  • Sector average score 50 Telecommunications in the UK
  • Knowledge & Expertise 43
  • Style of Communication 49
  • Speed of Resolving Problems 40
  • Valuing the Customer 43

After a flurry of movement in Q1 2024, the leaderboard for Telecommunications in the UK appears rather settled this month, with no changes in position in the leaderboard.

EE continues to lead the pack with an Overall Effort Score of 60. But the race is on, as Plusnet adds to its score for the second wave running, now on 57 thanks to boosts in its Style of Communication and Valuing the Customer scores. 

The majority of brands in other table have either improved or maintained their Overall Effort Scores this month, with the notable exception of Virgin Media, which remains in ninth. Unfortunately, this was corroborated by research from Which? last month when they named Virgin Media as the worst provider for Customer Service.

  • We are seeing score converge in this wave, with less to tell the top telcos apart across the CEI's main pillars. While this is a sign that the majority of telcos are offering the standard – more could be done to stand out from the pack.
We say Good customer service is essential in all industries, but in an environment where mid-contract price hikes are becoming increasingly common as brands try to make up the gap in rising costs, brands must utilise the right technology to ensure they are easier to do business with. If you're looking to communicate outages or prise rises, this has to be done proactively and using the right tone. We believe this is only possible through AI, which telcos are simply not investing in fast enough.

Customer Effort Scores for the quarter are presented in the rankings, ordered by highest Overall Effort Score first, to show which brand scored highest with its customers for that period. Individual brand ratings against the four pillars take us underneath that Overall Effort Score, with brand-specific explanatory analysis from the CEI Editorial team.

You can use the display above to toggle between score, ranking and individual pillars. Clicking 'Performance Tracker'  enables you to analyse the performance over time.

The Customer Effort Index is calculated using a self-referential scale that is recomputed every wave based on what the minimum and maximum values are. This enables us to see how each brand is performing compared to the others within the data set. See About for more on the methodology.
