Swindon-based building society Nationwide has been named Bank Brand of the Year at the Which? awards.
Britain’s largest building society claimed the banking award for the second time.
Peter Vicary-Smith, Which? chief executive, said: "The company offers a great range of financial products and is a Which? Recommended Provider for current accounts, credit cards and mortgages.
"Nationwide gained more current-account switchers last year than any other bank or building society – showing that customers recognise it’s doing a great job.
"Consumers should be at the heart of every business. Brands that deliver excellent products and services for their customers deserve to be recognised and rewarded.
"The Which? Awards winners list honours the commitment of those businesses that strive to meet the expectations of consumers and go above and beyond to respond to their needs."
There was also success for Malmesbury-based Dyson, named runner-up in the Large Appliance Brand of the Year behind Samsung.
Finalists in the awards are nominated by Which? experts using research, testing, endorsements – such as Best Buy and Recommended Provider status – and feedback from Which? members and the general public throughout the year. Businesses cannot nominate themselves.
