Sam Laidlaw, Centrica chief executive, pointed towards the group's tax contribution and investment in future energy sources:
We have taken the lead during 2012 in helping more households save energy and supporting the people who need the most help.
It’s important that Centrica makes a fair and reasonable return so that we can continue to make our contribution to society and to invest.
Last year we incurred a tax charge of over £1 billion and invested over £2 billion to secure new sources of energy for the UK, well in excess of our profits.
