On 31 March 2020, the Authority amended the Code to prohibit retailers from making contact with customers that had switched away and attempting to entice them back. The 31 March Code change prohibits this activity for a period of 180 days. This report shows trends in potential win-backs through time, based on what the trader responsible for the ICP enters into the registry. Customers are perfectly free to initiate contact with their previous retailer and may well choose to switch back. Hence, this report only provides an indicator of potential win-back behaviour. Users can investigate the impact of different win-back mechanisms and highlight how significant the activity is to each trader or parent company, relative to either switches away, or to ICPs won. For more insights, explore the report, or view a public dashboard   with a selection of report instances.

Two new win-back indicator reports treat a withdrawn switch and a switch-back the same as any ICP won by a trader. This allows win-back activity to be measured relative to other acquisition activities. The summary report compares win-back metrics for a period of time defined by the user. The figure below shows potential win-back activity on trader switches as a proportion of their ICP wins during the latest month. Users can hover over the bars to see the actual number of potential win-backs. For more insights, explore the report, or view a public dashboard   with a selection of report instances.

The report instance shows a daily summary of wholesale prices for 2020. An impact of the 25 March lockdown and reduced demand is apparent on prices at the end of Q1.
