There is a strong link between satisfaction and price, with customers spending more than £360 annually, being significantly less satisfied with services. Sixteen percent of dissatisfied or critical customers were likely to change suppliers, with only 2 percent of delighted customers indicating that they would change. The number of respondents who purchase electricity from a dual fuel company has increased to 39 percent, with claimed average savings of more than 10 percent per household. The customer satisfaction study was conducted by J.D. Power & Associates of California, and was based on 5,000 interviews with domestic customers throughout Britain between June and August of this year. The interviewees were a representative sample of the 25 million domestic customers who receive electricity supplies from one of nine ranked suppliers.
