Our 14 Day Returns Money Back Guarantee:
For items returned in resaleable condition, with all original packaging. If an item has been opened for inspection but shows signs of use beyond that, a deduction may apply to reflect the reduced value — see our full Terms & Conditions (Section 12) for details.

Returns FAQs

What is your returns criteria?
14 days from date of receipt, or expected date of receipt on non-tracked items.

How do I go about returning my order?
Please contact us via our contact page with your order number. We will provide you with an RMA number and return instructions, including your return deadline and whether a freepost label applies to your order.

Do I need to contact you before returning my order?
Yes, to obtain an RMA number before sending anything back.

Does my item have to include its original packaging?
Yes, to qualify for our 14 day money-back guarantee. For faulty items, we understand you may no longer have the original packaging.

Who pays for return postage?
If your item is faulty, damaged, or not as described, we cover reasonable return postage, or provide a freepost label where available. If you are returning an item for another reason (including simply changing your mind), you are responsible for return postage unless we have expressly confirmed a freepost label in your RMA email — we recommend using a tracked and insured service for items of significant value.

Who deals with the warranty on a faulty item?
We will. In some circumstances we may ask you to contact the manufacturer directly for assistance.

Please ensure you have read and comply in full with Sections 11–13 of our Terms & Conditions.
