Millions of energy customers are set for lower fuel bills after the latest price cuts come into force today.
Scottish Power, which has 5.2 million customers, has cut gas prices by up to 16.5 while electricity prices have fallen by up to 5.5 per cent.
The company, which was the last of the big six energy providers to cut prices, said the move would bring the average dual fuel bill for direct debit customers down by £75 to £836 a year.
EDF has also cut gas prices by 10.2 per cent for those on standard tariffs from today although its electricity prices will remain the same.
It defended its move not to slash electricity prices by claiming its electricity bills had the smallest price rises compared with competitors last year.
This latest round of price cuts was sparked by British Gas’ decision to slash bills in February on the back of cheaper wholesale gas prices.
Last week Which? revealed that some energy customers are paying more than 30 per cent more for their power than people in other parts of the country – even though they’re with the same supplier.
That’s because price reductions often work out unequally across the UK’s 14 energy regions.
Energy companies that were the dominant supplier in a region before deregulation – or those that already have a large market share – usually charge more for their standard tariffs than companies trying to increase their customer base in that area.
Effectively this means that if you’ve never switched supplier you’re getting a poorer deal than those who have.
