Results from a robust trial show that sending a simple communication to energy customers coming to the end of their fixed term tariff can increase rates of tariff switching. This report contains details of the design and the results of Ofgem’s End of Fixed Term Communication Trial. This is part of a suite of trials led by Ofgem between 2016 and 2019 to provide robust evidence on what works in increasing tariff switching among energy customers. This randomised controlled trial tested whether sending an additional communication to customers on fixed term energy tariffs impacts on the proportion of customers who make a decision to switch to a new tariff. The trial took place in March 2019 with around 20,000 energy customers.
