Almost a million households can now start applying for government help towards their energy bills, which was promised to help them through the winter.
Most households have been getting £400 in energy support, paid in monthly instalments since October.
But those in park homes, care homes and living off-grid have not yet seen a penny. Some say they feel "forgotten".
The government says it knows this is a difficult time for families.
It says it is working to serve these additional households.
But it could still take weeks for these households to receive the payment. lucabet
