Investors in National Grid plc (NGG) are being urged to contact law firms to discuss potential claims following a significant drop in the company's stock price. The decline, which occurred on July 2, 2025, was attributed to a fire at an electrical substation owned by National Grid. The fire, which took place on March 20, 2025, resulted in the temporary closure of Heathrow Airport, causing widespread disruption.

According to a report published by the National Energy System Operator (NESO) in the UK, the fire was caused by a known fault at an electrical substation owned by National Grid. The company had been aware of the problem since 2018 but failed to rectify it. This oversight led to a catastrophic failure, causing the transformer to catch fire and resulting in the closure of Heathrow Airport for most of March 21, 2025 [3].

The incident caused National Grid's stock price to fall by $3.77, or 5.1%, to close at $70.61 per share on July 2, 2025 [1, 2]. Investors who suffered financial losses as a result of this event are being advised to contact the Law Offices of Howard G. Smith or the Law Offices of Frank R. Cruz to discuss potential claims [1, 2].
