Customer Satisfaction


At Volta, we are really proud of the NPS score that we have. It shows that our hard work as a data centre pays off and it’s great to see our efforts are being recognised.

Key points

A Net Promoter Score is an index ranging from -100 to +100 that measures the willingness of customers to recommend a company’s products or services to others. It is used as a proxy for gauging the customer’s overall satisfaction with a company’s product or service and the customer’s loyalty to the brand. Customers are surveyed on one single question. They are asked to rate on a 10-point scale the likelihood of recommending the company or brand to a friend or colleague. “On a scale of 0 to 10, how likely are you to recommend Volta to a friend or colleague?” Based on their rating, customers are then classified in 3 categories: detractors, passives and promoters.

What is a good Net Promoter Score?

NPS can be as low as −100 (everybody is a detractor) or as high as +100 (everybody is a promoter). An NPS that is positive (i.e., higher than zero) is considered to be good, and an NPS of +50 is excellent. At Volta, we pride ourselves of having an NPS, which is over 75. This means that our customers are very satisfied with our services and very likely to recommend us to friends or colleagues. According to a 2015 survey, the average NPS score for telecommunications was +7. With a score of over 75, Volta’s customers are 10 times more satisfied that the average customers in the telecommunication industry.
