A major fire tore through a high voltage electrical substation near Heathrow Airport late on March 20, causing significant disruption at one of the world’s busiest airports. The blaze knocked out power and grounded 1,350 flights, leading to chaos for passengers and airlines.
The London Fire Brigade (LFB) confirmed that the fire is now under control, but crews remain on site monitoring smouldering hotspots. The incident involved a transformer containing 25,000 litres of highly flammable cooling oil, prompting a large-scale emergency response.
During the fire, over 212 emergency calls were received. LFB deployed 10 fire engines, two Bulk Foam Units, and a High Volume Pump, with around 70 firefighters working in hazardous conditions to contain the blaze.
A 200-metre safety cordon was established around the site. As a precaution, 29 residents from nearby homes were evacuated, and 150 people were temporarily housed in a rest centre.
Deputy Commissioner Jonathan Smith praised the efforts of the emergency teams, stating: “Our firefighters worked tirelessly in challenging and hazardous conditions overnight to bring the fire under control as swiftly as possible. I thank all firefighters and Control officers for their courage and professionalism during very difficult circumstances.”
The Metropolitan Police initially investigated the fire due to its impact on critical infrastructure but have since ruled out foul play, handing the investigation back to the Fire Brigade. LFB Fire Investigation Officers, supported by scientific advisors, are now probing the exact cause of the blaze. Fire Safety Officers are also reviewing compliance with the Regulatory Reform (Fire Safety) Order 2005.
The Brigade will maintain a presence at the site to extinguish any remaining hotspots. The fire has raised urgent questions about the resilience of national critical infrastructure.
Authorities have pledged to keep the public informed as the investigation continues and recovery efforts progress. Passengers and local residents are advised to follow official updates from Heathrow Airport and the London Fire Brigade for the latest information.
