The second Cost of Living Payment for 2023 was scheduled to be paid automatically to eligible claimants between 31 October and 19 November 2023. This payment was £300 and was given to those on specific benefits such as Universal Credit, Income-based Jobseeker's Allowance, Employment and Support Allowance, Income Support, Working Tax Credit, Child Tax Credit, and Pension Credit, with eligibility based on entitlement during the period from 18 August 2023 to 17 September 2023.
There is no indication of a new or second Cost of Living Payment for 2025 in the information available; the last known payments were made in early 2024, and the scheme ended after that. New payments beyond those are not currently announced by the government.
If this answer relates specifically to the current period (2025), there is no scheduled second Cost of Living Payment at this time.
