In September 2019, we published our findings from a series of trials looking at how to prompt engagement in energy tariff switching. The Collective Switch (CS) trials were a subset of these trials, comprising five trials that demonstrated that a collective switch intervention was effective in increasing one-off switching among customers who had been on a default tariff for 3 years or more.
The Sustained Engagement project sought to assess whether the collective switch interventions had a lasting or sustained impact on tariff switching. We analysed the post-trial switching behaviour of participants from the first Collective Switch trial. This report outlines the insights and findings from this analysis.
