The Metropolitan Police has submitted its final investigation file into the Grenfell Tower fire to the Crown Prosecution Service (CPS).

Twenty companies and organisations as well as 54 individuals could face criminal charges, the force said. These include corporate manslaughter, gross negligence manslaughter, health and safety offences, fraud and fraud-related offences and misconduct in public office.

The Met described the case into the tower block fire in North Kensington, west London, as one of the “most complex investigations ever undertaken by any UK law enforcement agency”.

A public inquiry in 2024 found the fire, on 14 June 2017, was avoidable. Seventy-two people died in the blaze.

The Met said it had spent £150m on Operation Northleigh – its investigation into the fire – which has examined the actions of 15,000 people across 700 organisations.
