Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty's Government what assessment they have made of the accuracy of gas meters and smart meters.

Gas meters used for billing must be of an approved design and be accurate. Accuracy limits for smart and ‘traditional’, non-smart meters are identical and set out in legislation.

The Office for Product Safety and Standards manages an annual in-service testing regime to test the accuracy of gas meter types. Testing is undertaken on the basis of sampling and to date all gas meter types sampled have passed.

In the event of a dispute over the accuracy of a meter, the law gives all consumers the right to have their gas meter independently checked and tested. The vast majority of meters tested as a result of consumer dispute are found to be accurate.
