What Are the Big Six Energy Companies?
The Big Six energy companies are the six largest energy suppliers in the UK but, what you may not know, is that the Big Six has actually changed in recent years. Such changes were primarily brought on by the energy crisis the UK has faced in the last few years. In 2019, the big six were:
- British Gas
- EDF Energy
- E.ON
- ScottishPower
- SSE
- RWE npower
Following the crisis, and the collapse of many independent providers, the 'Big Six' currently consists of seven companies, they are:
- British Gas
- EDF Energy
- E.ON Next
- Octopus Energy
- OVO Energy
- ScottishPower
- Shell Energy
Shell Energy will soon be leaving the list, following its decision to sell its UK domestic energy business. After its departure, there will be a recognisable 'Big Six' again. Shell Energy will continue to supply businesses like yours, they just won't be as big a name as they are now.
The Big Six energy companies play a vital role in the UK energy market and are responsible for generating and supplying energy to 90% of UK homes, along with millions of businesses. They also invest in new energy infrastructure and technologies, like green alternatives to fossil fuels.
How do they Compare to Each Other?
The Big Six energy companies vary in terms of size and market share. They all, however, offer a range of gas and electricity tariffs to their customers, as well as other services such as boiler covers and smart meters.
British Gas is the largest energy supplier in the UK, while EDF Energy is the second largest, and is a major generator of low-carbon electricity, including nuclear power.
Octopus Energy, the fourth largest supplier in the UK, is known for its competitive prices and its focus on renewable energy. ScottishPower is the sixth largest energy supplier in the UK and is a major generator of hydropower and wind power.
