Neil Clitheroe, CEO, Retail and Generation at ScottishPower, said:
"The CMA backs competition and dispels the myths that wholesale energy markets or vertically integrated companies are not working in the interests of consumers.
"But more needs to be done to improve competition so that the retail market works better for consumers, including addressing the CMA’s concerns about potential higher prices due to weak consumer engagement.
"With over half of our cash and direct debit customers benefitting from cut-price deals within the last two years, ScottishPower is pleased that the CMA recommends finding even better ways to unstick more customers. What is needed now is space for competition to breathe properly to allow consumers more choice not less.
"We look forward to working with the CMA and the government to simplify regulation for the benefit of all customers.”
