UK Customer Satisfaction Index

The UK Customer Satisfaction Index (UKCSI) 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.

The 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 2020 UKCSI results are based on 45,000 survey responses, 3,000 from each sector except for Transport and Utilities which includes 6,000 responses each. 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.

Sector reports

The sector reports examine the attributes of the customer experience most important to customers in the sector and how this compares to customer satisfaction for these measures. They contain benchmarking of sector and national results on key complaints measures such as the type of complaints, channel used when making a complaint, the reactions encountered by customers when making a complaint and the time taken to resolve complaints.

There are 13 industry sector reports available. Each allow you to:

benchmark customer satisfaction performance against other organisations in the sector on over 30 customer experience metrics
- analyse overall customer satisfaction, NPS, customer effort, trust, reputation
- link customer satisfaction to future buying behaviours, including consumers likelihood to repurchase, remain a customer and recommend
- identify what differentiates the highest and lowest performing organisations in each sector
- understand the latest evidence about drivers of complaints and satisfaction with complaint handling
- compare findings with your own customer surveys, business benchmarking surveys or voice of the customer analysis

Customers' Priorities
The questions in the UKCSI are based on customers’ priorities – the attributes of customer experience with organisations that are rated as most important by customers. The Institute conducted recent research into customers’ priorities to ensure that the UKCSI remains a relevant and essential benchmark. The output of this research is new insight into both customers’ stated priorities, as well as “softer” factors which may not necessarily have a high stated importance, but nevertheless show a strong relationship with customer satisfaction.

As well as reporting an overall index score based on customers’ responses across the full range of measures, this report includes index scores for five distinct dimensions of the customer experience: Experience, Complaints Handling, Customer Ethos, Emotional Connection and Ethics.
