Summer switching reached a new high, with more than 360,000 customers moving to a different supplier in June.
More than two million customers have switched their energy suppliers in the first half of this year, according to Energy UK.
That’s 1.5 million more than the first six months of 2014, it adds.
New data also reveals more than 120,000 consumers switched to small and mid-tier suppliers last month – 33% of all switches.
Lawrence Slade, Chief Executive of Energy UK, said: “It is great to see more and more customers shopping around over the summer months before winter hits.
“Since June 2014 the cheapest tariffs have fallen by over £200. There are now around 50 deals under £900 on offer. The new Energy Switch Guarantee – launched by the Industry last month – has made it even easier for customers to switch.”
