Energy Providers in the United Kingdom

What's the situation?

Since the energy markets were privatised in 1990 by the Thatcher government, the UK's gas and electricity markets have been open to competition. This has led to the formation of an 'oligopolic', restricted marketplace fronted by the 'Big Six' Energy companies.


The Big Six

The 'Big Six' refers to the six energy companies that currently hold around 85% of the market share in the UK. These include: British Gas, EDF Energy, Npower, E·ON, SSE, and Scottish Power. Although these companies have enjoyed a largely uncontested reign over the last 20 years or so, there now exists a desire to overthrow the habitual, more-expensive, 'Big Six' companies. This has been done by the market inclusion of a select few independent energy companies.


Independent Companies

For the first time since the solidification of the 'Big Six' (which them themselves were formed from already established gas and electricity boards), there has emerged a handful of new competitors in the energy market that are in close competition with the 'Big Six'. Four of these independent energy companies now hold 8% of the market share. These four companies are First Utility, Utility Warehouse, Ovo Energy and Co-operative Energy.
