Energy supplier EDF has recorded a £903 million UK profits haul in the first half of the year, as Britons were charged more to turn up the heating.
The French-owned supplier said underlying earnings rose 2.8 percent, helped by greater gas demand from households during the coldest spring in 50 years and by selling power at higher prices on the wholesale markets.
The UK's biggest electricity generator, which supplies gas and electricity to about 3.7 million homes in the UK, hiked bills by 10.8 percent on average late last year. However, it insisted its UK retail arm continues to lose money.
Greenpeace say a dozen of its activists have entered an EDF nuclear plant in Tricastin, France, Reuters have reported.
