We aim to process orders the same day and will contact you should your item be out of stock or delayed for any reason and offer you either a new delivery date or a refund.

We have a 30-day return policy, which means you have 30 days after receiving your item to request a return.

To be eligible for a return, your item must be in the same condition that you received it, unused and in its original packaging. You’ll also need the receipt or proof of purchase.

To start a return, you can contact us at shop@avensys.co.uk. Please note that returns will need to be sent to the following address: Returns at Avensys House, Fleming Way, Crawley, RH10 9JY. Please quote your order number and reason for return.

If your return is accepted, we’ll send you a return shipping label, as well as instructions on how and where to send your package or organise a DPD collection. Items sent back to us without first requesting a return will not be accepted.

The Buyer will be liable for the cost of remedying any damage to the Goods returned where such damage has, in the opinion of the Seller, been caused by the Goods being inadequately packaged by the Buyer. Or through the Buyer's fault. 

You can always contact us for any return question at shop@avensys.co.uk.
