Ofgem has launched an investigation into sales practices by Economy Energy Trading Ltd.

The company supplies electricity and gas to domestic customers mostly on prepayment meters. Citizens Advice raised concerns with Ofgem in July 2016 relating to a high level of complaints against the company, particularly around its marketing and sales practices.

The investigation will ­examine whether Economy Energy breached licence ­conditions that require suppliers to ­communicate transparently and accurately with customers when undertaking marketing and ­telesales activities.
