Concern for Welsh consumers
Consumer Focus Wales energy policy advocate Ceri Williams said: ‘It will be of concern to Welsh consumers that they are paying more for their electricity than consumers elsewhere.
‘Because of these higher costs, it’s important for consumers to make sure they are getting the best deal from their energy supplier.’
Why bills are higher in Wales
The report found that the main reason for the difference is the higher cost of electricity distribution in areas with a low population.
It costs about £20 a year more to distribute electricity in northern Wales than the rest of Britain, and £25 a year more in south Wales.
