Kingdom Bank Launches New Cloud-Based Digital Banking Suite with Sandstone Technology

Kingdom Bank has successfully launched a new digital banking suite powered by Sandstone Technology, introducing native mobile applications and automated onboarding for its UK customer base. The move signals a significant modernisation for the niche lender, prioritising cloud-based scalability and improved digital accessibility for its retail and non-retail deposit products.

What was announced

The implementation introduces a comprehensive digital banking overhaul for the UK-based Christian bank, delivered through the Sandstone Cloud Service (SCS) platform. This cloud-hosted environment is designed to provide the security and resilience required for modern financial services while allowing the bank to scale its operations more effectively without the constraints of on-premise infrastructure.

Central to the rollout is the BankFast Apply module, which facilitates digital deposit origination and onboarding across both retail and non-retail product lines. This is complemented by BankFast Online and a native BankFast Mobile App, providing customers with 24/7 access to account management tools that were previously unavailable. The solution allows users to manage their accounts through a unified interface, whether they are accessing services via a desktop browser or a smartphone.

The transition was executed as a single-release programme, aimed at establishing a secure foundation for the bank’s future growth. Early performance metrics indicate a high level of engagement from the bank's existing user base; within the first month of the platform's launch, more than 35% of customers had already migrated to the new digital experience. By moving to a native app and streamlined web interface, the bank aims to reduce friction in the onboarding process and improve the overall lifecycle management of its deposit products.

The companies involved

Kingdom Bank Ltd is a UK-based financial institution that specialises in providing banking services tailored to the Christian community. As a niche lender, it focuses on values-led banking, offering mortgage and savings products to individuals, churches, and charities. The bank operates within a competitive UK specialist banking sector where digital transformation has become a prerequisite for maintaining relevance among younger, tech-savvy demographics within its core community.

Sandstone Technology is a global provider of digital banking solutions, headquartered in Australia but with a significant presence in the UK and European markets. The company specialises in end-to-end digital banking platforms, including origination, digital banking channels, and AI-driven automation. Sandstone has established itself as a key partner for mid-tier and specialist banks looking to modernise their legacy systems without the overhead of building proprietary technology from scratch. Its product suite, including the BankFast range, is designed to integrate with various core banking systems, providing a front-end layer that emphasises user experience and operational efficiency.

What FF News has reported before

FF News has followed the digital evolution of Kingdom Bank closely, previously reporting on its infrastructure upgrades in Kingdom Bank Goes Live on Temenos SaaS to Scale Values-Led Banking Services. This move to Temenos provided the back-end foundation that Sandstone’s front-end tools now sit upon.

Sandstone Technology has also maintained a consistent presence in our coverage of the UK banking sector. We recently detailed their work with another digital-first player in Chetwood Bank Partners with Sandstone Technology to Accelerate Launch of New Digital Savings Platform. Furthermore, the company’s industry standing was highlighted when they were featured in The Fintech Magazine Issue #31 and recognised during the selection process for The Finalists Announced for the 2025 FF Awards.

What this means

This partnership highlights a critical trend in the specialist banking sector: the "consumerisation" of niche finance. For years, values-led or community-focused banks could rely on customer loyalty to overlook lagging digital interfaces. However, as neobanks set a high bar for user experience, specialist lenders are under immense pressure to modernise or risk irrelevance. By adopting a cloud-hosted, native app-first strategy, Kingdom Bank is attempting to bridge the gap between its traditional mission and modern consumer expectations. The rapid 35% migration rate suggests a significant pent-up demand for digital tools within even the most traditional banking communities, raising questions for other specialist lenders about how long they can afford to delay their own digital migrations.
