Company History and Business Evolution

OSB Group traces its roots to 2011 when it was established as OneSavings Bank plc, a new entrant in the UK banking sector. The bank quickly gained traction by focusing on niche lending markets overlooked by traditional high street banks. In 2014, the company acquired Kent Reliance Building Society's lending and savings business, significantly expanding its branch network and customer base. This acquisition was a pivotal milestone, doubling the group’s assets and establishing a strong foothold in the South East of England.

Over the next decade, OSB Group continued to grow through strategic acquisitions and organic expansion. In 2017, it acquired the commercial lending platform of Prestige Finance, enhancing its buy-to-let and commercial mortgage capabilities. The following year, the group rebranded to OSB Group to reflect its diversified portfolio and broader market presence. The IPO in 2016 on the London Stock Exchange raised significant capital, fuelling further growth and innovation.

In 2021, OSB Group reached a major milestone with total assets surpassing £20 billion, driven by increased demand for specialist mortgages during the post-pandemic housing boom. The company invested heavily in digital technology, launching an online mortgage application platform and mobile banking app for savers. More recently, in 2024, OSB Group expanded into the green lending market, offering energy-efficient home improvement loans and sustainability-linked savings accounts. This evolution underscores OSB Group's commitment to innovation and adaptability in a rapidly changing financial landscape.

Mission, Vision, and Core Corporate Values

OSB Group’s mission is to deliver specialist lending and savings solutions that empower individuals and businesses to achieve their financial goals. The company’s vision is to be the UK’s leading challenger bank, recognised for customer-centric innovation, operational excellence, and sustainable growth.

Agility enables the group to respond quickly to market shifts, while Responsibility underscores its commitment to environmental, social, and governance (ESG) principles.

These values are embedded in daily operations, from product design to customer service.

Sustainable growth targets include expanding the green lending portfolio to £1 billion by 2027 and achieving net zero operations by 2050.

Future roadmap milestones include launching a new savings platform in 2025, expanding into the SME lending market, and increasing the share of digital sales to 70% within three years. The group also plans to open two new regional offices in Manchester and Edinburgh to support national growth. These strategic initiatives are designed to enhance shareholder value while maintaining a robust risk appetite and regulatory compliance.
