Eight million people receiving benefits and on low incomes will receive their £900 cost-of-living payments in three instalments, the government has said.
The first payment of £301 will be made in the spring, with a second of £300 in the autumn and a final £299 instalment in the spring of 2024.
Exact dates are yet to be finalised, but ministers said the money would help households with high energy bills.
A £400 discount for all energy billpayers looks set to end by April.
Charities have called on the government to do more to protect vulnerable households from soaring costs, claiming that support had not improved for those already struggling.
The government also confirmed that a £150 cost-of-living payment would automatically go to those with disabilities during the summer, and a further £300 payment would be paid to pensioners during the winter of 2023-24.
