The fire at Luton Airport’s car park was found to have started accidentally, most likely from an electrical fault or component failure in a moving diesel vehicle. Investigators said it was not believed to be an electric vehicle.

What investigators concluded

A joint investigation by Bedfordshire Police and Bedfordshire Fire & Rescue Service said the blaze most probably began in the engine bay while the vehicle was moving, then spread to other cars.

What was ruled out

The report specifically rejected online claims that the fire started with a battery-powered vehicle, saying the car involved was diesel and not a mild hybrid, plug-in hybrid, or electric vehicle.

Why it spread so fast

Once the fire started, it spread rapidly to nearby parked vehicles and across the multi-storey structure, which is why it became such a major incident.
