These figures show how the profits of energy companies are set to rise:
- The average margin for a typical, standard tariff dual fuel customer is approximately £50 (£5 higher than Ofgem's previous estimate)
- But it's expected that profit margin will rise to around £70 over the next three months
- It's because bills for some customers are going up
- Bills may also need to rise by 14% to 25% to pay for investment to increase Britain's energy systems by developing more low carbon power stations
