I haven't the will to pick out previous threads dealing with this so just want to flag this information
https://www.gov.uk/government/news/400-energy-bills-discount-to-support-households-this-winterAs part of this package, we are confirming today that further funding will be available to provide equivalent support of £400 for energy bills for the 1% of households who will not be reached through the EBSS. This includes those who do not have a domestic electricity meter or a direct relationship with an energy supplier, such as park home residents. An announcement with details on how and when these households across Great Britain can access this support will be made this Autumn.
So no details yet but clear indication that something is intended.
