From the AIP:
"Diversion Procedure – Airline and other operators are requested to resist filing London Heathrow as an alternate. However, where this is unavoidable, they are required to have made arrangements for ground handling with an airline from the appropriate terminal. It should be noted that during the night, ground handling facilities are very limited without prior arrangement. Nothing in this procedure shall, however, prevent an aircraft that has declared an emergency from landing."
