The Scheme is intended to facilitate the £400 payment of support for domestic energy consumers in Great Britain that would otherwise not receive that support through the Energy Bills Support Scheme due to the absence of a domestic electricity supply. Once domestic energy consumers have applied to receive support and their application has gone through internal verification, eligible applicants' details will be shared with local authorities (for England, Scotland and Wales).
