The Cumberland has taken top spot in the latest Fairer Finance rankings for customer experience for savings customers.
The independent survey also found that the building society had the happiest customers in the same category.
Fairer Finance, a consumer group that focuses on the banking industry, compiles its rankings every six months and companies appear only if they return a statistically significant sample in its poll of over 23,000 bank and building society customers across the UK.
The rankings aim to find out what people think of their financial provider, how well they handle complaints and how transparent they are.
The Cumberland topped the table of 50 of the UK’s savings providers and its customer happiness score of 78 per cent was also the highest in the sector.
Alongside its top ranking for savings customers, The Cumberland also achieved a gold ribbon having been rated second in the overall rankings for customer experience.
Chief executive Des Moore said he was ‘absolutely thrilled’ to win the award ‘against stiff national competition’.
“I am so proud of the hard work from all of our teams culminating in this award and having the happiest customers in the UK too.”
Nigel Taylor, head of marketing at The Cumberland, said: “We’re always extremely proud to hear just how highly our customers rate us.
“Providing exceptional customer experiences is central to everything we do, and if our customers are happy then we are happy.
“We never rest on our laurels at The Cumberland, and we know the hard work and dedication it takes to maintain these rankings. We’re always looking at ways to improve and develop to ensure we can continue to make banking brighter for everyone in our region.”
