The local borough pledged to carry out a full investigation into the fire.
Prime Minister Theresa May ordered a full public inquiry, saying that people "deserve answers" to why the fire was able to spread as quickly as it did.

In July 2017, the government offered an amnesty to those who had been illegally sub-letting and a one-year immigration amnesty to those who came forward with information, though did not offer a full guarantee against deportation.
On 31 August 2017 Immigration Minister Brandon Lewis announced that the deadline to register for the one-year immigration amnesty for displaced undocumented residents of Grenfell Tower was to be extended by three months to 30 November 2017.
Sir Martin Moore-Bick (who leads the public inquiry) wrote to the Prime Minister asking her to consider the long term future for these residents beyond their value as witnesses for the inquiry.
These views were echoed by campaign groups BMELawyers4Grenfell and Justice4Grenfell.

On 16 September 2019 it was reported that London Fire Brigade as a body have been interviewed by Metropolitan Police under caution in respect of the Health and Safety at Work etc.
Act 1974.
In a press statement, LFB Commissioner Dany Cotton said the Brigade had been subject to police investigation from just after the fire; hundreds of officers had given voluntary police interviews; and LFB would continue to assist investigators.

Leilani Farha argued that the failings of Grenfell Tower were a breach of residents' human rights, because they were not sufficiently involved in the way the building was developed, notably safety issues, before the fire and are not sufficiently involved in the investigations after the fire.
