The Newcastle Building Society, very fittingly, is a UK building society, headquartered in Newcastle upon Tyne, England. The society was established in 1980, and as a relatively young building society, is a merger of two older ones: the Grainger and Newcastle Permanent Building Society. However, in 2006, Newcastle followed its own precedent for merging, and merged with another local society, the Universal Building Society. This said, the Newcastle Building Society is one of the UK’s largest of the kind, with a large member base and assets totalling over £4.4 billion; furthermore, the society is still a mutual. The Newcastle Building Society offers competitive rates across its products, which includes savings, investments and mortgage accounts, insurance services and credit cards.

Call Newcastle Building Society’s national telephone contact number 0345 734 4345 for general enquiries about their interest rates and to open a new mortgage, savings account or investment fund. Calls to their customer service number are charged at normal UK rates.
