Money saving expert Martin Lewis says the 80% rise in the energy price cap is "hideous but NOT a surprise". The rise is set to send the the average household's yearly bill from £1,971 to £3,549 from October.
The cap will come into effect for around 24 million households in England, Scotland and Wales on default energy tariffs on October 1, and will remain in place until December 31, when it will be adjusted again. Read live reaction to the announcement here.
Martin Lewis said: "I've been accused of catastrophising about the energy hikes that have now come true. Yet let me be plain, 'doom-mongering' or not. More help is desperately needed for poorest or people will die this winter due to unaffordability of an 80% SO FAR energy price cap hike."
