business days. If your return is denied after being looked at, you can either pay for the item to be sent back to you or provide permission for it to be thrown away.

Swaps

We don't do direct trades. Please place a new order for a different product if you need one. As explained above, your refund for the returned item will be executed. 

Returns from Other Countries

Returns are allowed from customers outside the UK as well. But the buyer has to pay for return shipment, customs fees, and any delays. We suggest choosing a tracking service and keeping your evidence of shipping.
