    Certain items are excluded from the returns or refund policy. These include goods that are made to measure, cut, or mixed to your requirements. Orders which involve different cutting lengths and order value of more than £100 don't qualify for any refund or return if there is no fault with the product. The reason for this is because these are classified as custom orders where different lengths of led strip lights and led neon flex are cut to your desired requirement of the customer. It takes a lot of time and effort to prepare these orders. The lengths are cut from a 50 metre roll and prepared as per your desired lengths so custom orders wont be returned or exhanged.

    Please note that any amendments done to the lights voids the warranty on the product.
