Amazon is still number one in the UK Customer Satisfaction Index (UKCSI), published by The Institute of Customer Service.

With a customer satisfaction score of 86.7 points (out of 100) this is the sixth consecutive time consumers have rated Amazon number one.

Eight non-food retailers make up this year’s top 20, and the retail sector performed better than any other boasting an average score of 82.2, against a backdrop of challenges that continue apace for High Street brands.

The food retail sector performed best after non-food retail with an average score of 81.2. Iceland took the top spot for the first time, whilst also claiming the title of most improved supermarket, having climbed 26 places in the rankings in just six months.

Four financial institutions made the top 10 organisations, with Yorkshire Bank scoring highest, followed by First Direct and Nationwide. The banking sector overall performed better than ever before, reaching a score of 80.4 and exceeding the UK all sector average score of 77.9.

The Institute warns that “survival of the fittest will be driven by how well customers are served”. After a steady increase in the first five years of the last decade, the latest UKCSI shows levels of UK customer satisfaction across all brands peaked in 2012/13 and have largely plateaued since.

The UKCSI is the national measure of UK customer satisfaction. It rates customer satisfaction at a national, sector and organisational level across 13 sectors – incorporating the views of 10,000 consumers. More than 30 different customer measures are surveyed – such as staff professionalism, the quality and efficiency of the service, trust and transparency scores, the actual customer experience and complaint handling – are factored into the results. It is published twice a year, in January and July.

Jo Causon, CEO of The Institute for Customer Service said: “The stagnation in customer service levels should be of concern for the UK economy. This comes at a time when, just nine months from Brexit, we need more than ever before to show that Britain is a great place to do business with and in.

“Alongside tangible financial measures, trust, reputation and recommendation are crucial benefits of a deliberate and consistent focus on achieving high levels of customer satisfaction. The UKCSI shows that customers who give the highest ratings for customer satisfaction – express strong levels of loyalty, which brands will need in difficult and unpredictable market conditions.”

This UKCSI’s top organisations are rated favourably for measures of customer effort, trust, ease of contact, employee helpfulness and competence, speed of response, getting things right first time and complaint handling.
