A statement from Spark
Dec 02, 2014 by Spark Energy
In common with other energy suppliers, Spark Energy has identified that some Landis and Gyr gas prepayment meters have been calculating customers’ energy use inaccurately. The issue only affects customers who use a prepayment meter for their gas.
The meters were inherited by Spark from other energy suppliers. The gas prepayment meters have not been updating the correct calorific value into the meter set and as a result, have been over calculating energy consumption since 2007. A repair programme is currently being agreed with Ofgem which will see affected meters updated to ensure that the right calorific value is programmed into customers’ meter sets.
Spark is working closely with Ofgem and the rest of the energy supply industry to ensure that the issue is rectified as soon as possible.
We will be directly contacting and proactively refunding, each and every one of our customers as a matter of priority - before Christmas. As well as refunding customers in full for the overcharging we will go over and above this by including projected usage to March 2015 so that customers are not left out of pocket.
