CustomDUO Shop

UK Delivery


UK deliveries are typically shipped using a Royal Mail Signed Delivery service. Postage is calculated at a flat rate, based on the total amount of the purchase, as follows.








International Delivery


International orders welcome. We deliver to most (but not all) international destinations, using Royal Mail. 

International deliveries are shipped at no additional postal charge (i.e. at the same postage rate as UK deliveries) using Royal Mail International Standard service. We obtain proof of postage for all orders. If you would like the security of delivery by the Royal Mail International Tracked service, then there is an additional shipping charge of +£5 to be added to your order.

We reserve the right to cancel and refund any order to any destination if we have any concern over it arriving safely. Feel free to contact us if you live off the beaten track or somewhere with a shocking postal service!! We reserve the right to cancel low value international orders if delivery is not cost effective. Please contact us regarding orders <£20.


We aim to despatch CustomDUO stock products within two working days, and generally the next working day. We make every effort to keep our on-line stock availability right up to date (and generally don't get caught out). When placing an order, please ensure that your email address is current, so that we can keep you informed of progress.
All Royal Mail services aim to deliver to Europe within 3-5 working days, and worldwide within 5-7 working days, after despatch. Note, this time frame can be longer.


We must allow delivery service an extra 20 working days for EU, and 25 working days for rest of world, before we can take further action, in the rare event of lost delivery.

Please note that we are a small manufacturing business. Officially we work Mon-Thurs (excluding public holidays). We are closed Friday - Sundays. If away for longer periods we will generally provide notice on calendar.

Before purchasing any Customduo product please ensure that you have read and accept our terms.

(BREXIT)  We are shipping to the EU as normal.  We generally post the next working day. However, delivery to EU is very slow at the moment (allow 30 working days). Sorry, this is beyond our control, and thanks for your patience.


Import charges may apply to international orders (a few EU customers have experienced import charges due to BREXIT. Ireland and Belgium seem to be the hottest on this!).
