Rules & entry requirements
All connecting passengers must pass security
All connecting passengers must pass through security at Heathrow before continuing their journey. Large electronic devices and liquids up to 2 litres can remain in your cabin bag at connection security, but always follow staff instructions.

International-to-domestic connections require UK immigration first
Passengers connecting from an international flight to a UK domestic flight must clear UK immigration/passport control before security, in addition to the normal security screening.

Separate tickets = full arrival procedure
If you booked separate tickets you are not a connecting passenger: you must go through immigration, collect your baggage, check in again and re-enter security for your next flight. Allow extra time for these steps; Heathrow also recommends staying airside within the airport during a connection.
