"We have found that the 6 largest suppliers have learned to take many of their existing domestic customers — some 70% of whom are on 'default' standard variable tariffs — for granted, not just over prices, but with their service and quality. Yet in those parts of the retail markets where competition is working, customers are benefiting to the tune of hundreds of pounds a year by switching. We're proposing a wide range of bold, innovative measures to enable competition to grow further across the market so that millions more households will benefit."
