Some products are not kept in stock and are ordered from the manufacturer after your purchase. These products state the lead times at the top of the product pages. By default, orders containing items with different lead times will be despatched together based on the longest lead time.

Delivery Cut Off Times

The deadline for same-day despatch is 4pm, Monday to Friday. This deadline may not apply if we are unusually busy, if your order is unusually large, or if the carrier's vehicle has reached its weight limit.
