Over the years, a significant amount of building societies have gone on to become public limited companies but Nationwide is one that has stuck to their origins. As a result, they are now the largest building society in the world with 18,000 employees. In addition to this, they are second in terms of mortgages and savings in the UK and this has been helped along by acquisitions of Anglia Building Society and Portman Building Society.
According to the company themselves, the earliest parts of their business formed around the 1840s and they have gone from strength to strength ever since. As a mutual company, all customers are seen as members and they have an opportunity to vote at the AGM and take a slice of the profits. As of 2017, they have over 700 branches in the UK and a number of ATM machines and other services.
