Heathrow Airport's Terminal 3 car park was temporarily closed following a fire caused by a vehicle, reportedly an electric car, around 9 am, which destroyed one car and damaged two others.

Firefighters responded swiftly with four fire engines and approximately 25 personnel, bringing the fire under control by 10:06 am, with no injuries reported.

The cause of the fire is currently under investigation, and authorities are managing the incident and its aftermath.

The fire caused significant disruption, including the closure of the southbound M4 spur from Junction 4 and the M25 J14, leading to traffic congestion and rerouted buses away from Terminal 3.

Travel to Heathrow was heavily affected, with delays, long queues, and diverted bus routes, complicating passenger movement.

Footage from the scene shows intense orange flames and thick grey smoke emanating from the structure, highlighting the severity of the fire.

Adding to the chaos, a major crash involving a car and a lorry occurred on the M25 at Junction 14 early in the morning, resulting in one person being hospitalized and further delays, with the road expected to remain closed until mid-afternoon.

Buses serving Heathrow, including the 724 route operated by Arriva Herts and Essex, were affected, with some terminating at Terminal 5 due to the incident.

This fire incident follows a previous major disruption at Heathrow on March 21, 2025, when a fire at a nearby electricity substation led to the airport's closure until 6 pm, affecting over 270,000 passengers.

The earlier incident on March 21 also caused significant disruption, highlighting ongoing vulnerabilities and the airport's history of major incidents.

Emergency services responded promptly, though no further details on injuries or the exact cause of the fire have been disclosed.

The fire was caused by a vehicle, reportedly an electric car, igniting around 9 am, resulting in the destruction of one vehicle and minor damage to two others.
