The Big Six are the United Kingdom's largest energy suppliers, supplying gas and electricity. The Big Six are British Gas, EDF Energy, E.ON, Npower, Scottish Power, and SSE.

As of Q3 2018, the Big Six held a combined market share of 75% for electricity supply and 73% for gas supply in Great Britain. They previously held a combined market share across both markets of 100% in 2004.[1][2]

Ovo Energy acquired SSE's retail customers, effective January 2020, but will continue to use the SSE brand for the time being.[3][4]

Possible consolidation to Big Five[edit]

In 2017, SSE and Npower announced a merger of their retail businesses,[7] but this was scrapped in 2018.[8]

Just after the failed SSE-Npower merger in late 2018, it was reported that a consolidation to the Big Five would still occur, as Npower would be acquired by default by E.ON due to the already-planned asset swap by the respective German parents, innogy and E.ON.[9]

Ofgem investigation[edit]

In June 2014, energy watchdog Ofgem referred the energy industry to the Competition and Markets Authority (CMA). The 18-month investigation is to conclude whether the big six have been profiteering and should be broken up.[10]

Alternatives to the Big Six[edit]

In December 2014, Utility Warehouse, part of FTSE 250-listed company Telecom Plus became the UK's biggest independent energy supplier through a £218m deal to buy 770,000 existing customers from npower.[11] In September 2014, First Utility (since rebranded as Shell Energy) announced it was the first independent utility supplier to reach the milestone of 1m customer accounts for gas and electricity – the equivalent of 550,000 customers, which made it the seventh-largest energy supplier in the UK and the country's biggest independent energy provider.[12] In June 2015, a Cornwall Report stated Opus Energy had broken the dominance of the 'Big Six' energy suppliers in the business market.[13]

The Competition and Markets Authority published an investigation into the energy supply market in June 2016, following a referral by Ofgem in June 2014.[14] The report identified 34 suppliers of both electricity and gas to households, and described the three largest suppliers outside the Big Six as "mid-tier suppliers"; these were First Utility, Ovo Energy and Utility Warehouse. Other significant suppliers (each with more than around 1% market share) were Co-operative Energy, Extra Energy and Utilita Energy (specialising in pre-pay customers).[15] The combined market share of suppliers outside the Big Six had increased from less than 1% in 2011 to around 13% in the first quarter of 2016.[16]

Since 2009, other entrants into the market include a number of new energy companies including Bulb Energy, Good Energy, Ecotricity, and Octopus Energy; and, in 2015, the first local authority-owned energy company since 1948: Robin Hood Energy. Many of these newer entrants are seeing significant growth in customer numbers, in part due to their greater commitment to renewable energy and, in the case of Co-op Energy, community renewable energy projects.[17]

Defunct competitor companies[edit]

By January 2019, ten[18] small energy suppliers had ceased trading or been taken over by others. This number increased to sixteen by the end of that year.[19]
