TIAA

What TIAA does

TIAA Limited is a UK-based specialist business assurance provider founded in 1996 and headquartered in Fareham, England. The firm delivers internal audit, IT audit, cyber security, anti-crime, security management, HR investigations, and advisory services exclusively to the UK public sector — principally social housing associations, NHS trusts and ICBs, local government bodies, education institutions, and charities. Its stated revenue for FY2025 is £10m, and it operates with 101–250 employees as the sole trading subsidiary of AIM-listed Adsure Services PLC. The business is differentiated by a deliberate refusal to offer financial audit or tax services, which removes conflicts of interest and positions it within UK public sector procurement frameworks; it holds B Corp, ISO 14001, Cyber Essentials Plus, and CIPFA substantial assurance credentials to support tender eligibility.

The core service catalogue is augmented by four proprietary / productised offerings: TIAA Insight (an AI platform co-developed with the University of Essex via an Innovate UK Knowledge Transfer Partnership, positioned for anomaly detection and to underpin the parent's AI-driven acquisition strategy), Praetorian (a counter-terrorism maturity framework tool aligned with Martyn's Law enforcement from April 2027), Sentinel (a strategic security and resilience methodology), and CQC Care Align (a Care Quality Commission compliance service for healthcare clients). Supplementary offerings include Top-Up Audits, Health & Safety Reviews, DSPT Independent Audits for the NHS, and a subscription vulnerability-scanning service (Secure Scan).

TIAA's revenue model is professional services delivery — principally multi-year assurance engagements and project-based advisory — sold direct to public sector buyers via field/enterprise engagement, with go-to-market supported by content marketing (TIAA Hub), sector events, social channels, and targeted newsletters (Security Focus, Fraud Stop, Insight). The firm's stated strategic intent, channelled through parent Adsure Services PLC, is to evolve from a single trading subsidiary into a diversified cluster of specialist professional services firms using an AI-led roll-up, and to spin out a dedicated AI solutions subsidiary to commercialise TIAA Insight beyond internal assurance work.
