E (Gas and Electricity) has been named the best energy supplier in the UK by consumer group Which?, with 86% of its customers saying they would recommend the provider. It achieved an overall score of 79%, earning four stars for customer service, ease of contact, and clarity of statements.
At the bottom of the rankings, Scottish Power received the lowest overall score of 56%, performing poorly in complaint handling. EDF scored 58% due to limited phone line and email monitoring hours, while British Gas scored 59%, struggling with complaint resolution and switching despite offering good support.
Octopus Energy came second with 74%, followed by 100Green and Sainsbury’s Energy, both scoring 72%. Co-op Energy and Outfox Energy also scored 71% but failed to achieve three stars in every survey category.
Which? surveyed nearly 12,000 energy customers in September and October, also assessing 17 firms' behind-the-scenes practices. Which? Energy editor Emily Seymour said: “Our research shows that while four suppliers are outshining the competition, some big firms – including Scottish Power, EDF and British Gas – are letting their customers down.”
In response, a Centrica spokesperson (owner of British Gas) noted complaints have fallen over 20% each year for two years, while an EDF spokeswoman highlighted its Trustpilot rating of 4.8. A Scottish Power spokeswoman pointed to the Citizens Advice scorecard as a more robust measure of performance.
