By partnering with Plain Numbers, Nationwide has “committed to put their customers’ needs at the heart of their work and provide communications that are easier to understand for those who struggle with numbers”.

Plain Numbers said this was especially important given the cost-of-living crisis, and showed the mutual’s dedication to help members understand their finances, make informed decisions and reach their financial goals.
