Energy: Meters

The question

To ask the Secretary of State for Energy Security and Net Zero, what estimate he has made of the number of customers who have been overcharged for their energy use due to smart meter errors in each of the last three years.

Answered by Martin McCluskey

Accuracy levels for both smart and analogue meters must comply with the Measuring Instruments Regulations (SI 2016/1153). Consumers have the right to have their meter independently tested if they dispute its accuracy.

The Department does not hold data on the number of customers who have been overcharged due to meter errors. More broadly, customers with analogue meters are almost three times more likely to complain about billing errors than customers with smart meters.
