Returns
If you are unhappy with the goods in any way, you can return them within 30 days of the delivery date. For a refund, it's essential to ensure that all items are returned in their original packaging, along with accompanying documentation and manuals, in an undamaged and complete state.
It's important to note that the Consumer Contract Regulations safeguard all online purchases, granting you the ability to cancel an order within 14 days of receiving the item. The right to cancel doesn't apply to products that have been custom-made for you, such as components of a heating system or in-store discounted items not typically stocked.
30 Days From Purchase
We have, however, extended this time, and we will accept returns within 30 days from the day that you receive your item. You should be aware that any refund for returns will not include the original cost of enhanced shipments such as Tracked 24 or Guaranteed Next-Day Delivery. It should also be noted that items must be returned in an unused and resellable condition with unopened manufacturer packaging if sent that way, with any security packaging also intact.
We’ll also provide a return shipping label if the return is a result of our error (you received an incorrect or proven defective item, etc.). If this facility is used and the item does not prove to be incorrect or defective, we will deduct the cost of the return postage from the refund.
You should expect to receive your refund within one week of giving your package to the return shipper; however, in many cases, you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper, the time it takes us to process your return once we receive it, and the time it takes your bank to process our refund request.

Your input is very much appreciated. Share it with your friends so they can enjoy it too!
This Alphi-11 product is great. I never have any issues and highly recommend it for it's effectiveness. No burst pipes and the system is still running smoothly.
I had 2 items delivered but Royal mail must have been playing football with it. They were very well packaged when I opened to see why one had leaked, so not sure why this happened. The service was excellent and a replacement was sent immediately. Thank you Harry O'Connor!
