Transforming customer retention and reducing bad debt risk

Spark

Challenge

Spark Energy occupied a unique position in the UK energy market, onboarding over 10,000 home movers each month through letting agent partners. Despite this advantage, engaging rental customers remained difficult. Direct debit penetration was low, bad debt risk was increasing, and call centres were overwhelmed with repetitive, low-value enquiries. Customer wait times stretched to 30 minutes, resulting in poor experience and high operational costs
