However, there may be other people who were in there on the night that others were not aware were there.
"In circumstances where foam plastic insulation is permitted, the insulation must meet stringent fire performance testing to limit the amount of smoke produced and slow the spread of flame, or the insulation must be protected by non-combustible material", Cripps said in an email.
The new exterior cladding used in a renovation on London's Grenfell Tower may have been banned under United Kingdom building regulations, two British ministers say as police continue their investigation into the inferno that killed at least 58 people. "The bodies have been taken to a morgue, but more bodies remain in the building".
Survivors of the Grenfell Tower blaze are being given just £10 to live on by the council, a volunteer has said.
"In the wake of (the) Grenfell fire we have to recognise that something has gone badly, badly wrong in this country, that predominantly poor people die in a towering inferno because possibly in the long term (there had been a) lack of public investment", Mr Corbyn told ITV's Peston on Sunday programme.
Cripps said the Ontario Building Code applies to the construction of new buildings and renovations of existing structures.
"The work to search the building is challenging, but naturally could never be done quickly enough for those now having to live with the uncertainty of knowing where their loved ones are".
As NPR's Merrit Kennedy reported, the Grenfell Tower fire has aroused the ire of those who feel it was caused by corporate malfeasance and who feel Prime Minister Theresa May's government is not doing enough to respond. "Sadly we do not expect there to be any survivors", Cundy said. The conditions due to the fire damage verge on indescribable, which is why this will be such a lengthy operation taking weeks to complete. Stuart Cundy said in a statement.
Hundreds of people descended on community centres and churches following the disaster that left at least 58 people dead, donating food, clothes and nappies while others raised nearly £3m for the victims on websites such as JustGiving. This year, however, it is hard to escape a very sombre national mood.
He told reporters that the investigation's "absolute priority" is to establish the identities of those inside the building.
Mr Cundy also appealed to anyone who may have escaped from the building, but has not yet come forward, to make themselves known. "We need to find out precisely what cladding was used and how it was attached".
The move came after the Prime Minister met with residents near the site of the fire that ripped through the residential block in the early hours of Wednesday morning, killing at least 30 people.
The Government has announced it will give the residents of Grenfell Tower at least £5,500 per household as part of its pledge to spend £5m helping them back onto their feet.
There was a large police presence as Mrs May met a group of victims, residents, volunteers and community leaders at St Clement's Church close to the scene of the horrific blaze on Friday afternoon.
Alongside both police and fire investigations into the blaze, she has promised to set up a public inquiry.
