Tandem bank matters because it addresses the growing consumer demand for sustainable banking. According to a 2025 survey by Deloitte, 45% of UK consumers consider a bank’s environmental impact when choosing a provider. Tandem bank capitalizes on this by offering a green savings account that invests in environmentally friendly projects. Additionally, its cashback current account gives a percentage back on everyday spending at selected retailers, which appeals to cost-conscious consumers. In a market dominated by traditional banks, Tandem bank represents a shift toward purpose-driven, digital-first financial services.
