What recent estimate he has made of the differential in domestic energy costs between Wales and the rest of the UK.

Most recent data demonstrates that households in Wales pay a price broadly on par with the average across Great Britain for variable unit costs and standing charges for gas and electricity. Our energy price guarantee will save households hundreds of pounds this winter compared with current wholesale cost projections.

My constituent Mr Evans in the town of Kidwelly cannot benefit from a lower tariff for the electricity he uses in off-peak times because, as the engineers have explained to him, the smart meter he needs will not function owing to the almost non-existent mobile phone signal in the area, which is due to the UK Government’s failure to roll out mobile phone technology, while allowing smart meters that work only on mobile phone signals. Will the Secretary of State now have urgent talks with ministerial colleagues to put it right and end this discrimination?

I will be interested to take up that case in more detail with the hon. Lady. However, the Government, in acting radically on energy price Intervention and with our Energy Prices Bill, which seeks to break the link between electricity and gas prices, are taking the sort of action that is absolutely necessary to help households such as her constituent. Of course, I will be happy to talk further about the particular disadvantage that her constituent faces.
