On July 2, 2025, a Reuters article titled "Preventable' National Grid failures led to Heathrow fire, findings say" reported on a fire that disrupted operations at London’s Heathrow Airport in March. The fire was caused by the failure of the UK power grid to maintain an electricity substation, according to an official report. The incident, which left thousands of travelers stranded, has prompted the energy regulator to initiate an investigation. In response, Ed Miliband, the UK Energy Minister, expressed deep concern, noting that the issue that led to the fire had been identified seven years ago but was not addressed by National Grid.

Following the publication of the report, National Grid American Depositary Shares (ADSs) saw a 5% decline in value on July 2, 2024.
