Our value proposition

Our audit firm offers easy access to the principals on audit matters and a personal approach that contrasts with  the larger firms.

Our specialist experience in not-for-profit sector audits means that typically we have solved problems before you have experienced them.

We will continue to re-design and modify our audit approach to suit your expansion. This means regular dialogue and consultation on emerging matters as well as extensive interim audit work to monitor and report on internal control systems.

You will be our priority. We will provide the assurance you need as you grow.
