The UK Customer Satisfaction Index (UKCSI) is an independent, objective benchmark of customer satisfaction on a consistent set of measures on over 281 organisations and organisation types in 13 sectors.

A barometer of customer satisfaction in the UK since 2008

The UKCSI (UK Customer Satisfaction Index) provides insight into the state of customer satisfaction in the UK for 13 key sectors. The UKCSI is published twice a year, in January and July. Each UKCSI incorporates two sets of data to create a rolling measure of customer satisfaction. The July 2021 UKCSI includes responses from surveys conducted between 14 September to 12 October 2020 and 8 March to 6 April 2021.

45,000 customer responses

The UKCSI is based on an online survey of over 10,000 consumers, who are representative of the UK adult population by region, age and gender. The July 2021 UKCSI comprises 45,000 responses, 3,000 from each sector except for Transport and Utilities which include 6,000 responses each. Customers are asked to rate their experience of dealing with a specific organisation in the previous three months. Customers rate only one organisation per sector. Each customer can complete the survey for up to five different sectors.

Over 25 metrics of the quality of customers’ interactions and relationship with organisations

Customers rate the quality of their experiences and relationship with organisations on over 25 metrics including employee professionalism, product / service quality, ease of dealing with an organisation, timeliness, complaint handling and attitudes towards trust, reputation, an organisation’s customer ethos and ethical behaviour. Metrics reflect the priorities identified by customers, as well as attributes that show a strong relationship with overall customer satisfaction. The UKCSI also includes measures of customer effort and a Net Promoter Score (NPS). Customers rate organisations on a scale of 1 – 10 except for the question “how likely would you be to recommend xx to friends and family”, which is a scale of 0 – 10.

272 organisations received a UKCSI rating

These include 260 named organisations and 12 generic providers including “your local Council”, “your local restaurant/takeaway” etc. Customers select an organisation to rate from a randomised list of leading and emerging players in each sector which is reviewed before each UKCSI. Customers can also select an organisation to rate that is not on the list. Organisations which exceed a minimum sample size are given a score and are named within one of the 13 sector reports.

How the UKCSI is calculated

Index scores are expressed as a number out of 100. The UKCSI score for each organisation is the average of all of its customers’ satisfaction scores, multiplied by ten, with a weighting applied reflecting the priority score for each measure. The sector score is the mean average of all responses for that sector, multiplied by ten. The overall UKCSI is based on the mean average of each sector’s score.
