moneysupermarket.com: Scottish Power price rises

Commenting on price rises from Scottish Power (14 per cent for electricity, 15 per cent on gas, and 14.8 per cent on dual fuel) Scott Byrom, utilities manager at price comparison site moneysupermarket.com, said: "This move from Scottish Power will have the greatest negative impact on customers in Southern Scotland, North Wales and parts of North West England.

"Scottish Power has 1.86 million customers there – the bulk of whom are on its Standard tariff. The argument to change to an online Monthly Direct Debit tariff now is stronger than ever.

"Even before this move, Scottish Power's Standard dual fuel tariff was averaging £216 more than British Gas Click Energy 4 – now the difference is over £350."
