The Big Six energy suppliers’ days have been numbered for some time – now, it seems, they are officially over. Ofgem is redrawing the labels for energy suppliers in its industry data, ditching ‘Six Largest’ to make room for the challengers that have rapidly upturned the market. The administrative change marks the end of an era in which the supply of gas and electricity to British homes was in the hands of six major suppliers who controlled 98pc of the market. British Gas owner Centrica, E.ON, SSE, RWE-Npower, EDF Energy and Scottish Power were grouped by Ofgem as the ‘six largest’ and known in industry shorthand as the Big Six. But they have been upturned by challengers such as Octopus, Ovo and Bulb, who have collectively rapidly seized more than 30pc of the market over the past six years with their nimbler technology, often knockdown pricing, and making promises around green energy.
