Failing to make the ban on acquisition-only tariffs (BAT) permanent will be a “kick in the teeth” for energy customers, So Energy’s chief executive has said. Alongside Ofgem’s price cap announcement, the energy regulator revealed that it will extend the ban for another 12 months, but added it intends to open a consultation to consider shortening this extension to just six months. The news has been met with frustration by Simon Oscroft, So Energy interim chief executive and co-founder, while Octopus Energy has also raised concerns about ‘tease and squeeze’ tactics.
