Around 150 Firefighters Battle Large-Scale Fire in London

Explosions were reported, and thick smoke filled the sky as emergency crews raced to contain the fast-moving blaze at a warehouse in west London.

Smoke warnings, travel disruption, and an escalating response defined the scene as a fire tore through a Southall warehouse, affecting most of the building.

The large fire in Middlesex Business Park, west London, prompted a significant emergency response on the morning of November 25, 2025, as the London Fire Brigade battled a major incident in Southall.

Crews were called to the blaze just before 8:55 a.m. on Bridge Road, where a two-storey warehouse and adjoining retail space had caught alight.

According to the brigade, the fire spread rapidly, with about three-quarters of the structure engulfed in flames. Witnesses in the area reported hearing "huge explosions," while thick smoke billowed into the sky, prompting public health warnings.

The operation escalated throughout the morning. What began with 70 firefighters soon increased to approximately 150 personnel and 25 fire engines, as teams from Southall, Heston, and Ealing responded.

The brigade described it as a "protracted incident," noting that firefighting operations would continue throughout the day.

In a post on X, the London Fire Brigade urged residents to keep doors and windows closed due to the heavy smoke. Those living or working nearby were advised to take precautions as the situation unfolded.

Authorities also warned that traffic in the surrounding area would likely be affected, with emergency vehicles and road closures expected to cause significant disruption.

The exact cause of the fire has not yet been established, and no information has been released regarding injuries or potential damage beyond the affected structure. Fire crews are expected to remain at the scene for several hours as they work to fully extinguish the blaze and investigate its origin.
