Cignpost ExpressTest said its new tests would be available for fully vaccinated international passengers arriving at Heathrow, Gatwick, Birmingham and Edinburgh airports.

The tests, priced £19.99, can be pre-ordered and collected at Heathrow’s T2, T3 and T5, as well as the three other UK airports.

Results will be confirmed within 25 minutes and authenticated by the passenger uploading a photograph of their test and passport number to the ExpressTest app.

Christian Corney, chief executive of Cignpost ExpressTest, said: “Since the government has made lateral flow tests mandatory for everyone arriving into the UK, we have looked at how we can make the testing process easy at every level.

“There’s a £1,000 fine for anyone who misses the two-day deadline to complete their test, so launching a click and collect option gives international travellers the reassurance that they’ve met their Covid testing requirement, rather than worrying about whether their tests have arrived at the hotel or guesthouse they are staying in.”
