This report outlines the methodology and results of Ofgem’s five Collective Switch Trials. These trials tested whether sending disengaged energy customers a series of letters highlighting potential savings, signposting to an exclusive tariff, and offering support with switching can increase rates of customers choosing to switch to a fixed tariff. The results of these trials show that this intervention can have a substantial impact on customer’s decision to switch tariff.
