This is our standard next day service. Order before 8pm Monday - Friday or 2pm Sunday for delivery next day. Unlike other services, if you order on a Friday your parcel will be delivered on a Saturday. Deliveries take place up until 8pm. No deliveries take place on a Sunday or Bank holiday.
If a mobile number is provided you will receive a text message from the courier confirming that your parcel is out for delivery, and also when it is delivered. This will also be confirmed by email. You will also receive a tracking number to track your parcel online. This mobile number will
not be used for anything other than to ensure your parcel reaches you smoothly.
