British Gas: Profit and price rises 'not connected'

British Gas has reported a rise in profits for 2012 after colder weather led to people using more gas.

Profits from its residential energy supply arm rose 11% from a year earlier to £606m. It said gas consumption had risen by 12%.

But there has been some criticism that the company increased its prices in November when profits were rising.

The company's managing director of energy, Ian Peters, says the price increase is not linked to the profit increase.
