I am an Economy 7 customer, what does this mean for me?

Economy 7 customers will see an increase of 4% to the price they pay. This means customers will pay around £34* more per year. 

*On average, customers will pay £38 more per year. This is calculated using the Power NI unit price increase of 4%, with a weighted average of the Power NI E7 standard unit rate and an average household usage of 3,200 units (kWH) per year.
