The Fire Safety Act (2021) received Royal Assent on 29 April 2021, though it is still to come into force. You can read about the Fire Safety Act on the government website. The Building Safety Bill, in its current form, was introduced to the House of Commons on 5 July 2021.
Both the Fire Safety Act and the Building Safety Bill intend to make sure that residents of high-rise buildings feel safer in their homes by significantly reducing fire risks. They are a response to the Grenfell Tower tragedy – to stop such an event from ever happening again and minimising fire risks to make sure that high-rise buildings are managed properly.
