Currently they employ about 20,000 people in the UK, and produce about a fifth of the UK's electricity.
The Which? Customer Satisfaction Score
The customer satisfaction score is based on the responses consumers gave for both overall satisfaction and likelihood to recommend the supplier to a friend. Both questions are given equal weighting, and only those giving a valid response to both questions are included in the analysis. The responses are then analysed and scaled to give a rating between 0% and 100%. The survey was undertaken in 2015. Full details of the survey can be found on the Which website.
