Nationwide is the UK's largest building society, and is one of just a few companies to qualify for a Fairer Finance ribbon across five products.
One of Nationwide's strengths is its mutual ownership structure, which means it is owned by its customers, rather than private shareholders.
It has excellent customer happiness scores across all segments of its business, and its terms and conditions documents are generally written in plainer language than its competitors.
It holds Gold Fairer Finance Ribbons for current accounts, mortgages, savings and credit cards. It also holds Silver Fairer Finance Ribbons for personal loans.
