The force said it has now submitted all its files to the Crown Prosecution Service to allow it to make charging decisions in relation to the June 2017 blaze.
The files of evidence, which relate to 20 companies and organisations and 54 individuals, was a “milestone moment” in a “truly enormous” investigation, police said.
Seventy-two people died and more than 70 were injured after a fire broke out in the 24-storey Grenfell Tower block of flats in North Kensington, West London.
The Met said in a statement: “The 20 files relate to 20 companies and organisations and 54 individuals.
“They ask the CPS to consider charges including corporate manslaughter, gross negligence manslaughter, health and safety offences, fraud and fraud-related offences and misconduct in public office.
“The CPS has committed to making the charging decisions before the 10th anniversary of the fire in June 2027.”
Cllr Elizabeth Campbell, Leader of Kensington and Chelsea Council, said:
“This is a significant moment for all bereaved family members, survivors, residents and all those affected by Grenfell. Our thoughts remain first and foremost with them and the 72 people who lost their lives. We hope that the legal process gives people the answers they seek.
“We have accepted the Council’s failings, and our commitment to candour, openness, and accountability has not changed. We will continue our focus on meeting the commitments we made following the Grenfell Tower Inquiry.
“The Council has cooperated fully with the Metropolitan Police investigation, just as we fully cooperated throughout the separate Grenfell Tower Inquiry which concluded in 2024, and we will continue to provide any information or assistance asked of us.”
