How we rate the best cash Isa and savings account providers

The Which? customer scores are based on a survey of an online panel of respondents from the general public, who were invited to take part in the savings account and cash Isa customer satisfaction survey during August 2016. The final sample size was 6,189.

The table above shows which of the 32 savings account providers that we were able to rate have the most – and least – satisfied customers.

Overall customer scores are worked out using a combination of overall satisfaction and how likely customers are to recommend their bank to a friend. Companies need at least 30 responses to be given a rating.
