Addressing the press, a man who lives just a few metres from the high-rise building described the scene as a "real inferno".
Meanwhile, this comes after a major incident was declared in London on Tuesday as a spate of wildfires added pressure to the fire service. The London Fire Brigade said that it had deployed dozens of fire engines to several fires in and around the city.
The record-breaking heat also led to train cancellations in the country. Videos and photos from across the nation surfaced online, which showed the damage the record temperature caused. While one video showed houses in a village outside East of London damaged by a massive fire, another showed a forest burning on the side of a highway.
