Nearly half a million customers switched electricity suppliers last month.
That’s a 4% increase from March, bringing the total number of switches to just under 1.8 million so far this year.
Nearly a quarter (23%) of customers moved from the Big Six companies to small and medium sized suppliers.
Last year, a record 5.5 million customers switched to different energy companies.
Lawrence Slade, Chief Executive of Energy UK said: “Almost two million customers have already switched suppliers this year. Calling your supplier – or having a look online to see if you’re on the best deal – is one of the quickest ways going to potentially save yourself hundreds of pounds a year.”
The Energy Switch Guarantee, a voluntary industry initiative to provide consumer confidence in switching, found nine in 10 customers are happy with the process.
