Electricity

EDF, Npower and Scottish Power have refused to state whether they are likely to raise gas and electricity prices this year, following today's decision by Eon to freeze bills for the rest of 2012.

Energy giant Eon has today promised to freeze gas and electricity prices for all of its domestic customers between now and the end of the year.

Co-operative Energy will supply gas and electricity for the first 30,000 households to sign up to 'The Big Switch', the nationwide collective campaign from consumer group Which?.

Households are being warned of more energy price hikes after British Gas owner Centrica said its costs were continuing to rise.

Consumers have been warned the cost of new energy deals is creeping up, after Scottish Power became the second provider in a month to replace its online tariff with a more expensive offer.

Collective switching by consumers between utility firms could put an end to poor deals and unresponsiveness from suppliers, according to a report.

The gap between the 'true cost' of energy and what consumers actually pay will swell to nearly £2 billion in 2020 unless there is tougher regulation, a think tank warned today.

The big six energy companies – EDF, Eon, British Gas, Scottish and Southern Energy, Scottish Power and Npower – have agreed to write to customers every year to tell them the firm's best tariffs for them and how to get it, the Government will announce today.

Energy regulator Ofgem has opened an investigation into whether industry giant Eon is mis-selling to consumers.

More than half of EDF's customers are unhappy with the service they get when they complain to the energy giant, according to a survey by the industry regulator.
