British Prime Minister Liz Truss said Thursday that her government will cap domestic energy prices for homes and businesses to ease a cost-of-living crisis that has left people and businesses across the UK facing a bleak winter.

Truss told lawmakers in Parliament that the two-year ‘energy price guarantee’ means average household bills will be no more than £2,500 ($2,872) a year for heating and electricity. Bills had been due to rise to £3,500 ($4,000) pounds a year from October, triple the cost of a year ago. Bills are skyrocketing because of Russia’s invasion of Ukraine and the economic aftershocks of Covid-19 and Brexit.
