Insights

Growth & Expansion OSB Group has expanded through the 2019 Charter Court integration and serves the UK, Jersey, and Guernsey with a diversified brand portfolio, signaling opportunities to cross-sell and upsell across mortgage, development finance, and specialist lending products to a broader intermediary network.

Intermediary Focus The groupOriginates almost all organic lending through specialist intermediaries, supported by a dedicated intermediary sales leadership. This presents a clear path for sales outreach to broker networks, with potential for enhanced distribution partnerships and referral programs.

Leadership Changes Recent executive appointments including a new CEO and group head of intermediary sales indicate a strategic push and potential openness to new partnerships, product pilots, and accelerated onboarding with external lenders or technology partners.

Tech & Security OSB relies on a mix of cloud and security technologies, with notable vendors and digital platforms. This environment may be receptive to advanced fraud prevention, underwriting automation, and fintech integrations to streamline broker-to-lender workflows.

Funding Model Predominantly funded by retail savings via online channels, OSB’s model emphasizes efficient operating structure and bespoke underwriting. There may be opportunities to discuss funding-aligned services, wholesale savings partnerships, or ESG-aligned deposit products to support growth.
