British Gas: Where your money goes - in under a minute

British Gas owner Centrica has reported a rise of 9% in half-year profits, after an unusually cold winter boosted gas consumption.

Centrica's adjusted operating profit rose 9% to £1.58bn for the period ended 30 June 2013, up from £1.45bn for the same period in 2012.

Meanwhile the residential arm of British Gas saw profits rise 3% to £356m, up from £345m a year earlier, following a 6% increase in its energy prices last November.
