Up to 20,000 homes using heating oil could get a £250 payment from the Welsh government to help with the rising cost of living.
The government said £5m from a new £130m package will help “off grid” households who are dependent on either heating oil or LPG and are eligible for reduced council tax.
The package includes the £100 household energy payment, with this extended to those eligible for council tax relief “irrespective of band”.
It also includes £7m support for bus travel and £8m for councils to help those “not captured by other schemes”.
It follows the UK government unveiling a £100 “household energy payment” for council taxpayers in bands A-D in England in October.
Wales’ Deputy First Minister Sioned Williams said supporting families with the cost of living was a “key priority”.
“We understand that this is a challenging time for many households across Wales,” she said.
“In total this represents an additional investment of £130m, providing immediate relief for households this winter. While we are taking firm action wherever we can, we need the UK Government to play its part”.
Five million pounds of the package will help towards “off-grid” fuel costs with a £250 payment available to households eligible for Council Tax Reduction based on their incomes and are dependent on either heating oil or LPG.
An additional £8m will allow councils to extend the £100 payment to households “not captured” by other schemes and are facing financial hardship.
While £7m is being made available to support bus operators with their high fuel costs and protect passengers from fares increases.
The Welsh government said with winter approaching and the ongoing conflict in the Middle East, “the coming months will be a challenging time for many”.
“This package represents a significant investment in Welsh communities and reflects our determination to stand alongside households during challenging times,” it added.
