Major energy suppliers ranked best to worst as firms urged to ‘up their game’

MILLIONS of customers at some of Britain's biggest energy firms are receiving treatment that falls below expectations, according to research. Thousands of households were asked how satisfied they are with their supplier by consumer group Which?. At the same time, energy firms were assessed on their behind-the-scenes practices and policies to give an overall score.

It comes as energy prices have stabilised with more fixed deals returning to the energy market, which sees customers tied into staying with a provider for a set amount of time. With the energy price cap predicted to increase in April, switching to a fixed deal could well be the best way for consumers to cut costs over the next six months.

However, many deals are at a similar price point so customer service should be a major factor when deciding which supplier to switch to. The top rated firms were Octopus Energy, Utility Warehouse and 100Green. On the other hand, some of the biggest and best-known firms including British Gas, Scottish Power and Ovo Energy were ranked worst with overall scores below 60%.
British Gas is one of the UK’s biggest suppliers but is failing customers, according to Which?’s research. The firm's customer service was below average; in Which?’s assessment, the supplier performed poorly for the volume of customer complaints it received in the first half of 2024 and for how efficiently it resolved issues.
