The study adopted the survey research design using primary source of data with questionnaire as instrument of data collection. A total of 100 copies of questionnaire were administered, out of which 82 questionnaires were duly filled and returned.

The success rate of business organizations is undoubtedly dependent on their ability to establish customer satisfaction and brand loyalty (Iddrisu, Nooni, Fiankoc & Mensah, 2015). This is particularly true in the service industries, where connection with customers is critical to ensure that the organization outperforms its rivals and excels in service delivering. The establishment of long-term, value-added relationships with customers is the heart of marketing, among many other services (Agbemabiese 2015). Organizations must recognize the vital role of customer retention via providing excellent services in order to secure long-term profitability and achieve good financial returns. In the contemporary competitive market, quality of service and customer retention are regarded as vital to a company’s success and sustainability (Ibojo, 2015). Service excellence necessitates regular anticipation of what customers expect from the service provider.

Reliability and quality in business organization, according to Kemp & Rotmans (2005), has transformed into a standardized indicator for how well the service rendered meets the expectations of the customers. In light of this , businesses have understood that in order to improve profitability, they ought to concentrate on the quality of services they deliver to their patronizers. It is essential to know the customers’ needs in order to give acceptable quality service. In a service oriented business, customers and front-line workers engage customers to generate the service (Rita, 2008). Effective interaction, in turn, is based on the abilities of front-line service personnel as well as the processes proceeds (Kotler & Armstrong (2012), cited in Ivanauskiene (2014). Unlike manufacturers, the quality of services rendered will always vary based on staff-customer engagements. Customers are essential to the banking industry’s entire range of operations and revenue generation. Customers are demanding, thus acquiring and maintaining them has become a prime priority. According to Siew-Peng & Sedigheh (2015), banks must build a good relationship with their customers in order to retain them, safeguard and support their long-term interests. According to Berry, Parasuraman, & Zeithaml (1988), cited in Siew-Peng et al.(2015), service quality is a success factor, the most effective and competitive instrument, and the strength of top service businesses. Given the increased competition in the financial sector, banks must assess the quality of their services in order to retain customers. This study will therefore examine the impact of service quality on customer retention in Nigeria’s banking sector.


The progressive and incremental transition from conventional orientation to aggressive push is one of the primary developments in Nigeria’s banking sector today. As a result, management is obliged to leave their shells or enclaves in order to share the wide market and serve the diverse wants of customers. It’s crucial to note that customer satisfaction and service quality are inextricably linked. According to Jayaraman, Shankar, & Hor (2010), the higher the service quality provided by an organization, the higher the level of customer satisfaction.

As a consequence of the above, banks operating in Nigeria are under a great deal of pressure as a result of increasing competition in the industry (Evangelos, 2014).

As a result, various strategies are devised to retain customers with the aim of improving service quality. Service quality is very important in the banking sector since it ensures high customer satisfaction, making it a key to competitive advantage. Customer satisfaction and willingness to recommend the service to a friend drop when customer service is poor. Service quality has several dimensions, and each customer prioritizes each dimension differently (Ahmad & Kyriaki, 2009). Furthermore, service providers’ perceptions of service quality may differ significantly from customers’ perceptions of service quality. It is critical to understand the customer’s perception and expectation of quality service if banks are to compete in delivering quality service to customers (Siew-Peng & Sedigheh, 2015). Hence, service quality measures should be derived from the viewpoint of customers in order to guarantee that their needs and expectations are satisfied, as this will increase customer retention.
