Ofgem supplier licensing review - Which? response

We note that supplier entry has increased significantly across the energy sector recently, with over 60 suppliers currently active in the market, a doubling over the last 3 years. This should have increased choice and hence competitive pressure within the market, offering potential benefit to engaged consumers. However, we have seen limited evidence that consumers are taking advantage of this, with only moderate increases in switching rates, while improvements in customer engagement appear to have stalled.
