British Gas

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.

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

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.

EDF Energy has followed British Gas in going on a charm offensive to help regain the public's trust.

Ovo Energy has bucked the trend of falling gas and electricity prices by announcing up to 90,000 of its customers face a hike in their bills. But will the big six follow, which would hit millions of households?

British Gas will add a comparison table of its tariffs to its bills from April, so customers know whether they can save money by switching to another of its products.

Scottish and Southern Energy (SSE) is drastically simplifying its range of tariffs after regulator Ofgem called for a shake-up of the industry.

Scottish Power has become the last of the big six energy companies to announce reductions in its tariffs.

Eon today became the latest energy supplier to cut prices when it announced a 6% fall in electricity bills, benefiting 3.7 million customers.
