More than £38 million was saved by 130,000 households switching energy supplier during one month of the Power to Switch campaign, the Department of Energy and Climate Change (DECC) reports.
Compared with the same period the previous year, the figures provided by Ofgem-accredited price comparison sites also show a 193 per cent increase in total savings.
There was an average saving of £312 for dual fuel switches – an increase of nearly 60 per cent, and an 80 per cent increase in the number of households who switched.
The DECC campaign, which went live on 19 February, encouraged people to switch and save by visiting www.BeAnEnergyShopper.com – generating more than 350,000 visits.
Wrapping up the campaign, Energy and Climate Change Secretary Ed Davey said: “Our campaign has helped put millions of pounds back in people’s pockets – and thousands have benefited.
“A huge increase in switching in a four-week period shows that people want better deals from energy providers – and our reforms to the market have driven competition and made that possible.”
Energy and Climate Change Minister Amber Rudd added: “What a terrific response to our campaign – thousands are better off and taking advantage of more competitive deals on the market. It’s not too late – even more people can still switch and save today.”
