Edinburgh West MP Christine Jardine has tabled an amendment to the Energy Bill to address geographical differences in electricity standing charges.
Consumers in Southern Scotland currently pay 60% more than those in London with only one other region in the UK (North Wales and Mersey) paying a higher standing charge.
Gas standing charges are the same across the UK.
Christine pointed out that in a cost of living crisis, standing charges disproportionately affect those on lower incomes and exacerbate an already difficult situation for many.
Christine said: “This is all about trying to take the strain off of people including those in my constituency who are being asked to pay more in standing charges because of where they live in the country.
“Action on this could make a difference to many of my constituents who have had months of coping with high energy bills and a rocketing cost of living while knowing they are paying more in standing charges than many others.
“It seems unfair that anyone, anywhere in the country should have to pay considerably more. That is why I have tabled this amendment in search of a resolution.
“I would urge MPs from all parties to back my amendment, put an end to these regional discrepancies, and allow charges to fall.”
