Refund and returns

Refund and Returns Policy (B2B)

Version 1.1, 2026-07-30

1. Scope: business customers only

All offers on de-linker.com are directed exclusively at businesses, installers, and EPCs. Partner accounts are reviewed before online ordering is enabled. No contracts are concluded with consumers, so statutory consumer withdrawal rights do not apply to any order placed through this site, as set out in the Terms of Sale. This policy sets out how de-linker handles order errors, transport damage, warranty claims, and returns for business customers.

2. Order errors and transport damage

Check a delivery against the order confirmation on receipt. If the wrong product, the wrong quantity, or a shortage arrives, contact de-linker with the order number before the goods are used or installed. If a delivery arrives with visible transport damage, document it with the carrier at the point of delivery, as required under the Terms of Sale, and notify de-linker with photos and the order number.

3. Warranty claims

A warranty claim goes through Linker: we run it for you under the product's stated warranty terms.

de-linker keeps the order record, the serial numbers, and the delivery documents that a claim needs, and routes the claim on the buyer's behalf. de-linker does not issue its own warranty and does not test or certify returned hardware; the product's published warranty terms, available with its documents on the product page, govern the outcome.

4. Returns outside a warranty claim

A return outside a warranty claim is not a standing right for business customers and is handled case by case. Contact de-linker with the order number before sending anything back; a return needs written authorisation before goods are shipped. An authorised return must be unused, in its original packaging, and accompanied by the order documents. Freight for an authorised return, and any restocking or handling charge, are agreed in writing at the time the return is authorised. de-linker does not accept unauthorised returns shipped without prior agreement.

5. Refunds

Where a refund is due, whether for a confirmed order error, transport damage, or an authorised return, de-linker issues it to the original payment method or as a credit against the buyer's account, as agreed with the buyer. A refund is processed once the returned goods are received and checked, or once we have confirmed the warranty claim.
