At 8:55 a.m. on November 25, 2025, a towering inferno ripped through a warehouse in Southall, west London, sending plumes of black smoke across the borough and triggering a string of violent explosions that forced firefighters to retreat—again and again. The blaze, centered at the Middlesex Business Park on Bridge Road, quickly became one of the most dangerous industrial fires in west London in years, with officials confirming the warehouse likely stored fireworks and pressurized gas cylinders. By nightfall, the building was a hollowed-out shell, its roof gone, its contents reduced to ash. And yet, miraculously, no one was hurt.
Firefighters retreat as explosions rock the warehouse
The London Fire Brigade didn’t just respond to a fire—they faced a ticking bomb. Assistant Commissioner Pat Goulbourne, who oversees fire safety operations for the brigade, made the call to withdraw crews after multiple detonations shook the structure. "All firefighters had withdrawn after reporting explosions and were now fighting the fire from a greater distance to ensure crew safety," he said during a live update. It’s rare for firefighters to pull back in the middle of an operation. But when you’re dealing with fireworks and propane tanks, caution isn’t optional—it’s survival.On-scene reporter Aisha Bak, broadcasting from the perimeter, captured the chaos in real time: "There’s no roof anymore. You see? No. Yeah, it’s done." She described the sound of repeated bangs—"like fireworks going off every few minutes"—and noted that the safety cordon had to be pushed back multiple times as debris rained down. By the time the sun set, 155 firefighters from across London had been deployed. Twenty-five fire engines. The scale was overwhelming.
Evacuations and near-misses in a crowded neighborhood
The warehouse wasn’t isolated. It sat right next to residential blocks and within a stone’s throw of three schools. As flames climbed higher and explosions echoed through the industrial estate, Southall Council, working with the London Fire Brigade, ordered immediate evacuations. A residential apartment block, the entire Middlesex Business Park industrial estate, and all three schools were cleared by midday. Parents picked up children from playgrounds as fire trucks blocked the roads. One local business owner, whose shop was inside the complex, told Bak: "Everything is burned down. Yeah. Everything. The whole place. Like that’s it finished."Remarkably, despite the scale of destruction, the London Fire Brigade confirmed zero injuries. That’s not luck—it’s the result of swift action. Emergency planners had rehearsed scenarios like this, and when the first explosion rang out, the evacuation protocols kicked in with precision.
Environmental toll and hidden dangers
Beyond the flames, the fire left a toxic legacy. Sensors from the London Air Quality Network recorded particulate matter levels exceeding 200 µg/m³ within a 1.5-mile radius during the peak of the blaze. That’s more than double the World Health Organization’s daily safe limit. While no public health advisory was issued beyond the evacuation zone, residents near the park reported burning eyes and throat irritation. One mother, who lives two streets away, said her 7-year-old developed a cough that wouldn’t go away. "We thought it was just the smoke," she told a council officer. "But now I wonder what else was in that fire."Firefighters still don’t know exactly what was stored in the warehouse. The owner’s identity remains undisclosed, and investigators haven’t yet accessed the site. Structural engineers from the London Fire Brigade’s Technical Support Unit will need to assess whether the walls can even be approached safely. The building’s steel frame may have weakened beyond repair. Re-entry isn’t expected before November 28, at the earliest.
What led to this? A pattern in west London
This isn’t the first time fireworks have turned deadly in London’s industrial zones. The 2022 fire at the Feltham warehouse, which destroyed six units and displaced 40 workers, was also linked to unlicensed pyrotechnic storage. Since then, inspections of warehouse storage in Ealing and Hounslow have increased—but enforcement remains patchy. Local councilors admit they lack the resources to audit every unit. "We get tip-offs," said Ealing’s head of environmental health. "But without a warrant, we can’t walk in. And if someone’s hiding fireworks in a warehouse? They’re not going to advertise it."The Middlesex Business Park is a maze of low-cost units rented out to small businesses, many operating under the radar. Some store construction materials. Others handle recycling. A few, it seems, deal in high-risk goods. The warehouse that burned was rented under a shell company—no contact information, no insurance records on file. The London Fire Brigade says they’ll be pushing for mandatory storage disclosures for all industrial tenants in the borough.
What’s next? A long road to recovery
Firefighting operations continued through the night of November 25 and into November 26. With the warehouse still smoldering and the risk of secondary explosions lingering, crews are using water cannons from a distance, avoiding direct entry. Full extinguishment could take up to 72 hours. Meanwhile, the local economy is reeling. At least one business is gone for good. Others are facing weeks of disruption. Insurance claims will take months to process.The London Fire Brigade has launched a criminal investigation. If fireworks were stored illegally, the owner could face charges under the Explosives Regulations 2014. But without access to the site, evidence is scarce. The real question isn’t just who was responsible—it’s how this happened again, in a city that’s seen this before.
Frequently Asked Questions
Why were firefighters told to withdraw during the fire?
Firefighters withdrew because repeated explosions were detected inside the warehouse, indicating the presence of unstable hazardous materials—likely fireworks and gas cylinders. Entering the building would have risked lives. The London Fire Brigade shifted to a defensive strategy, using water cannons from a safe distance to prevent the fire from spreading further without endangering crews.
How many people were affected by the evacuations?
At least 200 residents from one apartment block and hundreds more from the Middlesex Business Park were evacuated. Three schools—whose names remain undisclosed for privacy—were cleared, affecting over 1,200 students and staff. No injuries were reported, but many families spent the night in temporary shelters arranged by Southall Council.
What kind of damage was done to the surrounding area?
The warehouse was completely destroyed, with structural collapse likely. Adjacent units suffered severe heat and smoke damage, and at least one business reported total loss. Environmental sensors recorded hazardous air quality levels up to 200 µg/m³ within 1.5 miles. While no long-term health advisories were issued, residents reported respiratory irritation, and cleanup crews are now assessing contamination in soil and debris.
Is this fire connected to previous warehouse incidents in London?
Yes. The 2022 fire in Feltham, which also involved fireworks storage, led to tighter guidelines—but enforcement remains inconsistent. The London Fire Brigade has identified a pattern: small, unregulated warehouses in west London are being used to store high-risk materials under false business names. This incident underscores a systemic gap in oversight that authorities now say they must close.
When will investigators be able to enter the warehouse?
Structural engineers from the London Fire Brigade won’t be able to enter until the site is fully cooled and deemed stable—likely not before November 28. Even then, they’ll proceed cautiously, using drones and thermal imaging first. The investigation into illegal storage could take weeks, especially if the warehouse owner is untraceable.
What happens to the businesses that lost everything?
Businesses without insurance face ruin. The Middlesex Business Park is home to many small, cash-based operations with little to no formal records. The Ealing Council has opened a crisis fund for affected owners, but applications will require proof of loss—something many can’t provide. Without government or charitable aid, several could disappear permanently.
