Please note our offices and warehouses will be closed from 24th December until 2nd January 2025.
In-stock orders placed before 4:30pm on Friday 20th December should arrive before Christmas on a Next Working Day Delivery service. We are unable to guarantee this, however, as we rely on external couriers. Orders placed after this time will be processed and despatched as normal, but we cannot guarantee a pre-Christmas delivery. Any orders placed on Tuesday 24th December, or during the festive period, will be delivered in the first working days of the new year.
We recommend you place your order early, and look forward to serving you again in 2025.
