UK Customer Satisfaction Index

The UK Customer Satisfaction Index gives a unique insight into the quality of customer service in your sector. So you can see who's leading the pack, and how you measure up.

UK Customer Satisfaction Index (UKCSI) is the national measure of customer satisfaction. It gives a unique insight into the quality of customer service in the UK as a whole and 13 sectors of the economy. It is based on a six-monthly online survey of consumers which is demographically representative of the UK population.

To create the UKCSI, The Institute of Customer Service runs an online survey of consumers twice a year. Respondents are representative of the UK adult population by region, age and gender.

It is a national measure of customer satisfaction providing insight into the state  of customer satisfaction in the UK, across 13 key sectors.  Launched in 2008, it provides a unique way of measuring the current customer satisfaction of UK customers, as well as trends over time. 

Respondents are asked to rate their experience of individual organisations they have dealt with in the previous three months, using a scale of 1 – 10, on a series of metrics covering professionalism, quality and efficiency, ease of doing business, timeliness, problem solving and complaint handling as well as attitudes towards trust and reputation. The metrics reflect the priorities customers have identified as the most important attributes of customer experience according to The Institute of Customer Service’s research. Overall scores for each sector are the mean averages of all responses for that sector. The UKCSI score for each organisation is the average of all of its customers’ satisfaction scores. These scores are multiplied by ten so that the index scores are expressed as a number out of 100. 

The January 2018 UKCSI results are based on 46,500 survey responses, 3,000 from each sector except for Insurance and Transport which includes 4,500 responses, and Utilities which includes 7,500 responses. Each response is a completed online questionnaire relating to a customer’s experience with a specific organisation. These responses are provided by over 10,000 individual customers.
