London Fire Commissioner Andy Roe said: "Today, as we mark the fourth anniversary of the Grenfell Tower fire, we remember the 72 people who lost their lives.
"Our thoughts remain with their families and loved ones, those who survived and the Grenfell community as a whole.
"They will never be forgotten by the Brigade and we will never stop striving to further improve our service to London’s communities to help prevent such a tragedy from happening again."
