Here's a prediction: the Brent price fixing scandal will turn out to be larger than Libor. Energy prices ripple throughout the real economy and there will be not thousands but millions of angry punters ready to exercise a grievance if any of these allegations turn out to be true.

Richard Lloyd

Executive Director, Which?

With escalating energy prices remaining a top financial problem for households we hoped the government and Ofgem would sort this mess out by forcing all energy companies to present their prices in a clear, simple way and to make it much easier to switch.

Whistleblower at the centre of the UK gas price-fixing story

For a company so egregiously engaged in deception on a mammoth scale, SSE have got off almost scot-free in financial terms, and they and their peers know it. Ofgem levied a penalty equivalent to just 0.5% of SSE's annual revenues, demonstrating again quite how toothless and ineffectual the regulator remains.

Chief executive of Barnardo's

Barnardo's believes that the scandal of child poverty in this country will only be tackled when action is taken to improve both the income and the access to services that the poorest families have. We know that money matters to the poorest families - especially when rising living costs, stagnating wages, a weak labour market and spending cuts are placing more pressure on them than ever before. Many families in poverty in the UK live on just £12 per person per day after housing costs. That £12 has to stretch to cover everything: food, electricity, water, gas, bus fares.

Managing Director of Ovo Energy

In February The Institute for Public Policy Research (IPPR) think tank released analysis which found that as many as 5million people are being unfairl...

Maria McCaffery

Chief Executive of RenewableUK

Ofgem's figures show that the current cost to UK households of developing all forms of renewable energy, including wind, is less than £20 a year. For less than 40p a week, we can develop a thriving UK-based renewable sector, including wave and tidal energy, which will provide secure, cost-effective and clean energy for generations to come.

This week we are running Big Energy Week - a campaign to help people save money on their energy bills, get advice on any fuel debts and make sure people are getting all of the help available.

Justin Forsyth

Chief Executive, Save the Children

Getting through 2012 is no doubt a worrying prospect for many in the squeezed middle, but for families with the least, just making sure their kids are warm this winter is one of their biggest concerns. We cannot, as a society, allow this to continue.

Mark Daeche

Co-Founder First Utility

It seems that the energy headlines are here to stay. Several weeks have passed now with little change in sentiment; there is a growing anti 'Big Six' feeling and people are demanding change.

Andy Atkins

Executive director, Friends of the Earth

Soaring energy bills. Millions unable to properly heat their homes. A gaggle of profit-hungry energy giants ripping us off and making billions in profits. A Government unwilling to act to curb their power. It sounds like the plot of a science fiction movie.

Luciana Berger

Labour MP for Liverpool Wavertree and Shadow Minister for Climate Change

Instead of standing back minsters should be taking urgent action to curb soaring prices. Labour's approach would mean a real change - more competition, fairer bills, transparent pricing and extra support for those who need it.

Mike Dixon

Assistant Chief Executive, Citizens Advice

It may not be the barbecue summer we hoped for but here in the Citizens Advice office, the windows are open to get a breeze going and the central heating is still firmly switched off.

Darren Braham

Founding Director, First Utility

The summer holiday season is well underway and thoughts of central heating and the winter should be furthest from most minds. However over the past few days UK consumers ' attention has been turned to energy bills as the fourth of the 'Big Six' largest energy companies in the UK have announced their intention to increase their energy prices.
