Does app analytics provide evidence of behaviour changes in data? 25% of households logging on in last 96 hours Twice a day on average 90% of those households are looking at their budget settings More households are interested in viewing appliance info at a summary level than single When viewing appliance information, more households are interested in kWh than £ 04/12/2018 20

Measured impact of access to real time data Volume • Although the portfolio’s monthly consumption increased by 7% – 63% of households had a lower consumption of 16% on average • Insufficient data • No conclusive evidence other than app engagement at this stage • Other independent studies state customers are saving around £32 a year on their energy bills since the installation of their smart meters. 04/12/2018 21

Measured impact of access to real time data Shift • Although the portfolio’s peak: off - peak ratio remained the same – 37% of households had a lower percentage peak consumption of 2% on average • Insufficient data • No conclusive evidence • Let’s explore potential 04/12/2018 22
