National Grid Investigation Underway Over Heathrow Airport Fire

Pomerantz LLP is investigating claims of securities fraud against National Grid plc (NYSE: NGG) on behalf of investors. The investigation concerns the company's knowledge of a fault at an electrical substation that caused a fire and shut down Heathrow Airport in March 2025. National Grid allegedly knew about the problem since 2018 but failed to fix it. Investors are advised to contact Danielle Peyton at [email protected] or 646-581-9980, ext. 7980.

Investors in National Grid plc (NGG) are being urged to contact Pomerantz LLP, a leading securities fraud law firm, following an ongoing investigation into potential violations of federal securities laws. The investigation centers around the company's knowledge of a fault at an electrical substation in Hayes, Hillingdon, London, which caused a fire and shut down Heathrow Airport in March 2025.

According to the investigation, National Grid was aware of the problem since 2018 but failed to fix it. On March 20, 2025, a fire at the substation led to Heathrow Airport shutting down, causing significant disruptions and financial losses. The incident resulted in the cancellation of more than 1,000 flights and affected around 200,000 passengers [2].

Investors who lost money due to this incident are advised to contact Danielle Peyton at [email protected] or 646-581-9980, ext. 7980, to inquire about potentially pursuing claims to recover their losses. Pomerantz LLP has a proven track record in handling complex securities litigation and has recovered billions of dollars for investors and consumers [1].

The investigation is ongoing, and the full extent of National Grid's liability is yet to be determined. However, the incident has raised concerns about the company's responsibility for maintaining the resilience of critical national energy infrastructure. The National Energy System Operator (NESO) has stated that the incident was caused by a known fault at the substation, which was not repaired despite being identified in 2018 [2].

Investors are urged to stay informed about the developments in this case and to consider their options for participating in any potential class action lawsuit. The investigation is a reminder of the importance of corporate responsibility and the need for transparency in the management of critical infrastructure.
