Chart of the week | Take on me: market share impacts of domestic supplier trade sales

This week, we look at the market share impacts of recent mergers and acquisitions among domestic energy suppliers. Over the last year, the headline changes saw incumbent suppliers, npower and SSE, exit the domestic supply market with customers going to E.ON UK and Ovo Energy, respectively. The consolidation has resulted in Ovo Energy achieving 14.5% market share by energy accounts and becoming the second largest supplier. While we reported E.ON UK and npower market shares separately in our 31 July Domestic Market Share Survey, the combined market share at this point would reach 16.6%.
