⏱ Dispatch & Delivery Timing
We aim to dispatch all in-stock orders promptly, but delivery depends on both when you order and which service you select.
- UK orders: placed by 2:00 PM Monday–Friday are usually dispatched the same day.
- International orders: placed by 2:00 PM Monday–Thursday are usually dispatched the same day.
Orders placed after these times are processed the next working day. This means delivery may occur the following day or later, depending on the courier and service selected.
Once dispatched, your chosen delivery service determines how quickly your parcel arrives:

- Premium services (e.g. Royal Mail Special Delivery or DHL by Noon) offer guaranteed delivery windows.
If your order is time-sensitive, we strongly recommend choosing a guaranteed service or contacting us before ordering to confirm availability.
Please note: For logistical reasons, we may occasionally adjust the delivery method selected at checkout. For example, smaller items may be better suited to letterbox-friendly packaging or may be at greater risk of delay or loss via certain services. We actively monitor courier and postal service disruptions—including strikes and delays—and may modify shipping arrangements to help ensure timely and secure delivery.

We always aim to dispatch promptly, but delivery times may be affected by:
