Police investigating the 2017 Grenfell Tower fire in north Kensington, west London, have submitted files of evidence on 20 companies and 54 individuals to prosecutors, marking a significant step toward potential charges in the case. The Metropolitan Police described the handover as a milestone in one of the most complex investigations ever undertaken by a UK law enforcement agency. The Crown Prosecution Service (CPS) has indicated it aims to make charging decisions before the 10th anniversary of the disaster on June 14, 2027.
The fire, which occurred shortly before 1 a.m. on June 14, 2017, resulted in 72 deaths and many injuries. A public inquiry concluded in 2024 that the tragedy was avoidable and pointed to decades of governmental failure alongside "systematic dishonesty" by companies whose combustible cladding and insulation materials contributed to the rapid spread of the fire. The inquiry specifically criticised firms including Arconic, Celotex, and Kingspan, accusing them of manipulation and dishonesty in supplying flammable products for the building’s exterior. Local authorities such as the Royal Borough of Kensington and Chelsea (RBKC) council and the Kensington and Chelsea Tenant Management Organisation were also criticised for their roles.
The police investigation, known as Operation Northleigh, began shortly after the fire and involved an exhaustive review of more than 15,000 people and 700 organisations connected to Grenfell Tower. Detectives conducted a detailed forensic examination over 14 months at the site, including an intensive fingertip search and analysis of approximately 15 tonnes of debris from each floor. The inquiry compiled over 14,700 witness statements, amassed 165 million electronic documents, and collected more than 27,000 physical exhibits—including cladding, insulation, doors, and other building components—all securely stored. In preparation for possible trials, scale replica parts of the tower are being constructed at a cost of £2 million.
Potential offences under consideration include corporate manslaughter, gross negligence manslaughter, health and safety violations, fraud-related offences, and misconduct in public office. Among the organisations referred to the CPS are the RBKC council and the Ministry of Housing, Communities and Local Government (MHCLG), with the council facing allegations of corporate manslaughter, breaches of the Health and Safety at Work Act 1974, and violations of the Regulatory Reform (Fire Safety) Order 2005. The MHCLG is also under investigation for potential health and safety breaches.
Senior police officials underscored the investigation’s scale and complexity, attributing the length of the inquiry to the need for meticulous evidence gathering to ensure sound prosecutions. Kevin Southworth, deputy assistant commissioner at the Metropolitan Police, acknowledged the impact of the wait on victims’ families but emphasized that the thoroughness was necessary to present the strongest possible case.
The CPS’s Frank Ferguson highlighted the emotional toll the investigation has taken on bereaved families and survivors, affirming the CPS’s commitment to a careful and independent review of the evidence before proceeding with any charges.
Representatives of bereaved families and survivors, including Grenfell United, have urged authorities to avoid further delays, stressing the importance of justice for those who lost loved ones. Politicians have also called for swift action ahead of the upcoming anniversary, with some expressing disappointment at how long the process has taken.
Local council leaders have accepted failings identified in the inquiry and reiterated their commitment to transparency and accountability moving forward. Meanwhile, government officials have pledged to respond with diligence as investigations continue.
