The number of complaints made by consumers against energy companies has dropped by 32% year-on-year during 2016.

Ofgem and the Energy Ombudsman said complaints fell from around five million to 3.5 million to hit a three-year low.

Complaints had stood at 6.7 million in 2014.

Some 90% of complaints against the “big six” and medium-sized power companies were solved within eight weeks.

‘Up their game’

The Energy Ombudsman ordered firms to repay £3.3m last year.

Dermot Nolan, Chief Executive at Ofgem, said: “We are seeing clear signs that some suppliers are competing harder on customer service.

“This is good, as it puts pressure on poor-performing companies to up their game or lose market share.”
