Orders placed before 3pm are dispatched same day. Orders placed after 3pm will be treated, for the purposes of delivery, as having been placed the next working day.
Working days are defined as Monday – Friday (excluding bank and public holidays) – therefore any orders placed after 3pm on Friday will not be processed until Monday.
The majority of deliveries require a signature to confirm receipt. If a signature cannot be obtained, the carrier may ask a neighbour to sign for the delivery. Deliveries that require a signature will not be left if a signature cannot be obtained.
If the carrier leaves the delivery with a neighbour or at your local post office, they will leave a card for you telling you where it is. You may, when placing your order online, specify a different delivery address than your payment address if this is more convenient for you.
All delivery timescales are approximate and subject to availability. The precise timing of a delivery cannot be specified.
All Signed For services are insured up to the value of £50. We recommend choosing the Special Delivery option for all orders over £50 as this covers goods up to £500 and is guaranteed the next working day delivery by 1pm.
