Which? verdict on So Energy
So Energy is included in our survey for the second year, since it was founded in 2015, and on both occasions it has done well.
Customers gave good feedback overall on all of the aspects of its service we asked about, but were particularly enthusiastic about its value for money, bills and online customer service (all of which received a top five stars out of five rating).
So Energy prices
The highest proportion of customers of any supplier rated So Energy good or excellent value for money – that's 93% of customers.
Such positive feedback is likely to be bolstered by So Energy’s ‘low price policy’ which claims its single fixed tariff will always be in the cheapest 10% of energy deals available for the average user. So Energy says it looks at the average annual cost of gas and electricity for a ‘medium’ user across the UK to establish this.
The ‘low price policy’ applies to both single rate and Economy 7 meters. It only applies to its fixed deal - so once your tariff expires, so will the price promise.
So Energy was also highly praised by customers for its bills. Of all the firms included in our survey, So Energy customers were most likely to rate bill accuracy good or excellent.
So Energy customer service
It also achieved a full five stars for its customer service online; one of 11 firms to do so. Its phone customer service was rated slightly less well, receiving four out of five stars.
Customers can also speak to So Energy quickly, according to our latest energy companies call waiting times investigation. So Energy was among six energy firms to answer calls in under a minute on average.
It responded to customer emails in under a day on average during our investigation.
So Energy gives its customers the chance to vote for where they want their energy to come from using an online polling system.
Although we didn’t receive enough responses to give So Energy a rating for complaints handling, it gets a very low level of customer complaints, according to industry data.
So Energy received four stars out of five for helping customers understand and reduce their energy use.
So Energy currently doesn’t cater for prepayment meters, although will take customers on Economy 7 meters.
