Authorities are trying to determine if any criminal offenses were made by the building's managers, with accounts from residents indicating that it was for years a fire trap. But on the streets, there is anger over whether the block's renovation project purposefully did not include safety devices, such as sprinklers, or used banned flammable materials to clad the building and make it more attractive for neighbours in the upmarket Kensington and Chelsea region.
Some Grenfell residents had warned months ago fire safety issues at the tower meant that it was at risk of a "catastrophic" event.
Search and recovery crews have been working in the tower since last Wednesday's fire.
The revised death toll comes as images showing the burned-out interior of the London tower block are released.

British outlets said May struggled to offer support or leadership in the wake of the blaze, accusing her of lacking emotional intelligence and calling her "Maybot".
Public anger has been mounting over the British government's handling of the blaze, with Prime Minister Theresa May admitting that the response from authorities had not been good enough.
He said the group had spoken about their "demands and what we expect".
The meeting is unlikely to quell complaints that May has been slow to reach out to fire survivors, despite her announcement of a $6.4 million emergency fund to help displaced families.

The identification of the victims is proving very hard - which experts attribute to the extreme heat of the fire.
Cundy promised an "exhaustive" criminal investigation into the fire that would also look at a major refurbishment of the building completed previous year.
Officials are using dental records, fingerprints, DNA samples, tattoos and scars to try and positively identify victims.
