A damning report on a deadly London high-rise fire said Wednesday that decades of failures by government, regulators and industry turned Grenfell Tower into a “death trap” where 72 people lost their lives.

The years-long public inquiry into the 2017 blaze concluded that there was no “single cause” of the tragedy, but said a combination of dishonest companies, weak or incompetent regulators and complacent government led the building to be covered in combustible cladding that turned a small apartment fire into the deadliest blaze on British soil since World War II.

The inquiry’s head, retired judge Martin Moore-Bick, said the victims’ deaths were all avoidable, and “those who lived in the tower were badly failed over a number of years” by multiple people and organizations.

“All contributed to it in one way or another, in most cases through incompetence but in some cases through dishonesty and greed,” he said.

While the report may give survivors some of the answers they have long sought, they face a wait to see whether anyone responsible will be prosecuted. Police will examine the inquiry’s conclusions before deciding on charges.

The fire broke out in the early hours of June 14, 2017, in a fourth-floor apartment and spread up the 25-story building like a lit fuse, fueled by flammable cladding panels on the tower’s exterior walls.

The tragedy horrified the nation and raised questions about lax safety regulations and other failings by officials and businesses that contributed to so many deaths.

“How was it possible in 21st century London for a reinforced concrete building, itself structurally impervious to fire, to be turned into a death trap?” asked the report.

It concluded: “There is no simple answer to that question.”

Grenfell Tower, built from concrete in the 1970s, had been covered during a refurbishment in the years before the fire with aluminum and polyethylene cladding — a layer of foam insulation topped by two sheets of aluminum sandwiched around a layer of polyethylene, a combustible plastic polymer that melts and drips on exposure to heat.

The report was highly critical of companies that made the building’s cladding. It said they engaged in “systematic dishonesty,” manipulating safety tests and misrepresenting the results to claim the material was safe.

It said insulation manufacturer Celotex was unscrupulous, and another insulation firm, Kingspan, “cynically exploited the industry’s lack of detailed knowledge.” It said cladding panel maker Arconic “concealed from the market the true extent of the danger.”

The combustible cladding was used on the building because it was cheap and because of “incompetence of the organizations and individuals involved in the refurbishment” – including architects, engineers and contractors — all of whom thought safety was someone else’s responsibility, the report said.

The inquiry concluded the failures multiplied because bodies in charge of enforcing Britain’s building standards were weak, the local authority was uninterested and the “complacent” Conservative-led U.K. government ignored safety warnings because of a commitment to deregulation.

The inquiry has held more than 300 public hearings and examined around 1,600 witness statements. An initial report published in 2019, looking at what happened the night of the fire, criticized the fire department for telling residents to stay in their apartments and await rescue. The advice was changed almost two hours after the fire broke out, too late for many on the upper floors to escape.

London Fire Brigade came in for further criticism for a “chronic lack of effective management and leadership.” The report said firefighters were not adequately trained to deal with a high-rise fire and were issued with old communications equipment that didn’t work properly.

The Grenfell tragedy prompted soul-searching about inequality in Britain. Grenfell was a public housing building set in one of London’s richest neighborhoods — a stones’ throw from the pricey boutiques and elegant houses of Notting Hill — and many victims were working-class people with immigrant roots. The victims came from 23 countries and included taxi drivers and architects, a poet, an acclaimed young artist, retirees and 18 children.

The report said the inquiry had “seen no evidence that any of the decisions that resulted in the creation of a dangerous building or the calamitous spread of fire were affected by racial or social prejudice.”

In the wake of the fire, the U.K. government banned metal composite cladding panels for all new buildings and ordered similar combustible cladding to be removed from hundreds of tower blocks across the country. But it’s an expensive job and the work hasn’t been carried out on some apartment buildings because of wrangling over who should pay.

The report made multiple recommendations, including tougher fire safety rules, a national fire and rescue college and a single independent regulator for the construction industry to replace the current mishmash of bodies.

The ruined tower, which stood for months after the fire like a black tombstone on the west London skyline, still stands, now covered in white sheeting. A green heart and the words “Grenfell forever in our hearts” are emblazoned at the top.

Police are investigating dozens of individuals and companies and are considering charges, including corporate and individual manslaughter. But they say any prosecutions are unlikely to come before late 2026.

“I can’t pretend to imagine the impact of such a long police investigation on the bereaved and survivors, but we have one chance to get our investigation right,” said Deputy Assistant Commissioner Stuart Cundy of the Metropolitan Police.

Sandra Ruiz, whose 12-year-old niece, Jessica Urbano Ramirez, died in the fire, said that “for me, there’s no justice without people going behind bars.”

“Our lives were shattered on that night. People need to be held accountable,” she said. “People who have made decisions putting profit above people’s safety need to be behind bars.”
