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.
