Shipping Policy

UK delivery is sent on Royal Mail Tracked 24. Orders under £150 are charged a flat £4.99. Orders of £150 and over qualify for free Tracked 24 delivery.

You can optionally upgrade to Royal Mail Special Delivery Guaranteed by 1pm for an additional £5.00. The applicable rate is always shown at checkout before you complete your order.

Orders placed before 2pm on a working day (Monday to Friday) are dispatched the same day. Orders placed after 2pm, at weekends or on public holidays are dispatched the next working day. Dispatch begins only once payment has been received and confirmed.

Orders are sent on a tracked UK delivery service. Estimated delivery times are indicative and may vary due to courier handling, location or circumstances outside our control.

Where tracking is available, we will provide tracking details by email once your order has been dispatched.

You are responsible for providing a complete and accurate delivery address at checkout. We cannot be held liable for orders delayed, lost or delivered incorrectly as a result of an incomplete or inaccurate address. Once an order has been dispatched we are unable to redirect it to a different address.

All orders are dispatched in discreet, secure packaging.

If your tracking shows no movement for 48 hours, or it has been 3 working days since dispatch with no delivery, contact us at support@zyrexlab.com with your order number and we will open an enquiry with Royal Mail. A parcel is generally treated as lost once Royal Mail confirms it cannot be located. If your order arrives damaged, please contact us within 14 days of delivery with photographs so we can arrange a replacement or refund for verified issues.
