The video shows the explosion followed by a towering column of smoke, with sparks scattering in all directions.

It took place at the electrical substation in Nestles Avenue on Thursday evening but caused travel chaos at Heathrow Airport for days to come.

Over 1,300 flights were cancelled and at least 200,000 passengers impacted.

Flights have since resumed following hours of closure after the blaze occurred late on Thursday evening.

The house which caught the footage is believed to be about 1,500 feet (500 m) from the substation.
