Once you've received the kit, use the FCDO website to check when your destination country requires you to perform it. You only need an internet connection to be guided through the process, step by step - all the way to your result and any certification you need within 20 minutes. Easy!

Step 1: Buy

Buy your test online in advance - ideally at least 5 days before you’re due to fly out of the UK. We’ll send the kit to you within 48 hours.

Step 2: Register and get ready to go

When you’re ready, follow the simple and intuitive instructions in the kit to register the test online - making sure you're following the guidelines for your destination country [via the FCDO website](

Step 3: Take the test

Following the advice included, take the test using the swabs and the lateral flow device provided. It should only take a few minutes to do this.
