The worst energy companies have been named and shamed in an annual survey carried out by consumer champion Which?
Only Octopus Energy won a five star rating, and a 78% overall rating, with nine out of 10 customers saying they would recommend the supplier. At the other end of the scale, Scottish Power scored only 51% based on customer feedback and an assessment by the consumer champion.
The results were revealed as campaigners call on firms to do more to protect struggling customers, as Citizens Advice revealed three million people on prepayment meters were cut off last year because they couldn't afford to top up.
