Abstract: The Government of India liberalization and globalization of financial reforms strongly recommended operational flexibility and functional autonomy to bank to enhance efficiency and productivity along with deregulation in interest rates, substantial reduction in statutory reserves and entry of new banks in the private sector to engineer and encourage competition. In the deregulated, competitive and ever demanding customer’s market retaining the existing customer and attracting new customer is very important. Customer acceptance and customer preference to banks play an important role in the success of their functioning. This paper explores the customer perception towards service quality attributes among public sector banks and private sector banks.
