Flight radars show how the concerned captain circled several above the English Channel while burning and dumping fuel before bringing the Boeing 777-300ER back to Heathrow to land.
Shortly after leaving Heathrow, a warning light appeared, alerting the pilot that the cargo hold door was not shut securely.
According to the Boeing website, the aircraft can carry up to 47,890 gallons in its fuel tank, which can cost upwards of £60,000 to refuel based on current fuel prices.
Webcam footage from Airlivenet showed the plane as it landed back at Heathrow.
There were 344 passengers and 20 crew on board, who were taken off the flight while engineers battled to identify the problem.
Flight Lieutenant Pratana Patanasiri, Vice President Aviation Safety, Security and Standards Department, said that the plane was at 8000 feet before the incident when the light appeared.
He said: “The sensor for the cargo hold door look system showed an irregularity.
“Flight engineers took about two hours to check the whole aircraft. They found the notification light issue, there were no hazardous irregularities.
