Millions of EDF Energy customers continue to benefit from Winter Price Freeze Guarantee until the start of March

Today's announcement sees EDF Energy become the last major supplier to announce a price change, increasing its standard residential gas unit prices for the first time since 2009.
The change amounts to an increase of £1.31 per week on a nationally averaged typical Dual Fuel direct debit bill.
EDF Energy stood apart from the other major suppliers by committing to a price freeze during a particularly cold winter, when gas consumption is at its highest. As a consequence, EDF Energy customers have benefited from some of the lowest prices in the market when it matters most. A typical customer will have consumed just over half their annual gas consumption during this period and this year winter gas consumption was even higher than usual during the coldest December in 100 years (please see graph below). EDF Energy has also been among the cheapest two suppliers for standard dual fuel customers paying by cash/cheque for 90 out of the past 100 weeks.
Effective purchasing of wholesale gas many months in advance enabled EDF Energy to protect its customers from a price rise during each of the last two winters. However, increasing wholesale prices and non-energy costs, such as higher network charges and new environmental obligations, have forced the company to raise prices from 2 March.
