The energy crisis poses a devastating challenge for many this winter. Though the recent announcement of the Government's Energy Price Guarantee has taken a small step in the right direction by setting the typical household's bills at £2,500, there are many groups still at severe, potentially life-threatening risk. One such group includes those with a disability who will likely pay more than the average £2,500.

In response to the shocking Russian invasion of Ukraine, we are expecting the Prime Minister to say more next week about the UK's energy strategy to free ourselves from Putin's "malign influence". Kwasi Kwarteng, among others, has debunked the idea we can drill our way to energy independence. Fantasies of fracking the UK countryside play into Putin's hands by distracting from real solutions. So here are seven things we think the Prime Minister should announce, building on the UK's ambitious Net Zero Strategy but with the much greater urgency the crisis has shown is required.
