UKCSI gives unique insights into the quality of customer service supplied by organisations in the UK. 

UKCSI (UK Customer Satisfaction Index) is the national measure of customer satisfaction. It is based on a six-monthly online survey of consumers which is demographically representative of the UK population.

The July 2015 UKCSI includes 39,000 responses from over 10,000 individual customers.

The below video highlights some of the key results from the July 2015 report.

How UKCSI works

UKCSI rates the customer satisfaction of organisations in 13 sectors of the economy, covering many of the leading organisations in each sector. It also provides satisfaction ratings for each of the 13 sectors and for the UK as a whole. UKCSI was launched by the Institute of Customer Service in January 2008 and is published every six months. It provides a unique way of measuring current customer satisfaction according to UK consumers, as well as trends over time. 

UKCSI is based on customers’ actual, recent service experiences. Respondents are asked to rate individual organisations they have dealt with on a range of customer service priorities. These relate to professionalism, quality and efficiency, ease of doing business, timeliness, problem solving and complaint handling. 

How to use UKCSI 

UKCSI provides evidence about how effectively different organisations across 13 sectors are responding to changing customer needs over time. It enables organisations to benchmark against others in their sector, and the best in the UK. It also identifies the links between customer service and other measures of business performance such as brand loyalty and recommendation.

The Institute publishes a series of 13 UKCSI sector reports. These provide detailed benchmarking scores for each measure of satisfaction for individual organisations in the sector, and insights about the relative strengths and weaknesses of each sector.

Jo Causon, CEO of the Institute of Customer Service, commented:

“Many organisations are struggling to keep pace with a business environment that has undergone rapid change in recent months. Some brands are improving customer satisfaction by operating in an agile and innovative way, but overall it is clear that a new approach is required for this new environment. Businesses need to take a look at the experience they are delivering to customers and identify how it can be improved.”
