Customer Churn in European Energy Retail: What the Data Shows

Annual churn has reached 24% in some European markets, and replacing a single lost customer costs an estimated €150 to €200. That makes retention a direct margin concern. The question is whether retailers can identify risk early enough to act before a customer leaves. Bidgely analysed data from 2020 through 2025 across three European energy retailers serving approximately 1.15 million enrolled customers at year-end 2025. Across all three, sustained engagement with Bidgely's platform correlated with lower annual churn. One retailer reduced annual churn by 44% over two years. A second reduced churn by 20% while nearly doubling enrolment. A third reduced annual attrition by 11% year over year while maintaining below-average churn throughout the analysis. The behavioural data shows what separated the two groups before their contracts ended. At the first retailer, retained customers averaged 46% more portal sessions per user than customers who churned. At the third, churned customers rejected personalised energy tips at a 52% higher rate. Across all three, retained customers generally engaged more often and rated digital interactions more favourably. Engagement quality can serve as an earlier indicator of churn risk, and an earlier window to intervene.
