An independent review looking at ways to reduce energy costs has been launched by the government.
The study will examine how the UK can keep household bills down while also meeting its climate change targets.
Oxford University professor Dieter Helm, who is carrying out the work, said he would “sort out the facts from the myths about the cost of energy”.
The launch comes just days after British Gas raised electricity prices by 12.5% for 3m customers.
The study, which is expected to be published in October, will look at the key factors affecting bills – including energy and carbon pricing, efficiency measures and regulation.
It will consider how costs can be reduced at all stages of the energy supply chain, as well as the impact of new technology on the sector.
