Direct Airside Transit Visa (DATV) is not required for passengers holding a valid visa issued by Australia, Canada, New Zealand or the United States when transiting at London Gatwick Airport (LGW), London Heathrow Airport (LHR) or Manchester Airport (MAN) and the passenger's next destination is not Ireland. Passenger must hold an onward flight, correct documentation for their destination and depart the same calendar day. E-visas or e-residence permits are not acceptable unless the airline is able to verify it with the issuing country.

Digital driving licences issued by Ukraine (DIIA) may also be recognised once verification tools have been made available and deployed by Ukraine.

но хз, сделали наши verification tools или нет
меня не тормозили, повода проверить не было 🙂
