Who are the Big Six energy suppliers?
Britain’s largest energy suppliers are known collectively as the ‘Big Six’, and between them they supply gas and electricity to over 50 million homes and businesses across the UK.
The Big Six are also the UK’s longest running private energy suppliers, having all formed during the 1990s following the passing of the 1989 Electricity Act, which paved the way for the privatisation of the energy sector.
Energy supply isn’t all about the Big Six though – a growing number of smaller independent suppliers have been entering the UK market since 1997, with the aim of providing real competition for the major providers and creating a fairer market for consumers in the process.
