At Critical Labs UK, we aim to provide a clear, professional, and transparent shipping experience. This Shipping Policy explains how orders are processed, dispatched, delivered, and handled in the event of delays or delivery issues.
Order Processing
Orders are reviewed and processed during our normal business hours. Processing times may vary depending on product availability, order verification, payment confirmation, weekends, public holidays, and other circumstances beyond our control.
Once an order has been processed and dispatched, customers may receive confirmation containing the relevant delivery information where applicable.
Delivery Times
Estimated delivery times are provided for guidance only and are not guaranteed. Delivery may be affected by:
- Courier or postal-service delays
- Public holidays and weekends
- Severe weather
- Incorrect or incomplete delivery information
- Customs or regulatory procedures
- Unexpected logistical disruptions
We recommend ensuring that all delivery information supplied at checkout is accurate and complete.
Tracking
Where tracking is available, relevant tracking information may be provided after dispatch. Customers should use the tracking information supplied to monitor delivery progress.
Tracking updates can occasionally take time to appear after an item has entered the carrier’s network.
Delivery Address
Customers are responsible for providing accurate delivery information at checkout.
Critical Labs UK cannot be held responsible for delays, failed deliveries, or additional costs resulting from incorrect, incomplete, or outdated address information supplied by the customer.
Delayed Deliveries
Although we work to minimise delays, delivery times can be affected by circumstances outside our control.
If your delivery appears to be delayed, please contact our support team with your order reference so that the matter can be reviewed.
Damaged or Incorrect Packages
If your package arrives visibly damaged, incomplete, or appears to contain an incorrect item, please contact our support team as soon as reasonably possible.
Where appropriate, photographic evidence or other relevant information may be requested to assist with investigating the issue.
Lost Deliveries
If a shipment is confirmed as lost during transit, we will review the circumstances and work with the relevant delivery provider where appropriate.
Resolution options may depend on the circumstances of the shipment, carrier procedures, and applicable consumer-protection requirements.
International & Cross-Border Shipping
Customers are responsible for ensuring that any product they order is lawful to purchase, possess, receive, or import in their jurisdiction.
Shipping availability may therefore vary according to destination, product category, applicable laws, customs requirements, and regulatory restrictions.
Critical Labs UK does not encourage customers to circumvent customs procedures, import restrictions, prescription requirements, or other applicable laws.
Age & Legal Requirements
Certain products may be subject to age restrictions, prescription requirements, licensing rules, or other legal controls.
Customers are responsible for complying with all applicable laws and regulations in their jurisdiction. Where legally required, appropriate verification may be requested before an order can be processed.
Contact Us
If you have a question regarding shipping, delivery, or an existing order, please contact our support team through the official Critical Labs UK contact channels.

Important Notice
Shipping availability, delivery estimates, product restrictions, and applicable requirements may change. This policy should be read together with our Terms & Conditions, Privacy Policy, and other applicable website policies.
