Insulate Britain is an environmental activist group, founded by six members of the global environmental movement Extinction Rebellion in 2021. Their methods slightly differ from that of Extinction Rebellion, but they share the same overall target: to reduce the rate of climate change. The group began hosting both online and in-person events in July 2021, also raising money for direct action. Founded with the aim of demanding insulation across the United Kingdom, the group laid out two specific demands for its September 2021 protests. The first is that the British government fund insulation of all social housing by 2025, and the second is that, by the end of 2021, the government should create a plan to fund retrofitting of insulation of all homes in Britain by 2030.
