Gas and Electricity Supplier Market Share

We hear a lot about the Big 6, but just how big are the Big 6 and how is that label measured? There are two key ways to measure the size of an energy supplier and neither is related to revenue, profit, history or anything other than:
  • The number of customers or sites on supply
  • The volume of energy supplied
It is on this basis then that we can compare each of the business energy suppliers. The latest Business energy supplier market share survey, compiled on a quarterly basis by industry consultant Cornwall Energy, has revealed the stark contrast between the competitive landscapes in the gas and electricity markets However, just because a supplier is big doesn’t mean it’s bad and just because it may be small does not necessarily mean it’s a paragon of virtue. As a result this table should be used purely for interest and if you wish to know more about whether any supplier suits your needs simply visit their dedicated supplier page to find out all there is to know.

The gas and electricity markets in 2014

The Big 6 still, 20 years after the opening of competition account for nearly 80% of the business electricity market with the Big 6 taking 5 of the top six places in terms of volumetric market share. In contrast the gas market sees far less Big 6 dominance with just 20% of business gas customers being supplied by the Big 6 and British Gas Business the highest placed in 5th position. The corollary of this of course is the 'success' of independent, smaller and new entrant suppliers in the gas market withTotal Gas & PowerGazprom Energy and DONG Energy Sales taking the top 3 slots and supplying over 42% of the gas market's volume. In comparison the highest placed 'independent' suppliers in the electricity market are GDF Suez and Haven Power, both of whom manage to rank above the final Big 6 supplier Scottish Power.
