Who we are

Whether you are an existing client, or considering becoming one of our clients, we are delighted that you want to find out more about TIAA.

Specialist business assurance

We stand out from the crowd

TIAA is distinct from other providers because we are a specialist business assurance organisation rather than a general accountancy firm.

Providing assurance for over 25 years

TIAA began trading in 1995, and since then, we have grown significantly. We have taken on the operations of several other business assurance providers, making us specialists in various sectors, and turning us into a nationwide operator with a multi-million pound turnover.

Originally formed by a consortium of housing associations to meet the specialist internal audit needs of the social housing sector, TIAA began trading in 1995.  We are now one of the largest business assurance providers to this sector. Today we provide business assurance services across Housing, the NHS and Healthcare, Local Government, Education, Charities, and Police sectors. We are comprised of four regional business assurance Directorates which are supported by national IT Audit, Business Services, Anti-Crime, Security Management and Digital Forensic teams, together with a centralised Business Support function. With offices across England, Wales and Scotland, we can offer you a genuinely local service.

We continue to go from strength to strength, gaining new clients and enjoying a high rate of reappointment by current clients.  TIAA stands out in the field because we are not an accountancy firm, but a specialist provider of internal audit, anti-crime and business assurance services.  We have a strong reputation for providing an intelligent business assurance service, rather than a ‘tick box’ solution.

Our purpose

We put our relationship with clients at the heart of the way we do business.  We sincerely care about each and every client, which is one of the reasons so many of our clients reappoint us.

Our success is underpinned by our commitment to corporate responsibility. We care about our clients, our staff and our community.

We are not a multi-national, faceless, impersonal organisation. We pride ourselves on being approachable and treating each client as an individual: you will never be just another number to us. Our clients will always be at the centre of everything we do.  We know that each organisation we work with has their individual challenges and requirements. That is why TIAA never delivers a standard service, but a truly personalised one created in partnership with you.

From the very start, we will liaise closely with you to understand the particular risks and issues your organisation faces. TIAA’s approach places you at the heart of our business, ensuring that our plans, our work, and our delivery are specifically tailored to you.  We seek to earn your trust and loyalty, not only through the high quality of the service we deliver, but also through the strength of the personal relationship we build with you.

As our client, you will have our attention whenever you need it because we care about you.

Demonstrating our commitment

Every accreditation or award that we achieve helps us to perfect our procedures of work. Whether it’s based on quality or environmental impact we aim to ensure that we are always improving and monitoring our success.
