Holidaymakers flying from Heathrow Airport can now get rapid one-hour Covid-19 tests before they fly.
The private test will cost £80 per passenger and aims to give a result within one hour, before travellers board their flight.
Those who want to make use of the tests will need to pre-book a slot online before they travel to the airport.
At the moment the tests are being trialled in Terminal 2 and Terminal 5, for passengers who are flying to Hong Kong and Italy.
The aim of the test is to help people travelling abroad when proof of a negative result is required on arrival. At the moment, both Hong Kong and Italy require arrivals to provide proof of a negative Covid-19 test.
Italy had recently introduced the new requirement for number of countries including the UK.
During the pandemic, countries have imposed new restrictions and entry requirements, and the FCDO's travel advice has been subject to change, especially to destinations where there are fears of rising numbers of coronavirus cases.
Countries have been added or removed from the list of the UK's travel corridors, which determine if Brits will need to quarantine for 14 days when returning from a specific destination.
Earlier this month the government launched a new taskforce with the aim to look into potential ways that the current 14-day quarantine rules could be cut.
This includes looking at whether airport testing could be the solution, as well as other alternatives such as self-isolating before you are due to travel.
At the moment, the new venture is in early stages, so the existing 14-day quarantine rules continue to apply.
Holidaymakers will be able to take a Covid-19 test at a certified lab, upload the results on their phone and then fill out any additional health screening questionnaires required by their destination.
The CommonPass, which will be on an app, will confirm that you have met entry requirements and generate a QR code that can be scanned by airlines and border control officials.
The pass is being tested on flights between London Heathrow and New York on board United Airlines flights, as well as a route between Hong Kong and Singapore operated by Cathay Pacific Airways.
