If all item(s) are in stock and your order was placed before 2pm, subject to passing necessary checks, your order will be shipped the same day. Orders received just after 2pm are also often dispatched the same day, but this cannot be guaranteed.


Delivery Options

Due to the nature of the products we sell, we operate a strict fraud screening process and therefore we are only able to deliver to the billing address.

In the event of a delay, we will contact you either by email or telephone as soon as reasonably possible.

While 99% of UK locations are valid for next day/Saturday delivery, there are a few remote locations which are not covered.

Synthax Audio (UK) cannot deliver outside of the UK and Republic of Ireland*.

*RME products cannot be shipped to the Republic of Ireland.


Missed Deliveries

If you are not in to receive the order at the time delivery is attempted, a card will normally be left to notify you of the missed delivery attempt. This will allow you to either telephone the courier company to arrange a re-delivery at a more convenient time or collect it from your local courier depot or Royal Mail sorting office. For security reasons, all items require a signature.

If for any reason the item is returned to us (e.g. incorrect address specified, multiple failed delivery attempts), then we will inform you immediately by email as soon as we receive the item. From this point forth, you will be given a choice whether you wish us to re-dispatch the item or cancel the order. Please refer to our Cancellations & 14 Day Returns Procedure for more details. For items where delivery failed through no fault of Synthax Audio (UK), you will be liable for the original shipping charge, any courier surcharges and any subsequent delivery charges.


Late Deliveries or Dispatch

We are able to ship almost every order in the specified timescale. However, in very rare circumstances there can be an unforeseen delay. If this does happen, we will make it our priority to get your order dispatched from our warehouse as soon as reasonably possible.

There are also rare cases, beyond our control, when the delivery company itself has a problem which causes a delay in transit. In these situations we will do our utmost to liaise with the relevant delivery company to ensure delivery is completed as swiftly as possible.

Consequential Loss for Late Deliveries

If a delivery is late, then we will provide a refund of any delivery fee that we charged you. We do not provide financial compensation to cover consequential losses, e.g. for time taken off work to receive a delivery, or if the item is intended as a gift and you have to purchase the same item from a more expensive retailer.
