But our ambition is clear – collectively, we need to build a transformed energy sector that provides secure and clean energy to consumers – at a cost that consumers recognise as fair. Ofgem will continue to monitor energy markets to ensure that we act quickly to address problems. Where the market is not working well, we are taking action to protect consumers, both by reducing the harm that results, and by tackling the root causes. But this report makes clear that solving these issues needs continued action on our part, and on the part of companies and government. We would like to thank all of those organisations and individuals who helped us to produce this report, including the Department for Business, Energy and Industrial Strategy, the Committee on Climate Change, Which? and Citizens Advice. The report draws on the work of many people across Ofgem. Following the Competition and Markets Authority’s recommendations, it was led by Ofgem’s Office of the Chief Economist, separately from Ofgem policy teams. We are happy to hear from you.

We use gas and electricity to heat our businesses buy energy homes and workplaces, power the phones we hold in our hands, the appliances we cannot live or work without Competition continues to benefit consumers and, increasingly, our cars. British households spend who are able and willing to shop around, around £30 billion on gas and electricity each year, an meaning they can usually get a good deal. As of average of around £1,123. Businesses, charities and June 2017, there were 60 suppliers offering electricity public bodies spend an extra £20 billion each year. and or gas, 16 more than a year earlier. Since 2012, new suppliers have intensified competition, shrinking Energy markets are rapidly transforming to meet our the six largest energy suppliers’ share of the market need for clean, secure and affordable energy and to from nearly all consumers to just over 80% of them. accommodate changes in the way we consume energy.

The transformation is being helped by major investment in generation, networks and But competition isn’t working well for consumers energy efficiency. But the benefits of these investments who are less active. More than half of consumers will only flow to consumers if energy markets work well.
