The inhabitants of the building organised the Grenfell Action Group, years ago.
They regularly pointed out problems with the building.
In 2013, they published part of a report, where they showed that the protection against fire was insufficient in the building.
 Regulations require that these materials are checked regularly.
According to the 2013 report of action group, there had been no such checks in the three years before the report.

When a building is on fire, people need to be able to get out quickly.
Usually, there are specially signalled escape lanes for this.
The action group pointed out that the escape lanes were not free, and people often parked their cars in such a way that the police was unable to get close to the building.

There had been various repairs and renovations in the building, from 2014 to 2016.
The company who was responsible for these works said that they were shocked, at what had happened, and that at the time the works had been done, regulations had been met.
