Passports, where there are notes on the issuance of transit visas at the border, we saw, but with tourists on this issue did not communicate. You can see the information on the official website of the British Embassy.

The official website of the British Embassy says that if there is an air ticket for departure within 24 hours and the proper documents for the final point of travel (visa to the final destination), stay on the territory of the country without a visa is permissible. However, the very fact of an unhindered continuation of the journey remains at the discretion of the visa officer.

According to the experienced, questions can arise more quickly from representatives of low-costers: the rules for such airlines can be prescribed that a passenger is required to have a visa or the right of visa-free entry (not transit) to the country of destination. There are cases when a traveler without a British visa is simply not put on a flight of such an airline. Other airlines, for example, "British Airways" (British Airways), do not express such claims.
