Find out how the UK’s largest and smallest energy providers ranked in the latest Citizens Advice survey.

UK's worst energy suppliers revealed

Economy Energy has been named the worst energy provider by the latest Citizens Advice survey.

The Citizens Advice star rating system scores energy firms against five criteria including:

  • Complaints ̶ how well energy suppliers handle customer complaints;
  • Ease of switching ̶ the number of switches the supplier successfully carries out within 21 days;
  • Ease of contact ̶ how highly people rate their supplier's customer service;
  • Bill clarity ̶ how easy people find it to understand their bills;
  • Switch Guarantee ̶ whether the supplier is signed up to the switch guarantee that commits them to switching a customer within 21 days.

Economy Energy only managed to rack up a star rating of 2.2 for its service between April and June this year, falling dramatically from the previous quarter's third place score of 3.85.

SSE led the way in this quarter's figures, scoring and impressive 4.5 out of 5 stars, closely followed by Ecotricity on 4.4.

First Utility made the biggest improvement, with a score of 4.1 up from 2.9 stars.

Which? energy survey

In January, npower come bottom of the annual Which? energy company satisfaction survey for the seventh year running.

The survey asked nearly 9,000 energy customers to rate suppliers on a variety of factors including customer service, value for money and accuracy of bills.

Each supplier was then given a customer score based on their overall satisfaction rating and the likelihood of being recommended to a friend.

The average customer score was 56%, but npower scored just 44%.

Extra Energy customers were the next most fed up (49%) which matches up with the Citizens Advice and Ofgem findings, followed by Scottish Power (50%) and Co-operative Energy (54%).

Apart from EDF, which scored 55%, the other 'Big Six' suppliers either matched or just beat the average customer score. SSE and British Gas hit 56% while E.ON managed 57%.

The best performer was Ovo Energy for the second year running, which achieved a customer score of 78%.

Here's how the all the suppliers stacked up:
