In England, the current Day 2 test standard will change from PCR to lateral flow from 4am on Sunday (24 October).
All arrivals, including those who are fully vaccinated against Covid-19, will still be required to complete a Day 2 test.
Tests can be delivered to travellers’ homes, or completed at any of the firm’s 24 regional and airport testing centres.
Results are confirmed in 25 minutes, and will be authenticated once travellers upload a picture of their completed test and their passport number to the ExpressTest app.
