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 July 2018 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.

Latest results

  • Overall customer satisfaction stands at 77.9 (out of 100), down 0.2 points compared to January 2018 and 0.3 points compared to July 2017 - the first time since January 2015 that two consecutive UKCSI surveys show a decline in overall satisfaction.
  • Retail (non-food) continues to be the strongest performing of all sectors with a score of 82.1. Satisfaction in the Banks & Building Societies sector is at the highest point ever recorded, while Transport remains the lowest rated sector amongst customers.
  • The number of customers experiencing a problem with an organisation fell slightly, but the number of 'right first time' experiences fell by two percentage points. The proportion of customers’ problems that cited an organisation 'failing to keep its promises and commitments' more than doubled - from 5.3% to 12%.
  • For the first time, customers were asked about what specifically organisations should do to improve their service. Over a quarter of respondents said their top priority was for organisations to 'make it easier to contact the right person to help me.'
  • The latest results further affirm the conclusions of The Institute's breakthrough research, 'The Customer Service Dividend', which found that organisations that maintain higher customer satisfaction than their sector average have achieved stronger turnover growth, profit and employee productivity than those whose customer satisfaction is below the sector average.
