“The Big Six have repeatedly failed to deliver a decent standard of service” – Which? response to Cornwall Energy data showing 660,000 customers have switched away from Big Six suppliers in the last year.

Which? executive director, Richard Lloyd said:

“The Big Six have repeatedly failed to deliver a decent standard of service so it’s no wonder customers are starting to leave them in droves. Despite this the CMA has found there is a lack of competition which is leading to people paying much more than they should.

“We now ​need the competition inquiry to bring forward radical changes to boost competition, introduce fairer prices and encourage more households to switch to better deals.
